Origin:

The function of the Discharge Muffler from China manufacturer is to reduce the exhaust noise by gradually reducing the exhaust pressure and attenuating the pulsation of the exhaust pressure.

The exhaust pressure of the engine is about 0.3~0.5MPa, and the temperature is about 500~700℃, which indicates that the exhaust gas has a certain amount of energy. At the same time, due to the intermittent nature of the exhaust gas, a pulsation of the exhaust gas pressure is caused in the exhaust pipe. If the engine exhaust gas is directly discharged into the atmosphere, it is bound to produce strong noise. The function of the Discharge Muffler from China manufacturer is to reduce the exhaust noise by gradually reducing the exhaust pressure and attenuating the pulsation of the exhaust pressure.
Discharge Mufflers from China manufacturer are made of aluminized steel or stainless steel. Usually the exhaust muffler consists of a resonance chamber, an expansion chamber and a set of porous tubes. Some also fill the Discharge Muffler from China manufacturer with heat-resistant sound-absorbing material, and the sound-absorbing material is mostly glass fiber or asbestos. The exhaust gas flows into the expansion chamber and the resonance chamber through the porous tube. During this process, the exhaust gas continuously changes the flow direction, gradually reduces and attenuates its pressure and pressure pulsation, consumes its energy, and finally reduces the exhaust noise.
