CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

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 for causing premix charged compression ignition of fuel so that a pressure waveform showing a change of a rate of cylinder pressure rise over time becomes a two-peak shape and a peak ratio which is a ratio of a first peak value of a first peak of the pressure waveform and a second peak value of a second peak falls within a predetermined range. The combustion control part calculates the ignition delay time of the fuel injected by the second main fuel injection (second ignition delay time) and reflects the injection correction amount in the target injection amount of the second main fuel injection (second target injection amount) if an injection correction amount is set for the amount of fuel injected from the fuel injector and the second ignition delay time is less than a predetermined value.
