Stainless Steel Exhaust Muffler For Honda Civic

Car Muffle is a product that suppresses exhaust noise

The function of the exhaust muffler is to reduce the exhaust noise by gradually reducing the exhaust pressure and attenuating the exhaust pressure fluctuation.

The Exhaust Pipe Muffler of the engine is about 0.3~0.5MPa, and the temperature is about 500~700℃, which indicates that the exhaust has a certain energy. At the same time, due to the intermittent exhaust gas, the exhaust pressure pulsation is caused in the exhaust pipe. If the engine exhaust is discharged directly into the atmosphere, it is bound to produce strong noise.

The silencer is made of aluminized steel or stainless steel. Usually the muffler consists of a resonance chamber, an expansion chamber and a set of porous tubes. Some are also filled with heat-resistant sound absorbing materials in the muffler, and the sound absorbing materials are mostly glass fiber or asbestos. The exhaust gas flows into the expansion chamber and the resonance chamber through the porous pipe. In this process, the exhaust gas constantly changes the flow direction, gradually reduces and attenuates its pressure and pressure pulsation, consumes its energy, and finally reduces the exhaust noise.
