Control system of suction air for internal combustion engine

The present invention is composed of a vortex device in the air intake conduit of the vehicle, the intake conduit and the inlet inlet and the auxiliary air supply valve in front of the air cleaner to control the opening and closing amount by the negative pressure formed in the intake pipe behind the air cleaner By supplying the air according to the output of the car and increasing the vortex phenomenon by the vortex device formed in the front and rear, increasing the heat efficiency by improving the supply and mixing rate of the air needed in the combustion chamber to increase the output, reduce fuel and reduce soot A suction air conditioning system.

As is well known, the automobile manufacturers and their laboratories have conducted a lot of research to improve the output reduction and soot smoke due to the poor combustion, which is a problem in the internal combustion engine, but the specific system is not known so far.

Accordingly, the suction and exhaust vortex devices which form the vortex wing in the car's suction conduit to rotate according to the guide of the wing, that is, the vortex phenomenon, move faster and supply a large amount of air to increase the output. Aka cyclone) is known.

In other words, Korean Patent Application Publication No. 444 of 1991, 4747 of 1992, No. 3,034 of 1995 and Public Utility Model No. 10292 of 1994 and Domestic Publication Utility Model No. 1995 of 1532, etc. Nos. 26247.59-11722, US Patent No. 4.309.969, and Japanese Patent Publication Nos. 60-17922, 61-10645, US Pat. Nos. 4.424.777, 4.432.312, and 4.539.954 No. 3.684.674, 4.274.386 and the like describe a number of vortex devices, and there are also a number of cases other than those shown above.

In this technique, the vortex device comprises a plurality of wings in the cylinder and adjusts the shape and angle of the wings so that the incoming air is rotated in accordance with the guide of the wing. It consists.

Accordingly, the incoming air generates a vortex phenomenon according to the guide of the rotary blade, and can suck a large amount of air quickly.

Such intake air reduces the amount of air by friction with the vanes or creates a vacuum in the center by vortexing, which in turn reduces the amount of incoming air.

In other words, the four-stroke engine compresses air and fuel in a closed space in an appropriate amount, compresses it, and compresses only air with a gasoline engine (including LPG) that is burned by the high temperature of the spark, and then injects fuel to induce spontaneous combustion. It can be divided into two types that use thermal expansion energy (diesel engine).

The former increases or decreases the output by changing the compression ratio, while the latter increases or decreases the output by changing the mixing ratio. Both of these types absorb the basic structure of a four-stroke engine. Since the cycle is completed by the intermittent action of the exhaust valve, it has both structural disadvantages and solving such disadvantages is a research task of the four-stroke engine.

The main disadvantage of four-stroke engines is the intermittent action of the intake / exhaust valves, making it difficult for light mass air or mixers to enter the combustion chamber consistently under erratic operating conditions and to maintain the same energy efficiency at each RPM. Will be close to.

In addition, the uncertainty of replacing the combustion gas and the intake mixer at the intersection of the exhaust stroke and the intake stroke is also a big problem.

In particular, since the four-stroke engine has a large variation in the intake air amount from the low speed to the ultra-high speed, it is also difficult to solve the problem of supplying a proper air amount while maintaining a flow rate corresponding to each rotation speed.

In the four-stroke engine having many problems as described above, an alternative to solve these shortcomings is to use the vortex phenomenon naturally generated by the passage resistance (friction resistance) of the air passing through the intake air pipe.

Vortex is a natural phenomenon where the air passing through the intake pipe becomes a linear motion due to frictional resistance with the wall. The vortex generation efficiency is equal to the flow velocity of the passing fluid. Just do it.

However, since the four-stroke engine has a wide variation in air volume as described above, in order to balance the output of high speed and low speed, the intake air pipe section cannot be made thinner.

In addition, because air is light in mass, sufficient distance to be accelerated is required to maintain a high velocity with acceleration.

In gasoline engines with throttle valves, the short distance from the throttle valve to the intake valve causes eddy currents to be negligible even at high flow rates.

However, as shown in the case of a diesel engine without a throttle valve, the vortex generation efficiency is much higher than that of a gasoline engine with a throttle valve because a sufficient distance from the intake valve to the air inlet is secured.

However, it is difficult to balance the amount of passing air at high speed and low speed.

Therefore, the flow rate and flow acceleration distance of the air passing through the intake pipe should be variable for low speed and high speed.

