On the Experimental Research of Ethanol Gasoline Fuels to Gasoline Engine

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 NO_x;(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.
