Diesel Glow Plugs Replacement
Diesel Glow Plugs Replacement
It is possible to start a warm diesel engine without using a glow plug, or in warm climates, thanks to the relatively high temperature of the intake air and the relatively low ignition temperature of diesel. However, this isn’t enough to ensure proper ignition of the injected fuel in all temperatures, which results in increased exhaust emissions. A diesel glow plug solves this issue. It is an electrical heating device located in each cylinder of the diesel engine that ensures reliable starts in all weather conditions.

How long do glow plugs last?
Unlike a spark plug that is working continuously while you drive, glow plugs are only needed during the ignition process. The glow plugs work by electrifying the heating element so it heats up and emits visible light (hence the name). Intake air is compressed before the fuel injector spray directs fuel onto the hot tip of the glow plug during the injection of the fuel. The injected fuel mixes with the compressed air to evaporate and start combustion almost simultaneously, even when the engine is cold.
