Abstract

PURPOSE:To suppress the fuel consumption quantity in choking and eliminating the engine trouble in a cold state by allowing the warm water in the heat shielded state to forcibly circulate by utilizing the hydraulic flow due to a water pump on the engine start and shortening the warming operation time of the engine. CONSTITUTION:A central drain pipe 3 is arranged on a body 1 having the heat insulation function, and a shiftable partitioning wall 4 is inserted into the central drain pipe 3. A drain port 6 and a warm air circulation hole 5 are formed at the arbitrary position in the upper part of the central drain pipe 3, and the cooling water which flows from a water suction port 2 is allowed to circulate through the drain port 6 and the warm air circulation hole 5. At this time, the shiftable partitioning plate 4 shifts to the drain port 6 and the upper part of the warm air circulation port 5. When an engine stops, the shiftable partitioning plate 4 shifts downward, and assists the heat shielding effect of the warm water in the body The stroke the state where heat shielding is performed once consists of the repetition of heat insulating introduction warming.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] This device is intended to shorten the warm-up time when starting a water-cooled engine.During warm-up, the concentration of combustion gas fuel is high, and the device cannot be used. This invention relates to a heat-insulating cooling water injection device for automobiles, etc., which aims to shorten the time and save fuel.

2. Description of the Related Art Conventionally, the temperature of the cooling water in the cylinder block of a water-cooled engine has the drawback that it takes a long time to warm up the water from a cold water state to a hot water state. In order for the engine to function normally, there is a mechanism that does not return the mixed gas to the normal light gas unless the cooling water in the cylinder block rises to about 50 degrees Celsius or higher. It is common knowledge that there is a strong (Auto choke mechanism, etc.) Also, in order to shorten the time, the engine speed is increased (advancing the ignition and explosion timing), so the mixture is rich during combustion when cold, and
This is a time when unburned fuel is being discharged as it is, and there are many drawbacks such as HC pollution and energy saving problems.

0003

[Problem to be solved by the invention] Warm-up operation is a fuel-rich condition and a large amount of HC is emitted. Many cars are warming up, and if you leave your car behind and go outside, your eyes will sting and your nose and throat will be irritated. Everyone can feel that this condition is HC pollution. Also, if you drive the car repeatedly without warming it up, the plugs will get covered and the engine will stop at one time or another. This is the worst time for many accidents. In addition, cars are now used for multiple purposes, including commuting, leisure, shopping, and business.
Currently, there are many operators who run the train for about 10 minutes, and there are many cars parked there. In the case of an engine, once it is stopped, 3
The cooling water in the engine cools down in about 1 hour from 0 minutes, and since it starts with warming up, the current situation is that one car repeats this many times a day, and it is difficult to warm up the engine when it is cold. The disadvantage is that there is a tendency for more and more trains to operate during the season, and there is no other option.

0004

[Means for solving the problem] The reason is that during warm-up, cold water is forcibly sent into the engine by the water pump, but it takes a considerable amount of time for the cold water to become warm overall. . This is because most people drive before it gets warm. The present invention was developed to solve these drawbacks, and is characterized by storing once-warmed water in a heat-retaining device and keeping it warm until the next time the engine is started.

[0005]

[Example] (a) A main body 1 equipped with a heat retention function has a water intake port 2 at the bottom of the main body so that the process of keeping warm → pouring → warming can be repeated, and a central drain pipe 4 is installed in the center of the main body 1, which includes:
A warm-up circulation hole 5 and a discharge port 6 are provided. (b) The movable partition plate 4 is inserted into the central water pipe 3, but it is not fixed so that it can move freely. (c) The main body provided with these is installed before and after the water pump A of the automobile or at other positions. This design has the above-mentioned structure, and when using this, the normal engine starting procedure is sufficient, and when starting the engine, the warmed water obtained by repeating heat retention → injection → warm-up is forced into the engine. The hot water that was sent and stored in the heat insulator warms up the engine in a few seconds. The movable bulkhead plate moves downward when the engine is stopped, and serves to improve the heat retention effect of the stored hot water.

[0006]

[Effect of the invention] When the engine starts, cold water forcibly sent from the water pump passes through the engine.
After that, when the hot water stored inside the heat insulating device flows through the entire circulation path including the engine, it has the same effect as ending the choke, and has several times the effect on fuel consumption compared to conventional methods, and can significantly shorten the time. . Also, once kept warm, the
The water is hot for more than an hour, but when the inside of the heat retention device is also cold, it is also possible to provide a heater device inside the heat retention device to keep the water hot at all times.

Claims (1)

[Claims] Claim 1: A main body 1 having a heat retention function is provided with a water intake port 2 and a central drain pipe 3, a movable bulkhead plate 4 is inserted into the central drain pipe 3, and a discharge port 6 is provided in the upper part of the central drain pipe 3. and a warmer circulation hole 5. When the engine is started, water pump A operates and begins forcibly circulating cold water. At this time, the movable bulkhead plate 4 inside the main body 1 moves above the warmer circulation hole 5 and the discharge port 6 due to water flow pressure, the stored hot water is injected into the engine, and the cold water inside the engine flows into the main body 1. return. This cooling water moisturizing injection device for automobiles, etc., is characterized by shortening the warm-up time when starting the engine by circulating the warm water that has been kept warm.
