A Comprehensive Model to Study the Dynamic Motion of Piston and Friction and Lubrication in I.C.Enignes 2008-28-0061

The Piston assembly friction loss contributes for larger part in the engine frictional loss. In order to reduce the frictional loss due to piston assembly motion, a complete model describing the dynamics of assembly is necessary. This paper presents a model to study the primary and secondary motion of piston and also a model for determination of frictional losses in the piston assembly of an automotive Internal Combustion Engine. A mixed lubrication model based on a two-dimensional Reynolds equation is presented to use in conjunction with a piston secondary motion analysis.
