Abstract

In addition to the function of fresh air intake and filtering, automotive intake system is usually also required a good acoustic characteristics and the effective control of the engine intake noise. The impact of different structure parameters to the flow field of the intake system is analyzed in the paper, the one-dimensional porous jump model is applied to model the filter paper. Meanwhile, silencing component is added to the intake system to degrade the noise peak value and improve silencing performance at low-frequency. The comparison of the simulation and testing results shows good agreement. It is proved that the acoustic performance of the intake system has been greatly improved after adding the silencing component.
