Method for processing housing wall of crankcase in region between adjacent cylinder spaces for producing ventilation opening, involves machining recessed area from side of housing wall for recessing area to produce ventilation opening

摘要

The method involves producing a recessed area (13) on a side of a housing wall (3). The recessed area is aligned perpendicular to a longitudinal extension of cylinder spaces (1). A coating is applied on the housing wall for generating a cylinder bore (5). The recessed area in the housing wall is machined from a side of the housing wall for recessing the recessed area to produce a ventilation opening. The recessed area in the housing wall is machined from the side of the housing wall for producing another recessed area without producing the opening in the housing wall.
