摘要: Particular embodiments of the present invention provide novel fluid-cooled cylinder liners. Preferred liners are annular cylinders containing a plurality of passages, arranged generally parallel to the axis of the cylinders, and integrated between the inner and outer surfaces of the cylinders. Preferably, the integral passages are arranged so that they are typically closer to the outer surface of the liner than the inner surface. Each passage has at least two openings. A passage with two openings on opposite end of the cylinder runs the entire length of the liner, while a passage with a opening at one end of the liner and a second opening along a surface of the liner runs only for a fraction of the liner length. In preferred embodiments, openings on the outer surface of the liner will be arranged in a circle lying on a plane perpendicular to the axis of the cylinder, and near either end of the cylinder; ensuring that each passage traverses the majority of the length of the liner. Preferably, the cylinder liners comprise at least one material selected from the group consisting of aluminum, a aluminum-based metal matrix composite (MMC) with a particulate reinforcement, superalloys, ceramic matrix composite (CMC), and carbon graphite foam. Preferably, the liners comprise a heating element.
