Description

Automobile exhaust vent {A automobile combustion gas guide apparatus}

The present invention relates to an automobile exhaust port, and more particularly, by providing a driving means in the exhaust port to discharge the flow of exhaust gas discharged from the engine at a high speed to lower the pressure in the pipe, thereby increasing the amount of intake air The present invention relates to an automobile exhaust port, which enables the output of an engine to be improved, to reduce the emission of soot through the complete combustion of fuel, and to save fuel.

In general, automobiles are driven by inhaling and compressing a mixer mixed with air at a proper ratio, and then driving the linear motion generated by ignition and expansion through a driving force converted into a rotational motion with torque by using a connecting rod and a crank. It becomes possible.

The exhaust gas generated by ignition is collected in one place through an exhaust manifold provided in the engine, and then passed through a catalytic converter, and carbon monoxide, hydrocarbons, and nitrogen oxides are purified through a catalyst, and reduced to an exhaust pipe. While passing through the muffler provided in the discharge pipe, the pressure is lowered through a plurality of expansion processes, and discharged at a pressure almost equal to atmospheric pressure through the exhaust port provided at the end of the discharge pipe.

However, as the exhaust gas passing through the exhaust manifold and the converter passes through the muffler provided on the discharge pipe, the pressure and the flow rate are lowered to act as the discharge resistance, thereby reducing the output of the engine.

In addition, in the case of the conventional exhaust port, the exhaust gas is stagnated in the exhaust port and the exhaust gas is constantly in the combustion chamber of the internal combustion engine due to the stagnant exhaust gas. There was a problem of this deterioration.

In addition, as the exhaust gas remains, non-combustion continues to occur due to unburned gas in the combustion chamber in the internal combustion engine, and the exhaust gas is discharged into the air in a state in which the exhaust gas contains a large amount of harmful gases, thereby causing pollution. .

Accordingly, in order to solve the above problems, conventionally, a structure in which the vortex generating means for generating the vortex when the exhaust gas is discharged is fixed inside the exhaust pipe is provided.

However, such a structure that allows the exhaust gas to form a vortex is due to the weak pressure lowered due to the lower pressure in the course of passing the exhaust manifold provided on the exhaust pipe and the catalytic converter and muffler.

When the vehicle is operated after the exhaust port 100 is installed in the exhaust pipe 10 of the vehicle, the engine of the vehicle is operated, and the mixture of fuel and air is compressed and exploded in the engine to generate driving force of the vehicle and fuel. The exhaust gas generated by combustion of exhaust gas from the exhaust manifold passes through a catalytic converter (not shown), and harmful substances such as carbon monoxide, hydrocarbons, and nitrogen oxides are reduced by the catalyst, and the exhaust gas exits the exhaust pipe 10. Supplied to 100.

At this time, when the harmful substance is supplied to the exhaust port 100 through the discharge pipe 10, the exhaust gas discharged from the discharge pipe 10 is rotated in one direction by the guidance of the vortex generator 140 to form a vortex Will be discharged.

That is, the exhaust gas discharged through the discharge pipe 10 is rotated in one direction by the screw-shaped wing 144 of the vortex generator 140 so that the vortex is naturally generated, and the vortex generator 140 By exhausting the exhaust gas to form a vortex by the exhaust flow of the exhaust gas is faster it can be discharged more effectively.

In addition, the exhaust gas remaining in the exhaust port 100 and flowed back to the through hole 132 of the inner tube 140 through a space formed in the inner circumferential surface of the main body 110 and the inner tube 130 and the outer circumferential surface. The exhaust gas is discharged to the outside of the exhaust port 100 again by the vortices generated by the vortex generating unit 140 to completely discharge the exhaust gas that has not been discharged to the outside through the inside of the exhaust port 100. You can do it.

Here, the through hole 132 is preferably formed to be close to the forward direction in which the guide member 142 of the vortex generating unit 140, that is, the discharge pipe 10 direction.

Therefore, the exhaust gas generated in the engine and supplied to the exhaust port 100 through the discharge pipe 10 is discharged while the vortex is formed by the guide of the wing 144 of the vortex generator 140 and the flow rate of the exhaust gas. By allowing the exhaust gas to flow at high speed and allowing it to be discharged into the air, the pressure in the pipe is lowered to increase the amount of intake air, thereby improving the engine output and exhausting the exhaust emissions through the complete combustion of the fuel. Can be reduced.

In addition, the exhaust gas remains in the exhaust port 100 so that the non-combusted gas is continuously generated by the unburned gas in the combustion chamber of the engine so that the exhaust gas discharged into the air in a state in which the exhaust gas contains a large amount of harmful gas is completely burned. This can be solved.
