It is essentially the same as a 1930's Junkers Jumo 2 stroke
diesel with the  same 2 stroke port timing problems. Therein lie
the problems.

Jeff Spitzer, chief engineer at GA Aircraft Division SD, built a scaled
down copy about ten years ago and had it at OSH. It was rejected by the
AF in favor of a turbo Rotax 914. Even the Germans gave up on it
around 1940.

Here are some Jumo pictures. Also a much smaller version called
the Gemini I saw at Aero in Friedrichshaven in 2009.

Napier built a large 3 crankshaft version called the Deltic. Widely
used in locomotives and boats.

Bill Gates should have checked with me :)

Supertec in Germany are building a high compression diesel version of
the Wankel. A turbo compound of that engine would be unbeatable.
