Development of a Plastic Manifold Noise Syntheses Technique 2001-01-1144

The effects of engine noise in plastic manifolds has been a subject of study in the automotive Industry. Several SAE papers have been published on the subject. Most testing described requires access to engine dynamometers and other elaborate equipment. As part of a general study of plastic intake manifold noise characteristics, this study was undertaken to develop a synthesis bench for enabling low cost noise testing of plastic induction systems including plastic manifolds.

Computer simulation of engine intake noise was used as part of a correlation between the plastic manifold synthesis bench and actual engine measurements.

The Fast Fourier Transform (FFT) analysis provided analogous results between the predicted theoretical and two measured signals with a fundamental frequency at approximately 80 Hz. Qualitative and statistical comparisons of the time domain signals also proved equally favourable.

Recommendations are included for further development of this approach.
