To understand critical fuel related impacts, performance and endurance testing was conducted using a fired engine equipped with a modern fuel lubricated HPCR fuel system with a 5050 volumetric blend of JP-8 and hydroprocessed renewable jet HRJ, also known as hydroprocessed esters and fatty acids HEFA, treated with 9ppm of a QPL-25017 additive. Testing was completed using a Ford 6.7L V8 turbocharged diesel engine. Testing was completed following a double-duration modified version of the U.S. Army 210-hour tactical wheeled vehicle cycle TWVC. The engine with JP-8HRJ fuel was successfully operated over the test duration without experiencing any unusual fuel related operational conditions or hardware failures. Post-test fuel injection system inspection found tested components to be in similar condition for all fuels tested. Results from testing support the compatibility of the fuel lubricated HPCR fuel system utilized on the Ford 6.7L with a military specified JP-8HRJ fuel blend.
