HIGH STRENGTH STEEL CYLINDER LINER FOR DIESEL ENGINE

摘要

A diesel engine is fitted with a thin-walled wet liner fabricated of steel. The liner has a hardness that is within 10-20 Rc of the hardness of the piston rings carried on a piston within the liner. The inner surface of the liner is manufactured with a TRD=5Rvk (100−Mr2) of between 30 and 400 μm, and a compound liner thickness to bore diameter in the range of 1.5 to 4 percent.
