Dual Durameter Blow Molded Rocker Cover Design With Unique Isolation Strategy
Abstract
The rocker arm cover on a diesel engine can be formed of a rigid molded plastic material to minimize the transmission of noise into the atmosphere. Sonic vibration of the cover can be reduced by reducing the cover material stiffness. The reduced stiffness of the cover material allows the roof area of the cover to be momentarily displaced away from the cylinder head in the presence of an acoustic wave, so that the roof area is not able to develop the restoring force that is necessary for vibrational motion.
