Summary:

Two problems that arise in induction system acoustic analysis are addressed in the context of the Acoustic Wave Finite Element (AWFE) procedure. A source model that makes use of measured data to scale the source amplitude is shown to provide good correlation between the predicted and measured inlet manifold noise of a six cylinder engine. Three-dimensional effects due to complex geometry in intake manifolds and air cleaners are modeled using an extension of the AWFE method that introduces three-dimensional wave structure within elements that are comparable to the acoustic wave length. Comparisons are made of the acoustic output of induction system components modeled using simple plane wave elements and using elements with wave structure
