エンジンのシリンダライナ。 A cylinder liner is a cylinder liner in which a metal cylinder body is shrink-fitted around a cylinder liner body made of ceramics, and when the cylinder liner is press-fitted into the cylinder block of an engine, the cylinder liner body is attached to the oil ring of the piston at the bottom dead center. The metal cylindrical body extends above the oil ring position of the piston at the bottom dead center, and forms a cylinder liner lower body, and the cylinder liner body and the cylinder liner lower body A concave portion extending in an annular shape is provided on the cylinder bore side between the body and the concave portion.
A cylinder liner for an engine, characterized in that a ring is disposed so as to protrude toward a cylinder bore side beyond an inner wall surface of the cylinder liner main body and an inner wall surface of the cylinder liner lower body.
