ABSTRACT:
In a diesel engine10equipped with a fuel injection device50having a fuel supply pump53for pressingly sending a fuel, a common rail52for accumulating the fuel pressingly sent from the fuel supply pump, injectors51for injecting the fuel into a cylinder by an electronic control, a coolant water temperature sensor64for detecting an engine coolant water temperature and a fuel injection quantity map for calculating a target common rail pressure, total amount of injections, the number of multistage injection, the respective injection quantity and the respective injection quantity timing, the diesel engine10comprises a total injection quantity increasing means for increasing the total amount of injections in the injection quantity control arithmetic means and an injection number reduction avoidance means for avoiding that the number of multistage injections are changed by the total injection quantity increasing means when the engine is transferred to a cold state to a warming state.
