     I think some work was done but fuel vaporization left a lot to be desired
     as I recall. Probably a little intake manifold heat would help
     the BSFC but must be turned off when max power is needed.

Paul, you may not remember this but I mentioned that the Mercury
6 cylinder two stroke outboard injection looked perfect to use on a
rotary! They don't have mixing problems on the 2 strokes due to the
high pressure of the injected mixture atomizing it very well. It seems
like a perfect way to use the rotary combustion chamber like a stratified
charge piston engine combustion chamber. I believe the hydrogen
powered rotary injected by the first spark plug. Less problem with
mixing of course.

I am almost certain Mazda tried all these things. There is a lot of pressure
on them to improve the MPG. Note the intake heat on the RX8.
