PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine improving drivability by agreeing an output torque of an internal combustion engine to a demand torque in changeover of a combustion mode. SOLUTION: This control device 1 changes over the combustion mode between a stratified combustion mode and a homogenous combustion mode and controls the fuel injection amount based on the demand fuel amount TCYLBS. ECU 2 of the control device 1 estimates combustion efficiencies KLMTCYH, KLMTCYSD and KLMTCYL of the internal combustion engine 3 and calculates a changeover demand combustion amount TCYLLT as the demand fuel amount TCYLBS according to a demand fuel amount TCYLLTIN and a demand torque PMTCYLIN calculated according to the operation state of the internal engine 3 right before the changeover, a demand torque PMCMDREG of this time and the fuel efficiency of this time.
