状の凹部又は凸部が少なくとも１本以上形成され、同凹
部又は凸部に嵌合するように上記上面壁に対向するシリ
ンダヘッドの下面壁に凸部又は凹部が形成されたことを
特徴とするエンジン構造。In a reciprocating engine in which a piston reciprocates within a cylinder, at least one circumferential recess or protrusion surrounding the cylinder is formed on the upper wall of a substantially cylindrical cylinder liner having a sliding surface in contact with the circumferential wall of the piston. An engine structure characterized in that a convex portion or a concave portion is formed on a lower wall of the cylinder head that faces the upper wall so as to fit into the concave portion or the convex portion.
