The main directions of changes in new internal combustion engine designs are determined not only by legislation on the toxic components emission in the exhaust gases, but also by the changes resulting from technological development, which are the results of research and development activities. One of the basic systems that has undergone intensive development recently is the piston-rings-cylinder (PRC) node. This article contains an original analysis of the direction of changes in cylinder surface shaping in terms of the cylinder’s main functional features in the PRC system (the casting material and the opening surface topography after the finishing process). The results of the research on cast iron materials for cylinder liner castings with strength of Rm > 300 MPa were analyzed based on the centrifugal casting method and their finishing stage in the finishing process meeting the criteria for reduction of oil consumption and particle emissions for new HDD type engine designs. The author also points to innovations in surface structure metrology based on new 3D optical measurement methods and the quality rating method by Mercedes company.
