A diesel glow plug, simply known as glow plug, is an electrical heating device found in the combustion chamber of a vehicle with a diesel engine. It provides the heat required to induce combustion. A diesel engine does not use spark plugs and since its combustion process requires the use of a very large engine block, the engine block becomes cold when not running especially during cold weather which then acts as a heat sink that dissipitates any heat generated by the pistons. Glow plugs provide the heat needed to ignite the fuel, which then starts the engine. A defective glow plug will prevent a diesel-powered vehicle to start.
