Description

Energy-efficient device for internal combustion engine using exhaust venturi tube. {PROMOTE AN EFFICIENCY OF AN INTERNAL COMBUSTION ENGINE BY THE EXHAUST VENTURI}

The present invention is a device for lowering the exhaust pressure in order to increase the combustion efficiency of the internal combustion engine, the apparatus for attaching the exhaust venturi tube using the flow of air naturally generated when driving the vehicle to the vehicle exhaust port. As a method, the following method was generally used.

1, how to increase fuel economy by increasing the suction pressure.

2, how to increase fuel economy by lowering the intake temperature.

3, to improve fuel efficiency by increasing the efficiency of mixing air and fuel.

However, the above methods have a problem in that the cost increases or the structure is complicated by attaching a device that realizes the above object to any part of the engine or installing a separate device inside the engine.

Accordingly, the present invention implements the venturi tube principle (figure 5) for the vehicle exhaust pipe so as to realize an increase in combustion efficiency of the internal combustion engine, and forms a vacuum pressure at the exhaust port part by using air flow naturally generated while driving the vehicle. It is a device designed to increase the combustion efficiency of the internal combustion engine (especially the emission effect of the unexhausted residual gas in the combustion chamber: the scavenging efficiency) by forcibly inducing and exhausting the exhaust gas in the exhaust port.

D. Vacuum Generation Site

If the structure of the exhaust venturi tube as described above in detail,

The exhaust venturi tube has a convoluted cylindrical outer case (3) structure having a suction port and an exhaust port, and a vacuum derivative (4) having a conical structure at both sides in the inner center thereof is radially attached by a plurality of supports (4), and is pipe-like. The connecting pipe (2) is located in the same direction as the vacuum inductor (4), a portion of the body is inserted into the outer case (3), a part of the structure having a shape that protrudes to the outside, a plurality of connecting members (8 Has a structure radially fixed to the outer case (3) by

When the air introduced into the exhaust venturi tube having the structure described above forms a vacuum pressure in the exhaust port portion by the venturi principle, the operation of forcibly inducing exhaust gas is as follows.

As shown in FIG. 2, air A naturally generated by driving a vehicle is introduced into the corrugated outer case 3 as an arrow.

At this time, the forced-intake air (A) passes through the vacuum inductor (4) while passing through the portion (B2) of which the area is gradually narrowed (B2) in the portion (B1) having a wide cross section inside the outer case (3) ) Speeds up rapidly,

At the same time, a vacuum force is generated at the lower portion of the suction rear surface B2, that is, the portion D of the pipe-shaped connecting pipe 2, and the exhaust gas C proceeds to the solid line portion. By the induction discharge of the inlet air (A) by the exhaust gas (C) is combined is discharged through the outlet (7).

In addition, the vacuum derivative (4) formed therein induces air (A) to induce the flow of the exhaust gas (C), and at the same time induces the vacuum generation of the vacuum generating portion (D) of the front portion of the conical structure of the front portion.

The above operation is to implement the exhaust venturi tube for attaching the vehicle exhaust vent as shown in Figure 5,

The forced intake air of FIG. 5 moves from the large cross section (10) to the narrower (9) section, increasing the velocity of the air, and at the same time generating a vacuum force in the (E) section of the intermediate connecting pipe to induce or The same principle as the forced induction discharge of the gas (12).

By using the air generated naturally during vehicle driving, the vacuum pressure is formed at the exhaust port portion, and the exhaust gas is forcibly induced and discharged to increase the combustion efficiency of the internal combustion engine.
