Running of Vapor

It is an often a misconception that most vehicles burn gasoline vapors in their internal combustion engines. The fact of the matter is, gasoline powered vehicles burn finely divided particles or droplets that are sprayed from the carburetor or fuel injectors, into the engine cylinders. This is a very wasteful process of converting gasoline or diesel to energy. Maybe 20-30 % efficiency at most. It has been known and demonstrated for 60 or more years that burning gasoline vapors will give easily 5 times the mpg and near zero emissions. Actually if the vapors are heated to the necessary temperature of 450 degrees F, the gasoline vapors are actually fractionalized by catalytic cracking and converted to smaller light molecular hydrocarbons, methane and methanol.
Running of Vapor
the gasolines in use during the days of the mixing valve were far more volatile than the ones in use today. Some of you may remember when you could stand ten feet away from an open pan of gasoline, light a match, and watch the gasoline immediately catch fire. Gasolines were changed in the 1930s with the advent of the catalytic cracker now used in petroleum refining. Carburetors like the Pogue, which depend on easily vaporized gasoline, simply will not work with today's gasolines. The second seminar-taught error is the method of using exhaust heat or radiator water to heat the fuel to the "vapor" point to extend the mileage. Warming or preheating fuel does have some value, but it's limited. Consider using hot water from the radiator to vaporize the fuel first. Today's gasolines do not completely vaporize until they reach 450º Fahrenheit heat, while the maximum temperature of the water in today's pressure radiators reaches only 250º Fahrenheit. You just can't heat a substance to 450º Fahrenheit using a 250º Fahrenheit heat source.
The 100 MPG Carburetor Myth

450 degrees Fahrenheit = 232.222222 degrees Celsius
250 degrees Fahrenheit = 121.111111 degrees Celsius

But what we can do is heat the entire gas tank up to 120 degrees, it will then depend on the size of the tank how much gas is generated.

Using the exhaust to heat up the inlet will decrease the volume of gasoline consumed thus decrease the heat production allowing the fuel to flow again. It won't explode until it's about 280 degrees so say we inject it at 240. Electronics are our friend.

Then we need some peristaltic configuration to heat the fuel under vacuum, then after it's evaporated it needs to be compressed before it's injected.

You can put a lot of little fuel savers like that in parallel as soon as the engine doesn't get hot enough it automagically starts drinking more liquid fuel.

This idea is just a mind toy of course. You are suppose to finish it. All I have is the riddle.
