Numerical and experimental study of passive pre-chamber turbulent jet ignition on Wankel engine

AIP Conference Proceedings
This study aims to increase the flame speed in the Wankel engine by using turbulent jet ignition. The Wankel engine suffers from poor exhaust emissions and high fuel consumption due to insufficient combustion speed and the inability to spread the flame throughout the shallow structured combustion chamber.
