摘要

The invention relates to a turbocharger device (1) for an internal combustion engine (2), which comprises a turbocharger housing (3) with a first media guide channel (4) and a first impeller (6) rotatably mounted in the first media guide channel (4) a second media guide channel (5) arranged in the turbocharger housing (3) and a second running wheel (7) rotatably mounted in the second media guide channel (5), the two running wheels (6, 7) being operated with the same operating medium (8 ) are formed. The first media guide channel (4) has a first inlet (9) for the operating medium (8) and the second media guide channel (5) has a second inlet (10) separated from the first inlet (9) by at least one common first wall element (11) ) for the operating medium (8). Further aspects of the invention relate to an internal combustion engine (2) with a turbocharger device (1) and to a method for operating an internal combustion engine (2).
