Document Type and Number:
WIPO Patent Application WO/2023/189457
Kind Code:
A1
Abstract:
The present invention makes it possible to improve recyclability, achieve a reduction in weight, and improve environmental friendliness. To this end, a cylinder liner (30) according to the present disclosure is provided only to a part of a region of an inner surface (21i) of a cylinder (21) in a reciprocating engine, said region being where a piston ring (50) fitted to a piston (40) that reciprocates in the cylinder (21) slides. The total length L of the liner along the axial direction of the cylinder (21) is less than the inner diameter B of the cylinder. One lower end part (30d), which is toward the bottom dead center side of the piston ring (50) in the axial direction, has protrusions and recesses formed therein.
