Abstract : This project attempted to determine the kerosene and Ultra Low Sulfur Diesel fuel lubricity requirements of Delphi DPA rotary fuel injection pumps and Detroit Diesel unit injectors. A test stand was configured to operate a rotary fuel injection pump and a stand configured to operated four unit injectors simultaneously, with data acquisition and control systems for logging data. Results suggest that synthetic kerosene fuel adversely impacts rotary fuel injection pump performance and durability. Synthetic diesel fuel can be blended with petroleum diesel fuel and fuel lubricity additives to provide the same protection as F-76 diesel fuel in rotary fuel injection pumps. The unit injectors are less sensitive to the low lubricity fuels than the rotary fuel injection pumps.
