Abstract

The invention discloses an engine gas inlet system of an automobile. The engine gas inlet system of the automobile comprises an upper shell, a lower shell, a filtering element and a first air inlet pipe for conveying gas to the filtering element, and further comprises a vacuum box cover plate, a first connecting pipe, a second connecting pipe, a third connecting pipe, a vacuum motor, a vacuum electromagnetic valve, an air inlet baffle and a second air inlet pipe used for conveying gas to the filtering element. The upper shell and the vacuum box cover plate form a vacuum box, and the vacuum box is connected with an engine air inlet manifold and the vacuum electromagnetic valve through the first connecting pipe and the second connecting pipe. The air inlet baffle is located in the second air inlet pipe. The vacuum motor comprises a motor cover plate, an electric membrane and a pull rod, the motor cover plate and the elastic membrane form vacuum space, and the vacuum space is communicated with the vacuum electromagnetic valve through the third connecting pipe. One end of the pull rod is fixedly connected to the outer side of the elastic membrane, and the other end of the pull rod is hinged to the air inlet baffle. According to the engine gas inlet system of the automobile, the inflating efficiency and the NVH performance of an engine can be easily improved. The invention further discloses the automobile comprising the engine air inlet system.

Description

technical field [0001] The invention relates to the technical field of automobile air intake devices, in particular to an automobile engine air intake system.
