Abstract (en)

[origin: WO2010043292A1] Twin-stage exhaust turbocharging (1) for an internal combustion engine (2) with an exhaust manifold (2a), wherein the exhaust turbocharging (1) has a first (4) and a second (5) parallel high-pressure turbocharger and a sequential low-pressure turbocharger (3) arranged in the flow direction of the exhaust from the internal combustion engine (2), wherein the second high-pressure turbocharger housing (5a) and the low-pressure turbocharger housing (3a) are connected together such that the exhaust gas flows between them. The two high-pressure turbocharger housings (4a, 5a) maybe arranged on the exhaust manifold (2a) connected on one side to the exhaust manifold (2a) and to the low-pressure turbocharger housing (3a) on the other side and The exhaust from The high-pressure turbocharger housings (4a, 5a) is led to the low-pressure turbocharger housing (3a) by means of a flow channel (13) in or on the exhaust manifold (2a). Said design of the twin-stage exhaust turbocharging achieves a compact construction and a cost advantage.
