Abstract
A coolant-shunt-providing cylinder liner of the flanged type is provided with a shunt circuit within the liner for coolant flow through the liner. The shunt circuit includes an array of three annular cooling channels separated from each other by two annular ribs. The width (axial extent) of each channel is substantially less than half the axial extent of the liner's cylinder block engaging portion that is associated with the upper end of the liner. The width (axial extent) of the array of three channels is substantially greater than half the axial extent of the cylinder block engaging portion. Cutouts in the ribs are provided for distributing incoming coolant to the three cooling channels from a main coolant chamber of a cylinder block in which the liner is receivable.
