The crankshaft. sometimes casually abbreviated to crank. is the part of an engine which translates reciprocating linear piston motion into rotation. It typically connects to a flywheel. to reduce the pulsation characteristic of the four-stroke cycle. and sometimes a torsional or vibrational damper at the opposite end. to reduce the torsion vibrations often caused along the length of the crankshaft by the cylinders farthest from the output end acting on the torsional elasticity of the metal.
