Λ Π G Group Ministry of Economy, Central Development Department, Co-operation and Production Cooperative Du Yin 31 V. Description of the invention () The present invention is like a blue two-stroke internal combustion engine lubrication method and lubricant supply system. As we all know, the advantages of the two-stroke internal combustion engine are the simplicity and high output of the specified exhaust volume. What has been implemented so far is to mix the lubricant and the fuel consumed by the engine, thereby lubricating the two-stroke engine. However, although this lubrication method is simple and low cost, it fails to properly control the lubricant consumption. That is, when fuel and lubricant are mixed, it is necessary to ensure that the mixture can meet the most demanding operating conditions. As a result, lubricants are supplied under most operating conditions. In order to avoid these problems and ensure better lubrication, lubrication control and reduction of lubricant consumption, it has been proposed to use a separate lubrication system for two-stroke engines. This type of separate lubrication system uses pumps to draw lubricant to the engine for lubrication. This lubricant can be delivered to the induction system of the engine, directly to the parts to be lubricated or both. Generally, to supply lubricant, reciprocating pumps driven by engines are used. This type of pump has the advantages of properly controlling the lubricant supply and being able to deliver a smaller amount of lubricant. However, the amount of lubricant supplied by this pump is directly related to the engine speed, and the engine's lubrication requirements are not necessarily related to it. In the past, one of the methods to control the suction of lubricant oil was either to change the stroke or to use an overflow valve that actually changed the stroke of the pump to control the effective stroke of the lubricant pump. In this way, the amount of lubricant suction was controlled. Figure 1 shows a graph of the lubricant control method of the conventional system and the actual lubricant demand of the engine. This diagram is a pseudo-chart showing the relationship between engine speed and lubricant quantity. Usually the amount of lubricant supplied to the engine is controlled along a curve (such as the curve "a"), of which (please read the back-up notes first, Er Xiangmu, Α) the paper size is used in the fflfi family dazzle ( CNS) TM regulation tft (public goods at 0x207) -3- 81. 6. 10,0⑻ 汴 (Π) L01SG3 Λ 6 Β 6 Printed by 7 * Ministry of Central Government and CX 工 消 # Cooperative Society 3i V. Description of invention ( ) The output of the lubrication pump changes according to the position of the accelerator or throttle. It can be seen from the figure that the supply of lubricant increases from a prescribed engine speed to a maximum along a slope, and then remains the same. The dashed curve "b" pseudo-displays the actual lubricant demand of the engine. As shown, using an approximate curve of throttle or accelerator position can relatively closely match the engine's lubrication requirements over a wide range of steady-state conditions. However, since the control of the lubricant changes in response to the position of the throttle valve, and the position of the throttle valve changes more quickly than the engine speed, this type of control will produce excessive lubricant under transient conditions. The point cut curve “c” in Figure 1 shows the effect of the operator suddenly opening the throttle. When this effect occurs, even if the engine speed does not increase in the same proportion, the lubricant increases rapidly. In addition to the aforementioned shortcomings, the use of mechanisms to change the stroke of pumps or ytterbium valves also requires higher-priced pumps and possible mechanical accidents. Therefore, in order to overcome the above problems, a lubricant supply system has been proposed. In the system, a return passage is connected to the lubricating oil supply passage, and a three-way electromagnetic control valve is connected to selectively supply the lubricant supplied from the oil pump to the engine (the flow state of the control valve) or discharge the return The channel (the non-flow state of the control valve) to return the oil supplied from the oil pump to the suction side of the aforementioned pump. Such a control valve is preferably composed of a helical tube controlled by a task (Japanese Patent Laid-Open Publication Hei 2-1 39307). In terms of this conventional system, a three-way solenoid valve with a task control is used in this system; when any excess stream oil controls the load ratio of the solenoid valve according to the operating conditions, thereby returning to the suction side of the oil pump , The engine is available (please read the countermeasures first. ¾ then rewrite this page> install _ this paper ft scale selection Zhongming "Home« Bi (CNS) T4 specifications (210x297 male dragon) -4-81 . 7. 20,000 * (II)

An appropriate amount of lubricant in accordance with the operation of the engine. However, it is difficult to come up with an appropriate control strategy for setting the electromagnetic load ratio. That is, if a plunger-type engine-driven lubricating oil pump is used, the reciprocating time of the plunger changes with the engine speed and the setting of the control time; the three-way control valve opens the supply channel to supply lubricant The cycle for the engine is moved from the leading cycle of the pump plunger. This lead period causes the engine's lube oil supply to become incompatible with the electromagnetic threshold control I load ratio. On the other hand, if the mission control time or mission control is too long, the responsiveness of the oil supply, for example, during rapid acceleration, may become insufficient. Moreover, in addition to the above-mentioned problems, even by controlling the three-way solenoid valve by task, it has proved difficult to supply lubricating oil that meets the instant engine operating conditions. In particular, once the lubricating oil is allowed to be supplied to the supply passage side of the control valve, the amount of lubricating oil supplied to the engine cannot be changed until the start of the next control cycle. For example, if the engine finishes closing the throttle valve to accelerate quickly while operating at high speed and supplies a large amount of lubricating oil, although the engine is converted to less oil by deceleration, the lubricating oil is still suitable for high The supply ratio of the speed transfer state is supplied to the engine. That is, the amount of lubricating oil supplied to the engine often exceeds the required amount, and white smoke is easily generated from the exhaust pipe due to the excessive amount of combustion oil. Moreover, when supplying lubricating oil through the opening of the task control solenoid valve. In the case of transient operation of the engine, for example, when the current supply of lubricating oil due to engine rotation at low speed is low, such as when the throttle is suddenly turned on The rapid acceleration of the valve often causes the problem of incorrect fuel supply.

