Description

The present invention relates to a method for proactive management of alerts and alarms, of the internal combustion heat engine of the transport vehicle and on a fixed frame. It is an intelligent system that automatically watches, day and night 24/7 and in real time, on the health of the engine of a moving vehicle to allow it to solve its 10 reversible problems (indicated by orange or yellow alerts). ) and to quarantine it in order to protect it from its irreversible problems (indicated by the red alarms). The internal combustion engine is a type of engine in which the thermal energy given off by the combustion of a fluid is converted into mechanical energy inside the engine. This is the group of organs that provide the mechanical energy necessary for the operation of the vehicle. 15 Just as body fluids (water and blood) are vital in humans, fluids (engine oil, coolant and brake fluid) are also vital for the engine. These engines are mainly used for the transmission and propulsion of transport vehicles (motorcycles, automobiles, trucks, boats and airplanes) and for fixed frames (generators).

The method comprises three (03) main components: three (03) individual reservoirs or one (01) multi-compartmental reservoir of reserve fluid provided with level probes, one (01) control panel provided with replicas of the indicator lights and vehicle dashboard warning and alarm sounds; new dual warning and alarm lights for reserve fluid level probes, one (01) test button for simulation, one (01) four (04) position switch pushbutton allowing interaction between the man and process by mechanical action and two (02) proactive, independently operating circuits each playing a specific role. Each circuit is connected directly to sensors permanently probing certain specific engine components and instantly indicating their status for their visualizations through, on the one hand, the indicator lights on the dashboard and through, on the other hand, their cues on the control board.

The novelty consists in capturing, transforming to redirect the characteristic electrical impulse, positive (12 / 24v) or negative (-) towards the replicas of the control panel, which generates a change of status to automatically activate and / or deactivate the proactive circuits . The control panel has a digital screen and a sound unit and is used to process, broadcast error codes, visualize the statuses and operating processes and the information transmitted by the circuits and avoid tampering with the integrity of the panel. on board. With regard to proactive circuits, the first role is, on the one hand, to automatically inject reserve engine oil into the engine lubrication circuit, reserve coolant into the engine cooling circuit and reserve brake fluid in the vehicle's braking circuit, during an orange alert and on the other hand, thanks to the push button to have 40 injected manually, during a check revealing the low level of one of the fluids; the second, on the one hand, to cut the engine automatically in the event of a red alarm and prevent it from being restarted as long as the problem remains unresolved, and on the other hand, to cut it manually using the push button to serve as the main circuit breaker.

Each compartment is obligatorily marked and contains a specific reserve fluid (engine oil, coolant or brake fluid) in order to avoid confusion and / or mixing of fluid when it is injected into the offending circuit.

The entire process is used for proactive management of the lubrication and / or cooling systems of internal combustion engines and / or the vehicle's braking system.

In place of the driver, the innovative method guarantees, among other things, the correct level of fluids 10 thus ensuring good lubrication and a good temperature for the proper functioning of the components of said engine. It thus protects the engine from deterioration (engine overheating) or premature destruction (engine clamping). It prevents the driver from using a vehicle if the required brake oil level is too low, thus preventing traffic accidents.

To do this, in the event of an alert warning the driver of a problem with a low level of a motor fluid, it is no longer necessary to wait for the next vehicle stop to make the additions. In the event of an alarm, warning him of a danger to the engine, it is no longer necessary for the driver to panic to urgently shut down the engine, it will be done automatically and gradually and thunderously to avoid accidents.

In the state of the art, a transport vehicle engine is already equipped with several pressure switches, probing its key components passively to diagnose them and automatically transmit their statuses to its dashboard directly or via a computer, which allows the driver to visualize in real time, the indicator lights, signaling indicators (green), alerts (orange / yellow) and alarms (red). Indeed, in addition to fuel, a transport vehicle engine needs different fluids that allow it to operate optimally. A slight consumption of fluids is necessary and is manifested by its disappearance inside the engine when it is running. The right level is essential to reduce friction, reduce wear on mechanical parts and maintain the right temperature. Conversely, excessive consumption or a leak can suddenly lead to a drop in level and especially a lack of fluid which can very quickly damage or completely destroy the engine. When it is lacking, the consequences can be varied ... and very often harmful to the mechanics. We therefore avoid a lot of trouble, by constantly viewing the status of their indicator lights on the dashboard and by manually and regularly gauging their levels. The sensors passively watch over the health of the engine to display its operating status at all times. Passive activation of the too low engine oil warning lights, too low coolant level warning light and the too low brake fluid warning light are additional warning lights. A diagnosis is recommended the next time the vehicle is stopped in order to top up the level of the fluid alerted. Passive activation of warning lights for insufficient engine oil pressure, too high engine oil temperature and too high coolant temperature, mean an urgent and immediate shutdown of the vehicle. Their classification and meaning according to their colors and priority levels is as follows:

Car warning lights, green / blue signaling.

