Abstract
A cylinder liner that is casted in a block and defines a cylinder bore for one cylinder includes: a cylindrical liner body; a projection part including a plurality of projections on an outer peripheral surface of a part of the liner body; and a bore adjacent part inclined at a predetermined angle to an axial direction of the body and extending in the inclination direction, at a predetermined part between an upper side end and a lower side end of the body, of the outer peripheral surface of the body, which faces another cylinder bore to be adjacent when casted in the block. The outer peripheral surface of the bore adjacent part is positioned more on an inner side of the body than the outer peripheral surface above and below, and is formed such that the projections are absent on at least a part of the outer peripheral surface.
