An Overview of Engine Components Friction Modeling

Development of efficient internal combustion engines (ICEs) is receiving wide attention due to increasing environmental legislation limits and fuel and emission costs. In order to improve ICEs performance, it is vital to gain insight of lubrication mechanism and tribological performance of engine reciprocating and rotating components. Analytical modeling of engine components such as piston ring assembly (PRA), connecting rod big eye and main journal bearings tribological behavior widely accepted as reliable tool by researchers and car industries. The principle aim of this paper is to briefly describe technical aspects and governing equations as well as numerical approaches apply to simulate
