The article describes the results of simulations of the approved variations of sliding surfaces of ring seals in relation
to a reference symmetrical barrel profile which is most often used in piston internal combustion engines. In particular
the paper discusses the impact of the five assumed variants of sliding profiles of ring seals onto the thickness of oil film
left on the cylinder face by a bottom and upper ring seal, the distribution of internal friction force in oil film between the
ring seal set and the cylinder face, finally the oil film cover on a sliding surface of the upper ring seal. The results presented in the article show a close relationship between the sliding surface profile of ring seals and a unit oil consumption. A relationship between these parameters for the elements lying in the movement plane of a wrist pin axis was proven, as well as for the one lying in the plane perpendicular to it. Exemplary parameters of oil film and friction losses were presented while assuming a constant total axial values of the height and depth of circumferential grooves. The shapes of these grooves on the sliding surface of the ring seals in free state can be made with electroerosion microprocessing or ablative laser microprocessing.
