IMechE Automobile Division, Tyne Tees Centre

Warmly invites you to attend our Apr 2018 event



New fuel-efficient engine oils are often formulated with advanced additives and low viscosity base oils. Understanding the lubrication performance at key engine components such as the cam and follower in valve train systems becomes critically important to ensure engine durability with the new fuel-efficient low viscosity oils.

Dr. Ning Ren is the Director of Strategic Research at Valvoline Inc. He has a Ph.D. in Mechanical Engineering from Northwestern University, USA. He is a tribology expert with extensive experience in academic and industrial research, software development and tribological testing. Currently, he focuses primarily on the computational modeling and simulation of tribological systems in automobiles. He also serves as an Associate Editor of Journal of Tribology.




Brief description

Environmental regulation and high fuel cost are among the leading driving forces behind the demand of energy efficient vehicles. Together with new engine hardware technologies, engine oil is expected to significantly contribute to improving vehicle fuel economy. A full numerical mixed lubrication analysis of the cam and roller follower pair in both heavy duty diesel and light duty gasoline engines is conducted using the three dimensional line contact mixed elastohydrodynamic lubrication (EHL) model. The results show significant effects of surface roughness, topography, slide-to-roll ratio, and viscosity grade on lubricant film, contact pressure, and subsurface stress.
