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。

Abstract:

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 gasolinealcohol
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.

Key words: 2,5-dimethylfuran (DMF), gasoline-DMF blends, gasoline-alcohol blends, traditional legislated emissions
