Glow fuel
Methanol is the main ingredient.  It provides most of the fuel's ability to burn.  In order to burn the glow fuel, a glow engine must have a glow plug.  The glow plug burns very hot as the engine runs because of a catalytic reaction with the methanol.  Since the engines turn very fast, a phenomenon known as thermal inertia helps to keep the plug glowing as the engine runs.  A small amount of electricity is used to cause the glow plug to glow as the engine is started.  Once the engine is running, the electricity is disconnected.
