PROBLEM TO BE SOLVED: To prevent malfunction at the time of executing a purge processing for fuel evaporative emission, in an internal combustion engine provided with a cylinder injection injector and an intake passage injection injector. SOLUTION: When a requirement to change over to cylinder injection or port injection is detected (YES in S100) and a purge control flag is in an ON state (YES in S120), an engine ECU executes a program including a step (S130) of reducing a purge flow rate, a step (S150) of executing a processing for changing over to the cylinder injection or port injection, and a step (S170) of gradually increasing the reduced purge flow rate to a target purge flow rate after lapse of time previously set from injection changeover (YES in S160).
