高原环境汽油机燃用乙醇汽油的适应性研究

摘要

In the plateau environment, the adaptabilities of E10 ethanol-gasoline and 90# reference gasoline for a truck were compared through road test and bench test. The results show that the power and economy of engine fuelled with E1O ethanol-gasoline slightly improves. The CO and HC emission decrease, but the NO, emission slightly increase.%在海拔2 000～4 000 m的高原环境下,结合汽车道路试验和发动机台架试验,针对某载货汽车进行了燃用E10乙醇汽油与90号标准汽油的适应性对比研究.试验结果表明,燃用E10乙醇汽油后发动机的动力性和经济性均有改善,NOx排放略有升高,而CO和HC排放降低.
