Self-regulating ceramic glow plugs from NGK

Self-regulating ceramic glow plugs (also called "SRC glow plugs" for "Self Regulating Ceramic") are equipped similarly to the self-regulating metal rod glow plugs, with one heating coil and one control coil.

Since the electrical resistance of the control coil increases as the temperature increases and thereby limits the current flow, this glow plug requires practically no external control.

This glow plug type heats up to over 1,100 °C in 3 seconds and then independently regulates the temperature to below 1,000 °C.
