GRWA stainless steel exhaust car muffler
Muffler - The function of a Muffler or a Silencer in Vehicle is to cool the exhaust gases by expansion through it and to reduce the noise of outgoing gases. The exhaust gases must be discharged into the atmosphere with minimum restriction. The restriction in flow of exhaust gases causes back pressure.Back pressure on piston head during exhaust stroke due to restriction of flow of exhaust gases. It is generally 0.7 - 0.9 Kg/cm2 at maximum rpm. The back pressure at low value by proper designing of exhaust system. High back pressure results in higher bhp loss at particular speed, Dilution of fresh charge with exhaust gases, Increased fuel consumption. Back pressure can be reduced by proper design which may become bulky and costly. The exhaust manifold are made of cast iron or steel. Bend should be such made as to give minimum restriction. Muffler design have internal baffles which restrict the flow of gases and cause back pressure. It reduce noise effectively with more rise in back pressure.
The last specified function is the function of the car muffler. It is necessary because the gas coming from the combustion in the pistons of the engine would generate an extremely loud noise if it were sent directly in the ambient surrounding through the exhaust valves.
Stainless steel exhaust muffler pipe for universal car include: resistance muffler, resistive muffler, microperforated panel muffler. The first use of the muffler is to use the abrupt change of the pipeline cross section (ie, the change of the acoustic impedance) so that the acoustic wave propagated along the pipe can be reflected back toward the sound source, so that the sound energy can be reflected back to the original place; the car muffler secondly uses the reflection of several interfaces to make the original A forward propagating sound wave is returned to its origin, and it is folded back and forward again. This point merges with the second forward propagating sound wave that has not yet been reflected, and both are equal in amplitude and 180 degrees out of phase. Odd multiples, which cancel each other out.GRWA exhaust tips expertly crafted from premium grade materials. Designed by professional, this product will provide you with years of no-hassle, maintenance-free service.
