Hello All,
Steve, good explination about the third spark plug.  Ken at StarApex has
suggested a high pressure line from the other rotor, using combustion
pressure to provide already burned gas to the leading edge to eliminate
the unburned fuel problem.  Seems like a good idea - will this work?
May cost a little power but should lower BSCF and some of the waste
heat.  :D

The first thing Ken  needs to do is get StarApex working with the high
leaning
angle. That is probably the reason Felix did not choose that
configuration.

Feeding back heat and fire from leading chamber was proposed on here
years ago.
I can look it up. Perhaps Ken read about it on here :)

The trouble with it is the fire goes out because passing it back
through a tube cools it too much or no O2 I suspect. One might get
around that
by injecting fresh air and a bit more fuel.

Hi Dan;
I think Ken should present his own ideas, I believe I saw him on this
list previously.
A lot of Ken's ideas have been previously published elsewhere.

If you are thinking of fresh air injection, the better place to inject
it is probably after the
exhaust port close.  This will help replace some of the burned exhaust
gases carrying
over into the intake charge due to to intake-exhaust overlap.
This would also stabilize idle/low-power operation and enable later
exhaust port closing
for better WOT operation.
It might be worth an experiment on a car with a convenient air pump.
Cheers
Cary
