<p>A combustion engine has a cylinder liner with a top boss (3) which is an interference fit in the block (5), and a midstop flange (6). The outer portion of the liner between the top boss (3) and the midstop flange (6) forms a wall of a coolant passage (10). A cylindrical inner portion (15) of the liner is at least 30% of the length of the liner, and has a groove (27) in the outer surface thereof adjacent to its bottom end. In the groove is a support ring (18) which swells up under the influence of engine oil to contact a radial support section for the bottom end of the cylinder liner. <IMAGE></p> |
