Problems solved by technology

[0002] Automobiles are already the most common means of transportation for people, and automobile exhaust pipes are an important part of the whole vehicle; with the increase of the emission limits of automobiles in the whole country and abroad, the corresponding after-treatment systems are gradually added to automobile exhaust pipes; The exhaust pipe is connected to the engine assembly. When the engine is working, resonance occurs between the engine and the exhaust pipe of the automobile, which causes the exhaust pipe of the automobile to vibrate, accompanied by resonance noise, which not only affects the life of the exhaust pipe of the automobile but also increases the The noise of the whole vehicle and poor user experience; therefore, a car exhaust pipe is needed

Abstract

The invention relates to an automobile exhaust pipe. The automobile exhaust pipe comprises a connecting piece. The connecting piece is internally provided with a fixing ring. The lower part of the connecting piece is connected with a front exhaust pipe body. The tail of the front exhaust pipe body is provided with a three-way catalyst. A middle exhaust pipe body is arranged behind the three-way catalyst. The inner wall of the front exhaust pipe body and the inner wall of the middle exhaust pipe body are each sequentially provided with a thermal-protective coating and a noise reduction coatingfrom interior to exterior. The tail of the middle exhaust pipe body is provided with a particle collecting device. A rear exhaust pipe body is arranged behind the particle collecting device. The innerwall of the rear exhaust pipe body is provided with a noise reduction coating. The middle of the rear exhaust pipe body is provided with a silencer. The tail of the rear exhaust pipe body is providedwith an exhaust port. The inner side of the exhaust port is provided with a filter net. A shock absorber is arranged below the three-way catalyst, and a shock absorber is arranged above the particlecollecting device. The shock absorbers are connected with extension pipes, and the extension pipes are attached to the surface of the middle exhaust pipe body, the surface of the particle collecting device, the surface of the rear exhaust pipe body and the surface of the silencer. The automobile exhaust pipe has the advantages of being good in cleaning effect, capable of carrying out damping and absorbing noise and long in service life.
