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.
摘要翻译： 本发明的具体实施例提供了新的流体冷却气缸套。 优选的衬垫是环形圆筒，其包含大致平行于圆柱体的轴线布置并且整合在气缸的内表面和外表面之间的多个通道。 优选地，整体通道被布置成使得它们通常比内表面更靠近衬垫的外表面。 每个通道至少有两个开口。 在气缸的相对端上具有两个开口的通道延伸衬套的整个长度，而具有在衬套的一端具有开口的通道和沿着衬垫的表面的第二开口仅延伸到衬套长度的一部分 。 在优选实施例中，衬套的外表面上的开口将被布置成位于垂直于气缸的轴线并且在气缸的任一端附近的平面中的圆圈; 确保每个通道穿过衬套的大部分长度。 优选地，气缸套包括选自铝，具有颗粒增强材料的铝基金属基复合材料（MMC），超合金，陶瓷基复合材料（CMC）和碳石墨泡沫材料中的至少一种材料。 优选地，衬垫包括加热元件。
