Abstract

A method and a device for operating an internal combustion engine make it possible from the start to avoid operating states that are characterized by an increased knock tendency or an increased exhaust gas temperature. The internal combustion engine includes a compressor in an air feed of the internal combustion engine for compression of the air supplied to the internal combustion engine. The setpoint charge pressure to be generated by the compressor is limited to a maximally allowed setpoint charge pressure as a function of a temperature at the output side of the compressor.
