Abstract:
An ECU executes a program including injecting fuel only by an intake passage injector when an engine is idling, starting an addition-type PFI timer, resetting the PFI timer when a count of the PFI timer reaches a set value that is set shorter as the fuel is lighter in fuel property, and injecting the fuel only by an in-cylinder injector.
