Automatic transmission (CVT) 01J
With reciprocating engines, torsional vibrations are produced at the crankshaft due to irregularity of the combustion process.
The torsional vibrations are transmitted to the transmission where they cause resonant vibrations. This results in noise and excessive stress on the components.
In 6-cylinder engines the engine torque is transmitted to the transmission via a flywheel damper unit in order to prevent the torsional vibrations from entering the transmission.
