On a correctly designed engine piston-cylinder assembly the contact of ring and bore should take place through a layer of oil, called oil film. In order to obtain a continuous oil film a proper lubricating oil should be introduced into the region of node elements collaboration, sliding surfaces should have adequate geometry and parameters of collaboration should be chosen suitably. The ring pressure against the liner is one of important quantities that affect formation of oil film. Selection of ring pressure circumferential distribution is pretty complex and depends on a number of factors and changes along the engine life. Presented paper discuss the methods of ring pressure distribution along its circumference and indicate problems connected with measurements. Moreover, basic assumptions used for construction of compression ring mathematical model as well as results obtained using that model were presented for full and partial loads. A need for the construction of computational program that could take into consideration evenly worn and distorted bore surface have been validated as well.
