Abstract
A cylinder assembly in an internal-combustion engine having a cylinder liner is provided with a reinforcing ring shrunk fitted around the upper end part of the liner and provided with liquid passages communicating with respective recesses grooved in the outer surface of the upper end part of the liner, thereby forming cooling liquid passageways of a cooling system. This construction affords high strength of the cylinder assembly and remarkably effective cooling performance thereof, which make possible the production of engines of extremely high performance.
