Thoughts on vaporizing gasoline?
 

I've been reading up on it and watching some videos. Just curious as to some opinions on it. Anyone done anything like that on here?

Ecomodder George Wiseman has- got 400 mpg with a V8 pickup. But he took a sabbatical from his sabbatical before providing us with his online books for free and/or explaining to us how he did it. :/

And there was another guy years ago... said something about blowing up a dump truck with his system. Sorry I don't recall his name or any other details.

You could probably do it on a carbureted vehicle. That'd be a no go with efi unless you built your own purpose-built system. I would love to see a fuel heater for EFI, wouldn't take much to do that.

I think someone here on ecomodder did this. I'm not 100% sure but I know they did something with routing the fuel line right next to something that gets extremely hot (exhaust manifold?). I can't remember if gains were to be had by it, but I know I read it somewhere.

Fuel heaters have been tested and dont show any improvements on modern engines. Turns out they are pretty good at mixing air and fuel.
Plus if fuel vaporizers work so well, you could test it by using a fuel that is superheated at room temperature, like say propane.
Propane is absolutely 100% vaporized at room temperature at atmospheric pressure and offer no fuel economy improvement.

Most don't do the engine mods too make the best of lpg. Or retune the modern engine.:rolleyes:

Your carb/EFI vaporizes gasoline just fine on its own.

Transonic cumbustion super critical fuel injection, multi fuel and blends capable. Compression ignition after initital start.

vaporizing
 

If you'll search the classified ads in the back of a Popular Science Magazine you may still find a listing for Lindsey Publications' paperback '200-MPG Carburetors'.
There are a dozen designs or patent images for the 200 mpg vapor carbs.
The jist of the technology is that you push a car up to 35-mph,start the engine and engage the transmission,then motor along at 35-mph to achieve '200 mpg.'
There is no acceleration,or deceleration,different speeds available,hill-climbing,etc.,just flat level,constant-35-mph travel.:o

If the engine wasnt retuned the vehicle would fail emissions horribly.

200 MPG Carburetor
 

I read a second-hand story about someone who made a vaporizing carburetor as designed by Charles Nelson Pogue (The original "200 MPG carburetor) and installed it on his Ford Mustang. The car ran at a significantly reduced power level, and got 30 MPG.
I prefer to have full power available when I put the spurs to my "pony", but I wouldn't mind 30 MPG. Oh, wait, uh .... :D

If the gasoline hasn't completely vaporized by the time of ignition, The combustion temperature will most likely vaporize what un-vaporized gasoline is left in the mixture.

An automotive engineer with an interest in fuel saving said:

Fuel saving gadgets - a professional engineer's view

That is what other experiments I have read about were saying too.
All were claiming 3% or less.

Which is about what direct injected gasoline engines generally gain? Maybe they are on to something:eek:

35mpg + a 3% improvement is 36.05mpg or 1.05 mpg savings
maybe on a 48mpg car it would be better - that comes to 49.44 mpg or a 1.44mpg savings.

Crunching the numbers also reveals that a 12 gallon 35mpg car you would drive a extra 12.6 miles & a 48mpg car you would drive 17.28 miles further down the road.

It is certainly not novice experimenter friendly. Its more like a novice experimenter exterminator or skin modifier..
