Years ago, when I was a journalist, I interviewed a guy from the local community who claimed he had invented a carburetor that actually vaporized the fuel. Most carbs just atomize it -- reduce it to very fine droplets. So do fuel injectors. Liquid gasoline won't burn; it must first vaporize (shift states). That is an energy-intensive process, and reduces the amount of energy available for useful work.

A true vapor carburetor would provide far more energy per intake cycle than one that atomized fuel. The inventor claimed that the resulting explosion could not be contained by a gas engine's cylinder head. He was forced to tool a diesel engine head to keep the thing from blowing apart.

I was skeptical (that was back in the days when journalists were.) So I consulted a physics professor at the University of Colorado. He verified (in general terms) the results I had been given.

That sounds a lot like what you're describing.

Exactly, but here's the thing, your using much less fuel for the same flame front of "bang" ( or rapidly expanding fire).

So, you really get the same bang for less bucks.

Not only do you not need stronger heads, but they last longer (no carbon buildup).

That "lasting longer" bit is why we went with cats.( God forbid, who would want that!).
