More Information
Summary:An internal combustion engine includes fuel injection valves and an ECU. In the internal combustion unit, predetermined injection is performed when the bed temperature of a catalyst is lower that a predetermined temperature. In the predetermined injection, fuel is injected from a first fuel injection valve, from among the fuel injection valves, within the valve opening period of an intake valve, and fuel is injected from a second fuel injection valve, from among the fuel injection valves, within the valve opening period of an exhaust valve. In the internal combustion engine, a first injection amount is specifically injected from the first fuel injection valve in the predetermined injection.
