Abstract

The invention discloses a silencer which comprises a hollow barrel body, an air inlet pipe, an air outlet pipe, a connecting pipe and a silencing device, wherein a connecting plate is arranged on thebarrel body to divide the barrel body into a front barrel body and a back barrel body; the air inlet pipe is arranged at the front end of the front barrel body; the front end of the air inlet pipe isconnected to an exhaust manifold of an internal combustion engine and the tail end of the air inlet pipe stretches into the front barrel body; the air outlet pipe is arranged at the tailed end of theback barrel body; the front end of the air outlet pipe stretches into the back barrel body and the tail end of the air outlet pipe is connected to a tail pipe; the connecting pipe is arranged on the connecting plate, is located in the front barrel body and is arranged coaxial with the air inlet pipe; the connecting pipe is located on the right side of the air inlet pipe; and the front end of the connecting pipe is a certain distance from the tail end of the air inlet pipe while the tail end of the connecting pipe communicates to the back barrel body. By adopting the structure, the silencer disclosed by the invention is better in silencing effect.

Description

technical field [0001] The present invention relates to a muffler. Background technique [0002] A muffler is a device that prevents sound from propagating and allows airflow to pass, and is an important measure to eliminate aerodynamic noise. The muffler is a noise reduction device installed on the airflow passage of aerodynamic equipment (such as blowers, air compressors, boiler exhaust ports, generators, water pumps and other equipment with loud exhaust ports) or in the intake and exhaust systems. device. [0003] The muffler is the main component of the driving noise. All countries in the world have strict regulations on the noise limit of various vehicles. The muffler is such a device that is designed to reduce exhaust noise. [0004] The function of the car muffler is to reduce the exhaust noise of the engine, and make the high temperature exhaust gas can be safely and effectively discharged. The performance of the exhaust system has an important impact on the comf...
