要約
(EN)
The object of the invention is to suppress the generation or accumulation of deposits in a compressor of a turbocharger of an engine provided with a blowby gas recirculation device. The invention relates to a cooling device for the turbocharger (60) of the engine (10) provided with the blowby gas recirculation device (50). The cooling device has a cooled air introduction passage (70). The blowby gas recirculation device introduces a blowby gas to an area upstream of the compressor. The cooled air introduction passage introduces a cooled air to a diffuser passage (64) of the compressor. The cooled air introduction passage introduces the cooled air to the diffuser passage in a direction having an acute angle with respect to a flow direction (IA) of the intake air flowing through the diffuser passage.

La présente invention vise à supprimer la présence ou l'accumulation de dépôts dans un compresseur d'un appareil de suralimentation dans un moteur à combustion interne comprenant un dispositif de circulation de gaz perdu. La présente invention concerne un dispositif de refroidissement d'un appareil de suralimentation (60) d'un moteur à combustion interne (10), comprenant un dispositif de circulation de gaz perdu (50). Le dispositif de refroidissement comprend un passage d'entrée d'air de refroidissement (70). Le dispositif de circulation de gaz perdu introduit un gaz perdu en amont d'un compresseur. Le passage d'entrée d'air de refroidissement introduit l'air de refroidissement dans un passage de diffuseur (64) du compresseur. Le passage d'entrée d'air de refroidissement introduit l'air de refroidissement dans le passage de diffuseur à un angle aigu par rapport à la direction de flux (IA) de l'air d'admission passant par le passage de diffuseur.
