Abstract
Systems and methods are provided for a cylinder liner for an engine including a catcher feature on a side surface to provide radial support and improved coolant sealing. In one example, the catcher feature may include a continuous stepped catcher extending from the cylinder liner body and a stepped tab of the engine block, the stepped catcher resting on the stepped tab. Also, a radial flange in the upper portion of the cylinder liner may be coupled to the engine block, the coupling sealed via an O-ring nestled in a groove formed in the radial flange.
