Abstract

Motor gasoline is a potential emergency fuel for aircraft using turbine engines. Due to the lack of data on the deposit forming tendencies of motor gasoline, a series of tests was conducted on four samples using the jet fuel thermal oxidation tester. The motor gasoline samples responded to exposure to high temperatures in a manner identical to the response of JP-4 with the exception that the breakpoint temperature was approximately 10 C below the specification limit for JP-4. Filter plugging was not a problem. The effect of contamination of JP-4 with motor gasoline was investigated. The thermal stability of the resulting blend may be lowered to the thermal stability level of the motor gasoline. Hence, the blend may not meet JP-4 specification requirements. (Author)
