Abstract:

A series of tests were conducted to evaluate the impact of a slow-release lubricity dosing filter for equipment protection and storage stability. The hardware system used for testing was a high-pressure common rail system found on John Deere 4.5L Powertech Engines. The completion of a modified test protocol based on the NATO test cycle was set as the passing criterion at 60 oC, 82.8 oC, and 93.3 oC. These results were compared to the results from WD 04 Task XIX at similar temperatures, where in the fuels were treated in bulk with DCI-4A. Based on this criterion, the dosing filter was effective in improving the performance of Jet A at 82.8 oC, and 93.3 oC. It was ineffective in improving the performance for SPK at any temperature. The performance of the dosing filter was comparable to direct DCI-4A treatment for 5050 Jet ASPK fuel blend. HRD fuel passed the test cycle without the lubricity additive doser at all test temperatures.
