本文介绍了在汽油机上用汽油掺烧酒精的台架试验和行车试验装置,并对试验结果作了分析,结论是:汽油与酒精掺和比 M=10%—17%时,发动机的经济性、动力性均较好;掺和比 M=17%—20%时,发动机的经济性、动力性稍逊,但尚可取。酒精浓度以掺烧88°的酒精时[掺水比 M_1=14.5%],经济性、动力性较好;当掺水比 M_1=15%—20%时,经济性、动力性稍逊,亦尚可取。从节省汽油的角度出发,本文所述试验能以酒精代取10%—20%的汽油。
In this paper, a bench test and driving test device for gasoline blending with gasoline on a gasoline engine are introduced. The test results are analyzed. The conclusion is that the economic efficiency of the engine when the blending ratio of gasoline and alcohol is 10% -17% , The power is better; blending ratio M = 17% -20%, the engine economy, less dynamic, but still desirable. When the alcohol concentration is 88 ° alcohol, the economic and dynamic properties are better than that of the alcohol mixed with M_1 = 14.5%. When the water content ratio M_1 = 15% -20%, the economy and motility are lower Still desirable. From the perspective of saving gasoline, the test described in this article can replace 10% -20% gasoline with alcohol.
