摘要

由於葵花油在所有植物性可食用油脂中的含油脂率最高，又是高經濟價值的能源作物之一，因此，本研究將使用葵花油和已甲酯化的葵花油甲酯生質柴油為實驗的用油，經引擎性能實驗後，其所得之結果顯示，葵花油甲酯生質柴油在燃料消耗率上雖高於超級柴油約10.97%，但引擎性能幾乎無影響，另在廢氣排放上，除NOx 濃度值較超級柴油高約13.07％外，其他smoke和HC濃度值均分別比超級柴油低約52.44%和19.08%。此外，葵花油添加去漬油的混合燃料雖然在引擎性能表現上略遜外，又燃料消耗率、NOx濃度和排氣溫度則分別高於超級柴油約 11.34％、0.55％和8.73％，但在smoke和HC排放的濃度值上均分別較超級柴油低約36.83 %和15.01 % 。因此，使用葵花油甲酯生質柴油做為柴油引擎的替代性燃料是值得考慮推廣的。

The sunflower oil and sunflower oil methy ester biodiesel are operated in the study, because sunflower oil has richest fat among edible fat of the plant and it also has high economic value in one of the energy plant. After engine performance experiment, it is demonstrated that BSFC of sunflower methyl ester bio-diesel is higher than premium diesel about 10.97%, but almost no influence in engine performance. For the exhaust gas emissions of sunflower oil methyl ester biodiesel, only the concentration of NOx is higher than premium diesel about 13.07%, but the concentrations of smoke and HC are lower than premium diesel about 52.44% and 19.08%, respectively. Besides, another experimental blend fuel which is blended by the sunflower oil with naphtha has just a little bit of lower engine performance, and its BSFC, the concentration of NOx and exhaust gas temperature are higher than premium diesel about 11.34%, 0.55% and 8.73%, respectively. But the concentrations of smoke and HC are lower than premium diesel about 36.83% and 15.01%. Therefore, using sunflower oil methyl ester biodiesel to be an alternative fuel in diesel engine is very worthy of consideration and being popularized.