Description of the invention () Finally, when the spiral tube receives a driving multiple to open and close the control valve, the valve body should often be delayed, Therefore, if the influence of the delay of the control valve is not included in the control measures, the predetermined supply of lubricating oil will become incorrect. In order to minimize the shadow honey of the control valve body's hydroxy-prolonged operation, therefore, in order to improve the accuracy of the oil supply, the supply cycle (transmission cycle) should be extended as much as possible. This helps to maintain the characteristics of the control valve's extended response independently of the supply cycle, and therefore, the effect of the error caused by the response of the hydroxylated valve becomes smaller when the supply cycle is extended. On the other hand, when the lubricating oil returns to the suction side of the oil pump (including the tank) toward the return channel, the extension of the supply cycle also causes the return cycle to be extended. Therefore, if the engine operation condition changes suddenly as the engine oil consumption increases suddenly, and at the same time, the lubricant is not supplied to the engine side at that time, when the engine is running at a high speed, it is likely that insufficient lubrication of the engine will occur Affection. In order to summarize the difficulties of the known mission control solenoid valve (suitable for measuring the appropriate amount of lubricating oil of the engine), we should note that especially under transient conditions, the amount of lubricating oil supplied to the engine is not as expected Changes in the operating conditions. Therefore, the main purpose of the present invention is to provide an improved lubrication method for a two-stroke internal engine, in which the amount of lubrication supplied to the engine is so that it can be closely adapted to the engine operating conditions even under transient conditions. Moreover, an object of the present invention is to provide an improved lubrication system which is suitable for carrying out the above-mentioned improved lubrication method, and is preferably suitable for breeding. According to the present invention, the above object can be achieved:

Description of the invention () (please read-back (Note: Bian Xiang traces hardships) The lubrication method operates a control valve in response to the operation of the engine, thereby changing the time period of the control valve in the flow state or the non-flow state to control the lubricant delivered to the engine. . According to a preferred embodiment of the present invention, the control valve is actuated by the solenoid, and a control unit provides a load ratio and / or task control period, that is, one of the solenoids ΟΝ / OFF (on / off) Cyclic control. Moreover, it is advisable to provide the flow state (flow position) of the control valve during the OFF state of the spiral tube. In this state, lubricating oil can be injected into the engine from the valve; conversely, when the lubricating oil supply to the engine is blocked but supplied by the fuel tank The lubricating oil is recirculated to the suction pump of the oil pump through the control valve or directly sent into the oil tank provided upstream of the oil pump, and the non-flow state (non-flow position) of the control valve is established during the activated ON state of the solenoid. According to this method, it can be advantageously ensured that even in the resting state where the control valve is lost and the control valve is in a non-active rest state, sufficient lubrication of the engine is performed anyway. The Ministry of Economic Affairs ’Standards and the seal of the ABC Cooperative Society 31 In order to properly restrict the oil supply to variable operating conditions, it is best to obtain the flow state of the control valve when it remains inactive, and to assume its non-flow state when starting. , Shortening the task control period of the spiral tube as the engine speed increases, and extending the task control period of the screw as the engine speed decreases. Moreover, it can also be considered to quickly turn over the opening speed of the engine throttle in the same way; where the task control period should increase the opening speed of the throttle. In particular, the opening speed should be increased and shortened rapidly. Through this method and its preferred embodiment, an appropriate amount of lubricating oil can be supplied to the engine immediately following the changing engine operating conditions. For example, when the task control cycle is shortened due to the increase in engine speed and extended due to the decrease in engine speed, 81. 6. 10,000 sheets (II) of this paper are used in the standard a® family standard (CNS) * H regulations.

Description of invention () The delivery time of the lubricating oil pump is consistent with the task control period, and The supply of engine lubricating oil is controlled to be in accordance with the selected load ratio, that is, an appropriate amount in accordance with the operation of the engine. In addition, when the task control cycle is shortened due to the increase in throttle opening speed, the lubricating oil supply of the engine can be improved. According to other preferred embodiments of the present invention (suitable for making the oil supply closely follow the engine operating conditions, especially transient engine operating conditions), alfalfa will first supply the majority of the optimal amount of lubricant to the engine under certain engine operating conditions The load ratio is stored in the memory device of the control unit; then the instantaneous operation condition is detected and the instantaneous load ratio is detected; then the previously calculated load ratio is modified to be close to that read from the engine operation condition detection billion device Predetermine the optimal load ratio; then self-adaptive control of the previously calculated load ratio (until the calculated load ratio is equal to the storage optimal load ratio corresponding to the circumstantial operation), leading to the following functions: engine oil The supply volume can be changed without delay following the changing operating conditions and the lubricating oil can always be supplied at the optimum setting. Incidentally, a task control cycle includes a lube oil supply cycle and a lube oil return cycle, and when one of them changes, whether it is the lube oil supply cycle or the lube oil return cycle, it remains unchanged by this calculation The load ratio is corrected. In particular, oil injection into the engine is controlled by changing the variable lubricant supply cycle or the end of the lubricant return cycle. At least one of them can be changed according to the operation of the engine. According to yet other preferred embodiments of the present invention, the OFF (off) period of the spiral tube can be kept unchanged, while the ON (on) period can be changed; and (please read first-the note to the contrary Difficult " Muying) This paper scale is free to use the Chinese National Standard (CNS) nM specification (210x297 gong) 81. 6. 10,000¾ (ΙΪ) Ten Central Standard 1 of the Ministry of Economic Affairs; ΓΠ 工 消 # Cooperation du printing λ f; _ η r) _ V. Description of the invention () Set the OFF period to a value that can ensure the minimum oil required to run the engine to be supplied. According to yet other preferred embodiments of the present invention, the OFF period of the coil tube can be set to change with the engine operation (especially in a stepwise manner at a fixed rate according to the engine winding speed), and the ON period on the other hand It also changes with the engine operating condition; that is. In this embodiment, the lube oil supply cycle and the lube oil return cycle can be changed in different ways, so that not only the load ratio of the solenoid control valve but also the adjustment control according to the load control cycle The amount of lubricant delivered to the engine. Therefore, the task control cycle can be changed according to the load ratio of the instantaneous operation. According to yet another preferred embodiment of the present invention (the control method implemented by the control unit of the control valve), a calculation method is used to detect the engine rotation speed during the supply of lubricating oil to the engine ( The number of revolutions) and the amount of lubricant required to determine the period of oil supply interruption. In addition, another control method of the control unit is to calculate the amount of oil consumed by the engine in response to the detected engine rotation speed, throttle opening state, and time elapsed from the last transition of the control valve, so as to establish lubrication The flow of oil back to the oil pump again; when, when the amount of oil supplied to the engine is roughly equal to the calculated amount of oil consumed by the engine, the control valve is converted from its non-flow state to its flow state by means of a timer. Set the re-start period of fuel supply to the engine. According to this method, when the oil is exhausted during the preceding cycle, the engine oil is re-supplied. Therefore, an appropriate amount of lubricating oil can be supplied from time to time, and white smoke can be avoided due to the excessive supply of fuel. According to the preferred embodiment of the aforementioned control strategy. While the OFF period of the solenoid of the control valve is kept unchanged, its ON period varies with the engine operation (please read the notes on the back # 堀 巧 木 0) this paper Scale-side use China National Standards (CNS) 1M specifications (210x297 gm) — 9 — 81. ti. 10,000¾ (II)

