Cavitation shapes measurements in piston-ring lubrication and their link to lubricant properties

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 ...

Cavitation induced starvation for piston-ring/liner tribological conjunction

The study investigates the mechanism of ring-liner lubrication in the vicinity of the top and bottom dead centres of an internal combustion engine. Predicting lubricant transient behaviour is critical when the inlet reversal leads to thin films and inherent metal-to-metal interaction. It was found that the cavitation, which is located at the trailing edge of the contact before reversal, briefly...

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

Piston Ring Friction Analysis from Oil Film Thickness Measurements by

The oil film behavior of a series of fifteen lubricating oils was tested in a single cylinder spark ignition engine. The oil film thickness between the piston and cylinder liner of this engine was observed using the Laser Induced Fluorescence (LIF) technique. The data was examined for correlations between physical properties of the oil and characteristics of the oil film. The region of the oil ...
