(57) A multiple-spark electronic ignition system producing a timed sequence of a plurality of ignition sparks per cylinder compression cycle of an internal combustion engine. The system includes: a trigger pulse signal source; a control circuit that generates a plurality of timed ignition signals for each of the trigger pulses, preferably 3 to 20 signals, the frequency of the timed ignition signals being a function of the RPM of the engine; and an amplifying circuit which transforms the timed sequence of ignition pulses into a timed series of high energy ignition sparks.
