Summary:

AbstractLubricity is an empirically-determined tribological property, which is a function of the fluid properties and system, and which is known to influence fuel system wear durability. In this work, the lubricity of various fuels was tested using a modified version of ASTM D6079, which uses a high frequency reciprocating rig (HFRR). The fuels were tested as received and with various amounts of commercial diesel lubricity additives. Lubricity of all light-end fuels test as received (without lubricity additives) was found to be substantially worse than additized diesel certification fuel, and lowest for unadditized straight-run gasoline. All diesel lubricity additives tested were able to substantially improve the lubricity of the light-end fuel formulations. The best additives reduced the wear scar diameter in the HFRR test to around 200 μm at a concentration of 200 mg/kg, putting them well within the maximum allowable limit for market No. 2 diesel fuel. This work suggests that various commercial diesel lubricity additives may be used to improve the durability of high-pressure fuel pumps when used with low-viscosity, light-end fuels
