Abstract
An internal combustion engine includes a port injection valve, a direct injection valve, and a forced-induction device. A ratio of an amount of fuel injected from the port injection valve with respect to a total amount of fuel supplied for one fuel combustion in the cylinder is defined as a port injection ratio. The internal combustion engine is controlled such that, in a case in which a condition is satisfied that the forced-induction device is in an operation of performing forced induction and the internal combustion engine is in an engine operation region in which a valve overlap period is greater than zero, the port injection ratio is set to be small and a start timing of fuel injection from the port injection valve is delayed as compared with a case in which the condition is not satisfied.
