Description

Water spray structure of intake cylinder of internal combustion engine {A WATER FUNNEL ASSEMBLY OF ENGINE}

The present invention relates to an engine intake cylinder of an internal combustion engine, and more particularly, an internal combustion engine for improving combustion efficiency of an engine by allowing a water content to be proportionally increased in accordance with a driving suction force of intake air sucked into an engine combustion chamber. It relates to a water spray structure of.

In general, a car does not cause any problems when driving at low speeds, but when driving at high speeds (usually 80 km per hour or more and 1500-2000 RPM or more), a large amount of fuel is injected into the engine to improve the inner bomber to increase output in the combustion chamber. As such, a large amount of fuel injected during high-speed driving increases exhaust gas emissions due to incomplete combustion, and increases fuel consumption, causing a decrease in engine output.

Therefore, in order to prevent the fall of the inner explosion of the engine during high-speed driving, it is well known that a method of improving the engine output by reducing the injection of water into the combustion chamber independently from the fuel and reducing the generation of exhaust gases is known. Hereinafter, a description will be given of the prior art in which such a water spray device is disclosed.

First, in Patent Publication No. 91-20311, a technical subject is to inject some fuel into an engine, and then to inject water and then to inject the remaining fuel into the engine. After the water is injected, the injected water does not increase the output of the engine, and the injected water absorbs the heat of the exhaust gas, so as not to reduce the smoke, and also does not burn even if the secondary fuel is injected. Since it is turned into an exhaust port directly to cause a problem that eventually increases the smoke.

In addition, the sequential operation of the first fuel injection, the second water injection, and the third fuel injection through the nozzle complicates the structure of the fuel injection device of the internal combustion engine, and the problem of installing another water injection brand and the life of the parts. When water stays in a fixed place for about three months, impurities are generated in the water, and impurities accumulate in the water flow path and the injection device Bran and the water spray nozzle, causing the nozzle to be clogged. The complex molding of the product and the economical cost are also excessively used, and the cost of repairing the trouble will be excessive. Also, the cost is excessively expensive to be installed in the internal combustion engine.

In addition, Korean Patent Publication No. 97-70512 relates to an internal combustion engine characterized by injecting water into a cylinder immediately before or after the ignition period, which is immediately before the ignition period, that is, when the piston injects water during compression stroke, Since there is no time for vaporized water to vaporize, it is impossible to make water vapor, which causes water to be adsorbed on the spark plug, which causes a problem of ignition. In addition, if water is injected immediately after the ignition period, that is, when the piston descends, the temperature of the exhaust gas in the combustion chamber is lowered, which causes the function of the catalytic converter, the exhaust gas purification device, to be deteriorated. When water is injected at the time of arrival, the heat of compression of the combustion chamber will be lowered, which leads to a decrease in combustion efficiency. In addition, if water is injected immediately after the ignition period, water is injected after the explosive stroke, so the water absorbs heat from the exhaust gas. As the function of the converter decreases, the purification capacity of the exhaust gas decreases, so the amount of smoke generated increases.

In addition, Korean Patent Publication No. 97-11375 discloses that a venturi mechanism is installed between an air filter and a carburetor to improve the combustion performance of an engine by injecting water from a water tank into the air through a pipe. In this case, the venturi tube floats in the air, so that the bearing capacity becomes weak, and the air inflow rate cannot be injected precisely from the low speed to the high speed region, and only works in the high speed region, thus effectively exhibiting irregular performance.

According to the above, it can be seen that the efficiency of the flame retardant is determined according to the time of supplying water to the engine, the rotation ratio of the engine, and the amount of water sprayed. When the water enters the combustion chamber, the efficiency of the engine varies greatly depending on the quantity of water. It can be seen that.

When the water flows into the liquid state more than the volume ratio of the combustion chamber, the piston compresses the water introduced into the combustion chamber, so that the connecting rod and the parts of the piston connecting the crank and the piston are also damaged.

In addition, the output deviation of the engine is generated depending on how the molding of the water spray device and the intake air are introduced. When the water supplied to the engine and the fuel are not evenly mixed, or even when the supply ratio is not constant, the output of the engine is not constant at low or high speed, and may cause a problem of lowering the engine output.

Therefore, proper water and mixed air should be evenly mixed with the fuel according to the engine suction power so that the combustion efficiency of the engine can be evenly increased from low speed to high speed. At the same time, it can be seen that fuel saving and exhaust gas reduction effect can be obtained.

That is, the present invention has been proposed in view of the above-described problems of the prior art, and the temperature of the intake air is sprayed so that appropriate moisture can be variably supplied into the intake flow path in accordance with the intake force of the intake air supplied to the internal combustion engine engine. The purpose is to reduce the pressure and at the same time improve the combustion efficiency.

There may be many embodiments of the present invention including the above components as a technical gist, and hereinafter, the most suitable embodiments will be described to examine the objects, features, and effects of the present invention.