They indicate the status of an accessory activated or deactivated by the driver (lights). Only the glow plug preheating indicator light does not respond to this coloration. It is represented by a small orange spring which must be waited for extinction before starting a diesel engine. The other 5 warning lights respond to the activation of the lights, the demisting of the rear screen or the handbrake engaged.

Car warning lights, orange / yellow warning.

They are displayed in orange or yellow and warn the driver of a mechanical or electronic problem (breakdown or malfunction) without prompting him to stop. It should be looked at later. It includes the warning of engine oil level, coolant level, a malfunction of the airbag or the braking system, a problem of traction control, pollution control, power steering or lighting and the presence of water in the diesel filter. The best known is the fuel level which generally activates at 10% of tank capacity.

Appearance of the orange or yellow oil level warning light.

The engine oil pressure light is easily identifiable thanks to its orange pictogram representing an oil can with a falling drop, that is to say a bottle with a neck similar to a small watering can on a wave represented below.

Engine Oil: As we all know, there is a bunch of metal parts in constant friction in the engine. Engine oil will therefore lubricate sensitive areas to prevent seizure by reducing friction and wear of mechanical parts. Indeed, without oil it only takes a few seconds to destroy an engine. The metal parts rubbing against each other cause a strong heat (friction) which will eventually deform them (the metal melts). This requires constantly having a suitable level of oil and managing its use. The present proactive method of automatic fluid injection allows this role to be constantly fulfilled, depending on the scenario present, hence its usefulness.

Low engine oil orange warning scenario.

In a moving vehicle, the orange engine oil level warning light comes on, it has just received an orange low level alert via its oil level sensor submerged in the crankcase, the level is at minimum level. Instantly, a minimum level pulse is transmitted directly or via the computer by said probe which activates said orange low oil level warning light, on the instrument panel and on its replica of the new control panel, which in its turn. tower automatically activates the solenoid valve-injector-venturi of the proactive engine oil circuit in order to allow it to draw off a quantity of oil from its reserve tank and to inject it into said crankcase or elsewhere in the lubrication circuit, to complete the level. Once the oil level in the crankcase has reached the maximum level, said venturi stops the injection to prevent overfilling. At this moment, a second maximum level pulse is transmitted directly or to the computer by said sensor which deactivates the orange oil level warning light (extinction) on the dashboard and on the control panel. The low level problem in the crankcase is then solved.

Appearance of the orange or yellow coolant level warning light.

It can be in the form of the symbol of an orange / yellow thermometer, with 2 waves represented in the lower part symbolizing the coolant. It can also be in the form of a pictogram representing the upper part of a radiator with its cap with waves represented below.

Cooling liquid: The cooling system needs a specific liquid to cool the engine and evacuate the calories emitted. It is a fluid, mainly composed of treated water and antifreeze, that keeps the engine at its ideal operating temperature. In a closed circuit, it is continuously cooled by the radiator before it passes through the engine. Without coolant, the engine would overheat at high speed. The coolant allows the engine to run at a constant temperature. Its level must therefore be checked frequently. For example, the excessive consumption of coolant which may activate the amber low level warning light on the instrument panel may be due to the contents or the airtight cap of the expansion tank in the state. the cooling system hoses, the condition of the cooling radiator and the quality of the engine oil.

Scenario of an orange warning of an engine coolant level too low.