In order to implement the functions shown above, it is used to set the supply of new oil to the engine The timer means at the beginning, that is, the amount of oil consumed by the engine minus the amount of oil consumed by the engine, and when the final value becomes zero or negative, the difference is slightly divided in order to switch the control of the spiral coil. Also, in this example, even if the loss of parts of the control unit occurs, proper lubrication of the engine can be guaranteed as a safety measure. For this purpose, the oil supply is set after integrating the results of the deduction The timer means at the beginning of the period, that is, during the establishment of the return flow of the lubricating oil back to the suction side of the pump, compare whether the oil return period is longer or shorter than a predetermined period, so that when the aforementioned oil return period is longer than the current period, the amount of The integral result of the reduction in oil consumption is disconnected irrespective of the method. According to this method, regardless of the result and the number provided by the calculation means of the control unit, the control valve can be guaranteed within the predetermined cycle Return to its flow state after the period has elapsed. According to yet another embodiment of the present invention. Provide control countermeasures: keep the lubricating oil supply cycle unchanged; meanwhile, a period of oil supply start period is used to interrupt the oil return period so as to run with the instantaneous engine The control valve from the flow state to the non-flow state. In the latter case, the calculation method of the control unit is based on the detected engine rotation speed and calculates the required amount of lubricating oil. The calculation means should detect the speed of rotation, the opening state of the throttle valve and the time of the last transition of the self-control threshold, and calculate the amount of oil consumed by the engine. In order to establish the return flow of lubricating oil back to the suction side of the oil pump; A detection means is used to detect the residual amount in order to switch the control valve from the non-flow state to the flow state when the aforementioned oil supply amount and oil consumption amount are approximately equal to each other.

At this time, an engine fuel supply suitable for the instantaneous engine condition can be obtained. In particular, the engine speed can reflect the engine operation. In addition to this effect, The lubricating oil supply of the engine can be tightly connected to the operating condition of the engine through this embodiment of the present invention, and thus can be adjusted to the actual amount required to lubricate the engine. The embodiment described later leads to an effect: that is, the Operation delay can be reduced by extending the lubricating oil supply cycle.

Regarding the first embodiment of the present invention, as shown in FIG. 2, in terms of its apparatus, the aforementioned figure shows a lubricating oil supply system. This supply system, such as the lubrication system described below, assumes that the designer according to one embodiment of the present invention implements a method of supplying an appropriate amount of lubricant to the engine according to the first embodiment of the present invention. The aforementioned lubrication system 1 is designed to supply lubricant to a two-stroke internal combustion engine 2. The lubricating oil supplied to the engine 2 by the system 1 can be supplied to the induction system of the engine 2, or can be directly supplied to various parts of the engine to be lubricated through a direct lubrication method or a combination of these systems. Therefore, we should know that all known types of lubricant delivery systems in engines can be used in conjunction with lubrication systems. The lubrication system 1 includes an oil tank 5. Lubricant (oil) is supplied to the oil tank 5 to a reciprocating lubrication pump 3, hereinafter referred to as an oil pump 3. This pump is driven by the engine 2. A conventional plunger oil pump 3 can be used. As shown in Figures 3a and 3c, the output of the pump is approximately the same for each suction cycle. Thus, as the engine speed increases, the number of pump pulses generated during a specified time increases. As a result, as the engine speed increases, the output of the oil pump 3 also increases. Figure 3a_ shows that the pump is outputting at a low speed, while Figure 3c shows that the pump is outputting at a high speed. A supply passage 4 is pseudo-connected to a control valve, in particular, a three-way solenoid-actuated control valve 8. The control valve includes a roll-type valve 10, which is slidably received in the bore of the valve housing 9. A spiral tube coil 12 is provided, and an excitation current for actuating the valve body 10 is provided to switch the aforementioned control valve 10.

Description of the invention () A return spring 11 # is placed in the first position in the normal position of the valve body 10 as shown in FIG. 2; where, The valve body 10 is located at a position where it communicates with the supply port 9a, that is, the supply passage 4 is communicated upstream of the valve body 10 and another part of the supply passage 4 is communicated downstream of the valve body 10 to the engine 2. The supply The downstream part of the channel 4 delivers lubricant to the engine lubrication system. When the solenoid coil 12 is demagnetized, the valve body 10 is pulled up to compress the return spring 12, and then the supply port 9a is blocked to allow the oil to be delivered from the oil tank 3. The supply channel 4 to the control valve 10 communicates with the return channel 7 to deliver oil back to the guide channel 6 on the suction side of the oil pump 3 to detour the aforementioned oil pump 3. As a result, when the control valve is in its non-flowing state, the spiral tube When the coil is excited, the pressure output from the oil pump 3 returns to its suction side, so there is no lubrication From the supply port 93 to the engine 2. The solenoid coil 12 is excited by a circuit including a battery 15 and a main switch 14. These components supply power to a control unit 13 (CPU). The control unit 13 is designed with The program for supplying predetermined pulses to the helical coil 12 according to the sensing engine conditions. These conditions may include the engine speed supplied from a suitable engine speed sensor and an accelerator position sensed by an appropriate throttle position sensor. In addition. Other conditions Such as throttle valve opening speed, engine operation and environmental conditions, can be input to the control unit 13. As shown in Figures 3b and 3d, when the control unit 13 outputs an excitation multiple of a time period b, the control valve is in its Non-flowing state (excited) without lubricant supplied to the engine 2. In the OFF cycle, the solenoid coil 12 is excited again and the valve body is at the lowest position as shown in Figure 2 (control During the period of the flow state of the valve 10), the lubricating oil is delivered for a period of time (please note the back-to-back considerations).

