The objective of this investigation was to identify and document potential performance, maintenance and cost impacts on diesel engine operation when using JP-5. Based on the data and information gathered during this investigation and detailed in this report, the adoption of JP-5 as the single naval fuel at-sea could be accomplished with no major impacts on Naval diesel engines. There are some potential issues regarding the use of JP-5 in a small number of engines. However, for the majority of Naval diesel engines the transition should be transparent. It is recommended that a minimum requirement for cetane number and lubricity potentially be incorporated into the JP-5 specification to insurecompatibility with current and future technology diesel engines. As new engines are introduced, they will incorporate new technologies such as high-pressure common rail fuel injection. These engines are being designed to produce lower exhaust emissions and could possibly have new fuel requirements (highercetane number) . Also, new ship designs, such as LCS, may require engines to be operated at more severe duty cycles and spend more time at full power than is the current practice. The effects of JP-5 fuel properties (lubricity, cetane number, ignition delay, etc.) on these advanced technology engines need to be investigated.
