Automobile exhaust gas vent pipe

Abstract

The invention belongs to the technical field of automobile accessories, and particularly relates to an automobile exhaust gas vent pipe. The automobile exhaust gas vent pipe comprises gas inlet pipes, gas vent pipe bodies and a gas outlet pipe. The gas inlet pipes include the left gas inlet pipe and the right gas inlet pipe. The gas vent pipe bodies include the left gas vent pipe body and the right gas vent pipe body. A communicating pipe is arranged in the middles of the left gas vent pipe body and the right gas vent pipe body. The portions, below the communicating pipe, of the left gas vent pipe body and the right gas vent pipe body are each provided with a filter device, a three-way catalyst, a silencer and a filter layer in sequence. The gas outlet pipe is located below the filter layers. The automobile exhaust gas vent pipe has the beneficial effects that gas in the left gas vent pipe body and gas in the right gas vent pipe body can be circulated through the communicating pipe, and therefore return pressure is balanced and no pollution is caused.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to an auto exhaust pipe. Background technique [0002] The exhaust pipe is a very common exhaust component on the car. Its air inlet is connected with the gas exhausted from the engine and discharged from the outlet of the exhaust pipe. Existing automobile exhaust pipes usually include a left exhaust pipe and a right exhaust pipe, both of which are independent, and generally each has four air inlets for respectively receiving gas discharged from the engine. The pressure of the gas discharged from the engine is usually the same, but when passing through the two exhaust pipes, due to the difference in design between the two, it will cause different back pressures when the gas circulates in the two exhaust pipes. The air pressure imbalance caused by the back pressure will in turn affect the exhaust condition and power performance of the engine, and even affect the runni...

Problems solved by technology

The pressure of the gas discharged from the engine is usually the same, but when passing through the two exhaust pipes, due to the difference in design between the two, it will cause different back pressures when the gas circulates in the two exhaust pipes. The back pressure causes the air pressure to be unbalanced, which will in turn affect the exhaust condition and power performance of the engine, and even affect the running performance of the entire car.