Description of the invention () a (Yi control Xunchen control cycle, hereinafter referred to as task control cycle) Decrease b (a ~ b), therefore, the amount of oil delivered during a specified time period is determined by the load ratio A minus B (stroke A multiplied by 100%). It must be noted that since the oil pump is The speed of the engine 2 is driven in proportion to the constant speed, so when the engine is running at a higher speed, the shorter time interval of re-excitation of the helical coil 12 will provide an oil flow greater than the same time period. The time interval, that is, the task control period a is adjusted in proportion to the engine speed, and as shown in Figure 4, it is designed such that when the engine is running at a low speed, the task control period a is greater than the engine shown in Figure 3d The higher speed runs for a longer time. The duty cycle is determined according to the actual needs of the engine, and then programmed into the control unit 13 to supply the appropriate amount of lubricant for all engine speeds. This method prevents excessive oil supply and smoke in the exhaust. M: " 'Ministry of the People ’s Republic of China quasi-sponsored and printed by the co-operative cooperative 5i However, as mentioned earlier, only controlling the duty cycle in proportion to the engine speed can only provide adequate control under normal circumstances, but it cannot help Transient engine operation. Therefore, according to the control method of the present invention, the control unit 13 is also sensed when the accelerator is turned on quickly. At this time, the load is shortened to a specified engine speed. In order to ensure that the amount of fuel supplied to the engine is not exceeded. And it can be guaranteed that the amount of lubricant supplied is suitable for the actual operation of the engine 2. Work-depending on ^ Of course, the degree of control described is actually based on the actual requirements of the engine in II. But it must be understood that: due to the mentioned system and the method of using the two-stroke engine, when the fuel supply and The length of time the control valve is in the flow state.

The lubricating oil pump 3 is composed of a reciprocating plunger driven by an engine, and has a structure in which the reciprocating stroke of the plunger is adjusted according to the opening of the throttle valve. The three-way solenoid valve actuates the control valve 8o through a lubricating oil return passage 7 to communicate with the lubricating oil tank 5, and at the same time communicates with the engine 2 through a lubricating oil supply passage 4. Furthermore, the three-way control valve 8 is controlled by a pseudo spiral tube, and is switched between the supply and return channels 4, 7. Solenoid 0N / 0FF action (on / off action).

The control unit 13 includes a calculation means 17 for calculating the engine rotation speed , A computer 18, a counter 19 and an interrupt time setting means As a main component, the calculation means 17 used to calculate the engine rotation speed has a structure, such as used to calculate the engine rotation speed even when the engine is running and outputs the rotation speed response signal to the computer 18.

Description of invention () While the plug can still perform at least one reciprocating motion, a time period is used as the OFF period of the control valve. In this embodiment, in order to perform fuel supply control, the three-way electromagnetically actuated control valve The OFF period remains the same, on the other hand, the ON period is made variable. In other words, the period of the re-excitation flow state remains unchanged, while the excitation non-flow state is made variable. ON The period does not need to have a minimum value, and so is the OFF period. When the OFF period of the helical coil 12 is determined, the aforementioned OFF period can be adjusted to change according to the engine operating conditions. For example, the OFF cycle can be changed for engine running conditions, such as idling, medium-speed operation, and high-speed lotus rotation. In this case, the OFF period can be maintained unchanged, or, preferably, it can be changed stepwise in a stepwise manner, but it can be changed at a fixed rate according to the engine rotation speed. Even in this case, the ON cycle (the non-flow state of the control valve 8) often changes with the engine operating conditions. Moreover, as soon as the operating conditions, such as the engine rotation speed of the engine, change, the mission control valve changes in accordance with the load ratio suitable for the changed lotus rotation conditions. As a counter of a time calculation means 19, the counter is used to calculate the time lapse after the supply of lubricating oil to the engine 2 is started for each task control period while the three-way electromagnetic actuation control valve 8 is switched ON or OFF. The setting means 20 for determining the return interruption period has a structure for continuously comparing the time lapse calculated by the counter with the current ideal target task control period obtained from the computer 18. Then, when the time lapse corresponds to the task control cycle, the control valve 8 is switched off by the aforementioned return interruption period setting means 20, and the next task control cycle is continued. In other words, compare the end time of the lubricating oil return cycle (0N cycle) with a load that is less than the standard SH SH Standard (CNS) T 4 specification (210x297 g) and -20- 81. 6.

Λ 6 Π G V. Description of the invention () (This load ratio can obtain the optimal amount of lubricating oil suitable for the instantaneous engine operation), and when it meets the load ratio, the task control cycle ends. Referring to Figs. 6-8, the method of properly lubricating the engine 2 and the operation of the fuel supply system 1 according to this embodiment will be described below. As can be seen from Fig. 6, when the main switch 14 is turned ON, the control unit 13 starts at step P: first. After the engine is started, the means 17 for calculating the engine rotation speed of the control unit 13 calculates the aforementioned speed in step 2 and outputs the aforementioned speed to the computer 18. Immediately after the engine is started, since the three-way actuation control valve 8 is in a flow state (OFF state), the lubricating oil sent from the oil pump 3 is supplied to the engine 2. When fuel is supplied, the counter starts counting time. After a predetermined period of time has elapsed from the start of the supply of lubricating oil to the engine 2, the control valve 8 is excited by turning on the computer 18 to switch from the flow state to the non-flow state to the ON state. Then, the lubricating oil is led back to the oil return channel 7. Secondly, the steps? 3. The computer reads out a load ratio corresponding to the detected engine rotation speed from the plaque, and calculates the task control cycle of Xing Shi in step P4. The duty cycle of the control valve 8 divided by the constant of the load ratio is used to determine the task control cycle. This means that when the engine 2 is running, the computer 18 continues to calculate the task control cycle. Then in step P5, the setting means 20 for setting the interruption period of the oil return sets the aforementioned interruption period. At that time, compared with the task control period obtained in step 4, the elapsed time calculated by the counter from the start of the lubricating oil supply, and when the elapsed time reaches the task control period, proceed to step 6. Convert the three-way actuation control valve 8 Into its flow state (OFF state). When the time period has not reached the task cycle, return to step 1 from step 5 and repeat the above operation (please pay attention to the back and forth of the wooden page).