The economical speed RPM of a car is about halfway between high speed and low speed, which is when the efficiency of thermal expansion energy is the highest by balancing the flow rate with high vortex generation efficiency, the passing air volume, and the acceleration distance. The goal is to achieve energy efficiency close to economic speed at full RPM by varying the distance for low and high speeds.

In order to solve the structural problems of the four-stroke engine, it is natural to use the vortex described above (in the four-stroke engine), but the vortex-dependent engine using this vortex is not 100% mechanically accepted and its existence is scientifically recognized. It is underestimated.

As a result, automakers are now making cars using mechanical methods that eliminate vortices. For example, TURBO engines or air injection methods are common examples.

The turbo method is a typical compression ratio dependent engine in which the amount of air required for intake is forcibly supplied.

This method increases the thermal expansion pressure by forcibly supplying the intake air to increase the compression pressure regardless of the high speed and the low speed. There is no vortex generation, low energy efficiency, and it is difficult to fundamentally solve the mechanical stability, that is, the engine noise or vibration.

Next, it is a front injection type engine that puts the intake air inlet in parallel with the direction of vehicle travel so that the vehicle receives a head wind.

This method is to reduce the cross-sectional area of the air intake pipe to maintain a high flow rate in the air intake pipe at low speed, and to solve the shortage of air at high speed by the push-type method.

In this way, the effect of upwind is also irregular, and if the negative pressure of the intake pipe (from the throttle valve to the air inlet) is measured, the flow rate is closer to the turbo side than the vortex engine. Therefore, the pulsation phenomenon in the intake pipe (near the intake valve) is alleviated, so that vibration and noise are small, but the energy efficiency is low, which lowers the fuel consumption or the climbing ability.

Some automakers even apply this natural injection method to diesel engines (due to engine quietness), which needs to improve soot problems and energy efficiency.

The biggest disadvantage of the front injection method is that the air flow is assisted by the upwind (external force), so that the intake air does not have an acceleration (slow flow rate), so the amount of vortex generation is insignificant.

The present invention is to accelerate the mixing of light air through the air intake pipe and to achieve rapid mixing and combustion with continuous rotation by its inertia even at high pressure in the combustion chamber.

That is, by attaching the first vortex device to the inlet air intake duct inlet to cause the vortex phenomenon in the incoming air while adjusting the initial air inflow,

By constructing a supplementary air supply valve for high-speed inlet near the front of the air cleaner, the supply volume is supplemented with negative pressure in the intake pipe at the rear of the air cleaner, and

The second vortex device is formed at the inlet connected to the air intake pipe, and the inlet air is limited by the initial first vortex device due to the resistance, and the air passing through the air is accelerated by the suction force and the second vortex device The vortex is generated by the high speed even at low speed as the guideway.When the RPM is high speed, the negative pressure which is increased due to the lack of air volume at high speed in the intake air pipe is opened by the auxiliary air supply valve by opening the auxiliary air supply valve with the connection hose to intake external air. It is designed to make up for the inflow of air by supplying it into the conduit.

The present invention for achieving the above object comprises a first vortex device and a second vortex device formed at the inlet of the inlet and the air inlet air inlet pipe and the first vortex device configured to twist the semi-circular wing piece bent the end of the radial wing at the inlet of the supply air intake pipe By constructing the auxiliary air supply valve to be fastened, the auxiliary air supply valve is controlled by the negative pressure at the rear of the air cleaner so that the external air can be supplied. Solve the problem of harmful emissions such as engine output and soot by improving the combustion and energy efficiency

When the present invention is described in more detail by the accompanying drawings as follows.

1 is an explanatory view of the configuration of the present invention and Figure 2 is an enlarged view of the important part of the present invention and Figure 3 (a) (b) is a cross-sectional view illustrating the operation of the auxiliary air supply valve of the present invention and Figure 4 is The perspective view of the vortex apparatus is shown.

As shown in the drawing, the inlet 102 of the tip of the throttle valve 101 of the air intake pipe 10 connected to the cylinder 100 of the internal combustion engine consists of an air cleaner 103 and an initial intake pipe 11. Thus, the air drawn in is sucked into the initial intake pipe 11 and is supplied to the throttle valve and the cylinder 100 through the air cleaner 103 and the inlet 102 to form a conventional intake configuration.

According to the present invention, the first and second vortex devices 20 and 21 are fastened to the inlet of the initial intake pipe 11 and the inlet of the internet 101.

The vortex device constitutes a wing 24 in a radial shape within the tubular body 23 that exerts elasticity by the expansion and contraction of the cutout part 22, but the wing 24 is formed by twisting a curved semicircular wing piece. Thus, a plurality of pipe bodies 23 are formed.

