Abstract (en)
[origin: WO2007140922A1] A method for controlling a glow plug in a diesel engine, in particular in the preheating phase, is described. According to the invention, it is provided that the time gradient of an electrical variable which varies according to the temperature of the glow plug is measured and compared with a threshold value, and when said time gradient exceeds or drops below the threshold value, the electric supply voltage of the glow plug is changed.
