Abstract Medium molecular fraction, the boiling point range of which is 80～200 ℃ from the upgraded product, was simulated by typical model oil. On one single-cylinder and four-stroke gasoline engine, a series of combustion tests of model oil, model oil-gasoline blends, and gasoline were conducted. Results show that when only fuel supply is added by adjusting the structure of carburetor, the dynamic performance of burning model oil has a slight decrease less than 5%, and the rate of energy expenditure decreases by 8.47% compared to gasoline. HC and CO emissions using model oil obtain an obvious decrease of 42.97% and 66.7%, while NOX and CO2 emissions acquire a rise of 29.47% and 20.17%, respectively. For blended fuels, the volume fraction of model oil is 10% (B10) or 20% (B20), and the performances of gasoline engine act between the model oil and gasoline when no adjustments are made to the engine.

超临界乙醇提质生物油的汽油机试验研究
配制了典型的模型油模拟提质产物中的中质成分（沸点为80～200 ℃）,在1 台单缸4 冲程汽油机上对模型油、模型油-汽油混合燃料及汽油进行试验研究.结果表明：调整化油器结构适当增加供油量,在不改变发动机其他特性的条件下,燃用模型油的动力略微下降,下降幅度在5%以内,能耗率平均下降了8.47%；HC和CO排放远远低于汽油,平均下降了42.97%和66.7%,但NOX和CO2排放明显上升,相对汽油平均分别上升了29.47%和20.17%.对汽油机不作任何调整,燃用模型油体积分数10%（B10）和20%（B20）的混合燃料的动力特性及排放特性一般介于汽油与模型油之间.
