In a car, the crankshaft or the crank is a device that is used to translate reciprocating linear piston motion into rotation. It typically connects to a flywheel, to reduce the pulsation characteristic of the four-stroke cycle, which creates a torsional or vibrational damper at the opposite end in order to reduce the torsion vibrations caused by the length of the crankshaft. Given the crank's tedious task to give the engine its highest optimization, it needs to allow a continual refreshment of...
