A hybrid combustion of flame propagation and end-gas autoignition by applying hydrogen addition to low octane number fuel has been successfully demonstrated. Stable lean combustion with significantly low NOx emission and less unburned fuel has been observed. The effects of hydrogen ratio and fuel octane number have been investigated with RCEM experiment, as well as the effect of hydrogen addition to ignition delay time has been studied by using detailed chemical kinetic simulation.
