motorcycle exhaust pipe

Abstract

The invention discloses a motorcycle exhaust pipe. A muffler is arranged outside the exhaust pipe. Filters are arranged in the exhaust pipe and comprise the pipe wall filter and the outlet end filter. The pipe wall filter is arranged in the exhaust pipe and connected to the inner wall of the exhaust pipe and comprises a supporting net, a filter core, a filter net and a filter layer from outside to inside. The outlet end filter is arranged at the outlet end of the exhaust pipe. The inlet end of the exhaust pipe is in threaded connection with the exhaust port of an engine air cylinder. Fastening devices are arranged at the inlet end of the exhaust pipe and the exhaust port of the engine air cylinder. A silencer is further arranged in the exhaust pipe to reduce noise pollution in cities. Through the double filters, the purification efficiency of motorcycle tail gas can be improved, and the filter effect is good.

Description

technical field [0001] The invention relates to the field of motorcycle accessories, in particular to a motorcycle exhaust pipe. Background technique [0002] Most of the existing motorcycle exhaust pipes are hollow cylinders with built-in mufflers. The front nozzle of the exhaust pipe is connected to the engine exhaust port. release. But the existing exhaust pipe is made of stainless steel metal material, and most of them are single-layer pipe structure. When the motorcycle is running, the gas discharged from the engine is conducted through the pipe wall of the stainless steel exhaust pipe to make its surface temperature very high, which will Man-made burns. [0003] The motorcycle exhaust pipe is an important part of the motorcycle. The main function of the exhaust pipe is to discharge the exhaust gas after the combustion of the engine. The exhaust gas emitted by motorcycles contains a large amount of harmful carbon particles and impurities, which has caused serious pol...

AI Technical Summary

Problems solved by technology

The exhaust gas emitted by motorcycles contains a large amount of harmful carbon particles and impurities, which has caused serious pollution to the environment. If it is not disposed of in time, it will bring great harm to people's life and health as time goes by.

[0004] At the same time, most of the exhaust pipes are made of aluminum, but the coefficient of thermal expansion of aluminum is relatively large, coupled with the vibration of the exhaust pipe, and the expansion of the aluminum material of the exhaust pipe, so the bolts and nuts that fix the exhaust pipe will not work properly when the engine is working. Looseness will easily appear in the middle of the exhaust pipe, and the noise will increase as the exhaust pipe becomes loose
