Abstract

La présente invention concerne un moteur à combustion interne suralimenté comprenant un compresseur placé sur le trajet d'une conduite d'admission (1) dont une partie située en amont de l'entrée du compresseur est séparée intérieurement en au moins deux canaux (21, 22) parallèles, et une conduite de recirculation (9) piquée sur la conduite d'admission (1) de part et d'autre du compresseur, cette conduite de recirculation présentant une sortie qui débouche dans un des canaux (22) de ladite partie de la conduite d'admission.
