Method for operating internal combustion engines

An increase of power output of internal combustion engines (10) commonly needs to be performed rapidly. For quickly satisfying at least temporarily an increase of power output of internal combustion engines (10), the disclosed method for supporting an increase of the power output when operating an internal combustion engine (10) may comprise operating the internal combustion engine (10) by supplying an amount of charged air and fuel to the at least one cylinder (26) and combusting this mixture therein, monitoring at least one engine parameter, determining a temporal change of the at least one engine parameter and/or a mismatch of the at least one engine parameter with a predetermined engine parameter table, and supplying pressurized gaseous fluid in addition to the charged air to the at least one cylinder (26), when the determined temporal change and/or the determined mismatch exceed a predetermined respective threshold.
