An internal combustion engine includes an in-cylinder injector for injecting fuel into a combustion chamber of the engine and an intake system injector for injecting fuel into an intake system connected to the combustion chamber. In a starting state of the engine, an electronic control unit (ECU) causes the in-cylinder injector to perform only the initial injection to the combustion chamber, and causes the intake system injector to perform fuel injections after the initial injection. As a result, favorable engine startability is ensured, and the emission of unburned components is suppressed in the engine starting state.
