“…No bore polishing areas were observed. Michalski and Woś [37] present a more detailed report on the characteristics of wear shown by the whole P-C device. Although the measured wear turned out to be rather high, the engine parameters dropped moderately.…”

“…The rough engine performance results were reduced to normal conditions, i.e., an atmospheric pressure of 760 Torr and an ambient temperature of 15°C. All tested engines were disassembled in order to be able to measure P-C device wear for detailed analysis of wear processes [37]. Similarly to the after-machining analysis, the same 2D contact instrumentation and procedures were used.…”

Reciprocating piston engines are the major propulsion devices for light aircrafts, helicopters, and essentially all automotive vehicles. They are expected to fulfil both present-day and future demands for engine performance, durability, fuel economy, and exhaust emissions legislation. One of the key factors related to these demands is the need to the limit thermomechanical internal losses, wear, and lubricating oil consumption, which are in turn conditioned by the tribological behavior of the piston-cylinder assembly. Consequently, this latter system requires a multi-directional approach in terms of manufacturing. Apart from various modifying techniques (e.g. laser texturing), a conventional plateau-honing operation is still the standard technology for shaping cylinder liner surface microstructure. This paper describes the distinctions between variations in the performance of the engines in relation to cylinder liner roughness parameters due to different honing settings. Five air-cooled reciprocating aircraft engines (FRANKLIN 4A-235-B31) served as the objects of research. The engines passed durability tests on the dynamometer bed, including operation under artificially intensified wear conditions. The results show a significant impact of the brand-new honed cylinder liner surface microstructure on the engine output parameters. Detailed study proves that some of the cylinder liner roughness parameters, specifically, the slope of the root mean square line (RMS) for valley roughness Rvq and the linear triangle area for valleys A2, are strongly correlated with the engine operational properties. Higher values of Rvq and A2 are associated with an improvement in engine performance but result in a deterioration in the exhaust harmful emission.Keywords Gasoline internal combustion engine Á Engine performance Á Plateau honing Á Piston-cylinder assembly Á Cylinder liner Á Surface roughness Á Abrasive wear Á Tribological behavior Abbreviations A2Roughness profile parameter-linear triangle area for valleys (lm) CO Concentration of carbon monoxide in exhaust (%) HC Concentration of hydrocarbons in exhaust (ppm) ge Brake-specific fuel consumption (BSFC; g/kW h) Ne Engine output power (kW) Mo Engine output torque (N m) go Engine total efficiency (%) P-C Piston-cylinder Rq Roughness profile parameter-root mean square of heights (lm) Rvq Roughness profile parameter-slope of a linear regression of valley region (lm)

“…The running surface of the sliding strip has a parabolic profile in the direction of sliding to simulate the barrel-shape profile of a piston compression ring. The flat test specimen and sliding strip were machined to represent surface topography in line with typical roughness parameters found in ring and liner surfaces [43]. However, no cross-hatching is carried out on the test specimen, which is usually used on liner surface.…”

A systematic approach is required in order to determine the frictional characteristics of a contacting pair in the presence of a tribofilm. Despite the clear benefits in functionality and in reducing wear, the generation of ZDDP-based tribofilms often lead to increased frictional losses. Such an increase is also observed in the tribometric tests reported here, as well as in open literature. This paper investigates the underlying mechanics for the rise in friction using an integrated methodology, based upon Atomic Force Microscopy (AFM) and X-ray Photoelectron Spectroscopy (XPS). The use of an analytical contact mechanics model demonstrates that the pressure coefficient of boundary shear strength, measured using lateral force microscopy, provides an explanation for the observed increase in measured friction at micro-scale.
