Caterpillar C7 Fuel System Baseline Durability Using F-24 Fuel
Abstract
The U.S. Army has a desire to reduce its dependence on traditional petroleum based fuels. Recent investigation has focused on the viability of alcohol to jet (ATJ) based fuels as a blending component for use with traditional petroleum based aviation fuels. This report covers the establishment of a baseline performance envelope using F-24 in the Caterpillar (CAT) C7 engine. Testing was conducted to allow for comparison to the same envelope developed for the F-24 and ATJ fuel blend that was performed in WD 012. The testing followed an accelerated 210-hour Tactical Wheeled Vehicle (TWV) cycle to determine engine performance, combustion, fuel system durability, raw gas emissions, and combustion related deposits. Overall performance degradation over the 210 hour test duration was approximately 2.5 percent for the F-24 post-test power curves. End of test power levels and emissions are included in this report, as well as post-test inspection of the fuel injector tips, combustion chambers, and fire deck. Performance deviations were seen due to lubricant degradation and not attributed to F-24 fuel.
