Water-cooled reciprocating piston internal combustion engine

摘要

A water-cooled reciprocating piston internal combustion engine has a crank casing or the like, interchangeable cylinder liners and a cylinder head which can be removed from the crank casing or the like. At the same time each cylinder liner has its own cylinder base integrally formed with the cylinder head. In order to be able to equip such an internal combustion engine with suspended valves without experiencing difficulties in the machining, particularly the finishing of the valve seat rings, valve seat rings are provided which pass through the cylinder bases of the cylinder liners and are fixed in the cylinder head and can be removed with this from the cylinder liners.
