Abstract

An arrangement may include one of a cylinder liner or a cylinder bore formed in a crankcase of an internal combustion engine, a piston having a peripheral top land and being accommodated in the cylinder liner or cylinder bore, and an annular insert accommodated in the cylinder liner or cylinder bore and extending axially parallel to the piston top land. The cylinder liner or cylinder bore may have a radially inwardly-directed shoulder at an upper free end of the cylinder liner or cylinder bore. The annular insert may have along an upper peripheral free edge of the annular insert, distributed around a circumference of the annular insert, at least two beads or embossments located opposite one another and resting on the radially inwardly-directed shoulder.
