ABSTRACT:
An apparatus and method to automate octane number measurements from a knock engine is provided. A first and second reference fuel having different knock octane numbers and a test fuel having an unknown octane number are each provided to the fuel inlet of an engine at a series of flow rates. For each flow rate an average knock intensity is calculated and from the resulting series of average knock intensities, a flow rate which will give a maximum knock intensity is calculated using curve fitting techniques.
