Newly developed Stratified Fuel-Water Injection (SFWI) System was tested for the NO_x reduction on low-speed 2-cycle diesel engine. Compared with the ordinary water addition combustion system such as emulsified fuel oil combustion, this system enables to confirm the auto-ignition characteristics under the high water content condition, by means of the primary injected pure fuel. Test results show that the multi-layer stratified spray construction is effective to achieve the high NO_x reduction ration such an extent to 50% with minimum B.S.F.C. penalty of 1.5%. The combustion Characteristics of SFWI on low-speed diesel are also examined.
