Abstract

Digital dwell circuitry for a spark-and-dwell ignition control system uses maximum advance and reference sensors to produce pulse transitions, which determine positions for the maximum and minimum possible advances for spark ignition with respect to the position of the engine crank-shaft. For each maximum advance sensor pulse transition, a main counter starts a sequential running count of speed-independent clock pulses wherein the maximum count obtained by the counter is related to the engine crankshaft speed. The main counter running count also determines several inputs to a read-only memory (ROM) circuit whose output controls a rate multiplier.
