Abstract

Dans ce moteur, dont le pot d'échappement 22 est entouré d'une enveloppe 26, 30 distincte du capot isolant acoustique du bloc-moteur, pour éviter que les gaz d'échappement ne s'infiltrent dans l'enveloppe sous l'effet de la contre-pression produite dans le tuyau d'échappement raccordé à la tubulure 300 de l'enveloppe, on prévoit un organe de fermeture 302 qui entoure le tube de sortie 22m du pot d'échappement avec un faible jeu. Application aux véhicules automobiles.
