Studies of changes in the stress-deformed state of its working surface were carried out to improve the surface layer quality and the operational properties of the internal combustion engine’s cylinder liners. A technique for modeling the operation of the “liner–ring” conjugation using the finite element method is proposed. A calculation scheme has been developed that considers the liner’s main design features and the conditions for its loading by contact loads from the rings and gas pressure. The selected calculation scheme of the part and the boundary conditions of the connection operation made it possible to simulate and calculate the stress-deformed state of the surface layer of the liner’s working surface. The research results are obtained through graphs and stress diagrams of the surface layer of the cast-iron liner working surface along the entire contact zone with piston rings. The presence of stress concentration at the boundaries of the liner contact area with the ring has been established. It was proved that there is a peak of compressive stresses in front of the ring in the contact zone and tensile stresses behind the ring. Applying antifriction coatings to the working surface of the part was proposed to reduce the negative effect of tensile stresses. The obtained research results can be used to improve the technology of processing cylinder liners during their manufacture and restoration to improve the product’s operational properties.
