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 the temperature of a component located in the exhaust passage is higher than or equal to a predetermined temperature. When the temperature of the component is higher than or equal to the predetermined temperature, the control apparatus increases, without changing the total amount of fuel supplied to the cylinder, the ratio of a fuel injection amount of the intake passage injection valve to a fuel injection amount of the in-cylinder injection valve compared to a case where the temperature of the component is not higher than or equal to the predetermined temperature. Therefore, the catalyst is reliably prevented from being overheated, while preventing the fuel economy from deteriorating.
