To support the need to upgrade aviation turbine fuel JP-8 from 'emergency' to 'alternate' status for diesel-powered equipment and to further advance its use as a single-fuel concept, four Army diesel engines were evaluated by dynamometer tests in cyclic endurance test procedures using JP-8 fuel and compared to baseline performance using diesel fuel (DF-2). Results showed the advantages for JP-8 fuel to include: Increased engine efficiency at the maximum power conditions, Lower rate of cylinder combustion chamber deposit formation, Less contamination of the engine lubricant, Less wear of the upper ring area, Lower rate of depletion of the lubricant additives, Less corrosive wear of the engine bearings, and Fewer deposits on the fuel injectors. JP-8 was found to be satisfactory for use in all engines tested. Abnormal wear occurred in the fuel injection pump of the GM 6.2L engine while operating on JP-8 during an engine dynamometer test. This wear resulted in higher fuel-delivery rates and erratic injection timing. Later field tests did not show such wear problems. the use of JP-8 in the diesel-engine powered vehicles holds some advantages, notably for the engine and oil durability for most engines tested. The disadvantages include reduced vehicle range and reduced maximum power.
