Abstract
An ignition advance timing system for generating the ignition signal or the injection signal in an engine utilizes both the advantages of an angular-based system and a time-based system. A tooth wheel (10) operatively connected to the crankshaft of the engine (26) having groups (14) of teeth (16, 22, 24) positioned thereon. Each group represents the angular range of ignition or injection for a particular cylinder. The angular space (29) between each group of teeth allows a microprocessor (12) to begin a computing period (36) free of any interrupt signals generated by the teeth in the wheel. The microprocessor determines the desired angle which is synchronized with the teeth in the wheel to find the closest advance angle and by means of a timer the desired angle is generated.
