    摘要: The addition of biodiesel to petroleum-based kerosene jet fuels in very low concentrations can lower the temperature at which crystals appear in the fuel. The fuels can comprise a blend of a hydrocarbon base fuel component and, for example, up to 1000 ppm, v/v of the total fuel, of a biodiesel component comprising a lower alkyl ester of a fatty acid of natural origin having from 8 to 24 carbon atoms; these blends can be characterized by improved low temperature flow properties, especially of Cloud Point (ASTM D 2500), which can be lower than that of the petroleum fuel component without the alkyl ester, even in the presence of dissolved water up to the saturation level.

    摘要: Methods are provided for characterizing an aviation gasoline for use in a spark-ignited engine based on analysis methods traditionally used for compression-ignition fuels. For example, an aviation gasoline can be characterized based on a combustion delay for the aviation gasoline, a heat release rate for the aviation gasoline, or a combination thereof. Analyzing an aviation gasoline based on characteristics traditionally used for compression-ignition fuels can allow for distinction between types of aviation gasolines that may appear to be similar under conventional octane tests but that have substantially different performance characteristics.
