进行了柴油机燃用B5生物柴油的1 000 h可靠性台架试验,测量了可靠性试验前后发动机的燃油消耗、机油消耗、功率、扭矩、活塞漏气量、排气温度等参数,进行了发动机润滑油的色谱分析以及发动机的主要零部件的拆检和分析.试验结果表明:可靠性试验后发动机的燃油消耗和机油消耗均有所增加,活塞漏气量有所升高,功率、扭矩和排气温度略有下降;B5生物柴油与柴油的CO等气体排放相差不大;发动机喷油器、气门、活塞顶面等主要零件部存在积碳,活塞环与气缸套等零件磨损正常.

The 1000-hour reliability bench test of diesel engine fueled with B5 biodiesel was completed. The engine parameters such as fuel consumption, lubricant oil consumption, power, torque, piston leakage volume and exhaust temperature before and after the reliability test were measured. The lubricant chromatographic analysis was made, and the main engine parts were disassembled and analyzed. The results showed fuel consumption and oil consumption increased slightly after the reliability test, and the power, torque and exhaust temperature decreased at different degrees while the piston leakage volume increased. The difference of gas emission such as CO between B5 biodiesel and diesel was not too big. The engine lubricating oil contained unsaturated fatty acid methyl ester and aroused lubricant metamorphism. Some carbon deposition exised in the fuel injector, valve and piston, and shadow scratch existed in piston skirt and piston ring attrition normally.
