When divisional pilot injection is executed twice with first pilot injection and second pilot injection, a second pilot injection pressure setting value is set in accordance with the function required for the pilot injection, which is a preheating function or a premix function. After the execution of the first pilot injection, fuel pressure that ascents or descents by pulsation generated in the inside of an injector is detected by a sensor, and the second pilot injection is executed at a timing when the fuel pressure matches the second pilot injection pressure setting value. |
