Abstract

In an internal combustion engine for a motor vehicle, having a first cylinder bank and a second cylinder bank and an exhaust tract including a first exhaust manifold and a second exhaust manifold with a first exhaust gas duct and a second exhaust gas duct and a first exhaust gas turbocharger including a first turbine situated in the exhaust tract and a second exhaust gas turbocharger including a second turbine arranged in the exhaust tract, the first turbine and the second turbine are selectively drivable in alternation by at least a portion of the exhaust gas via a valve device that is switchable between at least three positions and is situated upstream from the first turbine and the second turbine so that, in a first position of the valve device, the engine is operated in a pulse supercharging mode; in a second position of the valve device, the engine is operated in a ram charging mode and in a third position of the valve device, the engine is operated in a sequential supercharging mode.
