This study was aimed at reducing Soot and NOx by uniform and lean distribution of fuel in diesel spray using high-pressure fuel injection and a micro-hole nozzle. But this injection system made ignition delay shorter. So that, it couldn't completely make uniform and lean distribution of fuel in diesel spray. Then, in addition to this injection system, using low cetane number of fuel, which can not easily ignited, we made ignition delay longer, and attempted to make complete uniform and lean distribution of fuel in diesel spray. The combustion event was observed by high-speed direct photography, ignition and combustion was analyzed by the combustion chamber pressure history, and KL values and flame temperatures was analyzed by the two-color method from the two dimensional flame image.
