Abstract

A control device for an internal combustion engine capable of performing additional injection in addition to regular injection includes an electronic control unit. The electronic control unit is configured to calculate an ignition timing at a predetermined crank angle before a compression top dead center. The electronic control unit is configured to calculate an injection amount of fuel at a predetermined time interval and to calculate an injection amount of the fuel at the predetermined crank angle. The electronic control unit is configured to control the fuel injection valve such that the fuel injection valve additionally injects the fuel in an increase amount before ignition, when the injection amount calculated at the predetermined crank angle is increased due to retardation of the ignition tinting calculated after the fuel in the injection amount calculated at the predetermined time interval is regularly injected.
