Glow plugs task	To preheat the prechamber or combustion chamber in order to achieve the necessary ignition temperature for fuel-air mixture.
Glow plugs design		GF15.20-P-3101-02H
Glow plugs function	When the preglow system is switched on, a current of about 30 A flows to each glow plug. The heating winding heats the glow plug. The control winding increases its resistance as the temperature rises and limits the current to approx. 15 - 25 A. This protects the glow plugs (R9) from overload
