Abstract

The invention provides an automobile exhaust gas emission system with a damping device. The automobile exhaust gas emission system comprises a gas inlet pipe, a middle pipe body and a gas outlet pipe. The gas inlet pipe is connected with the gas outlet pipe through the middle pipe body. The damping device is arranged outside the gas outlet pipe. The gas inlet pipe extends into the middle pipe body, and gas outlet holes are formed in the side wall of the part, extending into the middle pipe body, of the gas inlet pipe. A plurality of filtering devices located in the middle pipe body are arranged on the right side of the gas inlet pipe. Each filtering device comprises a primary filtering piece, wherein first flow equalizing baffle pieces which are symmetrical up and down are arranged on the right side of the primary filtering piece, a second flow equalizing baffle piece located between the first flow equalizing baffle pieces is arranged on the right sides of the first flow equalizing baffle pieces, and a three-way catalyst is arranged on the right side of the second flow equalizing baffle piece. The lower end of the right side of the middle pipe body is connected with the gas outlet pipe, a secondary filtering piece is arranged in the gas outlet pipe, a water outlet groove is formed in the lower end face in the gas outlet pipe, and water outlet holes are formed in the bottom of the water outlet groove. The automobile exhaust gas emission system has the beneficial effects of being simple in structure and capable of lowering noise and reducing pollution.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to an automobile exhaust emission system with a shock absorbing device. Background technique [0002] The exhaust pipe is a common part on the car, which is used to discharge the exhaust gas from the engine. Most of the traditional exhaust pipes discharge the gas directly, so the untreated exhaust exhaust device will cause air pollution and damage the environment. Contents of the invention [0003] The object of the present invention is to provide an automobile tail gas emission device with simple structure, reduced noise and reduced pollution. [0004] The technical solution of the present invention is: an automobile exhaust emission system with a shock absorbing device, including an air intake pipe, an intermediate pipe body, and an air outlet pipe. shock absorber, [0005] The air inlet pipe extends into the middle pipe body, and part of the side wall extending into the ...
