Abstract

HCCI combustion has a disadvantage in controlling ignition timing. In this study, we applied Pulsed Flame Jet (PFJ) to HCCI under Exhaust Gas Recirculation (EGR) conditions. PFJ is the jet of burning gas issuing from a small cavity facing a combustion chamber. It is expected to advance autoignition. On the other hand, EGR leads to the retard of autoignition. Thus combining PFJ and HCCI may lead to the optimization of ignition timing. The experiments were performed with a rapid compression expansion machine. With PFJ, the indicated work under EGR conditions was improved by optimizing the timing of spark discharge of PFJ.
