Abstract

The invention relates to an exhaust pipe for an automobile. The exhaust pipe for the automobile is characterized by comprising an exhaust pipe body provided with an exhaust channel; the exhaust pipe body comprises an exhaust main pipe, wherein one end of the exhaust main pipe is used for being communicated with an automobile exhaust port, and the other end of the exhaust main pipe is provided with two or more exhaust branch pipes in a divided mode; one end of each exhaust branch pipe is communicated with the exhaust main pipe, and the other end of each exhaust branch pipe extends in the direction away from the exhaust main pipe; the three exhaust branch pipes are located on the same plane as the exhaust main pipe, and the exhaust branch pipe in the middle is coaxial with the exhaust main pipe; the joints, in the direction of air flow in the exhaust channel, between every two adjacent exhaust branch pipes are provided with dividing baffle sheets respectively in a protruding mode. The exhaust pipe for the automobile has the advantages that the tail gas exhaust noise of an automobile exhaust system can be lowered, the structure is simple, manufacturing and processing are easy, and a muffler does not need to be mounted compared with the prior art.

Description

technical field [0001] The invention relates to an exhaust pipe for automobiles. Background technique [0002] In recent years, urban motor vehicles have grown rapidly, and the accompanying phenomenon of traffic noise pollution has become increasingly prominent. The biggest hazard of automobiles to environmental protection is noise pollution. The survey shows that motor vehicle noise accounts for 85.5% of urban traffic noise. The development of energy saving and emission reduction requires automobiles to reduce noise and save energy consumption. The main noise of the car comes from the exhaust system of the car, that is, the noise of the exhaust emission of the car. In order to reduce the noise of the exhaust emission of the car and meet the requirements of automobile environmental protection, the traditional car exhaust system realizes noise reduction by installing a muffler, but the muffler The structure is complex and the installation is inconvenient. Contents of the i...
