Abstract
An anti-polishing ring (4) to be used in a cylinder (1) of a large diesel engine, which is supported to a cylinder liner (2) for the purpose of removing possible carbon deposit and carbon residue from the upper portion of a piston (3). The anti-polishing ring (4) is provided with an arrangement, by means of which the lower edge (4b) of the anti-polishing ring can be pressed in the radial direction of the cylinder inwards towards the mantle surface of the upper portion of the piston so that the proportion between the diameters of the lower edge (4b) and the upper portion (4a) of the anti-polishing ring is at its minimum while the engine is running.
