Cylinder liners of internal combustion engines must be adequately cooled to obviate oil degradation, carbon packing in the ring area, and piston seizure. The engine includes a block which cooperates with the cylinder liners to define an upper and lower axially spaced coolant chambers. A sleeve is located in a groove defined in the cylinder liner and disposed between the upper and lower coolant chambers. The sleeve and the cylinder liner define a plurality of circumferentially spaced venturi throats. The venturi throats provide a relative long flow path and controls the flow rate of the coolant being communicated from the lower coolant chamber to the upper coolant chamber in order to dissipate heat away from the cylinder liner. |
