I did a little more work on the 3D's with a paint program. I think
this is a solution to the slightly worse fuel consumption. It should
make the rotary equal to the piston engine on fuel burn, In a way
this simulates the piston engine in the way it compresses the
incoming charge.

Paul,
Is anyone currently modifying a rotor to try it out in practice to
derive some actual figures?  I would assume that even a small rotary
could be tried and should indicate if it is worth doing on a Mazda one.

I hope so. I sent it to the guys at Vienna university doing Wankel research for Austro Engines/Diamond Aircraft
but have not heard back. Also AIXRO and Mazda engineering in Japan.

Rather than applying for a patent.

BTW it also reduces the heat transfer to the rotor bearing which is a good thing.
