A method and apparatus for operating an internal combustion engine equipped with an exhaust gas turbo-supercharger and with a combustion chamber which supplies additional gas to the exhaust gas turbine; during idling of the internal combustion engine, the combustion chamber is operated at such partial output that with lowest possible fuel consumption of the combustion chamber, an increased starting-supercharged air-pressure, as necessary for as favorable a load acceptance behavior as possible, will establish itself in the supercharged air lines whereas during the acceleration of the internal combustion engine, the output of the combustion chamber is increased for a rapid increase of the supercharged air pressure in the supercharged air line in order to attain a spontaneous load acceptance behavior of the internal combustion engine; during a further increase of the supercharged air pressure in the supercharged air line, initiated by the increasing exhaust gas supply with an increasing internal combustion engine output, the output of the combustion chamber is then again correspondingly reduced.
