ABSTRACT:
A system for controlling a valve mechanism for an internal combustion engine has a valve timing device for changing the valve timing of an exhaust valve of the engine, and a changing device for changing the opening duration of an intake valve of the engine. A detector is provided for detecting a cold engine state and for producing a cold engine signal. In response to the cold engine signal the valve timing device operates to advance the opening timing of the exhaust valve and to reduce the opening duration of the intake valve.