In addition, the auxiliary air control valve 30 is fastened to the air cleaner 103 in front of the initial air intake pipe 11, and the control valve 30 is provided with a negative pressure formed in the air intake pipe 10 behind the air cleaner 103. ) To adjust.

The control valve 30 is an air injection hole in the shanghai dong when the on-off valve 34 elastically installed with the upper and lower springs 33 on the valve body 32 boring the air injection hole 31 on the main surface is elevated to negative pressure. The opening and closing amount of the 31 is adjusted to supply the injected air to the initial intake air pipe 11.

The control valve 30 forms a protruding supply pipe 35 to be fastened to the initial intake air inlet pipe 11, and a fastening pipe 36 is formed on the upper end of the valve body 32 to connect the air cleaner to the hose 37. The opening and closing valve 34 is vertically moved by the negative pressure generated in the intake pipe 10 by connecting to the intake pipe 10 at the rear side.

If described in more detail the effect of the present invention is configured as follows.

1 is an explanatory view of the configuration of the present invention and Figure 2 is an enlarged view of an important part of the present invention as shown in the air intake pipe to the internal combustion engine, such as a car air intake pipe is connected to the cylinder 100 as above The throttle valve 101 of FIG. 10, the inlet 102 of the front end, the air cleaner 103, and the initial intake air pipe 11 are comprised.

The first and second vortex devices 20 and 21 are fastened to the inlet and the inlet 101 of the initial intake pipe 11 of the known intake pipe.

In addition, the auxiliary air control valve 30 is fastened in front of the air cleaner 103 of the initial air intake pipe 11, and the control valve 30 is provided with a negative pressure formed in the air intake pipe 10 behind the air cleaner 103. ) To adjust.

That is, the protruding supply pipe 35 is fastened to the initial intake air pipe 11, and the valve body 32, the upper fastening pipe 36, is connected to the air intake pipe 10 at the rear of the air cleaner 103 with a connection hose 37. Will be connected.

At this time, the control valve 30 is more effective as the distance closer to the air cleaner 103, it is preferable to configure as close as possible.

That is, in the first vortex device 20 formed at the inlet of the initial intake pipe 11, the tubular body 23 exerting elasticity with the expansion and contraction of the cutout part 22 is fixed in the initial intake pipe 11, and the inside of the radiator is radiated. The wing 24, which is twisted in the form of amplification, is introduced at a high speed as the amount of inlet air decreases as the incoming air is controlled by resistance and is introduced while causing rotation by the guide by the twisted wing 24.

The inflow air passes through the air cleaner 103 and is supplied to the cylinder 100 of the internal combustion engine via the throttle valve 101.

This operation is limited by the resistance of the initial air regulator first vortex device 20, the air flow into the intake pipe is limited, and the air passing through the first vortex device 20 is accelerated by the suction force, so that the flow rate is high at low speed An excessive vortex is generated and a sufficient distance for accelerating the air to the inlet is also secured. Also, the inflow air flows into the cylinder 100 while being vortex, that is, rotated according to the secondary guidance from the second vortex device 21. In addition, since the combustion explosive is more effectively performed by increasing the mixing ratio of the fuel injected therein, the output of the fuel can be increased to reduce the fuel consumption and to prevent the smoke from being completely burned.

In addition, when the RPM moves at a high speed, the flow velocity in the intake pipe 10 is increased at a high speed. As a result, the negative pressure increases in the air intake pipe 10 due to the low supply amount of air due to the resistance by the first vortex device. As a result of detecting the lack of air, a negative pressure is transmitted to the connection hose 37 connected to the intake air pipe 10, and the negative pressure of the auxiliary air control valve 30 fastened to the front of the air cleaner 103 of the initial air intake air pipe 11. The on-off valve 34 is raised by the suction force.

That is, the opening / closing valve 34 elastically installed by the spring 33 in the valve body 32 by the suction force of negative pressure is elevated by the suction force of the upper portion and the air injection hole 31 formed on the main surface of the valve body 32 outside the opening / closing valve 34. ) To expand the development state.

Accordingly, a large amount of air flows into the initial air intake pipe 11 through the open air injection hole 31 by the negative pressure of the initial air intake pipe 11, thereby sufficiently replenishing the air insufficient in the air intake pipe 10.

Accordingly, while supplying sufficient air to the cylinder 100, the combustion rate is increased by mixing the feed fuel by the rotation by the first and second vortex devices 20 and 21, thereby preventing smoke from increasing output and full combustion. It is done.

