制御装置。The system includes a pressure-responsive actuator connected to an idle stopper that regulates the idle position of the control lever of the fuel injection pump, and a control valve that controls the signal pressure to this actuator, and is capable of adjusting the target idle rotation speed and the actual idle rotation speed. In comparison, in a diesel engine idle speed control device that controls the idle speed by controlling the transmission of the drive pulse to the control valve, the pulse width of the drive pulse to the control valve is controlled based on the battery voltage. An idle rotation speed control device characterized in that it is provided with means for controlling.
