ABSTRACT:
A control system includes: a detecting device that detects the transition in the cumulative amount of heat generated in a combustion chamber based on the pressure in the combustion chamber in an expansion stroke; and a controller that controls the amount of exhaust gas contained in an air-fuel mixture in the combustion chamber such that the amount of change in the cumulative amount of heat generated in the combustion chamber through a predetermined crank angle range will become a predetermined value.
