ABSTRACT:
A cylinder liner for a piston in an internal combustion engine with a cylinder block and a cylinder head mounted on the top of the latter. The cylinder liner is removably inserted in a cavity in the cylinder block, which cavity extends from the cylinder block upper surface down to the crankcase. The cylinder liner is axially fixed in the cavity by the cylinder head and by a bearing projection on the cavity wall, on which bearing projection a supporting projection of the cylinder liner bears. The contact area between the bearing projection and the supporting projection is situated in the region of the bottom dead center position of the lower, gas sealing, piston ring in the cylinder liner. The liner is surrounded by at least one coolant passage around the upper portion of the liner, and by a second cooling medium passage for air which is separate from the passage and which extends down to the contact area.
