Abstract
The utility model relates to a silencer of an automobile. Noise of the automobile mainly includes noise of an engine of the automobile, pneumatic noise generated in the process that the automobile travels, and noise generated between tires and the road surface in the process that the automobile travels, wherein the intensity of the noise of the engine gets higher along with increase of the rotating speed of the engine, the noise is wide in influence and long in duration, and is the largest part of the noise of the automobile, and the comfort level of the automobile is influenced. An existing silencer of an automobile is poor in silencing effect, and the quantity of generated noise is still large. The silencer of the automobile comprises a gas inlet pipe (1), wherein the gas inlet pipe (1) is installed at the front end of a noise absorption chamber, a gas inlet pipe A (7) is installed in the noise absorption chamber, a gas outlet pipe A (4) is installed in the noise absorption chamber, and a gas outlet pipe (5) is installed at the tail end of the noise absorption chamber. The silencer of the automobile is used for lowering noise of automobile exhaust.
