Car Muffler

What is a car muffler?

Cars contain many components that help reduce the discomfort of riding. The muffler is one of the basic functions to ensure a smooth ride. The muffler is placed at the rear of the vehicle and forms part of the vehicle's engine exhaust system. The mufflers are made of steel and then coated with aluminum to protect them from the heat and chemicals of the exhaust system. A car muffler is used to reduce the motor vehicle engine working noise parts, because the length difference between the two pipes is equal to half of the wavelength of the sound wave issued by the car, so that the two sound waves in the superposition of interference offset each other and weaken the sound intensity so that the sound is reduced, so as to play the effect of muffling.

Principle of the car muffler

The principle of the muffler is that its exhaust pipe is composed of two pipes of different lengths, which are separated and then meet. Because the length difference between the two pipes is equal to half of the wavelength of the sound wave emitted by the car, the two waves cancel each other when they interfere in the superposition and weaken the sound intensity, so that the sound is reduced, so as to play the effect of noise cancellation.

The function of the car muffler 

Every time the exhaust valve is opened, the combustion gas used in the combustion of the engine is released into the exhaust system in large quantities. Therefore, the muffler helps to minimize the noise emitted by the engine and control the engine backpressure. The muffler greatly improves engine performance and durability. Car muffler reduces engine exhaust noise and enables high-temperature exhaust gas to be discharged safely and efficiently. As a part of the exhaust pipe, the muffler should ensure its exhaust is smooth, has small resistance and has sufficient strength. Muffler to 500℃~700℃ high-temperature exhaust, to ensure that in the specified mileage of the car, no damage, no loss of muffler effect.
