Study on the Ethanol Gasoline by Engine Bench Test

Through the engine bench test, the output power, torque and fuel consumption rate of the engine have been measured and contrasted, with 93# gasoline, E10W93# industrial ethanol gasoline for vehicle and E20W93# industrial ethanol gasoline for vehicle. Moreover, the concentration of CO, HC and NOx which are emitted from the three types of fuel consumption has been measured and analyzed. The results indicate that, in the same circumstances of engine operating conditions, the ethanol gasoline can effectively reduce the CO and HC emissions, but the NOx emissions are higher than that of ordinary gasoline.
