ZYLINDEROBERFLÄCHE

摘要

First (5) and second (6) surface areas of a piston's (2) cylinder each have first and second surface roughness respectively. The first surface area includes a contact area that lies between the piston and the cylinder surface and is set towards the piston's top dead center (TDP). The second surface area joins the first surface area towards the piston's bottom dead center (BDP). An Independent claim is also included for a method for producing a cylinder surface.
