ABSTRACT:
Several embodiments of valve timing control for internal combustion engines so as to improve the engine performance in response to sensed characteristics. In addition, the valve timing is also changed either to avoid knocking in incipient knocking conditions or to stop knocking once it has occurred. Both normally aspirated and supercharged versions are described.
