摘要： A cylinder assembly for use in an internal combustion engine is disclosed, The cylinder assembly may include a cylinder, a piston disposed within the cylinder, a plurality of piston rings encircling the piston, and a cylinder liner fitted around the piston in a cylindrical space in which the piston reciprocates. The piston may reciprocate within the cylinder along a longitudinal direction of the cylinder. The cylinder liner may include an upper section, a middle section, and a lower section. The upper section may be composed of a first texture; the middle section may be composed of a second texture that is rougher than the first texture; and the lower section may be composed of a third texture that is smoother than the first texture and the second texture.

摘要： A compression ring for an engine is disclosed. The compression ring may have a cylindrical body having an outer surface, and a central opening formed within the cylindrical body and concentric with the outer surface of the cylindrical body. The cylindrical body may have a radial dimension from the central opening to the outer surface that is about 1.1 to 1.3 times as long as an axial dimension of the cylindrical body.
