You may find this write up of the engine interesting:

www.libralato.co.uk/docs/Libralato_Engine_Technical_Summary.pdf

Unfortunately the description does not include the BSFC or compare the Atkinson cycle, piston engine in the graph. A minor point but I get a little anxious when someone claims "50% efficiency" without providing a traditional BSFC chart.
