ABSTRACT:
A cylinder lubrication system for a combustion engine. The lubricant is directed to the cylinder wall through a piston moving in the cylinder. The piston comprises a piston pin above which there are a plurality of piston rings sealing a combustion chamber at the top side of the piston. There is a lubrication groove in the outer mantle surface of the piston between the piston pin and at least a majority of the piston rings, preferably all of the piston rings. The lubrication groove is open in a direction outwardly from the piston and has lubricant feed ducts connected thereto from the inside of the piston. In the feed ducts the lubricant is subject to continuous pressure when the engine is continuously running.
