Vehicle intake pipe silencer

Abstract

The invention discloses a vehicle intake pipe silencer. The vehicle intake pipe silencer comprises a shell, and further comprises an intake port, an intake pipe exhaust port, an exhaust pipe, a silencing separation plate and a resonance inner cavity; the intake port is connected with the intake pipe; the intake pipe is connected with the resonance inner cavity; the resonance inner cavity is connected with the exhaust pipe; the exhaust pipe is connected with the exhaust port; the silencing separation plate is embedded in the inner wall of the intake pipe; an air guide port is formed in middle of the cylinder wall of the silencing separation plate for effectively absorbing noise generated in the intake pipe; and a space extends from the resonance inner cavity for absorbing the noise. A silencing cavity is directly machined by using an aluminum pipe, so that the ductility of the aluminum pipe is fully exerted, the production of the silencer is finished under the condition of no breakage, the machining ratio reaches 52%, the whole machining process is environment-friendly without pollution, the traditional die-casting can be replaced, the pollution is reduced, and the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the field of automobile mufflers, in particular to an automobile air intake pipe muffler. Background technique [0002] In recent years, urban motor vehicles have grown rapidly, and the accompanying phenomenon of traffic noise pollution has become increasingly prominent. The biggest hazard of automobiles to environmental protection is noise pollution. The survey shows that motor vehicle noise accounts for 85.5% of urban traffic noise. The development of energy saving and emission reduction requires automobiles to reduce noise and save energy consumption. The main noise of the car comes from the exhaust system of the car, that is, the noise of the exhaust emission of the car. In order to reduce the noise of the exhaust emission of the car and meet the requirements of the car's environmental protection, the traditional car exhaust system realizes noise reduction by installing a muffler. Inside the muffler, a simple tube group wi...

Problems solved by technology

[0003] However, most of the mufflers in the world are used on the air outlet, lacking the setting of the air inlet muffler. At the same time, most of the traditional mufflers use traditional die-casting for material processing, which pollutes a lot, and the equipment is difficult to process, resulting in The scrap rate is high, and the surface of the muffler is not smooth enough by using the traditional alkaline cleaning process. How to reduce the weight of the equipment and use better materials for processing has become a technical problem now.
