可変可能にしたことを特徴とする燃料圧力を高低
圧任意に可変可能な電子制御燃料噴射装置。 In an electronically controlled fuel injection system comprising a control unit for controlling fuel injection and a pressure regulator for controlling the fuel pressure of a fuel injection valve whose fuel injection time frequency is controlled by the control unit, the control unit actively controls the fuel pressure. In order to be able to vary the engine negative pressure, a constant pressure valve that controls the negative pressure by inputting engine negative pressure and a pressure sensor that monitors the fuel pressure are provided, and the pressure sensor output is input to the control unit, and in response to the input, the control unit outputs to the constant pressure valve. This system controls the generated negative pressure and inputs the controlled negative pressure into the pressure regulator atmospheric chamber in a closed loop, making it possible to arbitrarily vary the fuel pressure to high or low pressure. Electronically controlled fuel injection device with low pressure that can be adjusted arbitrarily.
