Harmonic Balancer - Crankshaft Pulley: Description and Operation

Torsional vibration balancer

A torsional vibration balancer is used to reduce torsional vibrations on the crankshaft and to minimize component stress, e.g. on the belt drive.







A shock absorber with the very best damping characteristics was selected because of the greater power impulses associated with direct fuel injection engines.

The viscous shock absorber has a floating flywheel in silicon oil in the housing. This allows the counter-movement of the bearing mass to a not quite evenly rotating crankshaft. This system also features an optimised fixing bore compared to the previous engine.
