摘要:
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.
