An engine ECU executes a program including detecting, when refueling with an alcohol fuel is performed, a refueling amount of the alcohol fuel based on a signal transmitted from a sender gauge, increasing DI ratio r that is a ratio between a fuel injection amount from an in-cylinder injector and a fuel injection amount from an intake passage injector, according to the refueling amount of the alcohol fuel, such that the ratio of the fuel injection amount from the in-cylinder injector is higher, and retarding the ignition timing according to the refueling amount of the alcohol fuel.
