      Hello SRS,
      Butane or propane could economically fuel a small generator
      engine and run fairly clean - outdoors.
      The engine could be lubricated like an automotive engine
      with an oil reservoir and pump.
      Low compression water cooled four cycle engine exhaust can
      be muffled so quiet that it is difficult to hear the engine
      run at idle speed.
      A small generator - starting motor could be belt driven by
      the engine with a movable idler pulley to tension the belt.
      A servo could actuate the idler pulley to act as a clutch.

        Hello SRS,
        I remember SRS member Gene Elliot telling about and showing
        pictures from an annual model makers convention in central
        Oregon where he saw model miniature, running, multiple
        cylinder (V8) engines.
        Some of those model makers may have experience making small
        generators.

        Miniature steam engines and sterling engines can run on a
        great variety of fuels - even solid fuel pellets and wood
        chips and wood stove pellets.

        When air is blown into a flame as in a blacksmith forge, a
        great deal of heat can be released from even a very small
        flame. The combustion is accelerated by the increased
        available air and burns more efficiently and cleanly at a
        higher temperature with higher heat output than an ordinary
        flame. An air intensified flame can melt metal. The peak
        flame temperature depends on the fuel and air mixture.

        Complete combustion of carbon makes CO2.
        Incomplete combustion of carbon makes CO - in a lack of
        oxygen.
        Some incomplete combustion releases CH hydrocarbons and
        sulfur compounds like SO2. (Some fuels contain sulfur as
        impurities). Automotive emissions (smog) test these levels -
        by an automatic, if not robotic - air sampling dynamometer
        machine.
        An ideal fuel like hydrogen burns (oxidizes) to make plain
        H20 - water!
