Dual mass flywheels

Why are dual-mass flywheels used in modern cars?

• To increase engine size

• To decrease fuel efficiency

• To reduce engine harmonics

• To make cars heavier

What connects the primary and secondary masses in a dual-mass flywheel?

• A chain

• A rubber band

• A compression spring damper system

• A metal rod

How do progressive arc spring designs help in dual-mass flywheels?

• They reduce the size of the engine

• They increase fuel consumption

• They allow for a soft damping effect at low speeds

• They make the flywheel heavier

What should be checked when inspecting a dual-mass flywheel?

• The color of the car

• The size of the tires

• Severe grooving and grease leakage

• The type of fuel used

Why do manufacturers not recommend replacing a dual-mass flywheel with a solid conversion kit?

• It makes the car faster

• It improves fuel efficiency

• It increases undamped vibrations

• It reduces the car's weight
