Abstract

La présente concerne un procédé de correction d’une richesse d’un mélange d’air/carburant alimentant un moteur (1) à combustion interne dans la période comprise entre un démarrage du moteur (1) et l’atteinte de la température de fonctionnement d’une sonde à oxygène (6) positionnée dans une ligne d’échappement (2) du moteur (1), dans lequel on détermine une consigne (Cr) de richesse, et à partir de cette consigne (Cr) une quantité de carburant à injecter dans le moteur (1), on mesure au démarrage du moteur (1) une température (T) représentative de l’état thermique du moteur (1), on chauffe la sonde à oxygène (6), caractérisé en ce que l’on détermine en fonction de la valeur de cette température représentative (T), un facteur correctif (Fcr) à appliquer à la quantité de carburant à injecter, et on applique ce facteur correctif (Fcr) jusqu’à ce que la sonde à oxygène (6) ait atteint sa température de fonctionnement.
