    Abstract: An internal combustion engine with an exhaust gas recirculation device has two cylinder groups, the exhaust gas from which can be discharged separately via a respective exhaust pipe. The recirculation line of the exhaust gas recirculation device branches off from one of the exhaust pipes and opens out into the induction section of the internal combustion engine. The cylinder groups can be operated with different power outputs, the recirculation line of the exhaust gas recirculation device branching off from the exhaust pipe of the cylinder group with a variable power output.
