Abstract

A method and apparatus is provided for regulating stable operation of an exhaust-gas turbocharger of an internal combustion engine having a fresh-gas supply device, a switchover valve, a control device, a compressor for generating compressed air and an air-processing unit with a discharge valve. The compressor is operated in a suction intake mode in which the compressor is connected to an air inlet, and based on monitored operating parameters, the switchover valve switches the compressor from the suction intake mode into a pressure-charged in which the compressor is connected to an exhaust-gas turbocharger compressor. Based on monitored operating parameters when in the pressure-charged mode, the switchover valve switches the compressor from the pressure-charged mode into the suction intake mode.
