“…Moreover, he suggests that plateau honing pressure on cylinder liner roughness parameters is negligible [8,9]. Different previous studies highlight a strong connection between the topography of honed surfaces and their wear resistance during running-in [1,5,6].…”

AbstractThe texture change during running-in alters the performance and efficiency of a tribo-mechanical system. During mass production of cylinder liners, a final finishing stage known as "plateau honing" is commonly added to reduce the running-in The present paper thus investigates the various aspects of the wear modeling that caused running-in problems in honed surfaces and its implications on ring-pack friction performance. To illustrate this, plateau honing experiments under different conditions were first carried out on an instrumented vertical honing machine. The plateau honing experiments characterize the surface modifications during running-in wear of cast-iron engine bores using advanced characterization method. Based on the experimental evidence, a running-in wear model was developed. Finally, a numerical extension of the developed model was applied to solve the Reynolds equation by taking into account the real surface topographies of the engine bore. This enables us to predict realistic friction performance within the cylinder ring-pack tribosystem.

“…The main objectives in developing this technology were to reduce wear, friction losses, and lube oil consumption while maintaining a productivity comparable with that of conventional plateau honing and achieving a high degree of reliability of the process itself and in mass production conditions, a long tool life, minimum deformation in the honed surfaces, i.e., minimal dislocations in the boundary layer, and the creation of a uniform and consistent surface over the whole cylinder bore. The scuffing resistance may be achieved by altering the geometry of basic honing valleys [17]. The finest material ratio parameters of the cylinder liner surface in terms of oil consumption and the emission of harmful exhaust compounds have been estimated for both cast iron liners [18] and liners made of aluminum alloys [19].…”

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)

In this study, it is aimed to experimentally optimize the interior honing process, which is applied to improve surface roughness of the internal cylinder surfaces of the hydraulic cylinders in a privately owned company. The hydraulic cylinders produced in the company are used in heavy construction machineries. In the application, the optimal values of the critical honing parameters are determined by applying two different experimental design approaches namely, Taguchi and response surface methodologies separately and compared. For interior honing process, linear speed of the honing head, tangential speed of the cylinders and abrasive grain size are considered as critical parameters in the minimization of the surface roughness in the study. Experimental results are provided to illustrate the effectiveness of the application.
