ツキング音低減制御装置。 The diesel engine is equipped with a knock sensor that detects knocking noise, a water temperature sensor that detects the temperature of engine cooling water, an engine rotation speed detector, and a load sensor that detects the engine load. Under conditions where the detector and load sensor detect low water temperature, low rotation, and low load, if the detection value of the knock sensor is determined to be greater than the set knock strength, the injection pump will inject with a delay in injection timing. A diesel knocking noise reduction control device characterized by comprising a control section having a closed circuit configuration for issuing a quantity reduction command.
