Regulating compressor, especially in internal combustion engine exhaust system, involves determining range of fluctuation of state parameter to establish current compressor working point

摘要

The method involves monitoring a state parameter describing the compressor (4) characteristics and making a control intervention in the event that the state parameter exceeds or falls below a threshold. The range of fluctuation of the state parameter about a mean value is determined to establish the current working point within the compressor's characteristic field. Independent claims are also included for the following: an arrangement for regulating a compressor, especially in an internal combustion engine exhaust system.
