Friction losses in engine of automobile are very high because its cylinder sizes are small, area of sliding surface is comparatively large and it is used frequently in low output.<br/> Therefore, In order to analysis the characteristics of elasto-hydrodynamic lubrication between the piston ring and the cylinder of the actual engine, The numerical analysis of EHL was studied.<br/> As the numerical analysis method, we used the Newton-Raphson Method of which convergence is very good for a highly loaded contact of EHL.<br/>
