On the fundamental lubricity of 2,5-dimethylfuran as a synthetic engine fuel

2,5-Dimethylfuran (DMF) as a new synthesis alternative engine fuel has received much attention in terms of its production and combustion characteristics. However there is a distinct lack of information available on the tribological properties of DMF, and more specifically, its lubricity. In this paper the lubricity of DMF was studied using a four-ball tribometer. The results show that DMF has better antiwear and antifriction properties than commercial gasoline. The lubrication properties of gasoline/DMF blends of 2–20 vol% have been examined in this paper. It has been found that 4 vol% DMF in gasoline is optimal for reducing friction and improving the wear resistance.
