Dual Mass Flywheel

How do dual mass flywheels work? What is a dual mass flywheel? DMFs have two masses (really!). The first mass is matched with the engine crank, and it transfers engine torque through springs to another mass, which is connected with the transmission (and clutch housing). The goal is to reduce torsional vibration through the drivetrain, which is particularly useful for diesel engines, low idle speeds, and low cylinder counts.
