ABSTRACT:
A method for testing an unleaded aviation gasoline (Avgas) composition involves (a) running an aviation engine such as a Textron Lycoming IO-360 engine with an Avgas at maximum knocking conditions, (b) collecting pressure trace data of continuous engine cycles with pressure transducers attached to the cylinders, (c) filtering and transforming the data, and (d) determining the number of knocking cycles and intensity within a predetermined number of continuous engine cycles.
