This project attempted to determine the fuel lubricity requirements of the Sulzer 12ZAV40S fuel injection system. Wear rates with F-76 and JP-5 fuels were attempted using radioactive tracer technologies using a fuel injection system test stand. Within the sensitivity of the resulting activation, and due to detector instabilities, the wear of fuel injection components could not be quantified using on-line in-situ radioactivity monitoring techniques. Off-line monitoring did indicate wear, but only after a catastrophic wear event. The methods did indicate however that the wear with JP-5 fuel was not significantly different than Diesel Fuel Marine DFM fuel within the scope of the method with the high durability components. Recommendations were made for future testing.