On board a moving vehicle, the orange engine coolant level warning light comes on, it has just received an orange low level alert via its coolant level sensor submerged in the vessel. expansion; the level is at the minimum. Simultaneously, a first minimum level pulse is transmitted directly or to the computer by said probe which activates said orange coolant level warning light, on the instrument panel and on its replica of the new control panel, which in turn also activates the solenoid valve-injector-venturi of the proactive coolant circuit in order to allow it to automatically release, from its make-up tank a quantity of coolant directly into said vessel or elsewhere in the cooling circuit , to complete the level. Once the level of coolant in the vessel has reached the maximum level, a second maximum level pulse is transmitted directly or to the computer by said probe which deactivates said orange coolant level warning light on the instrument panel and on the new control panel which in turn deactivates the coolant makeup solenoid-injector-venturi. The low level problem in the expansion tank is then resolved.

The coolant injector fixed in the expansion tank, will be positioned exactly like the main inlet hose coming from the radiator which is located below the level of the liquid, so that there is no introduction air in the circuit when the liquid cools down and returns to the engine. This position will automatically inject the high pressure, bubble-free coolant directly into the expansion tank, to replenish it with coolant and resolve the reported low coolant problem.

Appearance of the red brake fluid level warning light.

It is imperative to identify the brake fluid warning light. It is often a red or yellow pictogram representing a circle surrounded by two arcs of a circle, associated with an exclamation mark.

Brake fluid: When the brake pedal is depressed, pressurized fluid is sent to the various components of the circuit. Under this pressure, the brake pads are clamped against the disc, which ensures the braking of the wheels. The brake fluid being at the heart of the mechanism, its absence therefore makes any braking impossible.

Red brake fluid level warning scenario.

On board a moving vehicle, the red brake fluid level warning light comes on, it has just received a red low level alert via its brake fluid level sensor submerged in the compensation jar ; the level is at the minimum. Immediately, a first minimum level pulse is transmitted directly or to the computer by said sensor which activates said red brake fluid level warning light, on the instrument panel and on the replica on the new control panel, which in turn simultaneously activates the solenoid valve-injector of the proactive brake fluid circuit in order to allow it to automatically release, from its auxiliary reservoir, a quantity of brake fluid directly in said reservoir or elsewhere in the brake circuit , to complete the level. Once the brake fluid level in the reservoir has reached the maximum level, a second maximum level pulse is transmitted directly or to the computer by said sensor which deactivates said red brake fluid level warning light on the instrument panel and on the new control panel which in turn again deactivates at the same time the solenoid valve-injector of reserve brake fluid. The problem of low level in the compensation jar is solved there.

The brake fluid injector fixed under the compensation jar, opens exactly at the level of its compensation hole coming from the master cylinder which is located below the level of the fluid, so that there is no introduction air in the circuit as to compensate for the variations in volume linked to the temperature (of the air and of the circuit).

Car warning lights, red alarm.

We find the battery, engine oil pressure, engine oil temperature, coolant temperature and a problem with braking. These red warning lights 35 warn the driver (danger) that he must immediately stop his vehicle. Some red warning lights always come on before the engine is started and then go out. If this is not the case, a repair is necessary because the vehicle is no longer roadworthy.

Appearance of the red oil pressure warning light.

The engine oil pressure warning light is easily identifiable thanks to its red pictogram representing an oil can with a falling drop.

Appearance of the red oil temperature warning light.

It always takes the form of the symbol of a red thermometer, placed above the oil burette with a falling drop.

Appearance of the red coolant temperature warning light.

It is always in the form of the symbol of a red thermometer, with 2 waves represented in the lower part symbolizing the coolant.

Engine oil and coolant: Failure to perform the top-up recommended by the activation of the indicator light for an orange low level warning of one of these fluids, on the instrument panel, will lead inexorably to to a decrease or a lack of one of the two. Failure to do so will cause insufficient pressure and excessively high temperature in the circuit to damage or destruction of the engine if the driver does not stop the vehicle and turn off the engine immediately. Beyond 1 liter of engine oil per 1000 km it will take 15 questions and if you have to add coolant every 1000 km, there is a good chance that you will find a leak. For example, engine oil leakage that can activate the red warning light for insufficient pressure or too high temperature on the instrument panel is often caused by a crankcase damaged by shock, fatigue or unscrewing of the gasket. crankcase bleed screw, oil seal, rocker cover gasket, cylinder head gasket or a leak in the oil cooler / oil - water exchanger, oil filter, etc. While the coolant leak that can activate the indicator light of the red temperature too high alarm is very often caused by the condition of the radiator, cylinder head gasket, water pump, loosening or breaking up of the rubber from a hose that appears over time, a clamping ring or clamp that is not tight enough.

