I've never had a chance to destroy a fancy high-volume propane regulator,
but earlier this summer I was fooling around with this very simple RV
appliance type that I really liked. It was just a diaphram that closed as
a function of the output pressure. The input went directly to the tank but
there semmed to be no mechanical policy requiring a liquid source to
function as long as the connection from the tank to the input of the
regulator was not forcefully heated. Since then I've been curious as to
why the input side shouldn't flow through a passive radiator/blower and be
used to recover the phase change cooling before going to a regulator? With
a water heated type of regulator fed by the high pressure side of
liquified fuel into an inadequate exchanger I would think it should get
very cold - enough for an air conditioner without necessarily having to
even function, like in the winter, for the fuel to simply flow through an
iced block of 'let the water exchanger work full time when necessary'. If
that makes sense. The last article I read
http://www.motherearthnews.com/libra...Car_To_Propane
about propane conversioning used 'demand' regulator (I don't know what, if
any, difference that is from the simple RV regulator) to a jet drilled and
tapped into the throat of a carburator. I did see something about these
vaccuum adjustable diaphrams in some regulators for forklifts, etc.
What kind of regulator does it take to supply a large engine - I assume
the delivery capacity is more a function of keeping it from freezing than
any limitations of the orifices in the regulator casting as it is
essentially a fuel line but I couldn't figure out what kind of jet this
guy was using in the carburetor body. I would think that since it is
supplying vapor from that point then you would need something
substantially larger than a carb jet but I can't get past the idea of
venting that much vapor during engine startup as what the engine would
need while running. Maybe that's what this 'spud-jet' he was using is -
some kind of normally closed but on/off ball & spring type deal like a
backwards PCV valve sort of thing.

Most of what I can find now about propane conversions are very expensive
'kits', you can't even seem to find one that isn't application specific
(make/model/year). I suppose due to all the fuel-injected vehicles with
engine management and the legal issues of supplying carburator based
solutions while still being able to advertise a solution for vehicles made
during the last 20 years. If anybody has any links to pre-engineered
universal type conversions I'd like to look them over.

Like this:
tank --> inefficient finned radiator style excanger --> water
heated regulator ---> carburetor.

I say 'inefficient' because of the complications of having it completely
replace the function of the water heated regulator but enough to provide
some cooling effect. I don't really want to be the guniea pig though. :)

Ah hell, I guess the damned tank pressure will prevent the fuel from doing
any kind of pre-reg vaporising. That's too bad, it's gets awful hot
crawling around at 5mph through the woods.
