A glow plug usually consists of a heating coil in a metal tube clogged at one end and filled with electrically insulating ceramic fine particles. The clogged end of the metal cylinder with the heating coil protrudes through an opening in the tube head into the burning chamber. When the glow plug is filled with electrical energy to the highest level, its heated part reaches a facade temperature of more than 1000°C and this takes place within a few seconds. The air-fuel spray generated by the booster ignites near the glow plug and initiates burning.

Some of the advanced glow control modules like BERU's Instant Start System (ISS) can be included into the engine running system to offer gasoline-like turn-key initial performance and added glow functions for extremely complicated emission lessening strategies.
