In order to further strengthen product development and broaden product structure, blended gasoline produced in this plant is taken for basic research object, quality analysis is made on such methanol gasoline fuel as M10, M15 and M20 inthe laboratory and discussed are effects of trace amount water on methanol gasoline fuel. Driving test is made by using vehicle gasoline with methanol,gasoline consumption per100kmand acceleration performance are measured and HC and CO content in tail gas are obtained. Research results show that impurity content in methanol is controlled, M10, M15 and M20 methanol gasoline quality meets the national standards and trace amount water existing in methanol gasoline fuel has no effect on methanol gasoline storage properties and driving safety. 90^＃M10 and 90^＃M20 methanol gasoline fuels have good quality, low consumption per100km, good acceleration performance and less HC and CO content in tail gas, which can reduce environment pollution.
