In this study, premixed compressed ignition and high temperature diffusion combustion were combined to reduce the emissions of soot and NOx simultaneously in a diesel engine.To establish the combustion methods, we applied two-stage injection. The premixed combustion was ignited in the lststage of the injection without emissions of soot and NOx and then a high temperature field was created.This achieved the high temperature diffusion combustion in the 2nd stage of the injection with very low emission of soot and NOx. As a result, PM and NOx were much more reduced simultaneously compared to conventional combustions.
