Abstract:
A fluid cooled cylinder liner for mounting in a cylinder of an internal combustion engine having a crankcase which includes a longitudinal bore and a branch bore extending transverse to the longitudinal bore having one end communicated with the longitudinal bore and an opposite end communicated with the cylinder, the fluid cooled cylinder liner comprising:a collar having an outer circumferential surface dimensioned with respect to the inner circumference of the cylinder so as to be in substantially flush 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 the branch bore in the mounted position of the cylinder liner in the cylinder; and a seal element for substantially sealing 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, whereby cooling fluid circulates in a substantially sealed manner in a circuit formed by the longitudinal bore and the branch bore of the crankcase and the radial bore and the annular fluid channel of the cylinder liner.
