Newly developed Stratified Fuel-Water Injection System was tested for the NOx 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 NOx, but also the improvement of B.S.F.C. and smoke density are achieved simultaneously. They also indicate that the exhaust NOx in high-speed diesel engine could be less than 100 ppm (Excess O2=13%).
