Since 1965, diesel engine endurance tests have been conducted in a variety of compression-ignition engines using JP-5 or 'JP-8 as the fuel and comp Iaring performances with DP-2. None 'of these tests showed engine failures or excessive wear attributable to the use of kerosene-type aircraft turbine fuels, although slightly reduced fuel injection delivery volumes and lower 'power output were experienced in most engines, due to lower viscosity and lower heat content of JP-5 and JP-8 compared to DF-2.' These results not withstanding. % periodically, concerns are r~aised about the use of JP-5 and JP-8 in diesel engines over -long periods in the 500-to 1000-hour time frame, especially in new engine designs. This report Is primarily an annotated bibliography of 23 references consisting of. technical notes.' letcers, letter reports, and Interim reports, on the subject of using aircraft turblike fuels JP-S and JP- TRBE-VF__
