Abstract

L'invention concerne un procédé de détermination du point de rosée, dans une partie de ligne d'échappement (2) reliée à un moteur (1) à combustion interne, caractérisé en ce que -on détermine l'énergie calorifique libérée dans la ligne d'échappement depuis le démarrage du moteur, -on détermine le nombre d'arrêts moteur consécutifs antérieurs sans passage de point de rosée, -on détermine un seuil d'énergie calorifique pour lequel on considère que le point de rosée est passé, ce seuil étant le produit d'un seuil de base prédéterminé d'énergie calorifique libérée dans la ligne d'échappement depuis le démarrage du moteur, d'un facteur dépendant du nombre déterminé d'arrêts moteur consécutifs antérieurs sans passage de point de rosée, et d'un coefficient de sécurité, -on compare l'énergie calorifique libérée dans la ligne d'échappement à ce seuil et on considère alors que le point de rosée est passé si l'énergie calorifique est supérieure au seuil d'énergie déterminé.
