A Dynamic Theory of Piston-Ring Lubrication : 2nd Report, Experiment

Conservative one-dimensional finite volume discretization of a new cavitation model for piston–ring lubrication

This paper presents a conservative numerical implementation of a new cavitation model that is well suited for lubrication problems with cavitated regions in which the fluid film is attached to just one of the participating surfaces, as happens for instance in piston–ring assemblies. This new model was recently proposed by Buscaglia et al. (2011) and is the first successful attempt at modifying ...

Comparison of Mathematical and Experimental Simulation of Lubrication Conditions in the System Of Piston, Piston Ring and Liner

Three-Dimensional Model of Lubrication and Dynamics for The Piston Ring-Pack in Internal Combustion Engines

Effects of Surface Irregularities on Piston Ring- Cylinder Tribo Pair of a Two Stroke Motor Engine in Hydrodynamic Lubrication

Tribological parameters such as friction, lubrication and wear influence strongly the engine component's life. In this study, a piston ring-cylinder system simulated taking into account the surface modifications under fully flooded lubrication and normal engine conditions. The hydrodynamic pressure field solved based on the Navier Stokes equations by Fluid Structure Interaction analysis. A real...

An Improved Lubrication Model between Piston Rings and Cylinder Liners with Consideration of Liner Dynamic Deformations

The friction pair of piston rings and cylinder liner is one of the most important friction couplings in an internal combustion engine. It influences engine efficiency and service life. Under the excitation of piston slaps, the dynamic deformation of cylinder liner is close to the surface roughness magnitudes, which can affect the friction and lubrication performance between the piston rings and...
