ABSTRACT:
An internal combustion engine including an in-cylinder injection injector and an intake port-injection injector. An ECU includes a fuel injection duration calculation portion that calculates a requested fuel injection duration and a fuel injection control portion that causes the in-cylinder injection injector to inject fuel during the compression stroke during the cold start of the engine, and that causes fuel to be injected also in a manner other than the fuel injection performed by the in-cylinder injection injector during the compression stroke if the requested fuel injection duration is longer than or equal to an interval time. Therefore, even if the requested fuel injection duration is longer than or equal to the interval time, the emissions can be reduced while a startability during a cold start of the internal combustion engine is secured.
