汽油机燃用乙醇汽油的试验研究

On the Experimental Research of Ethanol Gasoline Fuels to Gasoline Engine

在国内外已有的研究基础上,基于我国国情和现有的使用情况,选用摩托丰汽油机和电喷机,测试乙醇汽油对这两种汽油机的排放、动力性和油耗的影响．试验结果表明：与无铅汽油相比,能明显降低发动机CO和HC的排放,对NO_x排放影响变化趋势并不单一,但是从整体情况来看,NO_x排放又有所降低；电喷机燃用乙醇汽油随乙醇量增大,尾气排放的三种主要污染物有明显下降；摩托车汽油机燃用乙醇汽油总油耗率高于普通无铅汽油3%～5%左右。

Based on the current research in the world and our national and using situation at present, the paper chooses motor gasoline and electronic injection engine to test the influences of emission, power property and consumption of ethanol gasoline on the two kinds of gasoline engine. The results show that,competed to gasoline without lead, （1） whether to electronic injection engine or to motor gasoline engine, ethanol gasoline fuels can obviously reduce the engine emission of CO and HC and its changing tendency to the emission influences on NOx is not single, but as a whole, it can reduce the emission of NOx; （2） to electronic injection engine ,ethanol gasoline fuels enlarge with the amount of ethanol and the three major emission pollutants descend obviously; （3） to motor gasoline engine ,the rate of the consumption of ethanol gasoline is higher about 3 % -5 % than that of the common gasoline without lead.