Λ 6 Π G Central Ministry of Economic Affairs and the cooperation between industrial and consumer enterprises Du Yin 51 V. Description of the invention () When the control valve 8 is turned OFF in step 6, one cycle of task control ends, and the process returns to step 1. The counter 19 restarts when the control valve 8 is turned OFF. The operation of the control valve 8 in the transient operation will be described below with reference to FIG. 11. That is, the case of the engine rotation speed rising from a low speed or falling from a high speed will be described. When the engine 2 is in the idling state shown in A in Figure 7 (a), the load ratio of the self-control unit 13 reads the load ratio, for example, 15%. As shown in Figure 7 (b), the load ratio generally changes according to the change of the engine rotation speed. When the throttle valve of the engine is fully opened, it reaches 100%. The task control period during idling becomes U as shown in Figure 7 (c). The task control period U is taken as the time before the solid line T (increased display of passage of time) reaches the task control period derived from the load ratio (the height of the supply start time line shown by the broken line in Fig. 7c). This means that the return interruption period when the control valve 8 is switched from the 0H state to the OFF state is taken as the period when the fuel supply start period from the task control period coincides with the ideal control period in accordance with the engine rotation speed. The two-dot chain line in Figure 7 (c) pseudo-one shows the line of the engine's fuel supply interruption period, when the control valve 8 is twisted open to interrupt the delivery of lubricating oil. The interruption timeline for supplying fuel to the engine and the start timeline for supplying fuel to the engine (as indicated by the dashed line) are determined from the engine rotation speed according to the load ratio shown in Figure 8. Taking the height of the timeline in Figure 8 as the task control period of the engine's turning speed, it indicates that the engine's fuel supply starts. In this embodiment, the OFF time of the control valve 8 is assumed to be constant. The time line for interrupting the fuel supply is parallel to the horizontal axis. (Please note first-back to the total 傀 项 Piao Jieji Mu Ting) The standard specifications of the siege of this paper is 22-81. 6. 10,000¾ (II) ^; 〇ib〇 ^ λ ί) _Π6_ 5 Description of the invention () Furthermore, when the engine rotation speed rises the entire curve portion B as shown in Figure 7 (a), the demand for engine oil of engine 2 increases, and the load ratio also increases. When the duty ratio increases, the task control period shortens as the engine rotation speed increases; because the OFF period does not change, and the ON supply start time line slopes downward to the right, as shown in Figure 7 (c). At this time, it is used to break the heading period during the reflux. Moreover, when the engine 2 assumes the high speed of the gold open throttle as shown in the entire curve portion D of FIG. 7 (a), since the duty ratio becomes 100%, the 0N cycle becomes zero and task control The period becomes equal to the OFF period. The task control period at this time is pseudo-marked with t3 in the 7c plaque. Therefore, the control valve 8 is in a flowing state (0F state), so that the lubricant is supplied to the engine 2 again. When the engine rotation speed begins to decrease as shown in Fig. 7 (a) E, the load ratio also decreases, and the task control period is extended when the engine rotation speed is reduced. Here, the supply start time line in Figure 7 (c) is inclined upward to the right, and becomes parallel to the horizontal axis after the engine rotation speed becomes constant. The time indicated by G is taken as the backflow interruption period of this embodiment. At this time, the time elapsed from the start of the OFF state (the flow state of the control valve 8) to the task control period. Thus, the task control period becomes U. The Ministry of Economic Affairs, Ministry of Economic Affairs, Central Bureau of Industry and Commerce, 1V cooperation, Du Yin 51 (please note first and foremost the matters to be noted), the hard-working system 2 of the two-stroke engine 2 interrupts the return passage ( During this period, the lubricating oil is guided to the lubricating oil return channel 7) and the load ratio (the ratio of the lubricating oil supply is the most suitable for instant engine operation), and the task control period is determined when the load ratio is met. Change, the task control period changes with the load ratio suitable for the instantaneous engine lotus rotation. As shown in Figure 4, it is used to supply lubrication.

Furthermore, before the solenoid coil 12 is re-excited, this supply start timing means 27 resets the cumulative trigger number in the counter 22 to zero. That is, as soon as the lubricant left in the engine is exhausted, the lubricant is re-supplied to the engine 2 side. Moreover, the supply period setting means 27 has a structure for determining whether the lubricating oil interruption time (the time elapsed after the supply interruption means starts to operate) is longer or shorter than the set time.

Description of invention () The oil pump 3 also starts to move with the engine 2 to deliver lubricant to Three-way solenoid valve 8. At this time, since the cumulative trigger number of the timer 22 is less than the set value and the coil coil 12 of the three-way solenoid valve 8 is not excited, the lubricant is supplied to the engine 12 from the three-way solenoid valve 8. When the lubricating oil is supplied to the engine 2, the supply amount calculation means 24 calculates the supply amount of the lubricant. When the cumulative trigger number reaches a set value (at step Ps), the three-way solenoid valve 8 is excited by the supply interruption means 23, so the lubricant oil is not supplied to the engine 2 and returns to the lubricant tank 5. When the supply interruption means is activated, the lubricant consumption is calculated by the consumption calculation means (at step 8), and the lubricant consumption is subtracted from the lubricant supply to calculate the residual amount of lubricant. Yu Bu SEPi. As with the above residual amount calculation, the deduction result will be integrated. Then, in step i.e. The consumption calculation method 25 determines whether the interruption time of the lubricating oil is longer or shorter than the set time; and if the lubricating oil interruption time is shorter than the set time and normal. Go to step 11 to determine whether the integral value is zero or negative, or neither. If zero or negative is determined, the cumulative trigger number of the timer 22 is then reset to zero (at step 13), and the solenoid coil 12 of the three-way solenoid valve 8 is re-magnetized (at step 14). By this operation, lubricating oil is supplied from the three-way solenoid valve 8 side to the engine 2 side. The lubricating oil supply system 1 according to the present invention performs a series of the above-mentioned actions as a cycle; then, after returning to the lubricating oil supply state (at step 14). Return to step P 2 to perform the second cycle of operation. If it is determined in step 11 that the lubricating oil interruption time is longer than the set time, then proceed to step P3, and the excitation of the spiral coil 12 is irrespective of the integration result.

Figure 12 shows an example in which the engine 2 accelerates rapidly from a low-speed operation state to a high-speed operation state and then returns to a low-speed operation state. When the engine 2 is operated as described above, the amount of lubricating oil required by the engine 2 changes with the rotation speed of the engine, and the time and the amount of lubricating oil delivered from the lubricant pump 3 also change with the rotation speed of the engine, as described in section 12 (b ) As shown in the figure. Furthermore, when the three-way solenoid valve 8 is switched, the time period during which the solenoid coil 12 is not energized (T in Figure 12) becomes constant; the oil return time when the engine speed becomes higher It becomes shorter, and the amount of lubricating oil becomes larger with the speed of the engine's turning speed, as shown in Figure 12 (d). During the cycle of supplying lubricating oil, as shown in the shaded kneading section, the display control operation follows.

