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.The invention relates to a method for controlling an exhaust of a thermal engine assembly (1) of a motor vehicle comprising an exhaust system housing a turbine (2) of a turbocharger, the exhaust having a first turbine flow from the first passage passing through the turbine (2) housing a wheel for partial recovery of an energy contained in the gases and a second discharge flow from the second passage joining the first flow downstream of the wheel bypassing it. A forced increase in the pressure of the second stream is carried out during the period of common opening for a return of at least part of the second stream in said at least one cylinder for full load conditions under an engine speed of less than 3000 rpm. per minute or partial engine load at an average effective pressure of less than 106 pascals.
