Lubricity of Jet A-1 and JP-4 Fuels
Abstract
This report describes the evaluation of an instrument that gives an indication of the lubricity of a fuel and of the results from testing Jet A-1 and JP-4 fuels with the device. The instrument is the Furey Ball-on-Cylinder. The preliminary investigation dealt with establishing the repeatability and reproducibility of the rig on pure hydrocarbons and Jet A-1 fuels. Also, the results from the Jet A-1 fuels served as the basis for a direct comparison between the wear scar diameter from the Ball-on-Cylinder and the coefficient of friction from the Bendix-CRC Lubricity Simulator. The Jet A-1 fuels which were composed of a high percentage of heavy end hydrocarbons had the best lubricity. In a similar manner, JP-4 fuels which contained corrosion inhibitors, were tested on the Ball-on-Cylinder and the wear scar diameters obtained were compared to the fuels properties. No correlations were found.
