PROBLEM TO BE SOLVED: To provide an exhaust-gas turbocharger with acoustically active imperfections.SOLUTION: The exhaust-gas turbocharger (1) has a turbine housing (2) having a bypass duct (10) provided with a bypass opening (9); and a control flap (3) mounted pivotably between a closed position and an open position in the turbine housing (2), and when in the closed position, resting on a bearing region (8) of a housing wall (11) which conducts exhaust gas and contains the bypass opening (9). At least one flow imperfection (12A, 12B; 23A, 23B) is arranged in the turbine housing wall (11) in the bearing region (8) of the control flap (3) and/or in the control flap (3). |
