PROBLEM TO BE SOLVED: To accurately grasp a combustion state based on an ignition delay period and a period from ignition start until combustion peak or a combustion period, and optimally control the combustion state based on this. SOLUTION: This control device for an internal combustion engine is provided with a sensor 36 detecting cylinder inner pressure and a sensor 33 detecting a crank angle. An engine controller 31 calculates the ignition delay period of fuel and the combustion period from the ignition start until the combustion peak is reached or until the combustion is completed, based on the cylinder inner pressure and the crank angle. Based on the ignition delay period and the period until the combustion peak or the combustion period, fuel injection timing, exhaust recirculation amount or the like which are elements affecting combustion are correctively controlled.
