摘要： A cylinder liner for being mounted to a cylinder head of an internal combustion engine includes an inner liner face for guiding a piston of the internal combustion engine, an outer liner face, and a liner end face facing the cylinder head in a mounted state and connecting the inner liner face and the outer liner face. The inner liner face extends along a cylinder axis of the cylinder liner. The liner end face includes a sealing groove for holding a joint ring and a step-like structure formed in a liner wall of the cylinder liner. The step-like structure includes in series a first radially extending liner face, a first axially extending liner face, a second radially extending liner face, a second axially extending liner face, a third radially extending liner face, and a transition liner face.
