Problems solved by technology

At present, for motor vehicles, most of them only pay attention to the exhaust noise control of the engine, and pay little attention to the intake noise.
At present, the air filter installed in the air intake system (structure such as figure 1 shown), it can only serve the purpose of filtering air and preventing dust

Embodiment Construction

[0016] The present invention will be further described in conjunction with the following drawings, but does not limit the present invention.

[0017] Such as figure 2 Shown: the present invention is applicable to the muffler filter of supercharged internal combustion engine air intake system, and it comprises by upper and lower dividing plate 4,7 and it is divided into cavity A, B, C and its cross-section is the closed shell of circle The body 1 is provided with imitation Y-shaped pipes in chambers A and B. The imitated Y-shaped pipes are composed of two intake branch pipes 3 and the middle muffler pipe 5. Both intake branch pipes 3 pass through gradually larger tapered transition pipes. Converge at the middle muffler pipe 5, and the air intake branch pipe 3 and the middle muffler pipe 5 are at 90°; the two air intake branch pipes 3 are located in cavity A and extend to the outside of the closed shell 1, and the middle muffler pipe 5 extends downward To the chamber B and the...

Abstract

The silencing filter suitable for supercharging internal combustion engine air inlet system includes one closed casing, one upper and one lower partition boards to separate the casing into three cavities, A, B and C, one Y-shaped pipe inside cavities A and B with through holes and comprising two air inlet branches inside cavity A and one intermediate silencing pipe downwards extending to cavity B, sound absorbing material filled inside cavity A, one cylindrical microporous plate around the silencing pipe inside cavity B, one cylindrical filter inside cavity C, one exhaust silencing pipe in the center of the cylindrical filter with closed upper end fixed on the lower partition board, lower end extending beyond the closed casing and connected to the air inlet pipe of the internal combustion engine and through holes on the pipe wall, one air passage between cavity B and cavity C, and one drainage pipe in the bottom of cavity C. The silencing filter has integrated air filtering, self cleaning and noise eliminating functions.

Description

technical field [0001] The invention relates to a filter device for an air intake system of an internal combustion engine, in particular to a muffler filter suitable for the air intake system of a supercharged internal combustion engine. Background technique [0002] At present, the air intake system of internal combustion engines in my country is equipped with an air filter, which mainly acts as a filter for air. But there is no new type of noise reduction filter integrating noise reduction, filtration and self-cleaning capabilities. Because the internal combustion engine is equipped with an exhaust gas turbocharger, its rotating speed is very high, some up to more than 16000r / min. The rotating noise generated by the compressor blades of the turbocharger periodically hitting the air and the vortex sound formed by the high-speed airflow are continuous high-intensity high-frequency noises. Its main energy distribution is between 500Hz and 10000Hz. Its peak and harmonics ar...
