The present invention relates to an apparatus for increasing the output of an internal combustion engine and at the same time suppressing harmful components of exhaust gas.

The method of incorporating secondary air into the fuel mixer of the internal combustion engine to achieve complete combustion of the fuel has been conventionally carried out, but it has not been achieved until the output performance of the internal combustion engine has been improved. It is theoretically clear that it cannot be to reduce (NOx).

On the other hand, incorporating methanol into the fuel solution is known to have an effect as an anti-noxing agent, but it is necessary to mix much methanol of about 20% or more.

An object of the present invention is to increase the output of the internal combustion engine by automatically adjusting the amount of alcohol vapor and water vapor containing secondary air, such as air supplied secondary to the internal combustion engine according to the operating state of the internal combustion engine It is to provide a device that can reduce the exhaust gas.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. The apparatus of the present invention in FIG. It consists of an injector (3) attached to the tank (1) and an adjustment valve mechanism (4).

As shown in FIG. 1 and FIG. 2, the adjustment valve mechanism 4 inserts the valve piston 7 in the cylinder chamber 6 of the cylindrical cylinder 5 with one end closed in an activatable manner.

A small hole (hereinafter referred to as a small diameter portion) 8 is provided on the left side of the cylinder chamber 6 so that the limiting portion 9 formed by the small diameter portion 8 becomes the left stopper of the valve piston 7.

The valve piston 7 is deflected to the right via the spring 10 between the bottom of the small diameter portion 8 and the left end of the valve piston 7. At the right end of the cylinder 5, a socket 11 having a through hole 12 is inserted in the axial direction.

The inner end of the socket 11 is the right stopper of the valve piston 7. An air filter 13 is attached to the right end of the socket 11. In the substantially center portion of the valve piston 7, a main tool 14 is provided, and a passage 15 communicating with the right end surface of the main tool 14 and the valve piston 7 is provided.

Three passages are provided in the cylinder 5. That is, when the passage 16 and the valve piston 7 leading to the small diameter portion 8 forming the left side of the cylinder chamber 6 move to the left end, they are in communication with the main tool 14, and when moved to the right, the valve piston 7 If the passage 17 and the valve piston 7 blocked by the peripheral wall of the valve 18 are moved to the right end, the passage 18 communicates with the main tool 14, and when moved to the left, the passage 18 is blocked by the peripheral wall of the valve piston 7. to be. The passage 16 communicates with the space of the outer tank 1 via the valve piston operation passage 19, and the passage 17 communicates with the secondary mixer supply passage 21 via the control valve 20. .

And the passage 18 communicates with the injector 3 attached in the outer tank 1. A passage 22 is interposed in the middle of the secondary mixer supply passage 21 to communicate with the upper surface of the outer tank 1.

The injector 3 attached to the outer tank 1 includes an air introduction pipe 23 and an injection pipe 24, and the air introduction pipe 23 and the injection pipe 24 communicate with each other via the hollow member 25. It is.

An introduction port 26 for introducing a liquid in the outer tank 1 is provided at the bottom of the hollow member 25, and an injection port 27 is also provided at the upper end of the injector 24. The injection pipe 24 and the hollow member 25 may be omitted.

The inner tank (2) is fixed in the outer tank (1), one end of which is attached to the alcohol vapor supply pipe (28) which opens at one end into the outer tank (1) and the other end is in communication with the tank (2). .

Inner tank (2) is attached to the injection pipe 29 for supplying the alcoholic liquid, one end of the injection pipe 29 protrudes to the upper surface of the outer tank (1) to be opened and closed by a suitable lid have.

Reference numeral 30 is a lid for blocking the liquid inlet of the outer tank (1). The apparatus of the present invention is configured as described above, and in the case of using the apparatus, the secondary mixer supply passage 21 is connected by a suitable pipe just below the throttle valve 32 in the carburetor 31 of an internal combustion engine such as an automobile engine. In communication with the air flow path (see FIG. 4).

Reference numeral 34 in the drawing denotes a fuel injection nozzle, and reference numeral 33 denotes a manifold communicating with the cylinder chamber of the engine.

Into the inner tank (2) is injected a solution of isopropyl alcohol and acetone in an alcohol type liquid such as methyl alcohol, or a solution in which only one of isopropyl alcohol and acetone is mixed in methyl alcohol, and water is injected into the outer tank (1). A small amount of alcohol may be mixed with the foreign material.

If the internal combustion engine, such as an automobile engine, is idling or is operating at low speed, the throttle valve 32 is slightly opened, and the negative pressure in the manifold 33 is large.

This negative pressure is moved to the position of FIG. 5 by actuating the valve piston 7 via the passages 21, 22 and 19 and the passage 16. As shown in FIG.

As a result, the passage 18 leading to the injector 3 is blocked by the circumferential wall of the valve piston, and the passage 17 communicates with the main mouth 14 of the valve piston. Since the main tool 14 communicates with the outside air via the passage 15, a lot of air is introduced into the passage 21 by the negative pressure.

On the other hand, since the passages 21 and 22 communicate with the outer tank 1, the air introduced into the passage 21 is mixed with the fuel mixer in the carburetor 31 while containing water vapor and alcohol vapor in the outer tank 1. Is supplied to the engine. As described above, when the throttle valve 32 is slightly opened, the amount of air in the fuel mixer is insufficient and the fuel date becomes coarse. Therefore, it is extremely effective to send a large amount of air to the secondary to completely burn the fuel. This results in reduction of carbon monoxide (CO) and hydrocarbons (HC) in the fuel, and at the same time saves fuel.

Next, when the vehicle is driven at high speed, the throttle valve 32 is largely opened, so that a large amount of fuel mixture containing sufficient air is sent from the carburetor to the engine.

At this time, since the negative pressure in the manifold 33 becomes small, as the spring 10 moves the valve piston 7 to the position as shown in FIG. 4, the passage 17 is blocked and at the same time the passage 18 is closed. It communicates with the main tool 14 of the valve piston. As a result, air is introduced into the injector 3.

In the injection pipe (24) of the injector (3), a mole in the outer tank (1) is introduced from the inlet port (26) to be ejected from the outlet port (27), such as air introduced from the inlet pipe (23), thereby promoting the evaporation of water. As a result, the content of water vapor is relatively high, and air containing alcohol vapor passes through the passage 22 and the passage 21 and is added to the fuel mixer.

As described above, since the fuel mixer contains sufficient air, it is hardly necessary to supply air secondaryly, but the amount of nitrogen oxides (NOx) in the exhaust gas increases because the fuel is completely burned at a high temperature. The supply of secondary steam at this time is extremely effective for lowering the combustion temperature and the combustion rate.

Meanwhile, alcohol medium is an anti-knock agent, which prevents knocking and increases output, thereby reducing fuel consumption. The reason why the tank containing the alcohol type liquid and the water and the alcohol type liquid are separated and stored is that the content rate of the alcohol vapor is constantly stabilized. For example, when a single tank is used to inject water into a mixture of alcoholic substances, the first alcohol vapor concentration is high and the next concentration drops, so that no stable effect can be obtained.

In the latter case, it is uneconomical due to excessive evaporation of alcoholic liquids.

As a result of attaching the present invention to Mitsubishi Lancer A-73 (1,590 cc of exhaust from Mitsubishi Motor Corporation), the following results were obtained.

This inspection was carried out by the Japan Automobile Inspection Association.

Average emission reduction rate

Fuel consumption was reduced by about 10%.

As described above, according to the present invention, the output performance of the internal combustion engine can be increased, fuel can be saved, and exhaust gas can be reduced.
