Abstract

Le refroidissement de l'air comprimé par un turbocompresseur à gaz d'échappement à l'aide d'un refroidisseur d'air de suralimentation avant son entrée dans le moteur à combustion interne est un procédé connu. En raison des températures relativement élevées de l'air comprimé, il est nécessaire de concevoir les refroidisseurs d'air de suralimentation en conséquence, c'est-à-dire qu'il est nécessaire d'avoir recours à un prérefroidisseur. La présente invention concerne donc un moteur à combustion interne (1) pourvu d'un turbocompresseur à gaz d'échappement (2) comportant un compresseur (4), logé dans un carter (4) de compresseur, qui refoule l'air comprimé dans une conduite d'air de suralimentation (11) et l'envoie dans le moteur à combustion interne (1) via un refroidisseur d'air de suralimentation (15). Selon la présente invention, un segment (10) de la conduite d'air de suralimentation (11) situé entre le refroidisseur d'air de suralimentation (15) et le compresseur (4) est refroidi à l'aide d'un fluide de refroidissement s'écoulant dans ledit segment (10) de la conduite d'air de suralimentation (11). Cela permet de simplifier la structure du refroidisseur d'air de suralimentation (15) adjacent et plus précisément de supprimer le prérefroidisseur qui aurait sinon été nécessaire. La présente invention est destinée aux moteurs à combustion interne comportant un turbocompresseur à gaz d'échappement en vue de la suralimentation de l'air aspiré.
