Where the Wild Things Are
My question was really if you squirt the fuel into the case, can you time a distinct pulse of fuel so it goes up the transfers and into the chamber, such that you could have mostly clean air before it like strato does? Can you keep from blowing fuel out the open exhaust port?Why not? That should be really easy. Just add on a tachometer couple it with the fuel injection and voila finished.

It seems to me that you'd have to have a very short injection pulse - it can't start too early, it would have to be after the transfers open. It can't last too long or not all of it will get up into the chamber, leaving some in the case, and then there will be no clean air for the next next event. And if you don't let any residual into the case, then there will be no lubrication. Basically, I don't think this system can do what strato does. It can control the fuel/air mixture like AT, but at a much higher mechanical complexity. Naturally the Germans would think more complexity was good.....
