here is an animated gif from www.der-wankelmotor.de it shows the original of
Wankel's idea on improving a turbin. Check it out, no reciprocating parts.
The spark plugs where in the internal rotating part.
I don't know if the gif animates in your email reader - you might have to
save it to your PC first and then look at it with a web browser.

Thanks, Marko. That's a very interesting engine. The current configuration seems to be even better though it's easy to see Wankel's progression of thought in these engines.

Au contraire, Mon Ami ...
Felix himself said that Mazda "Had made a mule of his race horse", with their re-design to it's current configuration.
If you look closely at that gif, it is in perfect balance at all stages of housing/rotor rotation. No bearing loads due to "wobble".
Prototypes were said to run 40 thousand RPM ! Current Mazda designs are limited to 13K or so due to exceeding rated bearing loads above those speeds
If I reacall, it was not practical insofar as it was similar to the old "Rhone" engines where the crank stood still and the engine rotated around it, and you had to disassemble the engine to change spark plugs, but what the hey, nobody's perfect.
