Squeeze Film Investigations in a Simulating Piston-Ring Cylinder Liner Experimental Set-up

The importance of these investigations lies to the combination of experimental results with cavitation initiation investigations and its development after the dead centers of the stroke as well as rheological behavior of different chemical additives with a view to establishing the likely performance gains in new lubricant formulations. Lubricant formulation plays an important role because at higher temperatures lubricant additives have a different interaction with contacting surfaces and in this manner the resulting effect of asperity contact is either increased or reduced.
