The crankshaft is the most important component of the engine. It is subject to the forces transmitted by the connecting rods and transforms them into torque that is output through the crankshaft and drives the other accessories on the engine. The crankshaft is subjected to the combined effects of centrifugal forces of the rotating mass, cyclically varying gas inertia forces and reciprocating inertia forces, which subject the crankshaft to bending and torsional loads. The crankshaft is therefore required to have sufficient strength and stiffness, and the journal surfaces must be wear-resistant, uniform and well-balanced.
