Abstract

An internal combustion engine, in particular a stationary gas engine, comprising a compressor arranged in the induction tract, in particular an exhaust gas turbocharger, an electrically operable blow-off valve connected downstream of the compressor, and a pressure sensor for detecting the pressure actual value of the mixture in the region of the blow-off valve. In according with the invention there is provided a device (9) for detecting the engine power output (N), a device (10) for calculating a pressure reference value in dependence on the detected engine power output and a relationship previously stored in a memory between engine power output (N) and pressure reference value (Psoll), and a regulating device (11) for regulating the blow-off valve (7) until the pressure actual value (Pist) reaches the calculated pressure reference value (Psoll).
