Newly developed Stratified Fuel-Water Injection System was tested for the NO_x reduction on high-speed diesel engine. Compared with ordinary emulsified fuel oil combustion, this system enables to confirm the auto-ignition characteristics under the high water content condition, by means of primary injected pure fuel. Test results show that not only the broad reduction of exhaust NO_x, but also the improvement of B.S.F.C. and smoke density are achieved simultaneously. They also indicate that the exhaust NO_x in high-speed diesel engine could be less than 100 ppm (Excess O_2=13%).
