Glow Plug: Operation

The glow plugs are used to preheat the combustion chambers in order to achieve the ignition temperature required for the fuel-air mixture.

The heating element is integrated in the glow rod. It consists of a heating winding and a control winding connected in series.

The glow plug system is a quick start type. This allows for immediate start in practically all weather conditions without long periods of pre-glowing. This works in conjunction with 6-hole injectors, which have a special "ignition" spray pattern. The glow plugs reach 1000°C (1832°F) in 2 seconds.
