Abstract

The invention discloses an engine air intake system. The engine air intake system comprises an air intake header pipe, an electronic actuator, an air intake manifold and a rotary valve, wherein the electronic actuator is arranged on the air intake header pipe and connected with an ECU in a controlled manner; the air intake manifold is provided with multiple manifold channels which are in parallel and different in length, and each manifold channel communicates with the air intake header pipe; and the rotary valve is arranged at the position where the multiple manifold channels inside the air intake manifold communicate with the air intake header pipe and connected with the electronic actuator in a controlled manner. By means of the engine air intake system, the different lengths of the air intake manifold can be switched according to different operation conditions of an engine, and meanwhile, the flow area of the air intake manifold can be adjusted; and the air intake requirements for different working conditions are met better so that performance of the engine can be improved.

Description

technical field [0001] The invention relates to the field of engines, in particular to an engine intake system. Background technique [0002] Existing diesel engine air intake systems usually use ordinary single-channel intake manifolds. Usually, the length of the intake manifold is determined, and the flow cross-sectional area is also determined. The determined structural parameters cannot meet the needs of different intake manifolds under different operating conditions. The requirements of length and flow cross-sectional area will affect the performance of the engine. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. Contents of the invention [0004] The purpose of the present invention is to provide a...
