VALVE TIMING CONTROL DEVICE AND POWER OUTPUT DEVICE

摘要

PROBLEM TO BE SOLVED: To optimumly control closing timing of an intake valve at the stop and start of an internal combustion engine and to attain smooth and quick starting of the internal combustion engine. SOLUTION: In this valve timing control device to be used for a power output device provided with a timing adjusting mechanism capable of adjusting closing timing of an intake valve of an internal combustion engine within a prescribed adjusting angle range, a stopping time control means for setting closing timing of the timing adjusting mechanism to a foremost advancing angle position when a stopping of the internal combustion engine is requested, a stopping history determining means for determining whether a stopping operation (an IG.OFF operation, for instance) based on the will of a driver exists or not between starting of previous time and starting of this time when a starting of the internal combustion engine is requested and a starting time control means for setting closing timing of the timing adjusting mechanism to a foremost lag angle position when the internal combustion engine is started.
