    Abstract: PROBLEM TO BE SOLVED: To reduce piston friction and wear characteristics without disadvantaging oil consumption and fuel consumption. SOLUTION: Pockets 24 for retaining lubricant to reduce friction between a cylinder bore wall 16 and a piston 14 is formed to the wall 16 of at least one cylinder bore 10 for slidingly supporting the piston 14. In this case, the pockets 24 are elongate and have axes which are substantially parallel to the axis of the cylinder bore. The pockets 24 are located at a first region (a) supporting the piston 14 when the piston 14 is at its top dead center position. A method of manufacturing the cylinder is also provided.
