The car muffler is mainly used to reduce the noise generated when the engine of the motor vehicle is working, and is one of the key components of the car. Its performance is directly related to the noise level of the car and the driver's hearing experience. So what is the role of car muffler?

Automobile exhaust exhaust muffler is an important part of automobile exhaust system. This article will introduce the internal structure of automobile exhaust exhaust muffler.

We all know that the noise of traditional agricultural tractors is relatively large. The noise mainly comes from diesel engines and exhaust pipes, but the noise of small cars is very small. Why? On the one hand, a lot of sound-absorbing materials are installed in the engine compartment of the car; on the other hand, the exhaust muffler is installed in the car.

The principle of a car silencer is that its exhaust pipe is composed of two pipes of different lengths, which are separated before they meet. Because the difference between the lengths of the two pipes is equal to half of the wavelength of the sound waves emitted by the car, the two columns of sound waves cancel each other and interfere with each other to reduce the sound intensity when superimposed during superposition, so that the sound is reduced, so as to achieve the effect of sound attenuation.

What is exhaust mufflerExhaust Muffler refers to the airflow pipe with noise propagation at the same time, which can be attenuated or reflected back by using the pipe with sound-absorbing lining and the elbow or the pipe with sudden change of cross section area and other discontinuous acoustic imped

History of exhaust muffler With the development of exhaust muffler market in China, the application and research and development of core production technology will become the focus of the industry. This article contains the following:Development historyDesign Construction Development history Early

Development of exhaust muffler In 2012, the production capacity of the mainstream enterprises in the domestic exhaust silencing system industry was further improved, and the scale of the enterprises was gradually expanded. The product structure began to enter the adjustment, the product level increa
