New fuel for GA?

for those interested , here is a link to the Swift patent. It sounds
pretty complicated with 5 different components. One of the components
used to lower the vapour pressure is ethyl acetate, a solvent used in
nail polish , varnish etc.
This fuel is going to have quite an interesting odour. The
percentage of the various components can apparently be varied to
adjust octane rating for both aviation and auto use.

For you cehm wonks, here's the nugget:

"... the present inventors provide a renewable fuel comprised of:
(a) one or more low carbon esters derivable from ethanol;
(b) one or more pentosan derivable furans;
(c) one or more aromatic hydrocarbons derived from acetone or propyne;
(d) one or more C4-C io straight chain alkanes derivable from
polysaccharides; and
(e) one or more bio-oils derived from plant germ."

Soup for the needy AvPlane, I say.

Tell me this, what do you make of his claim that you can pour this stuff
straight into an airplane set up for Avgas? No timing or mixture
changes, no hardware changes?

If it really is a substitute for 100LL, then that would be exactly
what one would do.

A pretty big 'if', though. If he can really make the stuff, why is
he talking instead of mixing? If you can put avgas out at 1/2 the price
as he seemed to be claiming, he could get a lot of attention with a
pump pumping for $2.499 / gallon.

Of course, if he makes the stuff without lead, then I don't see why
it wouldn't work in most cars as well. At $2.499 / gallon, he could
sell all he could make.

*IF* he can do it.

Exactly. Even if were the same price and did what he claims ( greater
range for volume) he could still outsell Avgas.

Based on the claims, the only unknown for auto use would be the
oxygenate requirement, i.e. would alcohol have to be added and would
it be compatible.

As for sales, if he could really make the stuff significantly cheaper,
why isn't he doing it now?

The US isn't the only market for fuel in the world.

Timing? probably, if the octane rating is there.

Mixture? You would probably have to adjust mixture accordingly. The
different fuel density would probably require adjustments to float
levels.

Other hardware changes?

I would have to see the materials compatibility tests before I started
using it. It has been known since the 1950s that the synthetic rubber
used in hoses, etc. can tolerate either petroleum-based or
parrafin-based fuels.

The problems arise when switching (either way) between the two, since
each type fuel has its own effect on the polymers.

Well, my luscombe had virtually nothing in the fuel system vunerable to
anything this side of Skydrol, but only because I installed a metal
float and an automotive fuel line. The float seat is metal of course and
there's nothing else in the system that anythign can melt. My KCAB is
anouther thing altogether. The LeBlond I'm going to have to check, but I
think it has a standard MS carb form the thirties anyway, so it should
be fine.
