摘要：
A system is provided for an internal combustion engine comprising, at least two cylinders wherein the at least two cylinders form at least two groups, wherein each group comprises 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 compression ratios, the at least one cylinder of a first group having a higher compression ratio and the at least one cylinder of a second group having a lower compression ratio and the at least one cylinder of the second group comprises an activatable and deactivatable cylinder. Use of the first cylinder group, and deactivation of the second cylinder group during partial loads increases engine efficiency and fuel economy.
