Abstract:
1. A masking system for the masking of a crank chamber of an internal combustion engine during a surface treatment of a cylinder running surface of a cylinder bore of a first cylinder of the internal combustion engine, including a hollow masking body with a connector segment for the connection of the hollow masking body to the cylinder bore as well as with a screen segment, the hollow masking body is being configured such that the connector segment of the hollow masking body can be positioned at the cylinder bore of the first cylinder at the crank chamber side during the surface treatment of the first cylinder of the internal combustion engine, and a masking element for masking a second cylinder bore during the thermal coating process, the masking element being able to be positioned in the cylinder bore of the second cylinder during the thermal coating process of the first cylinder for the covering of the cylinder running surface of the second cylinder, the masking element being configured such that a flow gap of presettable width can be set for the generation of a flow of a fluid between the masking element and the cylinder running surface of the second cylinder.
