Estimating the term…
In a radial compressor, particularly of an exhaust gas turbocharger of an internal combustion engine, having a compressor housing within which a compressor wheel is disposed for compressing air from an inflow channel of the compressor housing and directing the air to an outflow channel of the compressor housing, the compressor housing comprising a bypass channel having a first flow opening upstream of an axial compressor wheel inlet and a second flow opening downstream of the compressor wheel inlet, the compressor housing is configured at least in a flow region upstream of the second flow opening in an asymmetric manner with regard to a rotational axis of the compressor wheel.
A radial compressor, particularly for an exhaust gas turbocharger of an internal combustion engine, said radial compressor having a compressor housing (10) with an inflow channel (14), an outflow channel (16), and a compressor wheel (12) disposed within the compressor housing (10) for compressing air inducted from the inflow channel (14) of the compressor housing (10) and for guiding the air into the outflow channel (16) of the compressor housing (10), the compressor housing (10) including a bypass channel (18) having at least a first flow opening (20a) upstream of an axial compressor wheel inlet (22) and a second flow opening (20b) disposed downstream of the compressor wheel inlet (22), the compressor housing (10) being formed at least in one flow region (II-II) upstream of the outflow channel (16) with radially inner and radially outer channel walls (26a, 26b) forming an annular bypass channel (18) which is circumferentially asymmetric with regard to a rotational axis (D) of the compressor wheel (12).
A motor vehicle with an internal combustion engine including an exhaust gas turbocharger having a radial compressor arranged in an intake section of the internal combustion engine, said radial compressor having a compressor housing (10) with an inflow channel (14), an outflow channel (16), and a compressor wheel (12) disposed within the compressor housing (10) for compressing air inducted from an inflow channel (14) of the compressor housing (10) and for guiding the air into the outflow channel (16) of the compressor housing (10), the compressor housing (10) including a bypass channel (18) having at least a first flow opening (20a) upstream of an axial compressor wheel inlet (22) and a second flow opening (20b) disposed downstream of the compressor wheel inlet (22), the compressor housing (10) being at least in one flow region (II-II) upstream of the outflow channel (16) asymmetric with regard to a rotational axis (D) of the compressor wheel (12) in that radially inner and radially outer channel walls (26a, 26b) form an annular bypass channel (18) which is formed circumferentially asymmetric with respect to the rotational axis (D) of the compressor wheel (12).
