In this study, LSD (Shanghai IV low sulfur diesel), HSD (China II diesel), Emulsified LSD (10% of water with 90% Shanghai IV diesel by volume) and Emulsified HSD (10% of water with 90% China II diesel by volume) were tested in a high-pressure common rail diesel engine to investigate the power performance, fuel economy and emission characteristics of the engine. The study shows that there is small impact on power performance of the diesel engine fueled with four tested fuels. The China III diesel engine fueled with LSD has better power performance, fuel economy and lower PM emissions than HSD. When the China III diesel engine was fueled with four tested fuels, CO, HC, NOX and PM emissions could meet China III emission standards, but could not fully meet China IV emission standards. It is more efficient to reduce CO, HC, NOX and PM emissions when engine is fueled with emulsified diesel than neat diesel. Compared Emulsified HSD with HSD, the decreases were, 3.92%, 7.14%, 2.22% and 21.02% respectively for PM, CO, HC and NOX emissions of the tested engine, while compared Emulsified LSD with LSD, the corresponding decreases were 17.31%, 10.71%, 7.22% and 15.82% respectively.
