Information

The impact of a broken car muffler on the car includes: increasing the sound of the engine. The car muffler is a part used to reduce the noise generated by the engine of the motor vehicle. The working principle is: the length difference between the two pipes is equal to the sound emitted by the car. Half of the wavelength of the sound wave makes the interference of the two columns of sound waves cancel each other when they are superimposed, which reduces the sound intensity, reduces the sound, and has the effect of silencing.

Automobile mufflers can be divided into: 1. Resistive mufflers: through pipes and partitions inside
When the components form various silencing units such as expansion chambers and resonance chambers, the sound waves reflect and interfere during propagation, reducing the sound energy to achieve the purpose of silencing; 2. Resistive muffler: fill the sound-absorbing material around the pipe through which the internal exhaust gas passes. 3. Impedance composite muffler: a muffler composed of a combination of a resistive muffler unit and a sound-absorbing material, and has the characteristics of a resistive and resistive muffler.