It can be seen from Figure 12 (f). After the remaining amount is exhausted, re-supply oil to the engine. Here, although the above embodiment is composed of a structure in which the lubricating oil supply time of the engine is kept constant and the lubricating oil return time is made variable, the present invention is not limited to this structure, and the generality of the present invention may be It is configured to change the supply time of lubricating oil to the engine.

Due to a supply calculation method (calculating the supply of lubricating oil to the engine side from the engine rotation speed), a consumption calculation method (automatic engine rotation speed after switching the switching valve to the return channel), throttling Read the time setting method (when the lubricant supply and lubricant consumption are consistent with each other, reverse the switching valve from the return channel to the supply channel), set the oil return interruption period, so the lubricant consumption of the engine side is supplied from the switching valve After the exhaustion, re-supply lubricant to the engine. Therefore, lubricating oil can always be supplied in an appropriate supply, and white smoke can be prevented from being generated from the engine. The control unit 13 for controlling the three-way solenoid valve 8 is configured to change the lubricating oil return time of the three-way solenoid valve 8. The control unit 13 is provided with a supply amount calculation means, a consumption amount calculation means, and a supply start time setting means so that the three-way solenoid valve is switched when the residual lubricating oil is exhausted. When the lubricant supplied to the engine from the three-way solenoid valve is exhausted, supply lubricant to the engine 2 side again. In another modification of the lubricating oil supply system, the lubricating oil supply cycle remains unchanged. Based on a predetermined load ratio (this load ratio can obtain a suitable amount of lubrication for the current running conditions) and the current engine rotation speed, the lubricating oil supply cycle becomes longer, thereby reducing the delay of the switching valve Forging; on the other hand, make the supply cycle of Jian Lu oil shorter, thereby shortening the control cycle, and changing the supply of lubricating oil with the more swift changes in the engine's operating conditions. Therefore, it can reduce the delay of the switching valve operation.

The symbol 13 is a pseudo-control unit for controlling the operation of the three-way solenoid valve 8. The control unit 13 is configured as Used to switch the ON and OFF of the solenoid coil 12 so that the supply and return states of the lubricant can be repeated to control the amount of lubricant supplied to the engine 2. The OFF period of the solenoid coil 12 is at high engine speed and When the amount of lubricating oil supplied by the engine is less than in other occasions, it becomes shorter; and its 0N cycle is changed according to the operation of the engine by the method described later. The control unit 13 is pseudo-connected to a battery through a main switch 14 15, same It is connected to the ignition system of engine 2 to calculate the engine rotation speed, and is also connected to the throttle valve system to detect the opening of the throttle valve.

The timer 22 has a structure like to count the starting time immediately after the engine is started; Trigger time (for example, 80ms) to generate trigger multiples; and cumulative trigger number. Symbol 23 is a supply interruption means for exciting the solenoid coil 12 of the three-way solenoid valve 8 so as to guide the flow of lubricating oil to the return passage. This supply interruption means 23 has a structure for exciting the solenoid coil 12 when the accumulated trigger number of the timer 22 reaches a set value. That is, before the supply interruption valve 23 is determined by the supply interruption means 23 (determined by the load diagram shown in Fig. 14, engine rotation speed, throttle opening, etc.), lubricating oil is supplied to the engine. That is, even if the throttle valve is widely opened, the supply of lubricating oil is still low before the engine speed reaches a certain high speed. Therefore, when the engine return speed is in the low to medium range and the throttle opening is large, the amount of oil supply becomes smaller, but the amount of lubricating oil also becomes less when it escapes. Figure 15 also shows the consumption or demand of lubricating oil in accordance with the operation of the engine. Here, the load ratio diagram in Fig. 4 will be described in detail. The load ratio diagram is constructed such that when the engine rotation speed or throttle opening reaches their maximum value, the load ratio can reach its highest value of 100%. Load ratio (please first read the back and note #Dangjimu R) 5fc scale of this paper is used in the SB home brown standard (CNS)> T4 specifications (2 丨 0x297 public release) -32- 81.6. 10,0Q0? ft (II) Standards issued by the Ministry of Economic Affairs and printed by the "Cooperative" V. The description of the invention () The engine rotation speed or throttle valve opening to 100% is provided with a certain rotation speed range Or the opening range, and the area where the duty ratio becomes 100% (the highest part in the 14th circle) becomes flat. In addition, the load ratio of the low engine rotation speed is set to the lowest value to obtain the required amount of lubricating oil supply for the engine 2; then the engine rotation speed or throttle opening degree is provided with a certain degree of rotation speed or The range of the throttle valve, thereby flattening the area where the duty ratio becomes the lowest. Although the area where the load ratio becomes 100% or the lowest is flat, the amount of oil supplied by the oil pump is proportional to the engine rotation speed because the oil pump is driven by the engine, so the amount of oil supplied can vary, as shown in Figure 15. As shown. Since the load ratio chart with the area where the load ratio becomes 100% or the lowest is compiled, it can be controlled separately when the load ratio in accordance with the engine operating conditions takes a value between 100% and the lowest. That is, since the load ratio that can be included in the required engine operation condition can be made larger, the lubricating oil supply amount can be set with high accuracy according to each engine operation condition. Symbol 24 is a pseudo-supply gauge method for calculating the amount of lubricant supplied to the engine 2 side. This supply amount calculation means 24 has a structure that calculates the supply amount of lubricating oil based on the engine return speed when the solenoid coil 12 of the three-way solenoid valve 8 is in the OFF state. This lubricating oil supply amount is obtained by multiplying the engine rotation speed by the delivery of the oil pump 3 for each revolution of the engine during the lubricant supply cycle. Symbol 25 is a consumption calculation method for calculating the amount of lubricating oil consumed in the engine 2. This consumption calculation method 25 has a structure, which is based on (please read first-note on the back and write wooden pages on the paper side of the paper).

