In this study, as a fundamental study for the realization of lean combustion in gasoline engines, compared the ignition performance of traditional ignition methods and an ignition method applying AC power. The experiment simulated the ignition system for the 1.6L gasoline engine from company H, and converted the pulse signal on the supply circuitry inside the inverter into revolutions per minute. With the sparks produced from ignition plugs, energy volume was observed to increase with decreasing air density. As for the AC power ignition system, it was concluded that with the absence of damped oscillation after discharge, it could be used to improve ignition performance.
