摘　　要：选用12辆试验样车(一种化油器型发动机和两种电喷型发动机)用含乙醇体积分数分别为7.7%、10%、15%的乙醇汽油和93号标准汽油进行了低、中、高速和山区道路的共8×104km对比行车试验.经试验前后对样车发动机进行拆检和发动机润滑油分析结果表明,燃用乙醇汽油样车的发动机润滑油氧化性能、表面沉积物形成、试验样车发动机主要零部件的磨损与燃用93号标准汽油样车的相当.Ethanol gasoline road tests were conducted with 12 vehicles (1 carburetor and 2 electronic type engines) fueled by ethanol volume contents of 7.7%, 10% and 15% respectively, and compared with the vehicles fueled by 93 # conventional gasoline. The vehicles totally ran 80,000km on low-speed, middle-speed and high-speed roads and mountainous district. Inspection of the engines before and after tests together with the engine oil analyses, the results showed that the oxidation level, surface deposit formation and anti-wear properties of the vehicles fueled by ethanol gasoline were equal to those of the vehicles fueled by conventional gasoline.