Red alarm scenario.

Let's say, while driving, that the oil pan is punctured or that the radiator is damaged or that a hose of the brake circuit is cut and that you lose one of the fluids without knowing it or that the engine oil tank or Whether the coolant reservoir or the brake fluid reservoir, reserve, are at their minimum levels, this new proactive capability acquired will automatically detect the rapid and sudden drop in fluid level in the crankcase, the fluid reservoir. expansion tank, the compensation reservoir or the reserve brake fluid reservoir. The red warning light for insufficient pressure, high engine oil temperature, high coolant temperature or low reserve liquid level will light up, activate the time delay relay acting as a fuse in order to trigger the proactive circuit of automatic engine shutdown intermittently, i.e. jerkily. As long as said red light remains on, the intermittent frequency will prevent the driver from forcing the engine to rev up to run without oil in order to avoid destruction.

The new automotive time delay relay is programmed to automatically shut off the 40 engine running intermittently to isolate it downstream from disastrous consequences that could come from upstream. The command is the characteristic pulse, negative or positive, which simultaneously lights also one of the replicas of the three (03) red warning lights for insufficient pressure and too high engine oil temperature, for coolant temperature. too high and / or the three (03) minimum level sight glasses for the engine oil, coolant and brake fluid reserves.

It will be essential to establish a new wire connection between the time delay relay (fuse), the starter contactor (wrongly called Neiman) and the computer for the characteristic pulse in order to simultaneously capture the communications between the probes connected to the components and their indicator lights. red alarm on the dashboard. The same information which activates the relevant red LEDs will also activate said fuse.

Everything no longer relies on the driver's responsibility but also depends on proactive engine management, and therefore on its new automatic standby system. With this method, active management allows the engine of the transport vehicle, directly or via its electronic computer, depending on the type of pulse, in its alert phase caused by low levels of engine oil, coolant. and brake fluid, instantly activate the proactive automatic fluid injection circuit.

The solenoid valve of the injector-venturi of the proactive circuit concerned will activate and directly draw off a volume of fluid from its storage tank, in order to make a top-up to automatically correct the low level signaled and prevent it. lack.

In its alarm phase, caused by too low brake fluid level, too high temperatures and insufficient engine oil and coolant pressure, instantly activates the automatic engine shutdown. The timing relay of the proactive circuit of the second component will deactivate and automatically cut off power to the motor intermittently in order to isolate it to prevent it from being restarted.

Proactive management will manifest itself instantly during the onset of the vehicle's orange alerts (drop in fluid level) and red alarms (critical lack of fluids). It is put into practice by the new scaled proactive management process, which can simultaneously integrate several separate and independent proactive circuits, injection and a single (01) 25 proactive circuit for automatic quarantine of the transport vehicle. With regard to the more complex characteristic pulse of the probes, the processing and display of information by the indicator lights on the instrument panel requires passing through a dedicated electronic computer. But when it is simpler positive or negative, the processing and display of information by said LEDs can be direct.

An inexperienced, tired, distracted, little looking, playful driver etc ... presents all the risks of leaving the orange warning lights and red alarm lights directly affecting the engine to a point of no return. No engine is immune to potential qualitative, quantitative and functional failures of these vital fluids. For a person borrowing a vehicle without checking its fluid levels, this innovation will automatically take care of their engine, in place of the usual user. These devices avoid the recurring morning chore of checking fluid levels and adding top-ups, if necessary, before starting the engine. In all automotive service manuals, it is imperative to recommend for the engine lubrication, engine cooling, vehicle braking and windshield washer system to always have a reserve in the boot for top-ups if needed. . The invention avoids carrying flying cans of fluids in its trunk for manual supplements and anticipates the occurrence of potential engine damage.

An audible alarm in the passenger compartment will signal the process of injecting engine oil into the engine lubrication system, the process of injecting coolant into the engine cooling system and the process of injecting oil. brake in the vehicle braking circuit.

The innovation will be better understood through the following figures:

• Figure 5 shows, in front view, the abstract drawing of the entire process for proactive management of orange / yellow alerts and red alarms, of the internal combustion engine of the transport vehicle and on a fixed frame.

• Figure 6 shows, in front view and in DD section, the multi-compartmentalized reservoir bearing the marking reserve engine oil (44) for topping up the engine lubrication circuit, reserve cooling liquid (34) for the engine. '' make up the engine cooling circuit and reserve brake fluid (74) to top up the vehicle's braking circuit.

