阐述了在高原地区进行汽油机掺烧含水乙醇的试验研究,着重介绍了掺烧50%的含水乙醇的汽油对汽油机的经济性、动力性的影响。还进行了怠速排放对比试验的研究。试验结果表明,此比例的混合燃料的稳定性良好；能够保持发动机的原机动力性；有效燃油消耗率有一定的上升,但不是十分明显；当量燃油消耗率明显低于原机水平,提高了原机的经济性；有效热效率相对于原机有了不同程度的提高；怠速工况CH和CO的排放有所改善。
The experimental research on gasoline blending with ethanol in the plateau is described. The effects of gasoline blending with 50% ethanol on gasoline economy and dynamics are also introduced. A study was also conducted on the comparison of idling emissions. The test results show that the ratio of the mixed fuel stability is good; can maintain the original engine motility; effective fuel consumption rate increased a certain, but not very obvious; equivalent fuel consumption was significantly lower than the original level, increased The economy of the original machine; Effective thermal efficiency relative to the original machine has improved to varying degrees; idle conditions CH and CO emissions have improved.
