  "textContent": "The present invention pertains to a cylinder liner for a cylinder of a combustion engine and a method for producing a cylinder liner as well as a combustion engine comprising at least one cylinder with a corresponding cylinder liner, in particular to improve stiffness and fatigue strength of the cylinder liner and/or to reduce pressure differences between a combustion chamber and an upper part of a piston. Accordingly, a cylinder liner (10) for a cylinder of a combustion engine is suggested, which comprises a longitudinally extending wall, wherein an inner diameter of the wall defines a bore (12) configured for receiving a piston and wherein the wall defines a protrusion (14) extending into the bore (12) and beyond the wall in a radially inward direction. An upper wall portion (16) directly adjacent to the protrusion (14) and extending to a combustion region end portion of the cylinder liner (10) comprises an inner diameter (18) that is larger than an inner diameter (22) of a bottom wall portion (20) directly adjacent to the protrusion (14) and extending to an opposing end portion of the cylinder liner (10).",
