I have been following a website that is promoting Mazda type rotary
engines for light aircraft. With only 3 moving parts, there are a lot
less things to go wrong. You almost always make it home and they are
cheap to fix. They started talking about using acetone as an additive to
speed up the combustion so that all the fuel is burned from the sparking
of 2 spark plugs. They were speaking of a fast moving combustion front
and I thought that this may be an ideal home for Butanol. Butanol for
rotary engines. I have been asked how much it costs. It would seem to me
that with the way that gas is going, it may be cheaper to use butanol in
planes. Can you help me and would you like to speak with Paul Lamar at
the above website?