According to embodiment 1, figure 1 shows the new proactive circuit for automatic injection of engine oil into the engine lubrication circuit, in the event of an orange alert and consists of an individual tank or a reserve compartment sized and marked engine oil (44) of the multi-compartment reservoir (engine oil, coolant and brake fluid), for engine lubrication with a maximum level (48), an intermediate level (48i) and a minimum level (49 ), fitted with a reserve oil level sensor (46). It comprises an electric pump (45), a solenoid valve-injector-venturi (43) connected to the buzzer (bl) and wire by (14), (15) and (16) to the computer (18) and a pipe (47) connecting said pump (45) to said injector (43).

At the level of the new control panel (la) of the invention protected by a fuse box (1b), the replica (5r) of the existing orange warning light (5) connected to the buzzer (b2) of a audio control unit (b), which is also connected to the probe (41) to directly capture the impulses in order to avoid affecting the integrity of the dashboard, a new dual orange warning light (6) (6a ) and red alarm (6b) for the engine oil reserve level in the 40 compartment (44), a green indicator light (7) connected to the buzzer (b3) for the status of the device (fig.l) and one (01) push button (17) with four (04) position switch (17a) (17b), (17c) and (17d) to manually activate the solenoid valve-injector-venturi (43) to top up the crankcase oil (40), if there is a lack of oil when checking the level. The push button (17) will have to be pulled slightly towards you before turning it to select a position, then release it so that it engages and press to inject.

Otherwise, it will be impossible to rotate it. It is a tactile connector used to provide the momentary electrical connection or the temporary opening of the electrical contact. Each selection of position (17a) allows current to flow through the solenoid valve-injector-venturi (43), which activates the injection of engine oil. When the contact is released, it returns. Current flows through the circuit only while the button is pressed.

The controller also has a Test button (17th) connected to the built-in buzzer (bl7) to test the functionality of the entire system and should be used only with the injectors disconnected to prevent unintentional pumping of fluid. These are the means of interaction between man and the process.

In the reserve engine oil compartment (44), the orange warning light (6a) of the twin light monitors the maximum (48) and intermediate (48i) level while its red alarm light (6b) checks the minimum level (49). If the reserve oil quantity is at the intermediate level (48i), it is the orange warning light (6a) which lights up on the control panel (la) in order to passively inform the driver of the need. immediate complement. If the quantity of reserve oil drops to the minimum level (49), the red warning light (6b) lights up on the panel (la) and instantly activates the proactive automatic engine cut-off circuit. (fig. 4) in order to force it to refill the reserve compartment (44).

The pump (45) is connected to the vehicle battery and has a filter, a pressure regulator and an electric motor to suck the oil stored in the container (44), to supply the sump via the line (47). When the regulator detects a minimum pressure in the proactive oil circuit, the electric motor (45) starts automatically to rebalance the pressure. With the engine oil already under pressure, said injector (43) will be provided with a solenoid valve (18) allowing the pump to pressurize the oil in the make-up circuit before spraying it. The orifice of the injector (43) is governed by a valve which locks the oil between it and the pump (45). The desired pressure will be that necessary to introduce the additional oil inside said already pressurized lubrication circuit. Thus as soon as the solenoid valve injector (43) receives the pulse through its wire connection (15), its valve opens and the oil is sprayed directly into the engine oil pan (40) or elsewhere.

The existing oil level sensor (41) is immersed in the oil contained in the crankcase (40) provided with a minimum level (59) and a maximum level (58). It is wired (14) to its existing orange oil level warning light (5) and (5r) and sends a positive (12 / 24v) / negative (-) electrical signal directly, or characteristic via a engine management computer (18), which displays its status, on the instrument panel (1). In addition to the existing wired transmission (14) of data between the existing oil level sensor (41) to measure the level and the existing orange oil level warning light (5) to visualize the level. status on the dashboard (1); a new wired communication (16) will be established with the injector-venturi solenoid valve (43) of the circuit (fig.l) and the replica (5r). To keep the proactive circuit alert, 40 the oil reserve level sensor (46) will continuously transmit its data to its oil reserve level bivouac (6) to indicate its status on the control panel (the ).

