The air flow sensor (hereinafter referred to as air flow sensor) is widely used in L-type electronically controlled gasoline engines. Its function is to directly detect the amount of air entering the engine cylinder, convert the air flow into an electrical signal, and transmit it to the electronic control unit (ECU). The electronic control unit calculates the basic injection amount based on the air flow sensor signal and the engine speed signal; plus the additional value calculated by other information input to the control unit, it sends a control signal to the injector, controls the injection time of the injector, and regulates the concentration of the combustible mixture to meet the needs of various engine working conditions.
