GLOW PLUGS
Ceramic glow plugs
There are two types of ceramic glow plugs:
1. Quick-start glow plugs
The temperature rise if very rapid – faster than in quick-start sheathed type glow plugs. The voltage generated is precisely controlled by a special control unit or glow relay.
2. Self-regulating glow plugs
Comparable with the “pencil” – self-regulating ceramic glow plugs are also equipped with a heating and voltage regulating control coil. The latter reduces the current intensity as the temperature increases.
Properties:
Faster temperature rise and conductivity
Note:
This type of glow plug needs hardly any external control as it is self-regulating.

| Type of glow plug | Preheating times | ||
| Ceramic glow plug | self-regulating | e.g. CY01 | approx. 4 Sec. to 900°C |
| Ceramic glow plug | Quick-start-glow plug | e.g. CZ01, CX01 | approx. 3 Sec. to 900°C |
