摘要
通过发动机台架试验,对发动机使用93#汽油、E10W93#车用工业乙醇汽油和E20W93#车用工业乙醇汽油的输出功率、扭矩和燃油消耗率进行了测量对比。对发动机使用三种燃料时排气中的CO,HC和NOx浓度进行了测量分析。试验结果表明,在发动机运转条件相同的情况下,乙醇汽油能有效降低发动机的CO和HC排放,但NOx排放比普通汽油要高。
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.
