HEAVY EQUIPMENT OPERATORS' EVALUATION: JP-5 VERSUS DF-2.
Abstract
The results of previous tests have shown that JP-5 aviation turbine fuel is a suitable substitute for DF-2 diesel fuel in the diesel engines powering the equipment of the Naval Construction Forces. However, several conflicting opinions were expressed concerning the alleged variation in performance which might be detected by heavy equipment operators while using the substitute fuel. Therefore, it was decided to conduct a series of tests to determine whether or not experienced operators could discern a difference in performance between equipment fueled with JP-5 and the same equipment fueled with DF-2. The results of this experiment indicated that well-trained operators could sometimes detect a very slight power loss with JP-5, but that otherwise engine operation is completely normal and adequate. This slight power loss is primarily due to increased leakage of the less viscous JP-5 around the fuel injection plungers. The loss does not appear to be of sufficient magnitude to warrant any change in injector rack settings. (Author)
