Misfire and knock detection based on the ion current inside a passive pre-chamber of gasoline engine
Fuel, 2022Abstract In this study, a novel idea of capturing ion current signals inside the passive pre-chamber is proposed. The signals were analyzed in terms of various operating conditions based on a naturally aspired gasoline engine. Under normal combustion, the chemical and the thermal ionization peak's phase difference is much smaller than the commercial ...
