Embodiment approach

[0049] According to a further preferred embodiment of the air intake method provided by the present invention, the method further includes a control step and an engine throttle detection step.

[0050] Such as Figure 6 As shown, the engine throttle detection step is used to detect the position of the engine throttle, convert the detected position of the engine throttle into an electrical signal representing the position of the engine throttle, and send the electrical signal to the control step.

[0051] The control step is used to convert the electric signal into an opening value ΔS representing the opening degree of the throttle valve, and control the opening value D of the valve 5 according to the opening value ΔS.

[0052] The larger the opening of the throttle valve, the more gas is needed, and the opening of the valve 5 is correspondingly increased to allow sufficient air to enter the engine. The opening value ΔS and the opening value D are in direct proportion. In orde...

Abstract

An engine air intake system is provided, which comprises an intake manifold. The intake manifold comprises a gas inlet and at least one gas outlet. Wherein, the air intake system comprises at least one buffer pool; the buffer pool communicates with the intake manifold; the distance between the interface at the joint of the buffer pool and the intake manifold is less than the distance from the interface at the joint of the buffer pool and the intake manifold to the air inlet. In addition, this invention provides an air intake method for engine. Therefore, the air intake system and method in this invention are able to realize high air intake efficiency.

Description

technical field [0001] The present invention relates to an engine air intake system and method. Background technique [0002] The air movement in the intake passage of the engine has a decisive influence on the formation of the mixture and the combustion process. Therefore, it also affects the power, economy, combustion noise and harmful exhaust emissions of the engine. Well-organized air movement can improve the flame of the gasoline engine. Propagation rate, reduction of combustion rate, reduction of combustion cycle variation, tissue lean combustion or layer combustion play an important role. [0003] The engine air supply method mainly utilizes the aerodynamic effect in the intake pipe to realize the air intake of the engine. The aerodynamic effect can be regarded as the joint result of the airflow inertia effect and the airflow pressure fluctuation effect. [0004] In the airflow inertia effect, the inertial effect of the high-speed flowing gas in the intake pipe is g...
