Connecting rod for engine

A reciprocating machine comprising a cylinder block having at least one cylinder bore formed therein, a piston reciprocating in said cylinder bore, a crankshaft journaled for rotation about a first axis relative to said cylinder block, a connecting rod for transmitting reciprocation of said piston into rotation of said crankshaft about said first axis, said connecting rod having a small end defining a cylindrical bearing opening having an axis for receiving a piston pin, means for coupling said piston pin to said piston for transmitting motion from said piston to said connecting rod, the other end of said connecting rod comprising a big end split into two pieces defining a cylindrical crankshaft bearing opening having an axis that extends parallel to said first axis and which axis is parallel to the axis of said cylindrical bearing opening of said small end of said connecting rod and is in a common plane therewith, at least two threaded fasteners being disposed on opposite sides of said connecting rod for fixing said two pieces of said big end together in embracing relationship with a throw of said crankshaft, the center of gravity of said connecting rod being offset from a first plane perpendicular to said common plane and passing through an axial center of said crankshaft bearing opening, said at least two threaded fasteners having axes lying on a plane containing the said center of gravity and extending parallel to said first plane.
