ABSTRACT:
An internal combustion engine includes a port injector injecting a fuel into an intake port, an in-cylinder injector directly injecting a fuel into a combustion chamber, and an ECU. When the ECU determines that an operation state of the internal combustion engine exhibits a transition state, the ECU obtains an estimated load factor of the internal combustion engine based on the operation state of the internal combustion engine, and calculates a fuel injection ratio between the port injector and the in-cylinder injector based on the estimated load factor.