Description of invention () After the start of the supply interruption means 23, it is not in accordance with the engine transfer The oil consumption per unit time of the speed throttle opening and the elapsed time. When supplying oil to the engine 2 side, calculate the amount of oil consumed. Use the data stored in the 15th consumption chart in advance Value. As the consumption of lubricating oil per unit time obtained from the engine rotation speed and throttle opening. Symbol 27 is a residual detection method, which is false when the lubricant supplied to the engine 2 is exhausted. The coil coil 12 of the three-way solenoid valve 8 and the one that guides the flow of lubricating oil to the supply passage 4a. The residual amount detection means 27 has a structure for lubricating calculated from the supply gauge means 24 Oil supply minus lubricant consumption calculated by consumption calculation means 25 The difference obtained by the integration; and when the resulting value becomes zero or negative, the solenoid coil 12 of the three-way solenoid valve 8 is re-excited. Furthermore, this residual amount detection means 27 is before the solenoid coil 12 is re-excited , Set the cumulative number of timers in the timer 22. The consumption of lubricating oil on the engine side 2 is re-supplied as soon as the amount of lubricating oil is consumed on the engine side 2. The residual amount detection means 27 has a structure . After the result of the point deduction, determine whether the lubricating oil return cycle (the time elapsed after the start of the supply interruption means 23) is longer or shorter than the predetermined time; The magnetic coil 12 is re-excited to prevent the lubricating oil return cycle from becoming longer for some reason. Next, according to FIGS. 16 and 17, the operation of the lubricating oil supply system 1 of the two-stroke engine constructed as described above will be described.

At this time, the accumulation of timer 22 is triggered The number resets to zero. When the engine 2 is started, the devices of the engine control system such as the ignition unit 161 are controlled (at step 3). As the engine starts, the timer 22 starts timing and outputs a trigger multiple (at step Ρ *); Then, the trigger number is added by 1 (at step Pa). In step Ps, the supply interruption means 23 is set-the lubricating oil supply cycle (the cumulative trigger number setting value), and then determines whether the cumulative ® number of hits has reached Set value (in step P7). That is, the timer 22 continues to accumulate the number of triggers until the lubricating oil supply period set by the supply interruption means 23 is reached. The lubricating oil pump 3 also starts to operate when returning to the engine 2 to deliver the lubricating oil to Three-way solenoid valve 8. When the number of triggers by the timer is less than the set value, the solenoid coil of the solenoid valve 8 is magnetic, so the lubricating oil is sent from the three-way solenoid valve 8 to the engine 2. When the lubrication When oil is supplied to the engine 2 side, The supply amount calculation means 24 calculates the lubricant supply amount. Here, the setting procedure of the lubricant supply period (the set value of the cumulative trigger number) is explained with reference to FIG. 17. In step Ps, the supply interruption means 23 reads the engine rotation speed R ; And in step Si, let in the throttle opening; then, in step, read out the load ratio shown in Figure 14, the load ratio D according to the engine back speed and the throttle suitable for the current engine operation Valve opening degree. Next, in step Sa, the supply interruption means 23 determines whether the above-mentioned load ratio I) is greater than a predetermined value A. When the duty ratio D is greater than A, that is, when the lubricating oil demand of the engine 2 is large, enter step% to set the supply cycle such as T i; then in step 6.

When the duty ratio D is less than the predetermined value A (at step S (S3), that is, the lubricating oil requirement of the engine 2 is small, the supply interruption interruption means 23 determines that the engine rotation speed R is higher than the predetermined speed B (at step Ss) When the engine rotation speed is not higher than a predetermined speed B, enter the step to set the lube oil supply cycle such as T »; then, it will be used to set the output signal such as Ta to output the timer 22 (at step Se). The chief decides the engine When the rotation speed A is higher than the speed B (at step SE), go to step Ss to set the lubricating oil supply cycle such as T3; then, use the output multiplier output timer 22 such as T3 (at step S). ).

Invention description) When the number of accumulated triggers reaches the set value (in step p7), the spiral of the three-way solenoid valve 8 The tube coil 12 is excited by the supply interruption means 23 (at step 8), so that there is no lubricating oil To the engine 2 side, the lubricating oil is returned to the lubricating oil tank 5 of the wave I. When the supply interruption means 23 is activated and the lubricating oil starts to return to the lubricating oil tank 5, the consumption metering means 25 calculates the lubricating oil consumption (in step P,) Then, the lubricant consumption is subtracted from the lubricant supply to calculate the residual amount of lubricant (at step P *.), And at the same time as the calculation of the residual amount, the result of subtraction is subtracted (at step P ^). After the integral is subtracted, the consumption calculation means 25 determines whether the lubricating oil return cycle is longer or shorter than the set time (at step P13), and if the lubricating oil return cycle is shorter than the predetermined maximum control cycle and normal, Then go to step P13 to determine whether the integral value is equal to zero or negative. When it is zero or negative, the cumulative trigger number is reset to zero (at step P14), and then the solenoid coil 12 of the three-way solenoid valve 8 is excited (at step Pβ). By this operation, lubricating oil is again supplied from the three-way solenoid valve 8 to the engine 2 side. The lubricating oil system 19 according to the present invention performs a series of the above operations as a cycle, and then, after switching to the lubricating oil supply state (at step P1 B), returns to step P 2 to start the next cycle. If it is determined that the lubrication return period is longer than the longest control period, step Pm is entered. The excitation of the solenoid coil 12 is immediately interrupted. If the sub-point value is not equal to zero or negative, return to step P2. The operation of the lubricating oil supply system 1 according to the present invention is shown in paragraphs 18 (a) to 13 (f).

