Summary: | 碩士 === 國立虎尾科技大學 === 機械與機電工程研究所 === 98 === The only self-contained biodiesel source includes waste oil methyl ester biodiesel about 150,000 tonnes per year. Even though the biodiesel blended fuel was used around the world, the mixed proportion of biodiesel still doesn’t have the best common standard. Therefore, this study used different mixed ratio of biodiesel in fossil super diesel to explore the best adding ratio of biodiesel blended fuel, which will affect engine performance, fuel consumption, the exhaust emissions and the fuel properties. The results of dynamometer indicated that B20 biodiesel blended fuel have higher than engine performance and lower than fuel consumption and exhaust emissions than other adding ratio’s biodiesel blended fuel. Therefore, the characteristic of combustion is much more ideal.
