Description

Air volume control device of internal combustion engine

The present invention relates to a device for controlling the air volume of an internal combustion engine, and more particularly, to improve the combustion efficiency of an internal combustion engine by controlling the amount of air sucked into the internal combustion engine according to the operating environment, thereby increasing the output of the engine, reducing soot, fuel consumption. It relates to an air volume control device of an internal combustion engine that can achieve a reduction of energy.

An internal combustion engine is an engine that converts thermal energy containing fuel into mechanical work by directly acting on a piston or a turbine blade (flag), etc., generated by burning fuel, and collectively refers to a vehicle, a ship, a boiler, and the like.

The basic operation of the internal combustion engine consists of intake, compression, explosion and exhaust stroke.

In the intake stroke, the intake valve opens and a mixture of fuel and air enters the cylinder.

In the compression stroke, the intake valve closes and the piston compresses the mixed gas.

In an explosive stroke, sparks splash from the spark plug and the mixture explodes, moving the piston.

In the exhaust stroke, the exhaust valve is opened to exhaust the combustion gas.

At this time, when the fuel is incomplete combustion state, the fuel efficiency of the internal combustion engine is lowered, and the harmful gases that are the main causes of air pollution and global warming, that is, a large amount of smoke is emitted.

Therefore, in recent years, in order to realize the complete combustion of the internal combustion engine, a method of controlling the amount of air entering the engine has been studied, but an appropriate method has not been developed yet, and thus it has not been generalized.

On the other hand, the reduction effect of the exhaust gas decreases as the oxygen concentration increases, and when the air having an oxygen concentration of 27% is used, the volume of the exhaust gas is known to decrease by about 20% compared to the air having an oxygen concentration of 21% ( Jae-Ho Cha and 13 co-authors, 545p).

Although it is known that it is efficient to burn by supplying high concentration of oxygen in this way, the existing internal combustion engine uses more than 78% of nitrogen and other components in the air for combustion activities, resulting in low combustion efficiency and sparking unnecessary pollution. It is the cause of letting.

In addition, when a person walks slowly, runs fast, and breaths are different at high and low temperatures, when the engine accelerates or runs at low speeds, the amount of air supplied depends on the ambient temperature. However, in the past, it was not easy to precisely control the air volume because the air volume is controlled only by the accelerator pedal in the same state regardless of the operating speed or ambient temperature.

Accordingly, an object of the present invention has been devised in view of the above-described point, it is possible to adjust the amount of air sucked into the internal combustion engine in accordance with environmental changes, such as operating speed or atmospheric temperature conditions, to increase the ratio of oxygen in the air sucked It is to provide an air volume control device of an internal combustion engine to improve the combustion efficiency to increase the power output of the engine, reduce soot, and reduce fuel consumption.

In order to achieve the above object, the air amount adjusting apparatus of the internal combustion engine according to the present invention includes a housing having a suction hole formed on one surface thereof and an opening formed on the other surface thereof, and being installed inside the housing, and the suction hole rotated by a fan. An intake fan for increasing the ratio of oxygen in the air sucked through the air, and a suction control window corresponding to the suction hole, and an air suction amount adjusting means for adjusting the size of the suction hole by the suction control window to adjust the air intake amount; .

Apparatus for adjusting the air volume of an internal combustion engine according to the present invention has the following effects.

First, it is possible to easily adjust the air intake to the engine according to the season or ambient temperature or temperature change or the running speed.

Accordingly, by operating in a combustion state close to complete combustion, there is an effect that can improve fuel economy and fuel savings.

In addition, by reducing the fuel consumption it is possible to suppress the generation of carbon dioxide, noise and vibration can be reduced to maintain a comfortable operating state.

Second, it is possible to improve the engine output by adjusting the pressure of the intake air.

Accordingly, the vehicle failure rate is also lowered, thereby increasing the economic efficiency and increasing the user's satisfaction.

As a result, as shown in FIG. 2, the coupling of the air volume control device of the internal combustion engine is completed, and the coupling of the air volume control device of the internal combustion engine that is completed is coupled to the air intake pipe 10 of the air intake device as shown in FIG. 3. .

In this embodiment, as shown in FIG. 3, the air cleaner 20 is installed inside the air intake pipe 10 connected to the intake manifold in the intake apparatus of the vehicle engine.

The air cleaner 20 serves to remove dust and the like in the air sucked into the intake manifold.

A filter is built in the air cleaner 20, and the installation position is at the bottom of the filter.

In this state, the operating lever 420 is installed at an appropriate position in the driver's seat so that the vehicle driver controls the opening degree of the suction control window 310 of the rotating plate 300.

The operation lever 420 is connected to the cable 410 so that the cable 410 is pulled or released according to the operation of the operation lever 420.

In this embodiment, the operation lever 420 is fixedly connected to the handle 421 and the end of the cable 410, as shown in Figures 4a and 4b and moved at regular intervals according to the pull of the handle 421 It consists of a moving member 422 to pull the cable 410.

When the vehicle is running at medium speed or high speed, when the fan driving unit 240 is stopped by “off” the operation of the switch 430, the blade 210 of the intake fan 200 is rotated by the air sucked in.

As described above, the air volume control device of the internal combustion engine is different from the conventional technology in which external air is uniformly sucked through the air suction pipe 10 due to the action of a motor fan installed inside the engine. The technical characteristics of the air intake amount can be adjusted by adjusting the size of the suction hole 110 through which air is sucked in accordance with a change in operating environment.

As the air intake can be adjusted in this way, the combustion efficiency can be improved by allowing the complete combustion by adjusting the intake of the air sucked into the engine according to various conditions such as air temperature and operating environment.

As a result of measuring the oxygen ratio in the inhaled air of the vehicle with and without the apparatus of the present invention, the combustion rate increased as the oxygen ratio was increased relative to the vehicle without the vehicle.

Therefore, as a result of the applicant's experiment, the 25-ton trailer can save 10% of the oil consumption, and the carbon dioxide emission is 100g / km, so that the smoke is significantly reduced and it is in the complete combustion state.

As such, the present invention increases the oxygen ratio of the air supplied into the engine cylinder and lowers the nitrogen ratio, thereby increasing the combustion efficiency by making the engine completely burned.

Furthermore, by adjusting the opening degree of the air window manually or automatically according to the atmospheric temperature situation, it is possible to keep the optimum state at all times by reducing the amount of air at low temperatures and increasing the amount of air at high temperatures.

As described above, the apparatus for controlling air volume of an internal combustion engine according to the present invention may be applied to an internal combustion engine such as a vehicle, a ship, a boiler, and the like, and may be widely used in the parts industry for improving performance and fuel efficiency, and reducing smoke.
