Why is the exhaust pipe of Buick LaCrosse so loud?
Due to too much carbon and dirt in the air inlet, the cross-sectional area of the air passage changes, which makes the control unit unable to accurately control the idle intake air volume, resulting in too rich or too thin air mixture, abnormal combustion or engine jitter, and even unable to start after starting. It is best to check the intake valve and combustion chamber for excessive carbon deposition with an endoscope.
Exhaust pipe description
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.
