Abstract

The invention discloses an automobile exhaust device which comprises an engine exhaust pipe connector, a return pressure cylinder body, a three-way catalytic cylinder body, a first three-way connection pipe, a straight through exhaust pipe, a silencing pipe, a second three-way pipe, an exhaust valve and an exhaust pipe. Compared with the prior art, the three-way catalytic cylinder body is arrangedat the front end of the silencing pipe, and therefore pollution is reduced. In addition, two output paths are arranged, when large-power operation is needed, the exhaust valve is opened through electric control, engine exhaust is smooth, and engine power is improved; and during engine stable operation, the exhaust valve is closed, therefore, the silencing pipe achieves a silencing effect, and theapplication and popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile exhaust device. Background technique [0002] The automobile exhaust system mainly discharges the exhaust gas from the engine, and at the same time reduces the pollution of the exhaust gas and reduces the noise. Automobile exhaust systems are mainly used in light vehicles, mini-cars, passenger cars, motorcycles and other motor vehicles. [0003] An automobile exhaust system refers to a system that collects and emits exhaust gas, and generally consists of an exhaust manifold, an exhaust pipe, a catalytic converter, an exhaust temperature sensor, an automobile muffler, and an exhaust tailpipe. [0004] In the prior art, most of the exhaust devices of automobiles are only for noise reduction, but when high-power operation is required, the exhaust is subjected to the sound of noise reduction and the engine power is reduced. Therefore, there is room for improvement....
