ジンの噴射時期制御装置。 Equipped with a load sensing timer having a governor sleeve that is movably supported in the axial direction on the governor shaft and whose movement is controlled according to the engine load,
An injection timing control device for a diesel engine that controls fuel injection timing by controlling the escape of internal pressure of a fuel injection pump through an orifice provided in a governor sleeve and a fuel pressure relief passage formed in a governor shaft. The governor shaft is configured to be movable in the axial direction, and a moving means is provided for moving the governor shaft to cut off communication between the orifice and the fuel pressure relief passage when the engine is under low load or no load. Features: Diesel engine injection timing control device.
