Glow Plug
Similar to a spark plug in a car's internal combustion engine, the glow plug is a filament that literally glows in order to ignite the fuel inside the engine cylinder. When a glow engine is first started, a "glow ignitor" is attached to give the filament a very high temperature. Once heated, a catalytic reaction between the methanol in the fuel and the platinum in the coil keeps the latter glowing, thus providing a continued source of ignition once the engine has been started and glow ignitor is removed.
