ABSTRACT:
First and second reference fuels having different known octane numbers and a test fuel having an unknown octane number are each provided individually to the fuel inlet of an engine at a desired flow rate. The sample valve is utilized to inject test fuel into a fuel flowing to the fuel inlet of the engine so as to be able to determine the octane number of a test fuel based on only a small sample.
