I'm not saying you're wrong, but I'd like to know what you're basing these assertions on.

Based on?

How long is needed?
How quickly does a micro-droplet of a volatile hydrocarbon take to vaporize when it's suspended in a 3000° kelvin gas?
EDIT: I just looked up the auto-ignition point of gasoline - it's 280°C, or 536°F.

What's interesting to me is that diesel engines burn their fuel by compressing it until it explodes - 100% ignition, instantaneously.
Diesel has around 15%(?) more energy content per volume of fuel.
At work, we have a Rav4 gasoline, and a Rav4 diesel, both with similar engine sizes. The diesel gets around 15% better fuel economy.
If the diesel is getting around 35mpg, should not the gasoline version get only 10mpg? What am I missing?

Mazda's direct injection engines have been torn down north of 200,000 miles, and the valves have still been essentially clean. Evidently it depends on the implementation.

Based on? What manufacturers publish suggests incomplete combustion is 2% or less. Are we being lied to?
I'm not suggesting there isn't gain to be had by improving vaporization, but we have the engine makers saying <2%, and you saying 70%. And, we have examples of engines that do not have vaporization problems which show only marginal improvement.
