Abstract:
The paper describes the identification and control methods of turbocharger surge noise. Some parameters, such as temperature, flow quantity, pressure, vibration, turbocharger rpm and noise, are provided to identify surge noise. The advantages and disadvantages for each parameter are analyzed.The paper identifies that some special vehicle interior noise is contributed by turbocharger surge noise by using correlation analysis of the turbocharger inlet temperature, outlet pressure and vehicle internal noise. Spectral filtration analysis shows that the surge noise frequency components are above 1000Hz with wide frequency band. Quarter wave tuner's effective frequency range is found to be consistent with the surge noise frequency band. A panfluter-resonator which is a combination of several special quarter wave tuners is invented to diminish the wide band high frequency noise. After the panfluter-resonator is installed on a turbocharger system, the vehicle interior surge noise is significantly reduced.