The injection of oil into the crankcase (40) or elsewhere in the lubrication circuit depends on the mode of the type of injector chosen and on its mode of regulation. The same is true for the duration 45 of activation of the indicator light (5) and (5r).

IIIIIIIIIII • If the injector opening time is programmed (in general an injector is programmed for a precise opening and closing time to inject a certain quantity), then its command activates and deactivates it in order to spray several jets of oil intermittently until the orange indicator lights (5) and (5r) are deactivated.

If the injector opening time is not programmed then as long as the orange LEDs (5) and (5r) are lit on the panel (1), the control activates a continuous jet of oil until their deactivation.

The oil level corrected and taken into account by the existing oil level sensor (41), the orange oil level warning light (5) and (5r) go out. The problem of low oil level (59) in the engine oil pan (40) is then resolved. In turn, the orange warning light for the reserve oil level (6a) located in the auxiliary tank (44) could light up on the panel (la), if the volume of oil punctured from said tank (44) is such that the remaining oil has reached the intermediate level (48i). The driver must then top up the level up to the maximum level (48) in order to prevent it from reaching the minimum level (49) causing the red warning light to illuminate the reserve oil level. (6b).

However, a malfunction of the warning or alarm system, so here of the oil level sensor (41) located in the crankcase (40) could activate the untimely lighting of said existing orange warning light (5). therefore simultaneously also its replica (5r) and cause unwanted oil injections 20 which could cause an overflow in the crankcase (40). Too much oil can cause damage as well. That is to say that the maximum level (58) is good in the oil pan (40) but the sensor (41) sends erroneous data to the existing auditory orange warning light (5) on the instrument panel (1). To overcome this, the injector will be fitted with a venturi tube. This device has long been used in service pumps at fuel stations 25 which stops the injection when the tip of the gun inserted into the tank bathes in the fluid.

In our case, at the oil sump (40) or elsewhere in the engine lubrication circuit, the solenoid valve-injector-venturi (43) will be positioned so that, when there is a lack of 'oil, the tip of said injector is emerged out of the fluid and when the level is good, that the tip is submerged therein. This is to promote the correct operating cycle of the venturi tube, that is to say injection or shutdown. The role of the new fuse box (lb) of our control panel is to protect its electrical circuit (fuses and relays).

According to embodiment 2, figure 2 shows the new proactive circuit for automatic injection of coolant into the engine cooling circuit, in the event of an orange alert and consists of the individual tank or the dimensioned reserve compartment. and marked coolant (31) for engine cooling with a maximum level (33), an intermediate level (33i) and a minimum level (34) provided with a reserve coolant level sensor (32) . It includes an electric pump (35), a solenoid valve-injector-venturi (25) connected to the buzzer (b4) and wire by (14), (15) and (16) 40 directly or to the computer (18) and a pipe (29) connecting said pump (35) to said booster injector (25). The minimum level (34) of reserve coolant in the compartment (31) can also activate the automatic engine shutdown process (fig. 4) via the red warning light (9b) of the twin indicator light (12). level in order to force the driver to top it up again.

At the level of the new control panel (la) of the invention, there is provided the replica (8r) of the existing orange warning light (8) and connected to the buzzer (b5), which is also connected to the probe (22) for directly capture the impulses, a new dual indicator light (9) for orange warning (9a) and red alarm (9b) for the coolant reserve level in the compartment (31), a 5 green indicator light ( 10) connected to the buzzer (b6) for the status of the device (fig. 2). The switch in the position (17b) of the push button (17) will be used to manually activate the solenoid valve-injector-venturi (25) for a make-up.

IN THE EXPANSION VASE DUE TO TEMPERATURE FLUCTUATION.

The expansion vessel (20) (overflow tank) is part of the cooling circuit, it has 1 minimum level (24) and 1 maximum level (23). In general, it is connected to the radiator (30) by the overflow pipe (28). These minimum (24) and maximum (23) levels make it possible to contain by compensating for variations in the volume of the cooling liquid due to the phenomenon of thermal expansion (increase in temperature). It is also a reserve of liquid and the place by which the circuit is filled. A level sensor (22) signals a possible lack of liquid on the dashboard (1) via its existing warning light (8). Pressurizing the cooling circuit lowers the boiling temperature of the coolant. In fact, when the liquid boils, it forms gas pockets which prevent the circulation of liquid and the cooling, hence the advantage of reducing the boiling point. In general, the capacity is 5 to 7 liters which quickly escape through the slightest sealing defect. For a pressurization of 1 bar, the boiling point of the liquid is pushed back by 18 ° C (the boiling point at atmospheric pressure of a conventional coolant is 107 ° C). The airtight cap of the expansion tank has two (2) valves:

