Promoted content: What is a Dual Mass Flywheel and how does it work?

The push for sustainability in the transport sector has driven the hybrid and electric revolution, but even conventional petrol-powered vehicles have seen significant fuel economy advancements, resulting in lower overall CO₂ emissions.

A major part of these advancements is the direct result of smaller engines. Auto makers are now designing cars with three and even two-cylinder engines, and while these smaller engines have been successful in reducing fuel consumption, they are now being asked to provide the torque and power of much bigger motors. The result is a significant increase in vibration and noise, particularly at low speeds.

How did the automotive industry deal with this increased vibration and noise? The Dual Mass Flywheel.

A DMF acts in much the same way as a traditional, single flywheel – they provide direct contact between the engine and the clutch assembly in manual transmissions. Where DMFs differ from single flywheels is more than the fact that there are two flywheels as opposed to one - it’s what happens between the two flywheels that makes all the difference.
