    摘要：在高原地区开展了燃用含水乙醇/汽油混合燃料的试验研究。在汽油机上进行了纯汽油与掺比为10%含水乙醇(95%浓度)/汽油混合燃料的动力性、经济性和排放性能的对比试验。试验结果表明,E10混合燃料的稳定性良好;燃用E10含水乙醇/汽油混合燃料后,能保持发动机的原机动力性;在较低转速内,有效燃油消耗率有一定的上升,随着转速和负荷的提高,有效燃油消耗率的上升状况得到较好的改善;当量燃油消耗率明显低于原机水平;有效热效率得到不同程度的提高;怠速工况的CH和CO的排放有所改善。

    Abstract: An experimental study is carried out on hydrous ethanol/gasoline compound combustion on the.Plateau.The comparative experiments on performance of power,economy and emission are done between pure gasoline and ethanol/gasoline blends of 10% hydrous ethanol(95%) on the gasoline engine.The results show that,E10 blended fuel is steady;It can keep the performance of power after E10 hydrous ethanol/gasoline blending on gasoline engine;At lower speed range the specific fuel consumption is up to a certain extent,the ascending status of specific fuel consumption is better improved following the rise of engine speed and load;The equivalent specific fuel consumption is much lower than the original machine level;Effective thermal efficiency gets increased at different levels;The emission of CH and CO at idle operating modes is improved.
