Summary:

A predictive technique aimed at investigating the behaviour of intake and exhaust systems of internal combustion engine and at evaluating their influence on engine breathing and radiated noise is herewith presented. Such a technique is based on coupling a time domain gas dynamic model (composed of zero-dimensional, one-dimensional and three-dimensional methods) with a frequency domain linear acoustic analysis (transfer matrix method); thus a realistic prediction of complete engine systems is realised by adopting in each region the most appropriate method, according to the main features of the phenomena involved. The whole procedure has been applied to the intake system of an automotive engine and the results regarding different operative conditions are presented
