Glow plugs are mounted in the engine block in such a way that the heating tip is located in the intake manifold chamber. The rapid increase in the temperature of the glow plug tip is caused by the current that flows through the glow plugs when the ignition key is turned to the glow plug heating position. The rapid increase in the temperature of the glow plug tip heats the air, and the heated air sucked further into the engine facilitates ignition and starting the engine.
