Abstract
A cover assembly for an engine includes at least one relatively large mounting wall portion potentially subject to induced vibrations that transmit undesirable noise or sound to the exterior of the engine. To reduce the vibration and resulting noise, a pair of vibration damping plates is attached to the interior of the mounting wall portion and urged against the wall portion. The damping plates may be made from untreated steel when mounted in a lubricating oil atmosphere which serves to protect the plates against oxidation. The plates have different thicknesses selected to provide differing vibration frequency responses that act to create damping between the plates and the associated cover wall portion.
