So rather than making a fuel/air mixture elsewhere and dragging it past the plugs at 100 MPH and complaining about HC problems, let us inject our burning mixture into the hottest possible compressed air we can make, and do it between the current plug locations. You cannot detonate it when all of the fuel is in one location. And if it cannot detonate how much boost could it stand? High boost with no inter-cooler?
Lynn, I think you are so far above my head that I'm only getting the 10,000ft view of what's going on. I've read your post twice, and still don't know that I have it. But tell me if this sound right.
The Carnot cycle, in its simplest form, we have a chamber that ingest some air, compresses it, heats it, then extracts energy from the resulting expansion. The heating has traditionally been done by mixing some fuel in with the ingested air, and burning it after it is compressed. You're suggesting that we replace the fuel/air mixture with a sort of blowtorch? The mixture comes in burning, and if there are any surplus HCs left over there is plenty of oxygen floating around in the chamber to take care of them while their energy is still useful. Efficiency goes up. Exhaust temps and noise both drop. What would it take, somewhere between 150 and 200 psi on the mixture injectors to handle 8:1 or 9:1 compression ratio rotors?
