车用M85甲醇烃类燃料的发动机性能试验研究

Research on Performance of Gasoline Engine Operating on M85 Methanol-hydrocarbon Fuels

本文介绍了一种醇烃燃料的制备方法,并对该醇烃燃料的排放特性、速度特性和负荷特性进行了试验研究,探讨了内燃机燃烧该醇烃燃料和92#汽油在动力性、经济性和尾气排放三个方面的差异。研究结果表明,和92#汽油相比,该醇烃燃料的最大输出功率略有增加：耗油率增加了5.5%-6.0%,尾气中CO含量下降了95%-96.3%、HC含量上升了24%-27%。因此,从较低成本、CO含量降低等角度分析,该醇烃燃料可以部分或完全替代汽油。

This paper introduced a preparation method of methanol-hydrocarbon fuels. The fuel emission characteristics, speed characteristics and load characteristic were experimentally studied. The performances of power, fuel economy and exhaust emission of combusting the methanol-hydrocarbon fuels and 92# gasoline was analyzed. The results show that compared with 92# gasoline, the maximum output power of methanol-hydrocarbon fuels increased slightly： the fuel consumption increased by 5.5% - 6.0%, the CO content in exhaust gas decreased by 95% - 96.3%, and the HC content increased by 24% - 27%. Therefore, considering of the low cost and low CO emission, the methanol-hydrocarbon fuels can partially or completely replace gasoline fuels.
