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.

► We investigate the tribological performance of 2,5-dimethylfuran (DMF) as a potential engine fuel. ► The friction reduction antiwear resistance of blend of gasoline with DMF were varied with the DMF content in gasoline. ► The optimal blend volume for DMF in gasoline is 4 vol% based on the friction reduction and wear resistance of the blends.
