The Elrod's cavitation algorithm was modified to include the effect of density in full film zone and applied to the mass conserving elastohydrodynamic lubrication, EHL, theory of a con-rod big-end bearing. After that, the calculation method of mass conserving EHL with a simple model of an oil passage was proposed. The mass conserving EHL theories with and without oil passage are compared to discuss the feature of the lubrication characteristics and oil flow rate under the dynamic load of an engine.
