The main function of the glow plug in diesel engines is to provide additional energy to start the engine. Before the engine starts, the glow plug is heated to a high temperature (around 750–850 degrees Celsius ) and as a result the glow tube starts glowing. This heat makes sure that enough heat is provided to start an engine.
