You need to use IE and install an activex control to view this:

The blue indicates the cold side, the blue port is the fresh air intake. The red is the hot side, the red port is the exhaust port. The small hole is the port that passes in front of the stationary fuel injector and spark plug.
The dilemma I'm having now has to do with port placement. Because the housing also rotates (or can be called the outer rotor), the ports pass along a circular path. My intake and injector ports are on the same path.
My initial thought was to make the side wall extra thick and angle the ports in different directions so when they open on the other side, they are on different paths. But that is just a waste of metal and makes it more complicated because the port injector plane will be inside the fresh air plane. The #1 reason I'm not putting the spark plugs in the inner rotor is to avoid the same problem that Felix had when he first built the DKM: mechanics would have to disassemble the engine just to change them.
So my final thought is I'm just going to have to move that intake port. If I put it along the outer rim, I can create a "scoop". At 10,000rpm+ speeds, I might be able to do away with the extra compressor I was going to use, and let the scoop compress air into the chamber. This is going to interfere with my initial idea of using heatsink fins along the outside to air cool the engine. Although it might still work since only one side of the engine gets hot - I just don't want to be scooping in hot air, so the flow needs to be adequate...

For those of you that don't want to install an ocx, I'm having a few videos made up:

You'll have to adjust your settings to accomodate. We're still trying to figure out how to setup a java version.
