| description | To provide a cylinder liner which can be improved in terms of recycle performance, can be materialized in further size reduction, therefore can be improved in environmental performance, and a reciprocating engine having the cylinder liner.SOLUTION: A cylinder liner 30 is provided which is arranged in a reciprocating engine, the cylinder liner 30 is arranged in only a part of a region in which a piston ring 50 mounted to a piston 40 reciprocating in a cylinder 21 slides, out of an inner face 21i of the cylinder 21 of the reciprocating engine, a liner total length L of the cylinder 21 along an axial direction is shorter than an inside diameter B of the cylinder, and irregularities 32 are formed at one lower end part 30d being an end part shifted to a bottom dead center side of a piston ring 50 in an axial direction.SELECTED DRAWING: Figure 2
【課題】リサイクル性能の面で改善することができ、かつ更なる軽量化を達成することができ、もって環境性能を向上させることができるシリンダライナおよびシリンダライナを備えた往復動機構を提供する。【解決手段】往復動機関に設けられるシリンダライナであって、当該シリンダライナ３０は、往復動機関におけるシリンダ２１の内面２１ｉのうち、該シリンダ２１内を往復動するピストン４０に装着されたピストンリング５０が摺動する領域の一部にのみ設けられ、シリンダ２１の軸方向に沿ったライナ全長Ｌがシリンダの内径Ｂよりも小さく、軸方向においてピストンリング５０の下死点側寄りの端部である一方の下端部３０ｄに凹凸３２が形成された構造である。【選択図】図２ |