In the present invention, the vortex-dependent engine is accelerated rapidly in the process of passing light air through the intake pipe, and continues to rotate due to its inertia at high pressure in the combustion chamber to improve the mixing rate. Provides concentration of spiritual power

Energy efficiency in a four-stroke engine can be exemplified by increasing the compression pressure by increasing the TURBO engine and the mixer, which increase the combustion pressure by increasing the compression ratio.

However, as environmental problems arise, it will be said that the method is unscientific in terms of efficacy.

Today's automobiles do not completely burn theoretical mix ratios because of structural shortcomings and fuel performance (which is less than octane or cetane expectation).

In this case, the exhaust gas is not completely burned according to the deterioration of the vehicle and the driving habits of the driver, and harmful emissions including smoke are generated.

Vortex-dependent engines are a method of using instantaneous concentration of force due to rapid combustion. Since the combustion of the four-stroke engine is combustion by the substitution reaction of diesel, gasoline, and LPG, there is a time difference from ignition to the end of combustion, and when this time difference is large, the power is dispersed and the energy efficiency decreases. Energy efficiency is increasing.

In the four-stroke process, the vortex-dependent engine of the present invention improves energy efficiency by rapidly burning air and fuel, unburned parts, and combustion parts by powerful vortices for each engine speed, and rapidly burning them. Is on purpose.

That is, the vortex-dependent engine is attached to the inlet air intake air inlet initial intake air pipe 11 as shown in the operating description of the first type of vortex device 20 for adjusting the air to adjust the initial air inflow and form a vortex Auxiliary air supply valve 30 was formed by a high speed air inlet device in front of the air cleaner (as close as possible), and a second vortex device 21 was formed at the inlet of the internet 102.

This limits the flow rate from the initial air inflow to resistance, providing sufficient distance for the increase of the vortex and the acceleration of air due to the rapid flow rate even at low engine speed due to the acceleration and vortex generation by the suction force. When the reinforcement is required, the auxiliary air supply valve 30 operated by the negative pressure in the intake airway pipe is opened to adjust the amount of air at a high speed to supply a large amount of air from the outside into the initial intake air pipe 11.

Accordingly, it is possible to solve the problem of harmful emissions such as engine output and soot by improving the energy efficiency by the complete combustion of fast combustion at low speed and high speed and the concentration of force by fast combustion. Passage flows in 2 ~ 3% less than other engines due to frictional resistance in the process of converting linear motion into circular motion.

For example, if A has a front injection MPI method and the mixing ratio is 16.25: 1, the fuel injection amount is automatically reduced by 2-3% because the air inflow is reduced by 2-3% when switching to the vortex-dependent engine. ), (FEED BACK effect)

In this case, the fuel saving effect can be obtained (for engines or diesel engines without a feedback system, the mixing ratio must be adjusted), and the portion where the combustion pressure is lowered is reinforcement of the lowered power by increasing energy efficiency by the focusing force of fast combustion. . In addition, increasing the energy efficiency by 1 ~ 2% due to the concentration of force due to rapid combustion will solve the emission problem and have a great effect on fuel saving, engine quietness and mechanical stability (vehicle life).

The present invention is designed to solve the pollution problem by investing the least amount of resources while reducing the smoke and harmful gas pollution by more than 90% and improving the performance of the vehicle by more than 120%.

The present invention accelerates rapidly in the process of light air passing through the intake air pipe, so that even in the high pressure of the combustion chamber, it is possible to achieve rapid mixing and combustion by continuous rotation by its inertia, but attaching the first vortex device to the inlet air inlet duct inlet. Vortex phenomena in the incoming air while controlling the initial air inflow,

By constructing the auxiliary air supply valve for high speed inlet near the front of the air cleaner, it regulates the supply amount by the negative pressure of the intake pipe at the rear of the air cleaner,

The second vortex device is formed at the inlet connected to the air intake pipe, and the inlet air is limited by the initial first vortex device due to the resistance, and the air passing through the air is accelerated by the suction force and the first vortex device is The vortex is generated by the high speed even at low speed as the guideway. When the RPM is high, the flow rate in the intake pipe is high and the negative pressure is increased due to lack of air volume.The negative pressure is opened by the connection hose to open the auxiliary air supply valve. By supplying air into the air intake pipe, the amount of inlet air is fully replenished by providing the required air volume at low and high speeds, and the mixing rate by vortex is improved to increase the power output and save fuel by rapid combustion. Simple design that can be mass-produced at low cost .
