  • Two-stage exhaust gas turbocharging arrangement for an internal combustion engine
    Patent number: 8453447
    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.
