Abstract
A cylinder liner that is casted in a block and defines a cylinder bore corresponding to one cylinder includes: a cylindrical liner body; a projection part provided so as to include a plurality of projections on an outer peripheral surface of a part of the liner body; and a bore adjacent part formed such that the outer peripheral surface at an upper side end of the liner body is positioned more on an inner side of the liner body than the outer peripheral surface below the upper side end, and the projections are absent on at least a part of the outer peripheral surface at the upper side end, in a predetermined range of the outer peripheral surface of the liner body, which faces another cylinder bore to be adjacent when casted in the block.
