Abstract

See full text

A method is provided for coating a cylinder of an internal combustion engine. The cylinder (1) has a cylinder lining surface section (4) with a piston running surface (5) that faces an interior space (3) of the cylinder (1) and along which a piston of the internal combustion engine (2) can be moved. The cylinder (1) also has at least one further surface (13, 14) that adjoins the interior space (3). The further surface (13, 14) may be a bearing section surface (13) for mounting a crankshaft of the internal combustion engine (2), and a run-out section surface (14) between the bearing section (6) and the cylinder lining surface section (4). The method includes forming a defined structure on the further surface (13; 14) and then spraying a coating on the piston running surface (5).