• A pressure relief valve (21): When said liquid heats up: It increases in volume, part of the water from the radiator (30) fills the vessel (20), the air pressure included in said vessel (20 ) above the water increases, from a certain pressure (0.5 to 2 bar), the pressure valve (21) opens, allowing air to escape through the outlet ( 27), to stabilize the pressure in the vessel (20) at the maximum value (23). This valve (21) allows the pressurization of the circuit in the event of overpressure. These are the “safety valves” of the cooling system;

• A vacuum valve (2Γ): When the coolant cools: Its volume decreases, and part of the water leaves the vessel (20) through the hole in the bottom (26) to return to the radiator (30) through pipe (28), the air pressure drops in the vessel (20) and if it becomes too low, a vacuum is created.

The valve (21 ’) opens allowing a certain amount of air to enter the vessel (20) necessary to obtain a minimum pressure. When the vehicle stops, as it cools, it decreases in volume, and a vacuum is created in the circuit. At this point, the vacuum valve (21 ’) opens, allowing atmospheric pressure to be brought up, and preventing the hoses (28) from crashing.

In conclusion, this new device (fig. 2) for adding coolant is similar to compensating for variations in the volume of the coolant due to the phenomenon of thermal expansion.

The addition of coolant when it is injected into the expansion tank (20) from the bottom of the latter, will have the same characteristics as during normal operation of the cooling circuit, i.e. the increase in volume of liquid in the expansion tank (20), when the engine temperature increases.

Also for this case, at the level of the expansion tank (20) or elsewhere in the engine cooling circuit, the solenoid valve-injector-venturi (25) will be positioned, as previously for the case of engine oil. in the housing, to promote the correct operating cycle of the venturi tube, that is to say injection or shutdown.

According to embodiment 3, Figure 3 shows the proactive circuit for automatic injection of brake fluid into the vehicle's brake system, in the event of a red alert, and consists of. individual tank or reserve compartment dimensioned and marked with brake fluid (70) for braking the vehicle with a maximum level (73), an intermediate level (73i) and a minimum level (74) fitted with a level sensor brake fluid reserve (72). It comprises an electric pump (75), a solenoid valve-injector-venturi (77) connected to the buzzer (b7) and wire by (14), (15) and (16) directly or to the computer (18). A line (76) connects the booster pump (75) to the injector (77). For safety, the minimum level (74) of reserve brake fluid in the compartment (70) will activate the automatic engine shutdown process (fig. 4) via the red warning light (12b) of the dual warning light ( 12) level in order to prevent the driver from using the vehicle if the required reserve brake oil level is at the minimum, thus preventing traffic accidents.

At the level of the new control panel (la) of the invention, there is provided the replica (1r) of the orange warning light (11) connected to the buzzer (b8), which is also connected to the probe (81) for 25 to capture the impulses directly, a new dual warning light (12) for orange warning (12a) and red alarm (12b) for the brake fluid reserve level in the compartment (70) and a green warning light ( 13) connected to the buzzer (b9) for the status of the device (fig. 3).

The switch in the position (17c) of the button (17) will be used for manual activation of the solenoid valve-injector-venturi (77) for a make-up. In this case too, at the level of the compensation jar (80) or elsewhere in the vehicle braking circuit, the solenoid valve-injecteurventuri (77) will be positioned, as previously for the case of the engine oil in the vehicle. crankcase (40) and coolant in the expansion tank (20), to promote the proper operating cycle of the venturi tube, that is to say injection or shutdown.

According to Embodiment 4, Figure 4 shows the proactive circuit for automatically quarantining the engine in the event of a red alarm and completes the engine compartment with a new five (5) terminal automotive time relay (60). A terminal (85), (86), (87) (87a) and (30). The coil is supplied by terminals (86) and (85). Here, the terminal (86) receives via the wire link (61) or (62) or (66) the characteristic signals either from the computer, positive (12 / 24v) or 40 negative (-) directly, for activating the indicator lights. 'red alarm (2) and (2r) or (3) and (3r) or (4) and (4r) or (6b) or (9b) or (12b) when at least any one of the six (06) lights up. Several signals, equivalent to as many problems. Consider here that the signal is positive (12 / 24v), the hazard warning lights and the horn will also be connected to terminal (86). The terminal (85) is connected to the ground (51) via the wire link (65). The normally open terminal (87a) is connected to ON (53) of the key (50) by the wire link (64).

