During car maintenance, most car owners know that the three oil filters need to be replaced regularly. If they are a little aware of car maintenance, they will also clean the throttle

First, we need to understand what the exhaust pipe is for. The work of the engine needs to inhale air, and the exhaust gas after the work of the engine needs to be discharged.

As for the maintenance method of exhaust pipe, it is best to pay attention to the following points:

Automobile exhaust system includes exhaust manifold, oxygen sensor, three-way catalytic converter, front and rear muffler, etc. The normal operation of the whole system is related to the normal operation of the engine

The three-way catalyst is similar to a muffler. Its appearance is made of double-layer stainless steel plate. Insulation material asbestos fiber felt is installed in the interlayer.

With the development of cars and electric vehicles, the motorcycle market is much smaller than in the past, and many cities have anti motorcycle measures, which has put more pressure on the motorcycle market.

Most of the dripping water from the exhaust pipe of the car occurs in new cars. Many car owners will be surprised when they find it. Do they think there is something wrong?
