Some of the features of the ceramic glow plugs that are used on the 6.7L Power Stroke® diesel are:
• End of compression temperature is high enough to auto-ignite the fuel.
• The ceramic glow plugs can reach 1250°C (2282°F) in 2 seconds.
• The tip of the glow plug is closer to the rim of the piston than the injector. This causes the heat from the glow plug to contact the rim zone of the fuel spray.
