ピースオイルリング。 A three-piece oil ring for internal combustion engines that is attached to the oil ring groove of a piston and consists of upper and lower side rails and a spacer that is located between them and urges the upper and lower side rails toward the cylinder bore.
3 for an internal combustion engine, characterized in that a drop in the radial direction of the oil ring per fixed width in the vertical direction on the sliding surface between the upper side rail and the cylinder bore is smaller than a drop on the sliding surface of the lower side rail.
Peace oil ring.