The terminal (30) is connected to the ACC (52) of the key (50) by the electric wire (63). Terminal (87) is activated when current is lost at terminal (87a), it is the engine cut-off intermittently, therefore activated by a red alarm (2r) or (3r) or (4r) or (6b) or (9b) or (12b).

At the level of the new control panel (la) of the invention, replicas (2r), (3r) and (4r) of the red alarm indicators (2), (3) and (4) are provided, connected to the buzzer (blO), (bl 1) and (bl2), also connected to the probes directly. The red dual alarm lights (6b), (9b) and (12b), connected to the buzzers (bl3), (bl4) and (b 15), reserve level sensors are already installed.

A green indicator light (13a) connected to the buzzer (bl6) for the status of the device (fig. 4). The 10 switch in the position (17d) of the button (17) will be used for manual activation of the time relay (60).

Intermittent deactivation of the time delay relay will therefore be dictated by the failure of:

• Engine lubrication circuit lighting the LEDs of the replicas of the red warning lights 15 for insufficient pressure (2) and (2r) and too high engine oil temperature (3) and (3r);

• Engine cooling circuit lighting the led of the replica of the red warning light for too high coolant temperature (4) and (4r).

• Three (03) circuits of compartments (44), (31) and (70) lighting the leds of the replicas 20 of the red alarm indicators (6b), (9b) and (12b) of the minimum levels of the reserve fluids ( 49), (34) and (74).

The novelty consists in connecting together by wire the six (06) red alarm lights (2r) and (3r) and (4r) and (6b) and (9b) and (12b) to the terminal (86) of the time delay relay ( 60) acting as a fuse, in order to transmit the pulse of their red alarms independently. But we are still faced with two (02) possibilities, in the event of a critical lack of fluids:

• If the auxiliary compartment concerned (31), (44) or (70) is at its maximum level (33), (48) or (73) or intermediate (33i), (48i) or (73i) then its pump (35), (45) or (75) will activate and inject the fluid, topping up is done and after the circuit has been reset by the computer (18), respectively the orange indicator light (5r) connected to the engine oil level 30 (46), (8r) connected to the coolant level sensor (22) and / or (1 Ir) connected to the brake fluid level sensor (41) goes out putting the engine out of danger; the time delay relay (60) acting as a fuse is not activated.

• If the auxiliary compartment concerned (31), (44) or (70) is at its minimum level (34), (49) or (74), then it will trigger the lighting of the red light (6b) or ( 9b) or (12b) which in turn will activate the time delay relay (60) which will intermittently cut off the fuel supply (fuel solenoid valve) or / and electrical (53) to the engine (ignition or engine stop), after programmed time to prevent restarting.

The signal transmitted by the wire link which activates the engine shutdown process, simultaneously activates an internal light and sound warning device in the vehicle passenger compartment for the driver and automatically triggers the "Hazard warning lights" system and the horn for the warning device. exterior of the vehicle to warn surrounding road users of a problem in order to signal the start of the engine shutdown process.

Thanks to this time relay, there will be a gradual drop in engine speed because the intermittence of the cut will prevent acceleration and promote deceleration as and when to allow the driver to get out of the queue to park safely. safety before the allotted time completely disables the electrical supply to terminal (86) 5 coming from the ON terminal (53) of the key (50). This deactivation will persist for as long as the red alarm light is on. The engine will not restart as long as one of the red warning lights (2r) and / or (3r) and / or (4r) and / or (6b) and / or (9b) and / or (12b) remains alight.

The relay (60) will open / close and therefore snap according to its programming in order to secure the health of the engine by preventing it from revving up during this programmed time.

The frequency of intermittency should prevent acceleration but should not shut off the engine. After this time, the relay closes and completely cuts off the engine. The frequency of the intermittency of the relay is adjustable and will be specific to each vehicle.

The new automotive time relay is programmed to automatically shut off the 15 running engine intermittently to isolate it downstream from disastrous consequences that could come from upstream.
