Abstract (en)
[origin: WO2012113653A1] The invention relates to a method for adjusting a temperature of a glow plug, in particular for igniting a fuel/air mixture in an internal combustion engine, wherein the temperature (Tm) of the glow plug (2) is adjusted by means of a regulating system dependent on a resistance (Rm) of the glow plug (2). The aim of the invention is to prevent the occurrence of temperature overhoots during the pre-heating phase of the glow plug. This is achieved in that the temperature (Tm) is regulated using a predictive model (8) in a pre-heating phase in which an overvoltage is applied to the glow plug (2).
