Lubrication conditions have significant influences on the formation of tribofilms and then
affect tribological behavior. In this work, the influence of tribofilm formation on the tribological …

Mechanical losses consume about 40% of the total energy developed by a typical
automotive engine. The piston–cylinder system accounts for 50% of the engine frictional …

Using a reciprocating rig to simulate the piston ring-cylinder liner contact, we show that
macro-scale surface texture yields friction reductions in the hydrodynamic regime of up to …

Surface texturing is playing a vital role in reduction of friction and wear of sliding
components in an engine. The dimple shape, dimple size and area ratio are important …

Specific surface textures may reduce the friction and increase the lifting forces in lubricated
contacts. For the detrimental operating condition of mixed friction, wear is induced by the …

Abstract Direct Laser Writing (DLW) using ultrashort pulsed lasers and galvanometer
scanning, has become an established process for surface texturing, allowing an extensive …

The objective of the present investigation is to analyze the tribological performance between
the union of the cylinder liner and the compression ring under the influence of surface …

This work presents the oil film near a single surface texture in an optically accessible sliding
contact reproducing the piston-ring/cylinder-liner contact in an engine. A micropore–a …

This research aims to evaluate the effect of surface texturing on the cylinder liner on
tribological characteristics such as minimum oil film thickness, power losses, and dynamic …

It was utilized to study the micro-textured piston ring-cylinder liner interface tribological
behavior at a constant speed, mimicking the mid-stroke state of an internal combustion …
