Abstract:
A control device for an internal combustion engine provided with a combustion control part successively performing at least first main fuel injection and second main fuel injection and making the fuel burn by premix charged compressive ignition so as to cause generation of heat two times in stages inside the combustion chamber and cause the pressure waveform showing the change along with time of a rate of cylinder pressure rise to become a two-peak shape. The combustion control part calculates a second premix time of fuel injected by the second main fuel injection with air, reduces the injection amount of the second main fuel injection so that the second premix time becomes a first threshold value or more and performs after fuel injection after the second main fuel injection when the second premix time is less than the first threshold value, and injects the amount of fuel reduced from the injection amount of the second main fuel injection by the after fuel injection.
