Abstract

An adaptive control circuit for use with a machine performance optimizing system for producing a control delay between a first event and the time at which a response to that event is to take place. The adaptive control circuit of this invention, when used with an internal combustion point closure signal and will advance or retard the generation of a spark plug firing signal for a period determined by the optimizing system's operating parameters, while still maintaining the desired dwell dictated by the engine manufacturer.
