在用柴油公交车燃用生物柴油的试验研究

Experimental Research of In-used Diesel Bus Fueled by Biodiesels

对上海在用国Ⅱ柴油公交车燃用石化柴油─废弃油脂制生物柴油混合燃料的经济性、动力性和排放性能进行了试验研究。试验结果表明,在用国Ⅱ柴油公交车燃用BD5的燃油经济性与柴油公交车基本相同,最大轮边功率降低约2%,加载减速法烟度平均降低约17%;燃用BD10的燃油经济性比柴油公交车略差,最大轮边功率降低约4%,加载减速法烟度平均降低约35%。

Experimental research on fuel economy, power, and emission performances of petro diesel - a biodiesel blend made of waste grease used in China Ⅱ diesel bus of Shanghai were carried out. The experimental result showed that fuel economy of BD5 fueled in-used bus is almost identical with that of conventional diesel bus,the maximum wheel power of BD5 reduces by about 2%,and its lug-down smoke emission reduced by about 17%.Moreover,the fuel economy of BD10 fueled in-used bus is slightly inferior to that of conventional diesel bus,the maximum wheel power of BD10 reduces by about 4 %,and its lug-down smoke emission reduced by about 35%.
