Abstract
The invention relates to a multistep turbocharger arrangement (1) for an internal combustion engine with a high-pressure step (2), with a low-pressure step (3) which can be brought into operative connection to the high-pressure step (2) over a fluid passage system (4) which can be opened and closed, and with a control unit (5) for controlling the operative connection between the high-pressure step (2) and the low-pressure step (3), wherein the control unit (5) and the fluid passage system (4) are integrated in an engine exhaust manifold (6) which is disposed between the high-pressure step (2) and the low-pressure step (3).
Claims5
A multi-stage turbocharger arrangement (1) for an internal combustion engine comprising:
- a high-pressure stage (2),
- a low-pressure stage (3) which is operatively connected to the high-pressure stage (2) by means of an openable and closable flow duct system (4), and
- a regulating unit (5) for regulating the operative connection between the high-pressure stage (2) and the low-pressure stage (3), the regulating unit (5) including a regulating slide (7) and an actuator (8) for driving the regulating slide (7),
- wherein the regulating unit (5) and the flow duct system (4) are integrated in an engine exhaust-gas manifold (6) which is arranged between the high-pressure stage (2) and the low-pressure stage (3).
A multi-stage turbocharger arrangement (1) for an internal combustion engine comprising:
- a high-pressure stage (2);
- a low-pressure stage (3) which is operatively connected to the high-pressure stage (2) by means of an openable and closable flow duct system (4);
- and
- a regulating unit (5) for regulating the operative connection between the high-pressure stage (2) and the low-pressure stage (3), wherein the regulating unit (5) and the flow duct system (4) are integrated in an engine exhaust-gas manifold (6) which is arranged between the high-pressure stage (2) and the low-pressure stage (3), and wherein the regulating unit (5) has a bypass slide (9), by means of which a bypass (10) is opened and closed and which is pre-loaded into its bypass closed position.
