  • Exhaust gas system for an internal combustion engine
    Patent number: 9267418
    Abstract: An exhaust gas system for an internal combustion engine includes at least one first and one second exhaust gas connection interface for fluidically separated discharge of exhaust gas arising during a combustion process from a combustion chamber of the internal combustion engine, and one at least dual-pipe exhaust gas turbocharger having at least one first and one second supply connection interface for fluidically separated supply of the exhaust gases arising during the combustion process, wherein a first connecting channel is designed for fluidic connection of the first exhaust gas connection interface to the first supply connection interface, and a second connecting channel is designed for fluidic connection of the second exhaust gas connection interface to the second supply connection interface. At least one of the connecting channels is designed to be at least partially closable by a closure element.
