TURBO CHARGER HAVING NVH-REDUCING DEVICE

摘要

A turbo charger having a noise, vibration and harshness (NVH)-reducing device, includes: a central housing including a bore into which a shaft having a turbine wheel coupled to one side thereof and a compressor wheel coupled to another side thereof is inserted; a turbine housing disposed at the one side of the central housing, and in which an exhaust gas inlet and an exhaust gas outlet are formed and the turbine wheel is disposed; a compressor housing disposed at the other side of the central housing, and in which an air inlet and an air outlet are formed and the compressor wheel that compresses air introduced from the air inlet when the turbine wheel is rotated and moves the compressed air toward the air outlet is disposed; and an air-alleviating portion that is disposed between the air inlet and the air outlet of the compressor housing and alleviates a flow of air that occurs when the compressor wheel is rotated.
