Beschreibung
Zusammenfassung:	A control unit for an internal combustion engine is configured for suppressing knocking phenomenon with reduction of overlap, while maintaining an opening timing of an exhaust valve at the time of low-rotation, high-load state. A valve opening/closing timing control apparatus includes a phase adjustment mechanism configured to vary a relative rotational phase between a driving side rotary body rotatable in synchronism with a crankshaft of the internal combustion engine and a driven side rotary body rotatable together with an exhaust cam shaft. After an opening timing of the exhaust valve, an advancing operation is effected for displacing the relative rotational phase in the advancing direction relative to the opening timing.
