ABSTRACT:
The invention relates to a cylinder crankcase (4) comprising at least one cylinder liner (2) which is integrally cast in the cylinder crankcase (4). The cylinder liner (2) runs in the cylinder crankcase (4) from a cylinder-head side (6) to an oil-chamber side (8) and has an inner side (10) and an outer side (14). The invention is characterized in that the cylinder liner (2), at least at one end, is longer along the inner side (10) in the axial direction (20) than on the outer side (14). The transition from the inner side (10) to the outer side (14) is affected in the form of encircling, concentric steps (22).
