Abstract

A linking arm conveying generally linear movement from a piston into generally radial movement of a crankshaft is disclosed. The linking arm includes a shaft extending between a piston pin end and a crankshaft pin end. The piston pin end defines a piston pin bore. A piston pin bore surface is defined by the piston pin bore, where the piston pin bore includes a non-circular transverse profile having at least two curved surfaces that each include a distinct radius, where the at least two curved surfaces are positioned in different locations around a periphery of the transverse profile.
