Abstract

The invention relates to and provides an air intake system of an automobile engine. The air intake system comprises an air-filtering air intake pipe assembly, an air filter assembly and an air-filtering air outtake pipe assembly, wherein the air intake end of the air filter assembly is connected with the air-filtering air intake pipe assembly; the air outtake end of the air filter assembly is connected with the air-filtering air outtake pipe assembly; the air-filtering air intake pipe assembly comprises an air-filtering air intake pipe, a separator, an air intake insertion pipe and a purge valve; the air-filtering air intake pipe is connected with the air filter assembly; the air intake insertion pipe and the separator are both arranged in the air-filtering air intake pipe; the separator is arranged between the air intake insertion pipe and the air filter assembly; the purge valve is connected with the air-filtering air intake pipe; the purge valve is located between the separator and the air filter assembly. The air intake system has the beneficial effects that as multi-stage filtering is formed, the filtering capability is improved, a vortex phenomenon is weakened, and the noise is lowered.

Description

technical field

[0001] The invention relates to an intake system, in particular to an automobile engine intake system. Background technique

[0002] Existing automotive engine air intake systems mainly have the following defects:

[0003] 1. The filtration capacity of the air intake system is mainly realized by the air filter element. The intake system is a single-stage filtration system with limited filtration capacity;

[0004] 2. The gas flow rate in the air filter assembly is uneven, and there is a vortex phenomenon, which increases the intake resistance of the engine and affects the performance of the engine power;

[0005] 3. The noise of the air intake system affects the NVH performance of the vehicle, and if the noise control is not in place, it will affect the noise quality of the vehicle and cause customer dissatisfaction. Contents of the invention

[0006] In order to solve the problems in the prior art, the invention provides an automobile engine air intake s...
