Abstract : As part of the Military Single Fuel Forward Logistics concept, all fuel consuming equipment should be able to operate using JP-8. For most engine driven equipment, this necessitates the use of diesel (compression ignition) rather than gasoline (spark ignition) engines. Because of the lower power density of diesel engines, especially small engines, some current fielded equipment, as well as new equipment being developed, are not complying with the Single Fuel Forward directives. The intent of this study was to survey existing state of the art heavy fuel (diesel) engine technology and recommend an approach to DoD for the acquisition of JP-8 capable engines for these applications. Equipment developers and item managers were surveyed to identity vehicles and equipment currently using gasoline engines, or situation in which engine limitations severely compromise developmental objectives. The characteristics of current state of the art diesel engine technology, along with what might be achievable for military applications, were then compared with these requirements to determine what engine approaches might satisfy the equipment needs. The final recommendation combines the following three steps to satisfy the requirements of the wide range of DoD engine applications: 1) Modify existing diesel engines to meet weight and power specifications to provide 10,000 DoD engines per year; 2 Design a new engine family utilizing commercial technology for most components to provide 33,000 DoD engines per year; 3) Design an engine family of very high power density to provide 1,000 engines per year that can not be produced by the other two steps.
