TL;DR: The experimental results have shown that the proposed approach is effective to generate cylinder liner surface that would simultaneously meet the explicit surface topographic specifications currently practiced by the industry.

TL;DR: In this article, a theoretical piston ring/cylinder wall model has been utilized to study the dependence of the oil film thickness on surface roughness shape and amplitude, as well as on engine operating conditions.
Abstract: In this investigation, a theoretical piston ring/cylinder wall model has been utilized to study the dependence of the oil film thickness on surface roughness shape and amplitude, as well as on engine operating conditions. For a given roughness, a plateau honed cylinder wall surface was found to produce a thinner oil film. It has also been shown that the small crosshatch angle used when honing the cylinder wall produces surfaces that enhance hydrodynamic action.

TL;DR: In this article, the influence of different parameters of the rough honing process on surface roughness and material removal rate were studied by means of regression analysis, and the results showed that roughness depends mainly on grain size, pressure and density of abrasive.
Abstract: In the present work influence of different parameters of the rough honing process on surface roughness and material removal rate were studied. Specifically, second order mathematical models are presented for mean average roughness Ra (μm), maximum peak-to-valley roughness Rt (μm) and material removal rate Qm (cm min −1 ), obtained by means of regression analysis. For doing this a central composite design was defined, with a full two-level five variables design of experiments, 5 centre points and 10 face-centred points. Steel cylinders were employed. Abrasive chosen was cubic boron nitride. Considered factors were grain size, density of abrasive, tangential speed of cylinders, linear speed of honing head and pressure of abrasive stones on internal surface of cylinders. From the models most influential factors on process quality as well as on productivity were determined. Within the range studied, roughness depends mainly on grain size, pressure and density of abrasive. Material removal rate depends on grain size and pressure, followed by tangential speed. Optimization by means of the desirability function technique allowed determining most appropriate conditions to minimize roughness (surface quality) and/or maximize material removal rate (productivity).

TL;DR: In this article, the authors used multiscale surface analysis to study the progress of abrasive wear mechanisms which occurred in cylinder liners while they were being honed, which is an important part of quality assessment in cylinder liner production.
