Glow Plug

An electrical device used to heat the air in the combustion chamber of a diesel engine for quick ignition and starting when the engine is cold.

A diesel needs to achieve an air temperature of 850°C to start. The glow plug assists in bringing the air in the combustion chamber up to this temperature so that the engine will start.

Glow plugs operate at a temperature of 850°C to 1100°C.

The steady state current draw is around 10 to 12Amps for each glow plug.
