A method for regulating stable operation of an exhaust-gas turbocharger (2) of an internal combustion engine (7) having a fresh-gas supply device (4), a switchover valve (5), a control device (6), a compressor (8) and an air-processing unit (10) with a discharge valve (9), has the following method steps: operating of the compressor (8) in a suction intake mode, wherein the switchover valve (5) connects the compressor (8) to an air inlet (LE), and monitoring of operating parameters of the internal combustion engine (7), the air-processing unit (10) and the exhaust-gas turbocharger (2); regulating of the stable operation of the exhaust-gas turbocharger (2) using the monitored operating parameters by switchover of the compressor (8) from the suction intake mode into a supercharged mode, by the switchover valve (5) connecting the compressor (8) to a compressor (2a) of the exhaust-gas turbocharger (2); and switching over of the compressor (8) using the monitored operating parameters from the supercharged mode into the suction intake mode, by the switchover valve (5) connecting the compressor (8) to the air inlet (LE) again; and a corresponding apparatus. |
