Comparison of 6.2L Arctic and Standard Fuel Injection Pumps Using JP-8 Fuel.

Abstract

Use of MIL-T-83133 JP-8 aviation turbine fuel (NATO F-34) in compression-ignition engines is being investigated. In previous engine-dynamometer tests, JP-8 was compatible with the 6V-53T and NHC-250 engines but tests with the 6.2L engine indicated that the JP-8 fuel may cause premature fuel injection pump deterioration, resulting in a change in maximum fuel delivery volume and retarding the injection timing. The fuel injection pump manufacturer has experienced premature wear problems with their pumps when operated on low viscosity fuels, such as JP-8 in cold climates and now offers an 'arctic' fuel injection pump designed to operate with lower viscosity fuels. This program sought to determine if that pump is superior to the standard pump in preventing premature wear with JP-8 fuel. Results of 200-hour test indicate that the arctic pump performed better than the standard pump in injection timing change (caused by internal drive tang wear), while the standard pump was better in governor thrust washer wear.
