置。 In a device that controls engine rotation speed by adjusting the fuel injection amount of a fuel injection device, there is an actuator that adjusts the fuel injection amount, a position detector that detects the operating position of this actuator, and a rotation that detects the engine rotation speed. The engine comprises a number detector and a setter for setting a target rotational speed of the engine, and the output signal of the position detector is passed through a high-pass filter and a phase lead circuit to form a comparison signal with the setting signal of the setter. A fuel injection control device for an engine, characterized in that a comparison signal and an output signal of the rotation speed detector are input to a proportional/integral/differential calculation circuit to drive the actuator and adjust the fuel injection amount.
