Abstract

L'invention concerne un moteur à combustion interne (1) comprenant : - un bloc-moteur (10) qui comporte au moins un cylindre (11), - une ligne d'admission (20) de gaz frais dans chaque cylindre, - une ligne d'échappement (80) de gaz brûlés hors de chaque cylindre, - un turbocompresseur qui comprend une turbine (82) située dans la ligne d'échappement et un compresseur principal (22) situé dans la ligne d'admission, - un compresseur électrique (26) situé dans la ligne d'admission, et - une ligne de recirculation (30) des gaz brûlés qui prend naissance dans la ligne d'échappement et qui débouche dans la ligne d'admission. Selon l'invention, la ligne d'admission comporte deux branches parallèles (20A, 20B) qui se rejoignent, dont une première branche (20A) qui comprend le compresseur principal et une seconde branche (20B) qui comprend le compresseur électrique, et la ligne de recirculation débouche dans la seconde branche, en amont du compresseur électrique. L'invention concerne également un procédé de commande du moteur à combustion interne équipant un véhicule automobile.
