The lubrication of the piston ring is an important subject for many research activity, because of the interaction at the piston ring-cylinder interface provides substantial influence on the friction, wear, oil consumption and power loss in an internal combustion engine. This paper is a contribution on the analyses of the effect of oil viscosity, pressure drop, piston speed and minimum film thickness on the top ring friction force, taking into account the ring approach motion to the cylinder liner by solving with an approximate model the two-dimensional Reynolds equation.
