9. DUAL MASS FLYWHEEL (DMF) & DRIVE PLATE
1) Overview
Flywheel is installed on crankshaft. When
starting the engine, this functions as follows:
Reducing the irregular speed of crankshaft
due to unbalanced combustion ->
Improving the power train NVH, Improving
the driving performance
Reducing the clutch noise by using ball
bearing
Improving the durability of DMF by using
strong arch spring -

Torque change curve of engine and drive shaft
Compression stroke Combustion stroke
Small changes from engine (k):
Damper increases the torque changes to clutchLarge changes from engine (j):
Damper decreases the torque changes to
transaxle by absorbing the impact
3) Operation
Compensating the irregular operation of engine: The secondary flywheel operates almost
evenly so does not cause gear noises
The mass of the primary flywheel is less than conventional flywheel so the engine irregularity
increases more (less pulsation absorbing effect).
Transaxle protection function: Reduces the torsional vibration to powertrain (transaxle) by
reducing the irregularity of engine. -

1. SYSTEM DESCRIPTION
The starter (start motor) starts the engine with rotational power by converting the electric energy to
the mechanical energy.
When the engine is cranking, the pinion gear meshes with the ring gear. If the ring gear overruns,
the pinion gear clutch overruns to protect the pinion gear.

5) Normal Cancellation of the Cruise Control
The cruise control system will be canceled when one or more items of the following conditions
are applied;
When the brake pedal is depressed or When ESP is activated.
When the cruising speed is downed less than 34 km/h
When applying the parking brake during driving.
When using the clutch in order to shift (M/T only). 1.

3.
4.
Keep the main cruise control switch in the neutral position when not using the cruise control.
