turbocharger system having noise reduction function

摘要

PURPOSE: A turbocharger system having noise reduction function is provided to reduce the noise by changing the transmission path of the noise generated at a turbocharger. CONSTITUTION: A turbocharger system having noise reduction function comprises an air intake pipe line(12) receiving an outer air purified by an air cleaner, a compressor wheel installed to the air intake pipe line to be rotated, an intake pipe line for turbocharged air receiving an intake air compressed by the compressor wheel, an engine connected to the intake pipe line for turbocharged air, an exhaust gas pipe line which an exhaust gas is passed through, a turbine wheel installed to the exhaust gas pipe line and rotated by the flow of the exhaust gas, and a rotation shaft connecting the turbine wheel and the compressor wheel to be communicated each other, wherein a protrusion part(12a) is protruded from the outer circumference surface of the air intake pipe line.
