Flywheel: Description and Operation
OPERATION
The flywheel serves to dampen the engine firing pulses. The heavy weight of the flywheel relative to the rotating mass of the engine components serves
to stabilize the flow of power to the remainder of the drivetrain. The crankshaft has the tendency to attempt to speed up and slow down in response to the
cylinder firing pulses. The flywheel dampens these impulses by absorbing energy when the crankshaft speeds and releasing the energy back into the
system when the crankshaft slows down.
On a Dual Mass Flywheel, the additional secondary mass coupled to the transmission lowers the natural frequency of the transmission rotating elements.
This decreases the transmission gear rattle. The damper springs between the two flywheel masses replace the clutch disc damper springs and assist in a
smooth transfer of torque to the transmission.
CAUTION: The Dual Mass Flywheel is serviced as an assembly only and should never be disassembled.
