A STUDY OF IGNITION SYSTEM EFFECTS ON POWER, EMISSIONS, LEAN MISFIRE LIMIT, AND EGR TOLERANCE OF A SINGLE-CYLINDER ENGINE--MULTIPLE SPARK VERSUS CONVENTIONAL SINGLE SPARK IGNITION.

The characteristics of multiple spark ignition systems with respect to engine performance, emissions, lean misfire, and tolerance to exhaust gas recirculation (EGR) have been investigated using a carbureted single-cylinder engine. The results, which were compared to those obtained with a standard single spark ignition system, show that both lean misfire limit and EGR tolerance are extended with the multiple spark system. The amount of extension varies with engine load, being largest at the lighter loads studied. Engine power and emissions at non-misfiring conditions are the same with both ignition systems.
