Ignition and combustion by Pulsed Combustion Jet (PCJ) at high pressures and temperatures were investigated using a compact rapid compression machine. The compression and stop motion of a compression piston in the rapid compression machine is controlled by the cam shape, and the cam is operated by a driving piston and compressed air. The combustion process was monitored by pressure measurements and high-speed schlieren photography. Lean limit of methane-air mixture was extended by PCJ, and the superiority of PCJ over standard spark ignition was demonstrated in enhancing the process of combustion in turbulent lean mixtures.
