| 20100206261 | HIGH-FLOW CYLINDER LINER COOLING GALLERY - A cylinder liner for an internal combustion engine and a method of making the same are disclosed. The cylinder liner may generally include a cylindrical body configured to receive a piston assembly. The cylindrical body may further include a main body portion configured for selective engagement with an engine bore, and an upper flange configured to support the cylindrical body within the engine bore. The cylindrical body may also define an undulating cooling gallery adjacent the upper flange. The undulating cooling gallery generally defines a single coolant flow path extending about a perimeter of the cylindrical body. | 08-19-2010 |
| 20100300282 | CONNECTING ROD BORE - 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. | 12-02-2010 |
| 20100300397 | CONNECTING ROD LUBRICATION RECESS - A connecting rod and methods of making a rod are disclosed. A method of making a connecting rod may include the step of providing a connecting rod blank, where the connecting rod blank includes a crankshaft end and a piston pin end. The method may further include forming a crankshaft pin recess in the crankshaft end of the connecting rod blank and a piston pin recess in the piston pin end, and forming at least one lubrication recess in the piston pin end of the connecting rod blank. The lubrication recess and the piston pin recess may both formed concurrently. | 12-02-2010 |
| 20110162614 | PROFILED CONNECTING ROD BORE WITH MICRO-DIMPLES - 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. | 07-07-2011 |
