An internal combustion engine (1) includes a port injector (10p) injecting a fuel into an intake port (4), an in-cylinder injector (10c) directly injecting a fuel into a combustion chamber (2), and an ECU (20). When the ECU (20) determines that an operation state of the internal combustion engine (1) exhibits a transition state, the ECU (20) obtains an estimated load factor of the internal combustion engine (1) based on the operation state of the internal combustion engine (1), and calculates a fuel injection ratio between the port injector (10p) and the in-cylinder injector (10c) based on the estimated load factor. |
