A CYLINDER LINER FOR A WATER-COOLED INTERNAL COMBUSTION ENGINE

摘要

A cylinder liner (1, 1') for a water-cooled combustion engine has a plurality of cooling channels designed as elongated blind bores (8, 8') extending upwards from a coolant supply chamber (6; 6') and communicating with a coolant outlet chamber (7; 7'). A guide member (21; 38) is mounted within the channel. The guide member prevents the water flow from contacting and thus cooling a section (32; 40) of the channel surface facing towards the combustion chamber so that the temperature gradient over the liner decreases which leads to a lower cooling effect.
