Beschreibung
Zusammenfassung:	A control apparatus for an internal combustion engine, which, in the case of intake-side and exhaust-side cleaning controls being performed, is capable of ensuring stable combustion of a mixture when the engine is returned from a decelerating FC operation to a normal operation, thereby making it possible to enhance marketability. The control apparatus for the engine includes an ECU. The ECU performs intake-side cleaning control for controlling an intake cam phase CAIN to a predetermined most advanced value CAIN_ADV so as to increase a valve overlap period of an intake valve and an exhaust valve, and performs exhaust-side cleaning control for controlling an exhaust cam phase CAEX to a predetermined most retarded value CAEX_RET so as to increase the valve overlap period of the intake valve and the exhaust valve. Further, during execution of one of the intake-side and exhaust-side cleaning controls, the ECU inhibits execution of the other.
