Evaluation of Military Fuels Using a Ford 6.7L Powerstroke Diesel Engine

Abstract

A Ford 6.7L diesel engine utilizing a fuel lubricated high pressure common rail (HPCR) fuel system was evaluated using ULSD, JP-8, 50/50 synthetic paraffinic kerosene (SPK), and 100% SPK to determine the compatibility of modern HPCR fuel systems with military fuels. The engine was operated following the 210hr U.S. Army Tactical Wheeled Vehicle Engine Endurance Cycle (TWVC) to determine fuel system endurance and performance degradation associated with each tested fuel. Pre and post-test powercurves and emissions were completed to monitor and record engine performance, and to determine any power degradation present across the test duration. New fuel system components were installed on the engine prior to each test. After completion, fuel system components were removed and disassembled to determine internal wear present in the high pressure pump and fuel injector assemblies. All components were compared to each other as well as a new unused set of hardware to determine the wear associated with each tested fuels use.
