Abstract

La présente invention concerne un dispositif d’échappement de produits de combustion d’un moteur endothermique à deux temps présentant une section d’entrée (1a) en communication fluidique avec le moteur endothermique et au moins une première section de sortie (1b) du produit de combustion dans l’atmosphère ; le dispositif comprend au moins une unité catalytique (3) des produits de combustion, un silencieux (5), placé en aval de l’unité catalytique (3), et une unité filtrante (6) des produits de combustion ; un organe d’interception (7) est configuré pour passer d’au moins une première position fonctionnelle d’exclusion du passage des produits de combustion dans le conduit d’entrée (6a) de l’unité filtrante (6), à une seconde position fonctionnelle d’admission des produits de combustion dans le conduit d’entrée (6a) de l’unité filtrante (6), et vice versa ; l’organe d’interception (7) est configuré pour passer de la première position fonctionnelle à la seconde position fonctionnelle dans une condition de démarrage du moteur endothermique et pour passer de la seconde position fonctionnelle à la première position fonctionnelle après que l’organe d’interception (7) ait passé un certain temps dans la seconde position fonctionnelle.
