摘要

1997年京都國際會議議定書交付給各工業先進國家要將他們對地球排放的溫室氣體(CO2)，應在2008-2012年時要減少1990年排放CO2量的5％，由此開始歐盟各國政府紛紛開始贊成使用生質能源作為柴/汽油引擎的替代燃料。本研究採用歐盟各國使用最為普及的菜籽油及菜籽油甲酯生質燃料，來探討柴油引擎性能、油耗、廢氣排放和燃燒特性等。經引擎實驗結果顯示，菜籽油甲酯燃料(ROME)在不影響引擎性能的情形下，與純高級柴油燃料(PD)相比，其油耗及NOX濃度稍差，分別增加14.52%和26.06%，但對煙度及HC濃度排放的改善頗具效果，分別減少50.40%以及 45.98％。而菜籽油添加去漬油的混合燃料(RO50NF50)雖在引擎性能方面略遜，但與PD燃料相較，除油耗微高8.71%之外，在廢氣排放濃度均有優異的表現，尤其以HC濃度減少78.58%，而Smoke濃度和NOX 濃度則分別減少45.79% 和7.93%。

At 1997, the Kyoto Protocol on International Convention that requested the industrialization and developed country formally to follow the criterions at 1990 for the amount of 5% decreased on the global atmospheric concentrations of CO2 in 2008 to 2012. 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.
