Abstract
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.
