摘　　要：为减少对石油的依赖和环境的污染,在不改变汽油机点火提前角特性和供油系的前提下能够在内燃机中使用生物质燃料;用单缸四冲程汽油机对汽油-二甲基呋喃(DMF)以及汽油-醇混合燃料进行了试验研究。研究表明:汽油-DMF的动力性优于汽油-醇。当汽油-醇中甲醇掺混质量分数为10%时输出扭矩最高,但比在DMF掺混质量分数为10%时下降了5.2%;同样,汽油-醇中甲醇掺混质量分数为10%时输出功率最高,比DMF质量分数为10%下降了11.3%;汽油-DMF的油耗率要优于汽油-醇,其中DMF掺混质量分数为10%时在各种转速下油耗率皆最低,而比能耗则稍高于汽油-醇;汽油-DMF的常规排放物总体上低于汽油-醇。In the test conditions without changing the ignition advance angle and the fuel supply system, the performance characteristics of gasoline-2,5-dimethylfuran （DMF） blends and gasoline-alcohol blends were investigated in a gasoline internal combustion engine using biomass fuel to reduce dependence on oil and impact on environment. Tests show that the power performance of gasoline-DMF blends is superior to that of gasoline- alcohol blends. Compared with using gasoline-DMF blends with DMF mass proportion of 10%, the maximum output torque and output power decrease by 5.2% and 11.3% when using the gasoline-alcohol blends with methanol mass proportion of 10%; the fuel consumption rate of gasoline-DMF blendsis superior to gasoline-alcohol blends and that of blends with DMF mass proportion of 10% is lowest at different rotate speeds. But the energy consumption rate of gasoline-DMF blends is larger than that of gasoline-alcohol blends. Traditional legislated emissions of gasoline- DMF blendsare less than that of gasoline-alcohol blends as a whole.
