National VI Muffler It is a key component of the automotive exhaust system, mainly used to reduce exhaust noise and purify exhaust pollutants, while adapting to the strict requirements of the National VI emission standards. Specific functions are as follows:

1. Noise Reduction Function Through the complex internal cavity structure (such as expansion chambers, resonance chambers) and sound-absorbing materials, the high-speed, high-pressure exhaust gas flow impacts, reflects, and rubs against each other during the flow process, consuming sound energy, thereby significantly reducing the high-frequency, harsh noise generated by the engine exhaust and reducing noise pollution to the environment and human body.

2. Exhaust Purification Function

National VI mufflers usually integrate or cooperate with post-treatment systems (such as DOC oxidation catalysts, DPF particulate traps, SCR selective catalytic reduction systems, etc.) to further process pollutants in the exhaust.
