Cross Hatch Liner Grooves

Abstract

Cylinder liners with the external circumferential surface including a cross hatch machining pattern. Cylinder liners are cast into place as components of an engine block. The liners are positioned into place within the mold of the engine block. Molten aluminum is poured into the mold and surrounds the cylinder liners, and creates the engine block. Because of several process factors, the bond interface between the cylinder liner and engine block is sometimes inconsistent. The inconsistent bond interface between the cylinder liner and engine block may lead to premature engine failure. The cross hatch machining pattern present on the surface of the liner greatly enhances the liquid metal flow around the liner during the casting process. The enhanced molten metal flow around the liner during the casting process improves the bond interface integrity and strength between the cylinder liner and engine block.
