Abstract

Le collecteur d'échappement (10) pour moteur à combustion interne multicylindre comporte quatre conduits d'entrée (21, 22, 23, 24) connectés par une tubulure de traverse (12) à un conduit de sortie des gaz d'échappement (14). Les conduits d'entrée extérieurs (21 et 24) portent chacun une bride de raccordement à la culasse séparée (26 et 28). Les conduits d'entrée intérieurs (22 et 23) sont reliés par une bride d'entrée double centrale (30) solidaire de la bride de sortie (38) portée par le conduit (14), la bride double (30) étant séparée des brides extérieures (26) et (28). Des voiles de renfort (48, 49 et 50) sont solidarisés aux inter-conduits (12a, 12b et 12c).
