ABSTRACT:
A cylinder liner for a large size internal combustion engine has a neck which extends between the cylinder block and the head to define a combustion chamber in each cylinder. The liner has internal cooling ducts which are formed by blind holes in the neck of the liner which communicate with entry and exit passages for liquid coolant at parts of the liner within the cylinder block, leaving the exposed neck portion free of through holes where high strength is required. Each blind hole is subdivided by an internal baffle into flow and return passages for coolant.
