Simulation of Combustion Induced Noise in a Non-Running Engine Structure by Impulsive Hydraulic Excitation 820364

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.
