What is the primary purpose of a diesel engine's viscous damper?
The primary purpose of a diesel engine's viscous damper, also known as a torsional vibration damper, is to control and minimize torsional vibrations in the crankshaft. Torsional vibrations are twisting oscillations that occur along the length of the crankshaft due to the cyclical nature of combustion and the inertia of the rotating components. Each time a cylinder fires, it applies a torque pu....

“Th eprimary purpose of a diesel engines viscous damper also know as a torsional vibration damper is to control and minimize torsional vibrations in the crankshaft. Torsional vibrates are twisting iscillations that occur along the length of the crankshaft due to the cylindrical nature of combustion and inertia of the otating components. Each time a cylinder fires it applies a torque pulse to the crankshaft which causes it to twist and untwist. These vibrations if left unchecked can lead to excessive stress concentration in the crankshaft.”
