摘要： To provide a combination oil ring capable of reducing an oil consumption in a high-speed region even if an oil ring tension is reduced.
In a combination oil ring, a tip end part of an outer peripheral surface in an arbitrary longitudinal section of a segment is in an asymmetrical shape, when a line passing through a center of a segment width is a first intermediate line, a length of a line segment between a position on an engine combustion chamber side and a position on a side distant from the engine combustion chamber on a contour curve at a position at a distance of 3 µm from an outer peripheral vertex toward an inner peripheral side in a segment radial direction is L, and an intermediate line of the line segment L is a second intermediate line, the second intermediate line is located on the side more distant from the engine combustion chamber than the first intermediate line, and the outer periphery vertex of the segment is located on the second intermediate line or on the side more distant from the engine combustion chamber than the second intermediate line, and the pair of segments are installed in the oil ring groove so that the respective outer periphery vertexes are located on the side distant from the engine combustion chamber.
