Profiled connecting rod bore with micro-dimples |
摘要 |
A connecting rod and methods for making the same are disclosed. A connecting rod may include a shaft extending between a piston pin end and a crankshaft pin end. The piston pin end generally defines a bore opening extending along an axis. The connecting rod further includes a bore surface formed integrally with the piston pin end and extending about an inner circumference of the bore opening. The bore surface may define a plurality of dimples that extend axially along the bore surface. The bore opening further may further include profiled surfaces adjacent opposing ends of the bore opening.
