FUEL VAPORIZATION, DOUBLES MILEAGE
« on: July 21, 2008, 09:34:18 PM »
Ok, here's what I did.
My brother and I were looking at ways to increase mileage because of the high cost of fuel.

We ran across a you tube vid of a guy running a generator on fuel vapor, by sucking the inducton air through liquid fuel, then to the carb.
We did the same thing, using an 11HP, briggs & stratton, riding lawnmower.  Here's what we did:

Disconnected the fuel line from the carb, and drained the tank, left line off carb.

Removed fuel drain from carb float bowl, draining the fuel, and left the screw out.

Removed air cleaner assembly from carb.

Connected an air hose from the carb to a coffee container lid.

Connected small hoses from the lid down to the bottom of the coffee container.

Filled the container half way with gas, and put the lid on.

Started the motor, which ran perfect.

The total time invested at this point was 15 minutes.  We ran the motor for 15 minutes with a known quantity of gas, at half throttle, then measured how much it burned, then hooked it up normally and ran it again for 15 minutes.

THE ENGINE BURNED TWICE AS MUCH.

We measured exhaust temps, and it tested normal.
This test engine runs very nice on the vapor, probably better than stock.
Our next test will be on a V8 engine, hopefully this week.
I have pics to post, and will try a vid as well, but I'm at work, and all that stuff is at home.

Damn.. Nice trick.. Seems like it would work with any ICE with a carb.. You might not have as much pick-up when your 4 barrel carb tries to dump massive amounts of gas into that v8.. Is it a 350 chevy?

hey Rasta,

We are working on a solution for the acceleraion of the larger engine,  and with our new ideas, we think we got it covered.
The first engine is a 302 ford, with a 4 barrel edelbrock, the second one is a 350 with throttle body injection.
I think the only difference will be tricking the computer, so the engine light won't turn on.

There are reports of a guy in France that is flying his helicopter with a similar system.

We are really excited about this, cause even our first crude attempt burned half the fuel.
This could be the answer to reducing our dependance on big oil.

Thats awesome.. If this works.. We should give every ICE developer a swift kick in the nuts! I mean they got the time and all the engineers.. Hoping this works out for ya.. It has me thinking!

Edit -- if you increase the air flow.. It might take care of that acceleration issue... hmm

Hey Rasta,

Yah, this really seems to work, I can't believe how simple it was.  The engine does run a little bit leaner, however not lean enough to cause any damage.

I agree, the key is to vary the air into the tank, this is something the throttle butterfly does anyways, so it takes the throttle just fine.  I was really suprised that the engine accellerates as good as it does. No stumbling at all.

The key is that the fuel vapor is much easier to ignite, so even though the amount of fuel is greatly reduced, it burns so much easier, performance is as good, or better, than before.

If you have an old lawnmower, or snowblower around, try it.
I can't wait to try it on the trucks.  It's gonna be great.

Howdy Y'all,

This is making me think of the Pogue (sp?) carburetor which vaporized fuel.  It was from back in the 70's.  It utilized a system that heated the gasoline to enhance the vapor production, and only fed the vapors to the engine.  Hot gas is hazardous, so lets try another way.  Ultrasonic transducers placed down in the plenum of the manifold, pointed up towards the carburetor would be effective at vaporizing the fuel in the air mixture as it is exiting the carburetor...

Good luck with your project...

Blessed Be Brothers...

Hi z monkey,

Actually this is alot older than the '70s.

There is actually a patent from the '30s for a carb that was to give 100MPG
It used what looks like a radiator in the float bowl to bubble air through it to produce the vapor.

This has been kept from us for a long time.

It's time to bring it back.

I believe the concept here is just to burn the emitted gas vapors without inducing liquid gas to vaporize right before combustion.

edit-- I wish I got 100 MPG.. damn.. A oil change once every tank and a half.. :)

That's it exactly rasta.  Liquid fuel never comes within 2 feet of the carb with our setup.

actually, Pogue was from back in the 30's or so. The method and guy you are copying is Tom Ogle. check his patent, he's from the 70's.

He heated his gas tank and ran the engine off the fumes. I duplicated this about 30 years ago as a kid on my dad's lawn mower, and i didn't even heat the gas...strictly cold fumes.

fuel vapors burn more fully and easily this is real but hard cause the man keep changing gas formula

hallo dirt diggler,

I am new in here...

sorry for my bad english, but what do mean with "coffee container" and "coffee container lid" ?
can you please make a picture of the engine?

I have also an old Briggs & Stratton engine and will try that  ;D

greetings
felix

Hi everyone.

Here's the pics of what we did.

In the pics you will see that some of the small holes have tubes on them and some don't.  Tis was so that we could tune the mixture by blocking off some of the lines that draw fuel vapor, and allow ones that only draw fresh air in to flow. 
As I said, this is a very simple first attempt, but show increadible promise.

Try this out ;D

ciao,   Dirt
