Richard,
How difficult would it be to put together an RX8(2 chamber) using your
system with an aluminum center section.
With glow plugs to run on Jet A? Direct injection in each chamber in one
spark plug hole? Your guess on Wt? HP?
Light Wt. rotors, your front, and rear plates, Mazdrax aluminum center
section if necessary, etc. Max life 500 hours. We need your Email address.

If you really want to run on Jet A by using a spark plug and direct
injection would
not a high boost from a turbo ( or super charger ) get the effective
compression
ratio high enough for compression ignition? It would then be nescessary
to start on
gas (gasoline or LPG) and switch over to diesel operation.

Hi, there is a diesel technique called Hyperbar that is used in the
French Leclerc Tank. http://en.wikipedia.org/wiki/AMX-56_Leclerc ;
http://www.competitiondiesel.com/forums/showthread.php?t=107297 It has a
V-8 with 8:1 compression. There is a bypass from the intake manifold to
the exhaust which has a combustion chamber with its own fuel injector and
igniter before the turbine of the "turbocharger". The turbo is actually a
turbo compressor that is started first before the piston engine. It can
free run without the piston engine turning. It may be used as an APU also.
It will supply enough high pressure air so that the piston engine will
start even at the low compression ratio. As the piston engine's out put
increases the fuel to the TC combustion chamber is reduced until it is
running as a turbocharger; for even higher output additional fuel can be
burned for high boost operation.
Can something similar work in a Wankel?
Heavy fuel direct injection takes time for mixture formation and ignition
whether diesel or spark ignition and the rotary works best for aircraft use
as a high rpm machine. I think pre-vaporizing the heavy fuel before the
engine like with port injection of gasoline could work. Heavy fuel has low
octane and that could be a problem with high output but less of a problem
than it would be in piston engines that try the same idea.
The new very high pressure common rail diesel injection systems with
multiple injections per cycle might work at rotary speeds. A mechanically
driven supercharger as mentioned could work also.

If somebody wants to read the history of this subject I highly recommend downloading
these papers.

One of the appendixes #17 discusses the turbo compounds aspects.
