Abstract

L'invention porte sur un procédé de commande d'un échappement d'un ensemble moteur (1) thermique d'un véhicule automobile comprenant un système d'échappement logeant une turbine (2) d'un turbocompresseur, l'échappement présentant un premier flux par turbine provenant du premier passage traversant la turbine (2) logeant une roue de récupération partielle d'une énergie contenue dans les gaz et un deuxième flux de décharge provenant du deuxième passage rejoignant le premier flux en aval de la roue en la contournant. Il est effectué une augmentation forcée de pression du deuxième flux pendant la durée d'ouverture commune pour un retour d'au moins une partie du deuxième flux dans ledit au moins un cylindre pour des conditions de pleine charge sous un régime moteur inférieur à 3000 tours par minute ou de charge partielle du moteur sous une pression moyenne effective de moins de 106 Pascals.
