摘要：针对乙醇汽油混合燃料,采用E0-E50进行了发动机台架怠速试验研究。基于实验数据,运用模糊数学理论,建立了掺醇比与发动机经济性、排放性之间的模糊关系,并对不同掺醇比的经济性、排放性做出模糊综合评判,优化出汽油机怠速时最佳掺醇比为E20。

Abstract: In terms of the ethanol
gasoline blend,bench test and research for E0-E50 fuel are done on the idle
speed engine.On the basis of the experimental data,fuzzy relation among bend
ratio,engine economy and emission is established by the fuzzy mathematic
theory.A comprehensive fuzzy evaluation is given to economy and emission of
ethanol-Gasoline blend at different blend ratio.It is concluded that E20 blend
is most optimal when gasoline engine is operating at idle speed.
Keywords: Fuzzy Evaluation;Gasoline
