Dual Mass Flywheel DMF
Technology at a glance
Technical requirements:
 Higher torque levels
 Higher ignition pressures
 Stricter emission controls
 Greater requirements for comfort
and noise control
 Protection of gearbox and vibrationsensitive vehicle components
all require extremely high-performance torsional dampers
