an interior portion 62 of piston 10 interior portion 62 is defined by an inner surface 66 during operation of an internal combustion engine piston 10 reciprocates in a cylinder 70 cylinder 70 includes a head 74 and a cylinder wall 78 piston 10 moves toward the head 74 during a compression stroke and compresses fuel and gasses in combustion chamber 16 that were allowed in through an intake valve not shown the fuel and gasses are ignited to begin the power stroke pushing piston 10 away from head 74 as piston 10 moves away from cylinder head 74 oil control ring 26 is supposed to move into abutting contact with an annular wall 82 of annular groove 22 oil control ring 26 then scrapes oil from cylinder wall 78 away from cylinder head 74 in a normal piston the power stroke produces the aforementioned blow by gasses that have a tendency to move down cylinder wall 78 past piston rings 38 where they provide pressure against oil control ring 26 the pressure pushes oil control ring 26 out of abutting relation with annular wall 82 destabilizing ring 26 further the blow by gasses tend to push past oil control ring 26 making it very difficult for oil control ring 26 to keep contact with cylinder wall 78 and scrape oil therefrom consequently.
