Abstract

In a method for limiting the power output of an internal combustion engine, an air mass flow deviation of an actual air mass flow (mL(IST)) from a reference air mass flow (ML(REF)) is determined and, depending on the air mass flow deviation, a power output reduction is determined by which the maximum power output limit of the internal combustion engine is to be reduced in order to prevent overheating of the internal combustion engine.
