Influence of Lubricants in Plain Bearing Performance Part I: Evaluation of Bronze and Babbitted Bearing Performance with Base Oil

摘要

From the viewpoint of energy saving, the improvement of fuel efficiency has been required for engine oil. Lowering engine oil viscosity for automotive engines has increased fuel efficiency, which has raised the importance of securing the reliability of plain bearings that are multiused for hydrodynamic lubrication in engines. On the other hand, the regulation of Pb in bearing materials has begun with the goal of preventing heavy metal pollution when automobiles are scrapped. It is therefore necessary to develop engine oil formulation considering bearing materials.
