Abstract
An engine cylinder liner includes inner and outer walls formed integral with a head seat rim and defining a coolant jacket for cooling the inner cylinder wall. Stiffening ribs are provided for strengthening the upper liner structure to withstand combustion forces between the liner and a cylinder head attached to the head seat rim. The stiffening ribs are generally triangular and extend from a low point on the outer wall upward and inward to connection with the inner wall adjacent stud bosses in the head seat rim. Thus, connection of the ribs with the inner wall is minimized and the free flow of coolant along the inner wall is maximized, thereby improving cooling of the cylinder wall and reducing wear and scuffing of the liner in service.
