摘要

純廢食用油甲酯燃料(WOME)雖能針對柴油引擎的煙度及HC濃度做有效的改善，特別對煙度的減低，但其油耗(BSFC)比高級柴油燃料增加。又長期使用純廢食用油甲酯燃料對柴油引擎燃料和潤滑系統，以及活塞環等有不良的影響。因此，本研究將廢食用油甲酯(WOME)以不同比例添加在高級柴油(PD)中以減低對廢食用油甲酯(WOME)的使用比例。經引擎性能、油耗及廢氣排放濃度等的實驗，其結果顯示，添加50%廢食用油甲酯於高級柴油中的混合燃料(WOME50)雖可有效的改善油耗(BSFC)及廢氣排放濃度，但引擎性能減低。而添加20%廢食用油甲酯於高級柴油中的混合燃料(WOME20)除能更減低對廢食用油甲酯(WOME)的使用比例外，在不致影響引擎性能的條件下，其油耗(BSFC)及廢氣排放及燃燒特性等均能得到較合理的改善。

The waste fried oil methyl ester (WOME) can improve the concentration of smoke and HC, especially in the concentration of smoke reduction, but the brake specific fuel consumption (BSFC) to compare of premium diesel (PD) has increased. In addition, it has harmful affections on fuel system, lubrication system as well as the piston ring in diesel engines for a long-term use. Therefore, the blending different proportion of WOME with PD can be clarified how much proportion of WOME should be reduced in this study.
Experimental results demonstrated that the BSFC and the concentration of exhaust gas emissions has obviously improved in the blending fuel of 50% WOME with PD (WOME50), but the engine performance has reduced. Using the blending fuel of 20% WOME with PD not only reduce the use of amount of WOME, but also the BSFC, exhaust gas emission and combustion characteristics can be improved more reasonable without influence on engine performance.
