A Study on Friction Loss of Engine Bearings Focusing on the Viscosity-Pressure Characteristic of the Lubricant and the Stiffness of the Housing
Published July 18, 1995 by Society of Automotive Engineers of Japan in Japan
The effect of the deformation of connecting rod and the piezoviscosity of the lubricant on the performance of bearing are studied in a high speed loading condition of an actual engine, using an elastohydrodynamic lubrication (EHL) analysis. As the result, it was confirmed that the EHL analysis is important for investigating piezoviscous effect on friction loss in such condition. And it was found that, in such heavy load condition, the stiffness of the housing affects the friction loss because of the piezoviscosity, and the piezoviscosity is important for bearing performance as well as the viscosity.
