Abstract

On propose un procédé pour détecter la contre-pression de gaz d'échappement dans un moteur à combustion interne à turbocompresseur, dans lequel un point de fonctionnement de la turbine est déterminé en prenant en compte la pression de gaz d'échappement en aval de la turbine. Un quotient de pression est ensuite obtenu à partir du point de fonctionnement en appliquant un modèle de turbine. Un calcul de la contre-pression de gaz d'échappement s'effectue à partir du quotient de pression et de la pression de gaz d'échappement en aval de la turbine.
