Okay, so they are the "stock" GDI injectors, then?

What method of stratified charge are they using?  If
it is a two-stroke and based on the Orbital design, I
believe they are using a spray-guided philosophy,
which would seem to require that you move the pocket
in the head/piston along with the spark plug if you
move the injector...

Where did the system come from that you are using?

Well, combustion pressure is combustion pressure.  I
don't think it matters how many cycles the engine
uses, when you light off the mixture, a peak pressure
is reached.  :D

I guess maybe I'm not understanding what you are
trying to do.  GDI, correct?  Injector within the
limits of the combustion chamber at TDC?  Or within
one of the ports in the cylinder?  Or inside a pocket
in the cylinder head behind a rotary valve?

Heck, I don't think any can be adapted to most
engines.  You have to adapt the engine and they system
around each other, to some degree, by my
understanding.  You can't just modify a GDI system to
work on a particular engine.

I guess if *I* am to be of any real help, I need more
details.  I'm not even sure what it is specifically
that you are asking.
