Abstract
A method for operating an internal combustion engine, in particular of a motor vehicle, in which fuel is injected either in a first operating mode during a compression phase, or in a second operating mode during an intake phase, directly into a combustion chamber. In both operating modes, the fuel mass injected into the combustion chamber is controlled and/or regulated as a function, among other things, of a calculated reference torque to be delivered by the internal combustion engine. A true torque delivered by the internal combustion engine and a permissible torque are determined; and the true torque is compared to the permissible torque.
