Not as I recall. I Think Bruce Crower invented the six stroke  engine.
 Half gasoline and half steam.

 And the neat part of it was that no cooling system was
 needed.  Producing the steam on the 5th and 6th parts of the cycle
 cooled the engine!

Hi  Paul,  That little bit about harnessing the heat via steam and the
excess heat in a rotary, could not some clever engineer make a extra
sided rotary and inject water after the exhaust phase and recover plus
cool down the housing and rotor, just before the the next intake phase.
I cannot quite get my head around the shape required, but I think that
may be where the rotary could have the edge, (no valves head gaskets
ect.), just a thought.

You will have to carry distilled water which cost more than
gasoline :)

All of these variations work. Pick one you would like
to use.
