低比例甲醇汽油气阻研究进展

论述了低比例甲醇汽油气阻问题产生的原因及目前研究进展。结果表明：低比例甲醇汽油气阻是制约甲醇汽油推广的关键因素之一；目前解决气阻的途径有：催化改性；气阻指数和气阻温度控制；甲醇与汽油组分分子反应；基础汽油复配；添加气阻抑制剂等，各研究都在一定程度上解决了气阻问题。

Discusses the vapor lock problem of low ratio of methanol gasoline blends and the present research progress. The results show that the vapor lock low proportion of methanol gasoline blends is one of key factors restricting promotion of methanol gasoline, solving manners:catalytic modification; The vapor lock index and the temperature control of vapor lock; Methanol and gasoline internal molecular reaction; Based on gasoline distribution;Add a vapor lock inhibitors, etc., all research to a certain extent, have solved the problem of the vapor lock.
