摘　　要：分别开展了92#汽油、E15乙醇汽油、M15甲醇汽油台架试验、污染物排放试验,对比了相同添加比例的2种醇类汽油与92#汽油的车辆应用性能。结果表明,E15乙醇汽油与M15甲醇汽油的速度特性、负荷特性差别不明显。在2500~3500 r/min时,E15乙醇汽油与M15甲醇汽油的功率、转矩与92#汽油相当;在4000~5000 r/min时,相比于92#汽油,E15乙醇汽油与M15甲醇汽油的功率、转矩均出现明显下降;油耗方面,在2500 r/min时,相比于92#汽油,E15乙醇汽油和M15甲醇汽油的平均燃油消耗率分别升高了3.5%左右和3.1%左右;大多数工况下,2种醇类汽油对CO、HC排放均有较大改善,E15乙醇汽油对CO的怠速排放改善明显,M15甲醇汽油对HC的怠速排放改善明显。The bench test and pollutant emission test of 92#gasoline,E15 ethanol gasoline and M15 methanol gasoline were carried out respectively.The vehicle application performance of two alcohols and marked 92#gasoline with the same addition ratio was compared.The results indicated that the speed characteristics and load characteristics of E15 ethanol gasoline and M15 methanol gasoline were not obviously different.Meanwhile,compared with the 92# gasoline under the same working condition,the power and torque of E15 ethanol gasoline and M15 methanol gasoline were the same as that of 92# gasoline at 2500-3500r/min.However,both power and torque decreased significantly at 4000-5000r/min.In terms of fuel consumption,when the rotating speed is 2500r/min,the average fuel consumption rate of E15 ethanol gasoline increased by about 3.5%,and that of M15 by about 3.1%.The emissions of CO and HC compounds were significantly improved by the two ethanol fuels under the majority of operating conditions.The low idle emissions of CO and HC were dramatically improved by E15 ethanol gasoline and M15 methanol gasoline,respectively.
