Gasoline Vapor System... 150mpg = Unstoppable

While gasoline engines are no doubt a rarity in buses, has anyone experimented with a vapor fuel system? I have dabbled but only with smaller engines, it is for sure viable and worth interest if only for use with gas generators, and possibly ones personal vehicle. I would love to hear your thoughts!

I've played with H-H-O systems on gassers, and CNG fogged into diesels. Both with good results. Never have done the Vapor thing though....

Don't all gasoline engines run off gasoline vapor, even those with fuel injection? Can liquid gasoline (or any liquid fuel) even burn at all? Come to think about it, can anything non-gaseous burn? Just wondering.

Some years ago there was a contributor on this very forum who said that diesel engines could run off water! I also recollect someone else seriously advocating some perpetual-motion codswallop. Like it or not, we and our buses are all subject to the immutable laws of physics.

Engines burn atomized fuel. Its not a vapor- its tiny drops, more a mist.

The proof is in the pudding. I want to believe you but you gotta post some sort of proof. I will not hold you accountable to 150 mpg in a schoolbus because that seems absurd. But if you could provide proof that whatever vehicle you Frankenstein together with a vaporizing gas system, I would love to hear more detail with diagrams, pictures, and build process.

There has been extensive research done on this topic for many years. in fact i looked into it as a teen, excited by ads in the back of Popular science magazines in the 80s. d it has all be proven false. You can get a motor to rev higher with gas vapor but there is not enough energy released to provide any power, under load it fails.

there were 3 guys from Florida in the 90s who mastered the hho system with electrolysis and the perfect resonant frequency to create the combustible gas with minimal electricity from water, but didn't make it to the 21st century...

IDK, but the only guys I can think of were Stan Meyers and his brother. He was convicted of fraud in Ohio court.

every now and then the rumors of the legendary pogue carburetor pop up in the news these have been floating around for all of my 60 years my father actually got copy's of the patent application and i was able to see how it was theorized to work first it was used on a worn out engine (read here not much friction left on the piston rings so not much heat build up) it relied on leaning out the mixture by attempting to vaporize the fuel unfortunately it did cut back its horsepower output this setup would never work if you had a heavy load modern fuel injectors are still the best until we can raise our engine operating temp to extremely high numbers that's why we need ceramic engines

One of the coolest motors I never heard of again was an engine built by Smokey Yanuck, the engine guy for Popular Mechanics way back when. Somewhere around 1960 or so he cut a four cylinder engine down to two...then had pure carbon cylinder sleeves and pistons made for it (Super $$$). Since the carbon could handle many times the heat and does not expand, he pumped it up to something like 250+ horses on regular gas and it got fantastic MPG. After all...an internal combustion motor is simply a heat engine, and the more BTU's...the more ponies. Until it all melts.

You'd think with today's technology, someone could be tapping into that heat.

You can not more out of the fuel then is in it. Diesel are about 35% efficient at best. Carnot gives you the max efficiency for a given cycle.

Elsbett, a german enineer working for MAN and deveoped partially duringthe second worldwar for the luftwaffe. He made some progress by reducing the heat loss thru the piston and thus increasing efficiency. There is no hopla and magic.
Not sure why that motor is not used more at this time. There were some indications that the oil companies tried to by his patents to keep him out of business.
Google the guy, pretty interesting stuff.

When it come a time for independent real world testing
They hucksters always say the oil companies bought the patent.

Yeah, but just take the time to google a little before you attack... wikipedia has some on it as well. The company is still in business.

good luck

I have an old book somewhere on this subject.think it is called"browns alcohol motor fuel cookbook"basically the same concept.basicly by completely vaporizing the gas, you greatly expand your fuel source.its been some time since I have looked at the book, but it seems to me that there would be a drastic loss in power.generally, the cooler you can get your fuel the denser the air fuel mix becomes resulting in more power less mpg.i respect the opposite would be true if you were to heat the fuel.better mpg's less power.the question is...where is the sweet spot? I think the key to max mpg is gona be engine efficiency (and aerodynamics) first.

Supposedly there is a carburetor called the fish carb or the fishman carb that uses vaporization to increase mpg.
