Abstract
A process for selecting a piston ring for a piston containing internal combustion engine such that the engine experiences a reduction in lubrication oil consumption (LOC) used therein. The process can include providing engine specifications for an engine for which the piston ring is to be selected and simulating engine temperatures for the engine as a function of the engine specifications. The process can also include simulating bore distortion for the engine as a function of the simulated engine temperatures and simulating piston ring dynamics for the engine as a function of the simulated bore distortion. Once the simulated piston ring dynamics have been obtained, the process can include calculating a plurality of LOC values and selecting a piston ring as a function of the calculated LOC values.