Λ (i It G Fifth, the description of the invention) The situation where the speed acceleration is in the high-speed lotus rotation state, and then returns to the low-speed operation state. When the lotus rotation engine 2 is as described above, the lubricant demand of the engine 2 changes according to the engine rotation speed, As shown in the 18th (a) circle; and the time and number of delivery from the lubricating oil pump also change according to the engine rotation speed, as shown in the 18th (b) plaque. Also, when the three-way solenoid valve is opened, the spiral The period during which the tube coil is not magnetized (lube oil supply cycle) varies according to the engine operating conditions, such as T3, as shown in Figure 18 (e); and the lubricating oil supply is increased according to the engine rotation speed, as shown in 18 (d). As shown in the figure. In Figure 18 (d), the period of the lubricant supply period is pseudo-hatched. The dagger ~ (: 7 indicates the control operation cycle. The lubricant supply period is or the control time chart of Ta is pseudo-as in the 19th. (a) as shown in the figure; and the control time chart for the lube oil supply cycle of T3 is shown in line 19 (b). In these figures, the "dummy" and "pseudo" indicate the delay in the operation of the three-way solenoid valve 8 when it is opened and closed. The Ministry of Economic Affairs is centrally accurate, ^ Α 工 价 价 合作社 印 ft, 14 (Please read the Regarding Xiang Xiang (Sun Xun and Gu Mu'an) as shown in Figure 19U). Set a longer lube oil supply cycle to reduce the delay of operation delay and improve the accuracy of bosu supply. In addition, the setting is relatively short Lubricating oil supply cycle is like Τ3; as the control cycle is shortened and the return cycle of lubricating oil when the three-way solenoid valve is in the ON state becomes shorter as shown in Figure 19 (b), it is possible to improve the lubrication of changes in engine operating conditions The tightness of the oil supply. Well, even if the operation of the engine 2 changes suddenly, the lubricating oil requirement of the engine 2 suddenly increases. As a result, the supplied oil is consumed in advance due to the high engine rotation speed. A control week will come and re-supply lubricating oil.

Description of invention () In figure 18 (e), the integral value of lubricant supply is shown in A; the integral value of lubricant consumption is falsely shown Yu B; and from lubricant supply minus lubricant consumption The obtained value (residual amount of lubricating oil) is shown in Figure 18 (f). It can be seen from Figure 18 (f). After the remaining amount is consumed, lubricating oil is re-supplied. Therefore, due to the lubricating oil supply system 1 of the present invention , When the return of lubricating oil is interrupted, the operating condition of the engine changes, and after the lubricating oil supplied to the engine 2 side from the three-way solenoid valve 8 is exhausted, lubricating oil is re-supplied to the engine. When a small amount is set and the engine rotation speed is greater than the predetermined speed, since the lube oil supply cycle is set to be shorter than 13 in other occasions, the control cycle becomes shorter, and the lube oil supply volume is better followed It changes with the change of engine operation. In addition to the above control cycle becomes shorter. Since the lubrication oil supply cycle is set to a longer ^ and * ^, and the three-way solenoid valve 8 operation delay delay can be reduced. Therefore, the supply accuracy of the lubricant becomes For higher. The load ratio used to obtain the supply of lubricating oil is not limited to the 14th employment I, but can also be constructed as shown in Figure 20. Another embodiment using the load ratio shown in Fig. 20 will be described later. Fig. 20 is a graph showing another embodiment of the load ratio. Figure 21 is a graph showing the amount of lubricant supplied when using the load ratio of Figure 20. Fig. 22 is a pseudo-flow chart showing the setting operation of the lubricating oil supply cycle when the load ratio in Fig. 20 is used. Components that are the same as or correspond to those in FIGS. 13 to 19 are given the same symbols as in FIGS. 13 to 19, and their further description is omitted.

The load ratio chart in Figure 20 has a field (shown in Figure 20 T4); the load ratio, even if the operating speed is lower than B It also becomes larger than Α. When the engine rotation speed and throttle opening increase, the amount of lubricating oil supplied using this load ratio becomes larger, as shown in Figure 21. The flow chart in Figure 22 is used to set the lubricating oil supply cycle. The composition of the flowchart shown in FIG. 22 is pseudo-adding an engine rotation speed determination process S »: in step 33 shown in FIG. 17 and, so that when the load ratio D is greater than / \ and the engine rotation speed When R is higher than the rotation speed B, proceed to step S * to set the lube oil supply cycle such as T; and when the whistle engine rotation speed R is equal to or lower than the rotation speed B go to step S12 to set the lube oil supply cycle; Then, in step Si3, a multiple is output to the timer 22 to set the lubricating oil supply cycle such as T *. The period T «is set to be longer like ^ or · ^. The above structure can still obtain the same effect as the previous embodiment. Although the lubricating oil control cycle is controlled by the above embodiment, the present invention does not limit this structure. The system of the present invention can be configured to control the lubricating oil supply cycle to the engine 2 side. In this case, the ON time of the three-way solenoid valve 8 varies according to the engine operating conditions, and the OFF time is controlled by the control unit 13. Furthermore, although the above embodiment uses a two-stroke engine as the control purpose, the present invention can be applied to a four-stroke engine having a structure, such as injecting a mixture of air and fuel into the combustion chamber. That is: the present invention can be applied to lubricating oil supply system for spraying lubricating oil to the sliding part of the engine. Since the present invention can be applied to engines, it can be applied to locomotives, electric vehicles, and working machines such as outboard horses, lawn mowers, golf carts, and the like.

Description of the invention () Furthermore, it is also possible to provide a load ratio as shown in Figure 14 or Group 20 of a field, here In the field, when the engine rotation speed becomes extremely low (zero or below idling), the duty ratio becomes 100%. In other words, a unified structure of the lubricating oil supply bar can also be provided so that the engine rotation speed becomes low (zero or below idling) ) To cut off the drive number of the three-way solenoid valve 8. Because of this structure, the power supply to the three-way solenoid valve 8 can be interrupted before the engine is started, and the power consumption of the solenoid coil 12 of the three-way solenoid valve 8 can be suppressed. Furthermore, according to the present invention, the lubricating oil supply system 1 for a two-stroke engine can also provide a device to open the three-way solenoid valve only 8 times when starting the engine 2 with a surge starter. When this is provided For this type of device, the three-way solenoid valve 8 starts to open when the main switch 14 is turned on for the first rush In addition, when the engine 2 is started after neglecting the lotus rotation for a long time, the corrected lubricating oil return cycle can be longer than the return cycle determined by the system 1 of the present invention immediately after the engine is started, until the engine rotation speed exceeds the predetermined speed or until The predetermined time has passed; I think this is because some lubricating oil has accumulated in the engine. Furthermore, the system 1 of the present invention can also be configured so that the control of the present invention is not started immediately after the engine is started, until the engine bounce speed exceeds a predetermined The speed or until a predetermined time elapses. As mentioned above, since the lubricating oil supply bar of this embodiment is provided with a supply start time setting means when the lubricating oil supply cycle is kept constant. The lubricating oil is determined according to the current engine operating conditions Return to the period of interruption, so when the engine operating conditions change, the amount of lubricating oil supply becomes suitable for the current engine operating conditions. Therefore, it can be increased. The accuracy of the oil supply.
