Abstract

Circuit d’admission d’air à l’échappement d’un moteur à combustion interne. L’invention porte sur un circuit d’admission d’air à l’échappement (30) d’un moteur à combustion interne (2) comprenant au moins un cylindre (10) et une culasse (20), caractérisé en ce que le circuit d’admission d’air à l’échappement (30) comprend une chambre principale s’étendant selon un premier axe (A1) orthogonal ou sensiblement orthogonal à l’axe principal (A2) de l’au moins un cylindre (10) et parallèle à la face d’échappement de la culasse, la chambre principale étant connectée en amont selon le sens de circulation de l’air à un circuit d’admission d’air frais d’un tel moteur à combustion interne (2) et en aval à l’au moins un conduit d’échappement.
