    摘要: The purpose of the present invention is to provide a diesel engine that can be smoothly started even in a situation where a plunger has become difficult to rotate due to sticking of the plunger that is caused by a fuel film formed on the outer periphery of the plunger. When a key switch 80 is operated from an off-position to an on-position, a control unit 70 of this diesel engine 1 controls an actuator 48 so as to cause a rack 45 to perform a predetermined operation X. If the rack 45 cannot complete the predetermined operation X within a predetermined amount of time Ta, on condition that the key switch 80 is held at a start-position, the control unit controls a starter 60 so as to cause a plunger 34 to perform a preparatory stroke operation whereby the plunger 34 is caused to perform a stroke operation, and the stroke operation by the plunger 34 is stopped before the diesel engine 1 starts.

    摘要: A fuel injection device of a diesel engine capable of smoothly starting the diesel engine to match an environment around the engine by saving a fuel, reducing the exhaustion of carbon dioxide, and suppressing black smoke in starting the diesel engine. A rack (45) is operated by an actuator (41) from a lowest rack position to a starting increased fuel amount position at a lower speed than that at which the rack is operated by the actuator from the lowest rack position to the starting increased fuel amount position at the maximum operating speed. The operating speed of the rack (45) is set in two stages, and the later operating speed of the rack is reduced less than the operating speed of the rack up to a set intermediate rack target value P2. Then, the operating amount of the rack (45) per hour is reduced after the ignition of the engine (1) is recognized. Also, the operating speed of the rack (45) is controlled according to an atmospheric temperature in starting the engine.
