    Abstract: A cast iron cylinder liner of the present invention includes a plurality of grooves formed on an outer surface of the cylinder liner. Each of the grooves extends in a circumferential direction of the cylinder liner in a ring or spiral shape, and the grooves divide the outer surface of the cylinder liner into a plurality of ring or spiral sections. The outer surfaces of the ring sections have a uniform distance from the central axis of the cylinder liner over the entire area of the outer surfaces, and the grooves being arranged symmetrically with respect to the center of the cylinder liner in an axial direction thereof. Each of the grooves has a J-shaped longitudinal cross-section including a first inclination part and a groove bottom part. The first inclination part extends from the outer surface of one of the ring sections or of one turn of the spiral sections toward the center of the cylinder liner in an axial direction thereof. The groove bottom part has a longitudinal cross-section approximately in the form of a circular arc, and extends from the first inclination part in a direction away from the center of the cylinder liner in an axial direction thereof
