Abstract

La présente invention concerne une configuration destinée à fournir un milieu à une ligne (3) d'échappement de moteur (1) à combustion. La configuration comporte une ligne (3) d'échappement pour extraire les gaz d'échappement du moteur (1) à combustion, une turbine (4) disposée dans la ligne (3) d'échappement pour convertir l'énergie des gaz d'échappement en travail mécanique, un moyen (13) d'injection disposé dans la ligne (3) d'échappement afin d'injecter un milieu liquide dans la ligne (3) d'échappement, suite à quoi il est prévu que le milieu liquide soit chauffé et vaporisé par les gaz d'échappement chauds dans la ligne (3) d'échappement. Le moyen (13) d'injection est installé sur la ligne d'échappement à un emplacement (3a) tel qu'il injecte le milieu liquide en amont de la turbine (4) par rapport à la direction d'écoulement des gaz d'échappement dans la ligne (3) d'échappement. (Fig. 1)
