    摘要：甲醇汽油的推广运用从一定程度上可以缓解能源危机,但由于甲醇汽油的蒸发性,甲醇的引入将增大气阻产生的可能性。虽然低比例的甲醇汽油可以在发动机不做改动的条件下直接使用,但混合燃料的蒸发性有待进一步的研究。本文对几种低比例的甲醇汽油的蒸发性进行了试验研究,结果表面,低比例甲醇汽油的蒸发性变化不大,理论上发动机不易产生气阻。

    Abstract: The popularization of methanol-gasoline could relieve the energy crisis on a certain extent,but the evaporation of the methanol-gasoline has increased the possibility to induce vapor lock.On the other hand,low proportion methanol-gasoline could be used on engine without any modify,and the evaporation of the blends should be researched together.So the research of evaporation on several low proportion methanol-gasoline blends was carried on experimental.The results show that evaporation of low proportion in methanol-gasoline doesn't change greatly,which couldn't induce vapor lock theoretically.
