This is an unusual engine, suggested to Elmer by Richard Castagnola, of Santa Barbara, California. It is a compound using only one cylinder. The valve design feeds the exhaust from the high pressure side to the low pressure side.

The engine in the two videos on this page were built by BhorTjoern Gude Weber.
