CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE

It is intended to suppress formation of any excessive rich air-fuel ratio of the air-fuel mixture caused by adhered fuel on an inner wall surface of an intake passage of an internal combustion engine. A throttle valve driving unit is controlled so that if a variation amount of decrease in output of...

Beschreibung
Zusammenfassung:	It is intended to suppress formation of any excessive rich air-fuel ratio of the air-fuel mixture caused by adhered fuel on an inner wall surface of an intake passage of an internal combustion engine. A throttle valve driving unit is controlled so that if a variation amount of decrease in output of the internal combustion engine exceeds a predetermined variation amount when the output of the internal combustion engine is smaller than a predetermined output in a non-warm-up state in which the temperature of the internal combustion engine is equal to or lower than a predetermined temperature, then an opening degree of the throttle valve becomes a predetermined increased opening degree which is increased as compared with a standard opening degree as an opening degree of the throttle valve to be provided if the variation amount does not exceed the predetermined variation amount. Further, the electric power generated by a generator is stored in an electricity storage apparatus corresponding to increase in output of the internal combustion engine based on an amount of increase from the standard opening degree to the predetermined increased opening degree.
