The relationship between fuel lubricity of diesel(wear values tested using the High Frequency Reciprocating Rig) and the wear of plunger matching parts was evaluated using SRV wear machine.The results show that the plunger matching parts lubricated by low lubricity diesel containing litter sulfur (S content ≤500 μg/g) is badly worn,and there is no relativity between lubricity of litter sulfur diesel and the wear values of plunger matching parts.High sulfur and low lubricity diesel has relatively higher bearing capacity,the plunger matching parts lubricated by it has light wear,and there is good relativity between lubricity of high sulfur diesel and the wear values of plunger matching parts.With moderate amount of acidic components,it is helpful for improving bearing capacity and lubricity of diesel.The SRV test does not appear serious wear for parts of high sulfur diesel produced from direct distillation technique due to the amount of acidic components and high viscosity,even though they have a poor lubrication in HFRR test.
