Another "vaporization myth"
The common belief, and the part that reads well, is that vaporizing a fuel better will get a more even mix with the air so you can use less fuel to get the same power.
And just enough of that is true so people believe the rest, which is the myth part.
First thing you need to know is that gasoline engines run on a 14.7:1 air:fuel mix
14.7 parts air to 1 part fuel
But....you CAN NOT pick what "part" means, 14.7:1`is a WEIGHT ratio, so "part" must be some weight measure, grams, ounces, kilos, pounds, doesn't matter what you decide to use, but it must be by weight.
This is where the "vaporizer" proponent's part from the truth, they use Volume measurements for their explanation, which reads well but just isn't true.
If you have 14.7 grams of air then you need 1 gram of gasoline to get a good burn, doesn't matter how much you separate the gasoline molecules(vaporize) they must add up to 1 gram in weight if there is 14.7 grams of air.
The part that is true is that if you are dripping the gasoline into an engine it won't get a very good mix with the air, so to get the correct 14.7 grams of air mixed with 1 gram of fuel you end up having to add more fuel.
Older carbs did OK but a bit of the fuel would end up coating the inside of the intake.
Fuel injection does better but you still end up with some gas wasted on the back of the intake valve.
Direct injection is probably the best.
