应用微乳化理论研制E10含水乙醇汽油乳化剂,在电喷发动机上进行燃用E10含水乙醇汽油对发动机动力性、经济性和排放性的影响试验研究.试验结果表明:基于HLB值理论配制的SPY乳化剂能较好地解决E10含水乙醇汽油的稳定性问题；发动机燃用E10含水乙醇汽油后,动力性略有降低,有效燃油消耗率略有升高,能源消耗率降低；怠速排放的CO、HC、NOx均下降,NOx下降幅度达到65％；多工况排放的CO、HC在低负荷略有降低,中高负荷时明显降低,CO降低9％ ～ 17％,HC降低4％～9％；NOx在中小负荷时降低12％左右,大负荷时改变不明显.%Emulsifier of E10 hydrous ethanol gasoline was developed based on micro-emulsion theory; the impact of E10 hydrous fuel on engine power, economy and emissions of electronically controlled SI engine was experimentally investigated. The results showed that; Emulsifier made on the base of HLB value theory can solve the stability problems of E10 fuel; When fueled with hydrous micro-emulsion E10 ethanol gasoline, engine power was reduced slightly, fuel consumption rate increased slightly, energy consumption was reduced; Emissions at idle speed were improved significantly, CO, HC, NO, emissions decreased, Nox decreased the most significantly by 65 %. According to various conditions emissions, CO, HC emissions decreased slightly under small load, decreased significantly in large load, CO decreased by 9% ~ 17% , HC 4% ~9% ; Nox decreased by about 12% in the small load, and didn't obviously change in large load.
