Patent ID: 8312721

Claim:
An exhaust gas assembly comprising: a manifold constructed as a cast component and having a high-pressure connection and a low-pressure connection, and an exhaust gas inlet and an exhaust gas outlet, an exhaust gas manifold having an inner housing and an outer housing, said exhaust gas manifold connected to the exhaust gas inlet, an adjusting member arranged inside the manifold, with the adjusting member configured to supply exhaust gas to the low pressure connection or the high-pressure connection, or both, of the manifold, a high-pressure turbine comprising a high-pressure turbine housing connected to the high-pressure connection of the manifold and a low pressure turbine comprising a low-pressure turbine housing connected to the low-pressure connection of the manifold, said high-pressure turbine housing and said low pressure turbine housing each having respective inner and outer housings made of sheet metal shells, and a connecting channel extending through the manifold and connecting a high-pressure exhaust gas outlet of the high-pressure turbine housing with a low pressure exhaust gas inlet of the low pressure turbine housing.
