Abstract
A method for operating an internal combustion engine, in which fuel is injected using an injection device into a combustion chamber of a cylinder of the internal combustion engine, a fuel quantity to be injected being ascertained as a function of individual properties of the injection device, and in which functional monitoring is performed, in which an actual torque is ascertained on the basis of performance quantities of the internal combustion engine and monitored for a deviation from a permissible torque. The individual properties of the injection device are taken into consideration when ascertaining the actual torque, where the functional monitoring is improved.
