E10乙醇汽油在通用小型汽油机中的应用研究

Study on Application of E10 Ethanol Gasoline in Universal Small Gasoline Engine

在非道路用车辆中使用的通用小型汽油机未做调整的情况下,试验研究了燃用E10乙醇汽油对发动机动力性、经济性及排放性的影响。试验结果表明,通用小型汽油机燃用乙醇汽油后,动力有所下降,但下降幅度不超过5%;与93#标准汽油相比,中小负荷下乙醇汽油的燃油消耗率有所增加,而大负荷时与汽油基本持平;按照EPA排放法规对其比较排放性,发现乙醇汽油在满足法规要求的情况下,CO有所下降,而HC,NOx有所增长。

This paper experimentally investigates the power, economy and emission performance of non-road small gasoline engine fueled with E10 ethanol-gasoline without adjustment. The results show that power of engine decreases at partial,but it doesn＇ t exceed 5%. The brake specific energy consumption of EIO ethanol-gasoline is bigger than that of 93^# standard gasoline under middle and low load, but it is almost same under high load. When E10 ethanol-gasoline is used as fuel for engines, the emission level can meet EPA emission regulation, but CO decrease, HC and NOx increase than those of engine fueled with gasoline.
