[Gasification] ideal wood gas engine

[Daniel Chisholm]

For what it's worth:

   - preignition, piston clatter (slap), and pinging are three different
   things
   - pinging is detonation
   - a fuel's octane rating is not a measure of its energy content nor of
   how fast it can be made to burn.  Octane rating is a measure of a fuel's
   resistance to detonation.  Typically (and counterintuitively) a higher
   octane fuel is slower burning
   - burn rate is not a constant, among other things it depends on pressure
   and temperature, both of which change as a piston moves and also as a
   function of how much burning has already happened
