ABSTRACT:
An engine control system and method wherein the peak pressure in the combustion chamber can be reduced without significantly reducing engine output by supplying fuel in two segments. The first segment is begun before combustion begins and the second segment is not initiated until after combustion has been initiated and preferably after peak pressure has occurred in the combustion chamber. In this way, incipient knocking can be controlled without adversely effecting the engine performance.
