When an internal combustion engine is stopped, a ratio of a quantity of fuel injection from an in-cylinder fuel injection valve to the total fuel injection quantity is increased and a ratio of a quantity of fuel injected from a manifold fuel injection valve to the total fuel injection quantity is decreased. Thereafter, the internal combustion engine is stopped. In this manner, a quantity of fuel adhered to an intake manifold when the internal combustion engine is stopped is reduced, and deterioration in emission can be suppressed.
