At this point of view, every government of European Union has begun to approve of using biomass energy to be alternative fuels for diesel/gasoline engine. In this study, the rapeseed oil and rapeseed oil methyl ester which is adopted as investigating the performance of diesel engine, BSFC, exhaust gas emissions and the combustion characteristics, are used popularly in the country of European Union. Experimental results demonstrated that using ROME which is based on no influence of engine performance has higher BSFC and the concentration of NOX than PD 14.52% and 26.06%, respectively. But the concentrations of Smoke and HC are obviously decreased 50.40% and 45.98%, respectively. Furthermore, the blending fuel (RO50NF50) which is blended by the rapeseed oil with naphtha is slightly worse of engine performance and higher BSFC 8.71% than PD. But each of the exhaust gas emissions is well improved, especially for HC decreasing 78.58%, and the concentrations of Smoke and NOX are decreased 45.79% and 7.93%, respectively.
