ABSTRACT:
An internal combustion engine includes an in-cylinder injection valve and an intake passage injection valve. A control apparatus of the engine determines whether a catalyst located in an exhaust passage is in an overtemperature condition. When the catalyst is determined to be in the overtemperature condition, the control apparatus controls the injection valves to increase the amount fuel supplied to the cylinder compared to a case where the catalyst is determined not to be in the overtemperature condition. The control apparatus sets a mode for causing the injection valves to increase the amount of supplied fuel according to an operational state of the engine. For example, in a case where the component is determined to be in the overtemperature condition when the engine is operating in a fuel injection mode in which fuel is injected at least from the in-cylinder injection valve, at least the intake passage injection valve performs fuel injection for increasing the supplied fuel. Therefore, the catalyst is reliably prevented from being overheated.
