This is the plug that is used to help ignite the fuel in a model engine. The combustion of the fuel in the engine keeps the element hot between cycles, thus the glow plug does not need to be regulated or powered while the engine is running.
sits in the top of the motor's cylinder head and contains an electrical element that glows red hot to ignite the fuel/air mixture in the compression chamber. Glow plugs have an uncanny habit of burning out on the one day that you've run out of spare ones, and no-one else is at the flying field.
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.

The heat source for igniting the fuel/air mixture in the engine. When starting the engine a battery is used to heat the filament. After the engine is running, the battery can be removed. The wire filament inside the plug is kept hot by the "explosions" in the engine's cylinder. (See next heading and "Idle Bar" Plug.)
A device with a platinum element which initially requires a low voltage source to heat up but continues to glow and ignite the fuel air mixture on the compression cycle when exposed to the heat and pressure of combustion unlike a spark plug which requires a permanent high voltage electrical supply.
Resembles a miniature spark plug. A glow plug supplies the necessary heat for igniting the fuel/air mixture in an engine. A battery-powered unit sometimes called a glow starter is installed over the plug to heat the small wire filament inside the chamber. After the engine is running, the glow starter can be removed since the wire filament inside the plug is kept hot by the engine's "explosions within the chamber.
An electrical element located in the combustion chamber of a diesel engine which helps to heat up the air in the chamber so that the diesel will be ignited more quickly. Often they are connected in series so that when one becomes defective the others are inoperative.
