What has been the discussion so far concerning air assisted direct fuel
injection stratified charge for the Wankel.

It would seem that the wide circumferential depression of the rotor would
allow for optimizing the injection timing and that less loss would occur
from sealing than that of a spark plug with proper tip configuration for the
air-fuel injector nozzle.

This would seem to have the optimize the possibilities of a true stratified
charge with no fuel on the walls of the Wankel to optimize the BSFC.

The injector would possible be of Australian Orbital Tech Group type to be
used in the GM XV-8 Opel Signum 2011.  Now since the German
Government owns Opel this is probably in question.  Have you heard is GM
planning to use the XV-8 in any US car or truck?

To my knowledge3dge nobody has tried that in a rotary.
The Wankel is naturally stratified charge as the rich mixture
is thrown out towards the plugs due to the rotating combustion
chamber. That is probably why it will run a couple of hundred
degrees F lean of peak. Mixture ratios of 20:1 air fuel.
