摘要
低比例的乙醇汽油已经在部分省市得到了推广运用,但由于乙醇的蒸汽压低,气化潜热大,增加了发动机气阻产生的可能性。为了解乙醇汽油的蒸发性,本文主要对几种不同混合比例的乙醇汽油进行了馏程和饱和蒸汽压试验研究。通过试验可以看出,低比例的乙醇汽油蒸发性得到一定程度的提高,而高比例的乙醇汽油其蒸发性变化幅度较大。对进一步研究和推广运用乙醇汽油有一定指导意义。
Low proportional ethanol-gasoline has already been popularized and used in some provinces and cities. The possibility of vapor lock was increased on engine because the low saturated steam pressure and the great latent heat of gasification. In order to study the evaporation of ethanol-gasoline, experimental investigations had been carried out on distillation range and saturated steam pressure to several different ethanol-gasoline blends. Results indicate that, the evaporation of low proportional ethanol-gasoline doesn＇t increase much and the evaporation of high proportional blends changes relatively largely. This paper offered certain directive significance to further studying and popularizing the ethanol-gasoline.
