| Summary: | 碩士 === 國立臺北科技大學 === 車輛工程系所 === 95 === The peanut oil is very rich of high fat and high economic value of biodiesel in the plant oil. Therefore, the peanut oil methyl ester bio-diesel that is made by esterification is used in this study. After engine performance experiment, it is shown that BSFC of peanut oil methyl ester bio-diesel is higher than premium diesel about 13.56% and almost no influence in engine performance. For the exhaust gas emissions of peanut oil methyl ester biodiesel, its concentration of NOx is higher than premium diesel about 19.5%, but the concentrations of Smoke, HC are lower than premium diesel about 60.77% and 28.50%, respectively. Although the blending fuel (PE50NF50) which is blended by the peanut oil with naphtha has lower engine performance, and higher BSFC than premium diesel about 7.65%, but the concentrations of Smoke、NOx and HC are lower than premium diesel about 40.53%、12.68% and 55.97%, respectively. Experimental result demonstrated that using peanut oil methyl ester biodiesel or the blending fuel (PE50NF50) to be an alternative fuel in diesel engine is very worthy of consideration and being popularized.
