Lubricity of JP-5 and Diesel Fuels.
Abstract
The U.S. Army is considering the replacement of diesel fuels by aviation turbine fuels, and is pursuing development of a universal middle distillate fuel in which certain lubricity parameters are needed. The wear and friction characteristics of eleven selected aviation turbine and diesel fuels were evaluated with the aid of the Exxon Research and Engineering Company's Ball-On-Cylinder-Machine. Limited additional testing of some of the fuels was done with the aid of the Vicker Vane Pump. Fuel nitrogen and sulfur levels, as well as back end volatilities and viscosities, are factors in wear phenomena. Relative humidity of the ambient air, or water content of the fuels, has a significant effect upon the fuels' lubricity properties. Wear phenomena observed with the Ball-On-Cylinder-Machine and the Vicker Vane Pump are correlatable.
