Abstract
An electronic fuel injection system for an engine with a self-triggered ignition system is provided with means for detecting the time interval between two adjacent voltage signals which are induced before and after an ignition signal in a primary winding of the ignition coil, and have a polarity opposite that of the ignition signal. The latest two time intervals which have been detected are compared to each other, and according to the comparison result, one of said two voltage signals is determined as a specific signal for obtaining a fuel injection timing.