Hereinafter, a water spray internal combustion engine of the present invention will be described in detail with reference to the accompanying drawings.

1 is a structural diagram of an engine intake system according to an embodiment of the present invention, Figure 2 is an enlarged cross-sectional view of the water supply of the embodiment, Figure 3a and 3b is a view showing the operating state of the water supply.

First, referring to FIG. 1, a schematic configuration of an intake cylinder according to an embodiment of the present disclosure is provided with an air cleaner for preventing foreign substances such as sand or dust contained in the air sucked by the driving suction input of the engine. 1), a vaporizer 2 for mixing fuel to the intake air and supplying it to the combustion chamber 5, a water supply unit 3 for supplying water molecules to the intake air passing through the vaporizer 2, It consists of an intake manifold 4 which guides the moisture-intake air to the engine combustion chamber 5.

In the figure, reference numeral 6 denotes an exhaust manifold for discharging the combusted exhaust gas.

On the other hand, the water supply unit 3 of the present embodiment is composed of an air induction plate 10 and the funnel portion 11 of the funnel shape, the water supply pipe 12 and the mixed fan 13, which will be described in more detail with reference to FIG. Shall be.

That is, the water supply unit 3 provided with the throttle accelerator pedal governor 9 on the suction side has the same three-layer flow channel structure, and the funnel-shaped funnel portions 11a, 11b, and 11c are gradually audited. Air induction plate (10a, 10b, 10c) is provided in the forward proportional opening operation by the drive suction input of the engine forward, each air guide plate (10a, 10b, 10c) has a lower end as the drive suction input of the engine increases The air induction plate (10A) of the sequential opening to automatically adjust the proportional automatic supply of air and water during the intake stroke of the engine.

At this time, the funnel portion (11a, 11b, 11c) of each intake guide pipe is connected to the supply pipes (12a, 12b, 12c) for supplying water from the water storage unit 14, respectively, to control the supply of water to each supply pipe An on-off valve 15 is mounted.

In addition, the weights a, b, and c are formed on the air induction plates 10a, 10b, and 10c of the intake passages with different loads (a <b <c). Mixing pans 13a, 13b and 13c for mixing the sprayed water evenly were mounted respectively.

The operation and operation of the present invention configured as described above will be described.

First, since the temperature in the combustion chamber 5 is low in the initial operation of the engine according to the initial operation, even though the open valve 15 blocks the supply pipes 12a, 12b, and 12c for spraying water, air is sucked in through the suction flow path. Water will not be supplied.

Then, when the engine is rotated at a high speed, as the output is increased in the engine combustion chamber 5, the required inner width material also increases, and the internal temperature also rises at the same time.

As such, when the combustion chamber temperature of the engine rises, the opening / closing valve 15 detects this to open the supply pipes 12a, 12b, and 12c.

When the supply pipe is opened, as shown in FIG. 3B, the air induction plate 10a in the intake induction pipe located at the bottom in accordance with the driving suction input of the engine is opened, and the water storage unit 14 is proportional to the pressure of the intake air. As the water being stored is raised through the supply pipe 12a, it is sprayed into the flow path through the funnel portion 11a.

At this time, since the air induction plate 10 is formed in each layer to vary the weight of the weight (a, b, c), the air induction plate 10a at the bottom as the suction driving power of the engine is gradually increased. From the top to the air induction plate in sequence (10b → 10c) to open operation, as the intake drive power of the engine is gradually increased in this way as the area of the open flow path is increased to increase the spray amount of water in proportion.

In addition, the combustion chamber 5 in the state in which air and water sucked into the combustion chamber 5 through the intake manifold 4 are evenly mixed by the mixing fans 13a, 13b, 13c rotating by the driving suction input of the engine. Can be supplied.

In this way, it is possible to properly supply the inner explosives necessary for the operation of the engine into the suction flow path while spraying appropriate air and water in accordance with the engine's intake driving force.

In addition, when the engine operated at high speed rotates at low speed again, the pressure of the intake air gradually decreases, thereby closing the intake flow passage while closing the air induction plate 10c at the upper end of the relatively heavy weight. The amount of water spray can be reduced proportionally.

As a result, the water spray structure of the present invention increases the output of the engine with a small amount of fuel by increasing the pressure in the combustion chamber 5 of the engine in a state in which the proper water and air are proportionally supplied according to the intake driving power of the engine. Fuel savings, as well as exhaust emissions due to complete combustion, can be achieved.

As a result, the emission of the exhaust gas is suppressed as much as possible so that soot and harmful gas generation can be prevented.

The present invention as described above, by varying the amount of sprayed water in accordance with the suction amount of the air supplied to the engine combustion chamber through the intake pipe during the high-speed operation of the internal combustion engine to increase the water content of the intake air and to the sprayed water This allows the high heat of the engine to be absorbed.

Accordingly, the combustion efficiency in the engine is increased to increase the output, and together with this, it is possible to reduce the smoke generation of the exhaust gas, thereby improving the air pollution problem.
