A control device for an internal combustion engine includes: an EGR control unit executing open/close control over an EGR valve on the basis of an operating state of the engine; and a fuel injection control unit carrying out at least one of port injection and in-cylinder direct injection by operating at least one of a port injection injector and an in-cylinder direct injection injector on the basis of the engine operating state. The fuel injection control unit sets an EGR non-operation in-cylinder direct injection region, in which the port injection is stopped and the in-cylinder direct injection is carried out while the EGR valve is closed, within an operation range of the engine, and sets part of an EGR operation port injection permissible region, in which at least the port injection is carried out while the EGR valve is open, within the EGR non-operation in-cylinder direct injection region. |
