This paper presents a model for the lubrication and friction between a twin land oil control ring and the liner within an engine cycle. This model is based on the deterministic method, which considers micro geometry of the liner finish and its effects on both hydrodynamic lubrication and asperity contact. In this particular application, the liner surface micro features are solely responsible for hydrodynamic pressure generation due to the flat face profile of a typical twin land oil control ring, contrasting to the traditional average model where ring surface macro geometry is most important in generating hydrodynamic pressure.
