Well, maybe if some of the already vaporized fuel could replace in volume some of the air flow, possibly it could act like said enrichment to prevent a knock, but most likely it would decrease performance too.

Well in my cases I am talking about Fuel Injection cars. They run dry intakes and the fuel is added at the intake valve.
None the less atomized fuel do not vaporize in any intake, 190/220 is not hot enough to cause any real vaporizing. Carburetors do not make any vapor any more than does fuel injectors, all they do is spray gasoline droplets which according to knowledge only about 30% vaporize within the combustion chamber.
If gasoline is converted to 100% vapor before fed into the engine reports claim only 30% will be needed for total combustion with no wasted fuel still burning in the exhaust stroke.
Your right about how to control the amount of vapor fed to the engine is one problem to be solved.
All of the claims will need to be tested and proven.
