Document Type and Number:
WIPO Patent Application WO/2019/225039
Kind Code:
A1
Abstract:
This invention addresses the problem of providing a cylinder liner for a cast-covering, with which bonding strength between a cylinder liner and a cylinder block can be improved by minimizing a gap formed in the cylinder block. This problem is solved by a cylinder liner for a cast-covering having a plurality of protuberances in the outer peripheral surface, wherein the following stipulations (i) and (ii) are satisfied. (i) The number of protuberances is five to fifty (inclusive) per 1 cm2 on the outer peripheral surface. (ii) When two lines measuring 15.2 mm × 0.03 mm are set in parallel 3.8 mm apart at any positions on the outer peripheral surface of the cylinder liner, the total number of protuberances in contact with the two lines is eight or fewer.
