Abstract

The invention discloses an engine air intake system, which comprises an air storage tank, an air intake structure, an air outlet structure and an air guide. and a plurality of first air outlets; the air intake structure includes an air intake pipe and a first regulating valve located on the air intake pipe, the inlet end of the air intake pipe is used to communicate with the air source, and the outlet end of the air intake pipe is used for It communicates with the first air inlet; the air outlet structure includes a plurality of air supply branch pipes that communicate with the plurality of first air outlets one by one, and the plurality of air supply branch pipes are used to communicate with a plurality of cylinders; the air guide is arranged on the air intake The pipe is located at the air outlet end of the first regulating valve, and is used to guide the airflow output from the first regulating valve into the air storage cavity. The invention makes the air flow entering the air storage cavity more stable, thereby making the air flow entering each air supply branch pipe more uniform, and the stability of the complete engine is better.

Description

technical field [0001] The invention relates to the technical field of engine components, in particular to an engine intake system. Background technique [0002] The air intake of the engine is the key to the power of the vehicle, and the popularity of supercharged engines has put forward higher requirements for the intake air. In the supercharging stage, the intake pressure of the engine is high, and the requirement for the intake tumble ratio is higher; in the natural intake stage, the intake air volume is mainly determined by the flow coefficient. The higher the flow coefficient, the more gas enters the cylinder per unit time. , the better the engine performance. [0003] The function of the plenum chamber is to evenly distribute the air to the intake ports of each cylinder, so the intake length / flow rate from the throttle valve inlet to each cylinder should be as equal as possible. The uniformity of intake air affects the power stability of the engine. When the uniform...
