Abstract: The processing route of machining the cylinder liners was discussed and the technical difficulties were analyzed, based on the analyses of structural features and application advantages of cylinder liners for 230 series high-power two-stroke diesel engines. The key technologies such as cylinder liner blank casting, brazing of cylinder liner body and water jacket, internal hole laser quenching strengthening treatment and honing of non-circular hole were studied and verified. Based on these studies, the domestic development of the 230 series cylinder liners was successfully realized. The products are put into production in lots and the application effectivenesses are very good.

Key words: cylinder liner casting, brazing, laser harden, non-circular hole, honing
