Alcohol for fuel
- My interests are in using alcohol for fuel. I'm seeing this kind of
advice in some newsgroup postings:
? Do not use gasohal or gasoline alcohol fuel blends.
My briggs and straton manual says the same thing, and so do other
places, but why? Why can't I use alcohol in the generator? I'm
aware that alcohol mixed with gas will burn more completely (possibly
burn hotter) but my understanding is that alcohol when burned by
itself burns substantially cooler (thus nascar uses it).
I'd like to build a small 12 vdc generator out of a gmc or other such
alternator with its own voltage regulator, and power it with a briggs
and strat or some such engine burning alcohol

Steve Spence at http://www.webconx.com/ethanol.htm or
Keith Addison at http://journeytoforever.org/ethanol_link.html
should be able to answer your questions.
Both sites have heaps of information - in particular, see the Alcohol Fuel
Manual on Keiths site - Chapter 2
Both post on the "Biofuels" newsgroup at www.yahoogroups.com
I think that its something to do with the amount of water still remaining
in the alcohol. Its ok if the alcohol is used by itself as a fuel (even
down to 80% purity), however if mixed with petrol/gasoline, the water will
seperate out and become a problem. If mixing alcohol with petrol, it will
need to be dried to remove the water content.
