Abstract:

A 25 percent 75 percent blend of ATJJP-8 fuels at two CILI additive concentrations were operated in rotary, mechanical, fuel-lubricated, fuel injection pumps for a 1000-hour target at 77 degrees Celsius fuel inlet temperature. The test with the 9-ppm CILI treatment failed early with a head and rotor seizure on one pump and wear and performance degradation on the other. The test with the 24-ppm CILI treatment lasted the 1000-hour duration, but with severe wear and degraded fuel injection pump performance was seen on both pumps.
