Abstract

The invention relates to a cylinder bore and a method. The cylinder bore is configured to receive a piston for reciprocating movement therein and has a pressure side and a counter-pressure side. The cylinder bore includes a bore surface having a first roughness value in a first longitudinal region on the pressure side and a second roughness value different from the first roughness value in the first longitudinal region on the counter-pressure side.
