Abstract
The utility model provides a composite silencer for end gas or pipeline air current of internal combustion engines, and the composite silencer is provided with a device which reduces noise or purifies. Bar bodies which have material characteristic are arranged on lateral plates which are oppositely separated, and the lateral plates are enclosed by coaming plates to form more than one chamber. After air enters into the opening positions of the lateral plates, the air continuously changes the direction of the air at the surfaces of the bar bodies, the air absorbs and generates reflection to reduce noise, and the air is discharged. The composite silencer can be made into the shape which is matched with the cylinder body of the existing vehicle and the motor cycle silencer to arrange in the cylinder body of the existing vehicle and the motor cycle silencer or in the air flow pipeline, and the noise is obviously lower than the noise of the existing silencer. The composite silencer has simple structure, easy manufacture and strong applicability.
