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.

We are not heating the fuel either, although we are considering it, as there are probably more gains to be had that way as well.

So, you say that you did this 30 years ago, and didn't continue with it?  I don't understand why you wouldn't investigate further on a possible way to half gas consumption.
Give it a try again, maybe this is the future of the ICE.

Thanks for the pics.. Glad to see your still working on this.. I would try it, but do not have any small engines to mess with really..And I would hate to try this on a fuel injected system the first time around..
Please keep us informed.. And hopefully some other people will play around with this as well.. Would love to just get 30% increase on gas mileage on one of my vehicles.

Hey Dirt, if you run into some trouble with that carb or F/I, find a propane carb setup (like from a forklift).  That will have the necessary plumbing to feed a bigger engine.  You may have to open the jets up some, but it should work.  Also will work when u want to heat the fuel. I think the best is to use ethanol, you would only have to heat it to 173 deg. F and inject the vaporized fuel using the propane style carb.  PLus the ethanol is pure without additives, not to mention might actually be cheaper then gas!  Then crank up the compression ratio!!!!  18 to 1 is best.

Hi Mark,

The way this works is that we don't use any jets.  The carb could be completely removed, the only thing required is the butterfly.  In fact that may be exactly what happens on the V8 we are working on.  A simple flaper to retrict air flow is all that is needed.
Because the fuel vapor is already mixed with the air before the carb, none of the fuel metering is needed, only a way to change air flow to the engine.

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.
Was the engine under load at half throttle when you did the test or was it freewheeling?
Good job ;D

Hi Allcanadian

The first test was done no load, fixed throttle.  The next test, as soon as possible will be to go and actually cut the grass with it to confirm operation.

Will post results as soon as tests are completed.

Dirt tried it Geet 2 yrs ago on small gas motor [panasea has step by step instructions]want to try on old diesel   a lot in France with this    PESE posted on the geet small engine thread very recently much info   Sailing only once this year big boat is out for a refit let yah know when its back in the water   Chet

Looks like heating the fuel is something that's already been tried, and works:

Just to name a few.

dirtdggler, this is looking very neat, look forward to seeing development on the v8.
what with Archer's wheel, and your coffee can it could be a busy summer.
many thanks for all the info:

regards, bren.

Thanks guys,

This kind of stuff is real fun to try, we are having a good time ;D ;D

Got most of the V8 system figured out, won't be as crude as the coffee can ;)

The full load test on the lawn tractor should with any luck, happen tonight.

Will post results.

I have some scripts about a guy from the 70ies
with very detailed vaporizer descriptions.
Have to look - cannot find them on the net anymore.
He had a huge disclaimer on what you should do
and - what is almost very dangerous.

Hey Fritz,
I have a feeling that what your talking about being dangerous is the possibility of backfiring.  With the design we have in mind there shouldn't be any problems with the vapour igniting and proceeding back to our fuel supply.

No problem there - more problem with sealing, corrosion and the hazards you can get if some fuel clouds around you ignite.
Be careful.

me from now on - whenever I look in the mirror;-))))
