There you go Zeke!!!!
A second tank.
It also answered my next question.
What do you do when you are running on homebrew that is not anhydrous
simply because you can't achieve 99+%, and you are low on fuel? ex Traveling
and have to fill up with "store-bought" fuel; E-85 or even gasoline.
Answer: Fill the second tank, flip a switch and off you go.
Thanks Zeke,
Tom

Subject: Re: [Biofuel] Ethanol and cold starts
I think I may have misread your questions. It seems you are asking what to
do if you already have the water in there, from homebrew Ethanol?
Hmmmmm..... Perhaps a dual tank setup like we use for SVO in diesels. A block
heater would probably help, but then you are using alot of electricity -- and
is that renewably produced?

I don't think that adding water would be the right way to go. I think the
problem is that ethanol has a higher vapor pressure than gasoline, and in cold
weather, it is hard to get it to vaporize into a fuel-air mixture effectively.
Gasoline vaporizes much easier, and gets the engine going and initiates the
combustion. But water has an even higher vapor pressure than ethanol, plus it
is not a fuel, so I don't think it would help. Since all of the commercially
produced flex fuel vehicals that I've seen are designed to run E85, I think
they just rely on the gasoline content to start in the winter. What bugs me is
that I can't buy any flex fuel vehicals that are efficient -- I mean, if I want
a flex fuel vehical, I have to upgrade to a full sized pickup or a V8 sedan.
Where's the little 4 cylinder efficient flex fuel vehical? Guess it's not all
that hard to change out carbureator jets to change the fuel air ratio yourself
to allow running ethanol.

Hello All,
I've read that people using ethanol, blend in 15 - 20% gasoline to
improve cold weather starts.
What would one do if they were running on 85 - 90% ethanol : 10 -15%
water to improve cold weather starts?
Do flex fuel cars have options for block heaters?
Thanks,
Tom
