Embodiment Construction

[0028] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0029] Aiming at the problem that the length and air volume of the current automobile intake pipe cannot be adjusted. The invention provides an adjustable engine air intake system, which uses a three-way control chamber to connect the first dirty air intake pipe, the second dirty air intake pipe and the third dirty air intake pipe of different lengths respectively, and through the three-way control chamber Adjust the length of the intake pipe to adjust the intake air volume of the engine. The invention solves the problem that the air intake length and air intake volume of existing automobiles cannot be adjusted, which easily causes excessive noise inside the car, increases the flexibility of air intake volume ad...

Abstract

The invention provides an adjustable engine air inlet system. The adjustable engine air inlet system comprises an air filter, an air inlet clean tube, a first air inlet dirty tube, a second air inlet dirty tube, a third air inlet dirty tube and a three-way control cavity, wherein an air inlet of the air filter is communicated with the air outlet end of the first dirty air inlet tube, an air outlet of the air filter is communicated with the air inlet end of the clean air inlet tube, and the air outlet end of the clean air inlet tube is communicated with an air inlet manifold of the engine. The air inlet end of the first air inlet dirty tube is communicated with the air outlet of the three-way control cavity, the first air inlet of the three-way control cavity is communicated with the second air inlet dirty tube, and the second air inlet of the three-way control cavity is communicated with the third air inlet dirty tube. The length of the second dirty air inlet tube is smaller than that of the third dirty air inlet tube. The three-way control cavity controls the second air inlet dirty tube or the third air inlet dirty tube to be communicated with the first air inlet dirty tube according to a working condition instruction of an engine controller. The flexibility of air inflow adjustment can be improved, and the using comfort of an automobile is improved.

Description

technical field [0001] The invention relates to the technical field of engine intake pipes, in particular to an adjustable engine intake system. Background technique [0002] The engine intake pipes used in current automobiles often cause intake resonance due to the mismatch between the intake air volume and the working conditions, making the intake sound louder, seriously affecting the noise in the car and affecting the ride comfort. At the same time, the existing intake pipe has a fixed length, and the length of the intake pipe cannot be changed according to the vehicle speed, and the intake air volume cannot be adjusted according to the increase or decrease of the vehicle speed, resulting in excessive intake noise. Contents of the invention [0003] The invention provides an adjustable engine air intake system, which solves the problem that the length and air intake volume of existing automobiles cannot be adjusted, which easily causes excessive noise in the car, increa...
