Elastohydrodynamic lubrication of a journal bearing has been usually calculated with bearing deformation. In this study, crank-pin deformation is included in addition to the bearing deformation of con-rod big-end. The calculated results are shown with and without the crank-pin deformation and the effects of the crank-pin deformation on calculated results are discussed. The effects of the crank-pin deformation appear after compression TDC during low speed operation and near suction TDC during high speed operation.
