Abstract

Procédé (20) d'estimation de la température (T(t)) du crayon des bougies de préchauffage implantées dans une chambre de combustion d'un moteur à combustion interne, notamment de type Diesel, comprenant au moins un capteur de pression de cylindre (Pcyl), dans lequel en mesurant la pression de cylindre (Pcyl), pour chaque position de vilebrequin, en connaissant la tension de pilotage de la bougie, en initialisant la température de la bougie (T(t)) au premier pas de calcul moteur froid, à la température de la culasse, ou à la température précédente en cas de démarrage à chaud, on estime une valeur de température moyenne dans le cylindre sur un cycle de combustion (Tgaz(cycle)) et par pas de calculs itératifs, on estime la température (T(t)) du crayon des bougie.
