Automobile exhaust bellows, also known as automobile exhaust hose, is installed in the exhaust pipe between the engine exhaust branch pipe and muffler, which makes the whole exhaust system flexibly connected, thus playing the role of vibration and noise reduction, convenient installation and prolonging the service life of the exhaust muffler system.
It is mainly used in light cars, mini-cars and buses. Its structure is a double-layer corrugated pipe, covered with steel wire mesh sleeve, and the straight edge sections at both ends are covered with snap rings. In order to make the noise elimination effect better, an expansion joint or a net sleeve can be arranged inside the bellows. Material: The main material is stainless steel SUS304, and the sleeve and nozzle can be made of stainless steel or aluminized steel.
function
As far as the function of automobile exhaust pipe on automobile fuselage is concerned, it plays a role in reducing vibration and noise and prolonging the life of exhaust muffler system. The main material of exhaust pipe is stainless steel.
For ordinary cars, because the exhaust gas from the car leaves the engine under great pressure, the noise may make people feel crazy. At this time, the exhaust pipe of the car plays the main role of silencing, and the muffler is installed inside, which greatly reduces the noise of the car.
Its main working principle is to split the airflow through multiple channels. These lobes just collide with each other to gradually reduce the speed of air flow, and so on. Finally, the exhaust gas is discharged through the exhaust pipe of the car, which reduces the noise! So as to achieve the effect of reducing the daily automobile noise.
