Using 25 Percent / 75 Percent ATJ/JP-8 Blend Rotary Fuel Injection Pump Wear Testing at Elevated Temperature

Abstract

A 25 percent / 75 percent blend of ATJ/JP-8 fuels at two CI/LI 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 CI/LI 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 CI/LI treatment lasted the 1000-hour duration, but with severe wear and degraded fuel injection pump performance was seen on both pumps.
