A Novel Approach to Reduction of Frictional Losses in a Heavy-Duty Diesel Engine by Reducing the Hydrodynamic Frictional Losses

Example of form removal on a textured surface by removal of the significant texture prior to form removal and the consecutive adding of segmented features. (a) Original surface measurement. (b) Surface form removal by second-order polynomial extraction; it should here be noticed that this surface does not have a flat plateau area; much of the surface form remains after the first form removal step. (c) Grain analysis of textures in which texture elements are extracted. (d) Surface after second-order polynomial form removal based on grain analysis. It should here be noticed that the plateau part of the final surface does not have any residual form.
