What is the function of automobile export control
The main functions of automobile exhaust system include emission of exhaust gas from engine work, reduction of exhaust gas pollution and reduction of noise. The exhaust system consists of an exhaust manifold, exhaust pipe, catalytic converter, exhaust temperature sensor, automobile muffler and exhaust tailpipe, etc. .
Specifically, the role of the automotive exhaust system includes:
Exhaust gas : the exhaust gas generated during engine operation is discharged through the exhaust system to keep the engine running normally .
reduce pollution : catalytic converters can change harmful substances in waste gas into harmless ones, such as carbon monoxide, hydrocarbons and nitrogen oxides into carbon dioxide, water and nitrogen, thus reducing the pollution to the environment .
Noise reduction : mufflers are included in the exhaust system to reduce exhaust noise and improve driving comfort .
reduced vibration : The structure of the exhaust pipe is designed to dissipate engine vibration and reduce vehicle vibration .
control power output : the design of the exhaust system can affect the power output curve of the engine, thereby adjusting the driving experience .
In addition, the automotive exhaust system also includes some specific components and functions:
Exhaust manifold : the exhaust gas of each cylinder is discharged centrally to avoid cylinder interference with each other and improve exhaust efficiency .
exhaust pipe : connected to the exhaust manifold and muffler, play the role of shock absorption and noise reduction and convenient installation .
catalytic converter : installed in the exhaust system, capable of converting harmful gases into harmless substances .
muffler : reduces exhaust noise and improves driving comfort .
exhaust tailpipe : discharge the purified waste gas and complete the last step of the exhaust system .
