Abstract

L'invention concerne un moteur à combustion interne comportant un dispositif pour réduire la pression des gaz d'échappement Un moteur selon l'invention comporte un groupe turbocompresseur 4, 20 dont la turbine reçoit les gaz d'échappement du moteur, les gaz passant ensuite à travers un échangeur de chaleur 6 refroidi par de l'air et un échangeur de chaleur 10 refroidi par un liquide pour le refroidissement des gaz basse pression avant leur passage à travers le compresseur, les gaz échappant ensuite dans l'atmosphère à travers un tuyau d'échappement 22. Un moteur selon l'invention convient en particulier pour un véhicule automobile.
