Description

Exhaust bucket of a car using the flowing of air}

The present invention relates to an exhaust box of a vehicle using air flow, and more particularly, to an exhaust box of a vehicle using air flow to improve the exhaust performance of the vehicle by using the air flow generated according to the driving of the vehicle. will be.

In general, automobiles are an important means of transportation on the ground and are an indispensable vehicle in today's modern society.

These automobiles are usually equipped with a gasoline or diesel engine, which is a kind of internal combustion engine, and the engines of the various types, in addition to the engine body including cylinders and pistons, provide an intake system for supplying fuel and air to the engine and exhausted combustion exhaust gas. An exhaust system.

That is, a description of the operation relationship, for example a typical automotive internal combustion engine of four-stroke cycle consisting of suction, compression, expansion, exhaust, the mixer is sucked into the cylinder by the lowering of the piston, the mixer is compressed by the lifting of the piston In addition, the ignition causes the mixer to explode and expand the hot / high pressure combustion gas to lower the piston, and the reaction force causes the piston to rise again to discharge the combustion gas out of the cylinder.

At this time, the intake machine is to supply a mixer to the cylinder, the exhaust system is configured to discharge the exhaust gas so that a new mixer is supplied into the cylinder.

In recent years, various attempts have been made to improve the energy efficiency and performance of such internal combustion engines. Thus, compressors are installed in DOHC type engines or intake machines that increase the number of suction valves to increase the suction amount of the mixer sucked into the cylinder. A supercharged engine has been developed, and in addition, engines for cooling the mixer by installing an intercooler have been developed and used to improve the filling rate of the inhaled mixer.

However, these conventional improvement methods are all intended to increase only the suction amount of the mixer which is installed in the intake machine and sucked into the cylinder, and does not consider the smooth exhaust of the combustion gas through the exhaust system. Not only does it shorten the life of the internal combustion engine, but it also interrupts the flow of the mixer where the high-pressure combustion gas remaining in the exhaust system is sucked, thereby lowering the engine output and facilitating the suction. There has been a problem that a compressor or an intercooler of a capacity must be installed.

Moreover, in recent years, environmental problems with air pollution and noise have been highlighted, and various filters, catalyst devices, silencers, etc. are attached to the exhaust system, making it difficult to smoothly exhaust the combustion gas, and the performance of the engine, such as energy efficiency and output, has been greatly reduced. There have been many problems such as illegally modifying or removing the silencer to improve the exhaust performance of the engine.

In addition, the conventional exhaust gas outlet is generally a cross-sectional shape of the pipe, so the exhaust gas is concentrated in one place, and the high exhaust density of the exhaust gas causes dust or winter mist to obstruct the rear view field, and causes a lot of noise. There was this.

An object of the present invention for solving the above problems is to improve the exhaust performance and energy efficiency of the engine by inducing the smooth exhaust of the combustion gas by using the air flow naturally occurring during driving of the vehicle without a separate drive device To improve the durability of the parts by helping the functions of the various components installed in the intake and exhaust system, and to improve the rear view by distributing the exhaust gas, to provide a car exhaust box using the air flow to reduce noise have.
