Abstract
A control device for an internal combustion engine in which a direct injector that directly injects fuel into a corresponding one of a plurality of cylinders and a port injector that injects fuel into an intake port are both provided on each of the plurality of cylinders includes: a control unit that controls a fuel injection amount from the direct injectors and the port injectors; and an imbalance detecting unit that, in a state where fuel is injected from both of the direct injectors and the port injectors, detects an imbalance in air-fuel ratio among the plurality of cylinders. When the imbalance in air-fuel ratio is detected by the imbalance detecting unit, the control unit controls the fuel injection amount from the direct injectors and the port injectors such that fuel is injected from one of the direct injectors and the port injectors.
