Ignition Control
Fig. 26: Glow Plug

Glow plugs are used to help start a cold or cool engine. The glow plugs will heat up and glow to heat the combustion chamber of each cylinder. An individual glow plug is used for each cylinder. Each glow plug is threaded into the cylinder head below the cylinder head cover.


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 preglowing. This works in conjunction with 6-hole injectors, which have a special "ignition" spray pattern. The glow plugs reach 1000º C (1832º F) in 2 seconds.
