Abstract
An exhaust silencer for vehicle comprises a first level silencer and a main silencer. Three inner cavities are positioned in the first level silencer successively, an air inlet pipe and an exhaust pipe are positioned respectively in the inner cavities at two ends, and the air inlet pipe and the exhaust pipe are equipped with a noise elimination hole. The main silencer is equipped with four inner cavities successively, an air inlet pipe parallel to the main silencer is equipped with three bypass pipes, and three bypass pipes are communicated with four inner cavities. The air inlet pipe of the main silencer is communicated with the exhaust pipe of the first level silencer. By adding the first silencer at the front end of the main silencer, the utility model reduces the exhaust back pressure, decreases the loss on the engine power, and meanwhile effectively reduces the noise.
Description
Technical field:
The utility model relates to vehicle, relates in particular to petrolic outlet pipe, particularly a kind of automobile exhaust muffler.
