摘要

廢食用油甲酯的動力黏度和密度等皆高於其他食用植物性油脂，本研究使用WOME20廢食用油甲酯生質柴油在不同燃料噴射壓力的直噴式柴油引擎上使用下，經引擎性能實驗結果顯示，使用較低的燃料噴射壓力時約可分別改善燃料消耗率5％、煙度15%和HC16%的廢氣排放濃度外，又可減低引擎的廢氣排放溫度約0.5％使引擎性能提高，但廢氣排放中的NOx濃度值約增加7％。由此可證，使用WOME20廢食用油甲酯生質柴油時，可將直噴式柴油引擎的燃料噴射壓力減低約40kg/cm2，即可有效的改善柴油引擎性能、油耗和廢氣排放等優點。

Kinetic viscosity and density of Waste Oil Methyl Ester is higher than others edible vegetable oil, the research used WOME20 at DI Diesel Engines with Biodiesel Waste Oil Methyl Ester at different Fuel Injection Pressure, according to the Engine Performance shows that the lower Fuel Injection Pressure will improve Concentration of Exhaust Gas Emission, BSFC 5%、smoke 15% and HC 16%. Not only improve the Concentration of Exhaust Gas Emission but also lower the temperature about 0.5%, Engine Performance will be risen, but the NOx in Concentration of Exhaust Gas increase about 7%. Therefore, using WOME20 Biodiesel can lower DI Diesel Engines Fuel Injection Pressure 40kg/cm2, then effect Engine Performance, Fuel Consumption and Concentration of Exhaust Gas Emission.
