The clutch used in most light vehicle applications is a single plate friction type. The clutch transmits torque from the engine to the transmission and a release mechanism allows the driver to control the flow of torque between them.
The dual mass flywheel eliminates excessive transmission gear rattle, reduces gear change/shift effort, and increases fuel economy. The function of the dual mass flywheels is to isolate torsion crankshaft spikes created by diesel engines with high compression ratios.
The clutch operating mechanism may be mechanical or hydraulic. When the clutch pedal is depressed, the movement is relayed to a release fork which carries the release bearing.
