Abstract
The application is directed to a diesel engine.

A diesel engine comprising:
- a fuel injection pump whose fuel injection amount is adjusted by moving a rack to change a rotation position of a plunger,
- an actuator operating the rack;
- a starter making the plunger perform a stroke operation;
- and
- a control unit controlling the actuator and the starter following an operation of a key switch,
- wherein the control unit makes the rack perform a predetermined operation by the actuator when the key switch is operated from an OFF position to an ON position, and if the rack cannot finish the predetermined operation for a predetermined period of time due to the key switch being held at a START position, the control unit makes the plunger perform the stroke operation by the starter and makes the plunger perform a preliminary stroke operation which stops the stroke operation of the plunger before starting the diesel engine.
