Caterpillar C7 and GEP 6.5L (T) Fuel System Durability Using 25% ATJ Fuel Blend

Abstract

The U.S. Army has a desire to reduce its dependence on traditional petroleum based fuels. This report covers investigation into the use of an ATJ blended fuel in the Caterpillar C7 and General Engine Products 6.5L(T) diesel engines. With the technical issues presented in this report related to the CAT C7 evaluation and the desert operating condition GEP 6.5L(T) evaluations, a full analysis of the compatibility of the 25% ATJ blend is not possible. In general, the pre-test data acquired with the C7 engine suggests that the engine is compatible with the ATJ blend in regards to engine performance. Fuel system durability was not able to be assessed. For the GEP 6.5L(T) engine, good compatibility was observed with the 25% ATJ at ambient temperatures. Engine power remained consistent across the 210hr durability testing, and pre and post test engine performance and fuel system calibration data showed minimal changes in condition.
