Abstract

L’invention concerne un moteur à combustion interne (1) comprenant : - une chambre de combustion, - une ligne d’admission (20) d’air frais, - une ligne d’échappement (80) de gaz brûlés qui comprend au moins un convertisseur catalytique (83), - un turbocompresseur (30) qui comporte une turbine (82) et un compresseur, et - une pompe à vide (40) qui comporte une entrée (41) par laquelle elle est adaptée à aspirer de l’air et une sortie (42) par laquelle l’air aspiré est expulsé. Selon l’invention, la turbine est située en aval du convertisseur catalytique, il est prévu une ligne de soufflage (50) qui comprend une réserve d’air (52), et qui communique, d’un côté, avec la sortie de la pompe à vide et, de l’autre, avec la ligne d’échappement en amont du convertisseur catalytique, et il est prévu au moins une vanne de régulation (51) adaptée à réguler le débit d’air circulant dans la ligne de soufflage.
