Exhaust-gas-turbocharged internal combustion engine with partial deactivation

A system, comprising:

• a supercharged internal combustion engine having at least two cylinders arranged into a first group and a second group, each cylinder having at least one outlet opening adjoined by a respective exhaust line for discharging exhaust gases via an exhaust-gas discharge system, each cylinder having at least one inlet opening adjoined by a respective intake line for supply of charge air via an intake system,
• each cylinder of the first group being operational even during partial deactivation of the internal combustion engine, and each cylinder of the second group being a load-dependently switchable cylinder,
• each exhaust line of each cylinder of the first group merging to form a first overall exhaust line, thus forming a first exhaust manifold, and each exhaust line of each cylinder of the second group merging to form a second overall exhaust line, thus forming a second exhaust manifold,
• each intake line of each cylinder of the first group merging to form a first overall intake line, thus forming a first intake manifold, and each intake line of each cylinder of the second group merging to form a second overall intake line, thus forming a second intake manifold;
• a first exhaust-gas turbocharger having a first turbine arranged in the exhaust-gas discharge system and a first compressor arranged in the intake system, the first turbine and the first compressor being arranged in on a first rotatable shaft;
• a second exhaust-gas turbocharger having a second turbine arranged in the exhaust-gas discharge system and a second compressor arranged in the intake system, the second turbine and the second compressor being arranged in on a second rotatable shaft;
• the first turbine arranged in the first overall exhaust line of the first group and the second turbine arranged in the second overall exhaust line of the second group,
• the first compressor arranged in the first overall intake line of the first group and the second compressor arranged in the second overall intake line of the second group, the first and second compressors arranged in parallel, and
• the first intake manifold of the first group and the second intake manifold of the second group connectable to one another via a connection, a first shut-off element being arranged in the connection, wherein a second shut-off element is arranged in the second overall intake line between the second compressor and the connection, wherein a third shut-off element is arranged in the second overall exhaust line, and wherein all of the shut-off elements are closed when a load of the supercharged internal combustion engine is less than a threshold.
