Abstract: A two-stage exhaust gas turbocharging device for an internal combustion engine includes a high-pressure stage, and a low-pressure stage. The high-pressure stage and the low-pressure stage are connected via exhaust-gas lines and fresh-air lines in a gas-conducting manner. An exhaust gas of the internal combustion engine can flow first through the high-pressure turbines and then the low-pressure turbines and wherein fresh air are conveyable first through the low-pressure compressors and then through the high-pressure compressors in the direction of the internal combustion engine. The high-pressure turbines are connected to the low-pressure turbines at least in sections via a common exhaust-gas line and the low-pressure compressors to the high-pressure compressors at least in sections via a common fresh-air line.

Abstract: A two-stage exhaust gas turbocharger for an internal-combustion engine having an exhaust manifold is provided. In the exhaust gas flow direction a first high-pressure turbocharger and a second high-pressure turbocharger are arranged parallel to one another and a low-pressure turbocharger is arranged in series behind the latter. The two high-pressure turbine housings can be arranged on the exhaust manifold on one side and the low-pressure turbine housing can be arranged on the exhaust manifold on the other side. The exhaust gas coming from the high-pressure turbine housings is guided through a flow duct in or on the exhaust manifold to the low-pressure turbine housing. By way of this construction of the two-stage exhaust gas turbocharging, a compact construction is achieved resulting in cost savings.
