The Research Progress of Diesel Lubricity and Anti-wear Additive

The lubricity of low sulfur diesel fuels tends to be poor due to deep desulfurization. This paper summarizes the influence factors on the lubricity of diesel fuels,wear mechanism and lubricity additives,among them the ester is ideal lubricating additive for low sulfur diesel fuel because of its good lubricity. Besides,it brings forward some suggestion to the further research on diesel lubricity.
