Abstract
An oil cooled cylinder liner, a method for cooling the same, and an opposed piston engine using the oil cooled cylinder liner are described. The cylinder liner includes a liner wall that has an inner face adjacent a piston bore and an outer face including an oil gallery surface. A plurality of grooves are disposed along the oil gallery surface. The grooves run parallel to each other and are spaced apart by bridging portions of the liner wall. At least some of the grooves have at least one fin disposed therein that runs parallel with the grooves. The grooves in combination with the fins increase surface area of the oil gallery to improve heat transfer from the liner wall to oil disposed along the oil gallery surface.
