Abstract

A fluid cooled cylinder liner for mounting in a cylinder of an internal combustion engine is provided. The fluid cooled cylinder liner includes a collar and a seal element. The collar has an outer circumferential surface dimensioned with respect to the inner circumference of the cylinder so as to be in substantially fluid sealing contact therewith, an annular cooling fluid channel formed radially inwardly of the outer circumferential surface, and a radial bore extending radially from the fluid channel through the outer circumferential surface and having one end communicated with the fluid channel and an opposite end communicated with a branch bore of the crankcase of the engine. The seal element substantially seals the interface between the branch bore of the crankcase and the radial bore of the collar of the cylinder liner against the leakage of cooling fluid.
