Abstract
A system is provided for an internal combustion engine including at least two cylinders, wherein the at least two cylinders form at least two groups, wherein each group has at least one cylinder, the at least one cylinder of at least one group being formed as a cylinder which can be activated in a load-dependent manner and which is deactivated if a predefined load is undershot. The at least two groups are characterized by different cylinder volumes, the at least one cylinder of a first group having a lesser cylinder volume and the at least one cylinder of a second group having a greater cylinder volume and configured as an activatable cylinder.
