What is the structure of the China VI exhaust pipe?

[JeffreyAnn]

China VI exhaust pipe is an exhaust pipeline system for light trucks. It has a catalytic converter at the front, equipped with a differential pressure pipe connected to a sensor, and a main muffler at the rear, which is suspended from the frame via hooks and rubber hangers. The exhaust pipe primarily serves to reduce vibration and noise (muffling). During driving, the exhaust gas exits the engine under high pressure, generating significant noise. The muffler inside the exhaust pipe helps to reduce this noise to some extent. The exhaust pipe also plays a role in reducing harmful gas pollution. The automotive exhaust system includes a "three-way catalytic converter" device, which converts harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides emitted by the vehicle into harmless carbon dioxide, water, and nitrogen through oxidation-reduction reactions. This purifies the vehicle's exhaust and reduces air pollution.
