ABSTRACT:
The invention is directed to a method for operating an internal combustion engine (1) having a compressor (5) which method makes possible an actualization of a pump limit of the compressor (5). A pressure ratio across the compressor (5) is limited in dependence upon a mass flow through the compressor (5) by means of the pump limit in order to prevent a pumping of the compressor (5). In at least one operating state of the engine (1), a check is made as to whether a pumping of the compressor (5) occurs. The pump limit is corrected in dependence upon the test results.
