Abstract

A method for operating an internal combustion engine, e.g., of a motor vehicle, where fuel is supplied under pressure via at least one injection valve. The injected fuel quantity is influenced by the injection time of injection valve. In order to be able to provide optimum operating comfort and good component reliability even in the event of an incorrect fuel pressure, a maximum allowable torque of the internal combustion engine that is dependent on the instantaneous fuel pressure is determined.
