I'd be more interested to hear if anyone has tried:
Acetone as a fuel additive? Or
Flame front channels cut into the rotor face?
Dimpled intake/rotor faces?

Yes but this is for piston engines. Not necessarily
will it work for the rotary.

Seems since the piston engine is bass ackwards compared to the rotary
engine
we need to figure out a way to conduct the spark to the fuel. Inlaid
matrix
pattern of ceramic semi conductors to create a plasma? It works on our
corona discharge ozone generators but that environment is not so hot.
Ozone won't happen over about 40C. Plasmas will and some ozone
generators
work better under several atmospheres. Good match?
It is interesting to note that the outer part of the ozone generator is
stainless steel and the inner dielectric is a ceramic semi conductor.
Our early designs used nickel power inside a glass tube and with an air
gap
of about 3mm. We drove them with Toyota ignition coils and on 24vdc.
Some coatings of titanium work great in plasma generators. Coat the
correct
area of the rotor depression, and mix in some platinum as well while you
at
it:) Have the apex seal or a conductive corner seal hit a curved contact
in
the side housing to fire the circuit. The circuit can be advanced or
retarded electronically.
This information is now officially in public domain:)

A rarely mentioned fact is the combustion chamber and combustion process
are
rotating while the spark plugs are fixed.

Didn't the John Deere Wankle use plasma ignition ?

Do you have an SAE paper reference on that?
Paul Lamar ...No rotor no motor.
What's the possibilities of stamping rotors with almost any combustions
shape you desire? Lighter, cooler running, etc.. Now finishing them and
sealing them; as well as attaching gears might be something to bring on more
thought process. Could do like automatic and spline, somehow attach, the
stamped rotor to geared center. Of course, that's what all you smart fellers
are for?

Exactly, my point, about the rotating combustion chamber and gases which is
why the spark or plasma should be rotating along with it. The stainless
rotor housing is already negatively grounded. Within the rotor there would
need to be three small wires carrying the plus current from the corner seal
into the appropriate area on the rotor face. The carbon iron corner seal
could ride in an electrically insulated material and contact the
tangentially arched conductor imbedded within an insulator on the cool side
of the side housing. Exact location and length of the linear conductor
depends on the desired combustion event and ultimately depends on the
position of the rotor face angle. The nice thing about plasma is you can
move it around and change the intensity.
The bad thing about it is it gap, moisture and pressure sensitive and
depending on the duration of the pulse wave form it may have to be stepped
up in power. Not a insurmountable problem with the fast switching FETs now
on the market.
IMHO the biggest challenge would be to create durable coatings on the rotor
face. There would need to be a non conducting coating followed by the a
conducting layer with microscopic peaks and valleys, and finished with a
glass like coating to seal it. If there is to much moisture in the chamber
some of the high tech ceramic plasma generators get permanently ruined and
refuse to fire.
This is a challenge for our materials engineers on this list. Spark plugs
are definitely easier to change than rotors though:)
Maybe I should stick with muffler bearings and I'm sure that I'd make a
better living selling them but lighting off a mixture using a spark plug in
this day and age? Perhaps one pointedness is best reserved for thought
processes.
