Effect of Design Parameters on the Reduction of Top Piston Ring Friction

Abstract:

In order to reduce ring-liner interface friction power loss, this paper focuses on the structure parameters of the top ring, and investigates how the value of those parameters will influence top ring-liner friction power loss and the minimum thickness of oil film at top ring-liner interface. A mixed lubrication model is developed to simulate the effect of varying design parameters on ring-liner friction. Case study shows that ring-liner friction power loss will be reduced with decreased axial ring height and barrel height. This study provides a theoretical basis for design the top ring with reduced friction power loss at ring-liner interface.
