The exhaust pipe of a car is the main reason for driving noise. Countries around the world have strict regulations on the noise limits of various vehicles. The exhaust muffler is such a device for reducing exhaust noise.  1.Exhaust Muffler The function of the exhaust muffler is to eliminate noise by reducing and attenuating the pulsation of the exhaust pressure. According to the principle of interference, the exhaust muffler has two basic modes of absorption and reflection. The shock absorbers reduces its energy by friction of the exhaust gas on sound absorbing materials such as the glass fiber, the steel fiber and...

Automotive exhaust systems are designed to move hot gases from the engine to the rear of the car and into the air stream. How to modify exhaust system? Car enthusiasts will often modify a car’s exhaust system in order to increase the engine performance or get the noise of the engine to achieve a specific pitch. Exhaust System Components include: Exhaust manifoldHead pipeFlange gasketCatalytic converterOxygen sensorsPrimary transfer pipePressure diverterSecondary exhaust pipeMufflerResonatorTail pipeHeat shieldsSystem hangers (rubber) It requires good knowledge of your car’s exhaust system, but it can be completed with a minimum of fuss, provided you follow some basic guidelines.

The exhaust system is a contradictory intersection of the car. On the one hand, it is responsible for the environmental protection of emissions, and on the other hand, it has a great effect on the power and weight of the vehicle.  Function of Exhaust System The function of the exhaust system is to collect exhaust gas from each engine cylinder, reduce exhaust noise and eliminate flames and sparks in the exhaust gas, so that the exhaust gas is safely discharged into the atmosphere, and control the emission of harmful substances in the exhaust gas. Composition of Exhaust System Exhaust system is generally composed...
