The muffler of the exhaust pipe broke down and began to shake.

If the muffler is broken, it will be big, because this may be a little broken, and this can't be seen under the car. I suggest you go to the repair shop to have a check. Car muffler is mainly used to reduce the noise generated by motor vehicle engines. Its principle is that the automobile exhaust pipe consists of two pipes with different lengths, which are separated first and then merged. Because the length difference between the two pipes is equal to half the wavelength of the sound wave emitted by the car, when they are superimposed, the sound waves of the two lines will interfere with each other, thus weakening the sound intensity and reducing the transmitted sound, thus achieving the effect of silencing. The muffler is broken: 1. If you listen to the noise outside the car with the air conditioner on, it is basically normal if it is loud. Because the compressor works and the fan works, there will be sound. Car muffler is a special equipment to prevent and control the dynamic noise of airflow, which hinders the sound propagation and allows airflow to pass through. 2. At present, in order to suppress the environmental noise caused by high-pressure airflow, there are many types of silencers in the world, most of which adopt the principle of impedance compound silencing; 3. Due to complicated structure, heavy weight, high-temperature oxidation sound-absorbing filler, high-speed airflow impact sound-absorbing filler, water vapor infiltration sound-absorbing filler and other reasons, frequent maintenance of muffler, poor noise elimination effect and short service life have always been the key problems faced by car muffler. Through Bian Xiao's introduction, I want to know whether you start to tremble when the exhaust muffler breaks. Is everything all right? I hope the above introduction can help you.
