Diesel engine

A diesel engine equipped with a fuel injection device having a fuel supply pump for pressingly sending a fuel, a common rail for accumulating the fuel pressingly sent from the fuel supply pump, injectors for injecting the fuel into cylinder engines by an electronic control, an engine operating condition detection means for detecting engine operating condition and an injection quantity control arithmetic means for calculating a target common rail pressure, a total amount of injection, the number of multistage injections, the respective injection quantity and the respective injection timing based on an output of the engine operating condition detection means, the diesel engine comprising:

• 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 is changed by the total injection quantity increasing means when the engine is transferred from a cold state to a warming state.
