Abstract
A crankshaft for an internal combustion engine includes a shaft body having a body rotation axis, with at least one crank pin for coupling a connecting rod to the crankshaft. The crank pin is connected to the shaft body in an offset manner with respect to the body rotation axis by two crank arms. Each arm has an arm surface facing one to the other with the crank pin extending between the arm surfaces. At least one of the arm surfaces is provided with a protrusion extending from the arm surface and configured to avoid contact between the arm surface and the connecting rod.
