Abstract
An internal combustion engine includes an in-cylinder injector injecting a fuel into a cylinder and an intake port injector injecting a fuel into an intake port. In the internal combustion engine, when a fuel injection ratio between the in-cylinder injector and the intake port injector is changed such that the ratio of fuel injection from the in-cylinder injector is increased, ignition timing is retard-corrected for a prescribed period after that change.
