Abstract

See full text

A cylinder liner includes: a small diameter portion configured to form a cooling water passage between the small diameter portion and an inner peripheral surface of the cylinder block; a large diameter portion disposed adjacent to the small diameter portion in the axial direction and formed to have a larger diameter than the small diameter portion; and at least one seal groove formed on an outer peripheral surface of the large diameter portion in an annular shape along a circumferential direction. The large diameter portion includes a one-side wall portion formed between the cooling water passage and a cooling-water-passage-side seal groove which is a seal groove disposed closest to the cooling water passage in the axial direction, and an other-side wall portion disposed farther from the cooling water passage than the cooling-water-passage-side seal groove is in the axial direction. The one-side wall portion is configured to have, in at least part in a circumferential direction including a thrust direction of the piston, a larger distance to the inner peripheral surface of the cylinder block than a distance from the other-side wall portion to the inner peripheral surface of the cylinder block.
