Abstract

Maximum advance and reference sensors are utilized to produce pulse transitions which determine positions of max. and min. possible advance for spark ignition w.r.t the position of the engine crankshaft. 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 engine crankshaft speed. The running and maximum counts of the main counter are utilized by dwell circuit to determine the time prior to the next maximum advance pulse at which spark coil excitation should occur.
