The paper exemplifies the necessity to quantify the various noise sources present in modern automotive engines.Results demonstrate the non-linearity problems associated with many of the non-running engine rig tests currently in use.A new technique is described for combustion induced noise simulation using hydraulic excite ion. Results obtained using this experimental method are compared with those measured on the running engine.
