Problems solved by technology

[0002] In a vehicle equipped with a turbocharger device, the turbocharger device will produce a huge noise during operation. When the throttle valve is closed, the high-pressure gas in the intercooler pipeline needs to be released quickly through the vent pipe. When releasing, the high-speed airflow will rub against the pipe wall and produce a leak sound, which seriously affects the NVH performance of the vehicle.
[0003] In order to reduce the exhaust sound produced by the gas when the turbocharger is working, the vehicle is equipped with a noise reduction structure. In the related art, the distance between the exhaust pipe connection structure, the muffler structure and the crankcase ventilation pipe structure of the vehicle is relatively long. , and all need to be arranged separately, resulting in complex assembly process and increased manual assembly cost, and the connection structure of all parts needs to be designed separately, which increases manufacturing cost and is not conducive to the integration and light weight of the whole vehicle

Abstract

The invention discloses an air intake muffler and a vehicle provided with the air intake muffler. The air intake muffler comprises an outer housing, an inner housing, a crankshaft ventilation port, anair leakage pipe port, an air filter port and a supercharger port; the inner housing is arranged in the outer housing; a muffling cavity is restricted to form between the outer housing and the innerhousing; a plurality of inner housing through holes are formed in the inner housing and are used for communicating the interior of the inner housing with the muffling cavity; the crankshaft ventilation port is formed in the outer housing and communicates with the muffling cavity; the air leakage pipe port is formed in the outer housing and communicates with the muffling cavity; the air filter portis formed in the outer housing and communicates with the interior of the inner housing; and the supercharger port is formed in the outer housing and communicates with the interior of the outer housing. The air intake muffler can reduce air leakage sound generated by air in the working process of a turbine supercharging device of the vehicle, and allows the structure of the vehicle to be more integrated.
