Functionnal optimization of production by honing engine cylinder liner

Functionnal optimization of production by honing engine cylinder liner. Nowadays, the improvement of the combustion engines efficiency in the automotive field is the main key towards the reduction of greenhouse gas emission. The improvement demanded with lower productive cost can be either in the method of manufacturing of crankcase cylinder liner. However, the performance quantification of these processes, especially the honing process, is tightly related to a visual control with some empirical roughness criteria. The purpose of this study is to probe an objective methodology for the characterization of honed surfaces based on multi-scale analysis of the surface. Sensible surface texture characteristics were derived and were used to investigate the influence of the abrasive stones and the expansion velocity in honing. Based on a series of instrumented honing tests, the method shows its powerful ability to detect objective correlations between the honing process parameters and the quality of honed surfaces.
