A method for triggering an internal combustion engine of a certain type according to a state machine is provided, in which a possible operating state of the engine, which is assigned to a layer n of the state machine, is first set. In an additional layer (n+1), sub-states to the previously determined operating state are specified. For triggering different type engines, the method provides that the state machine has at least two groups of layers, the first group of layers representing operating states that the engine of the certain type has in common with engines of another type, and the second group of layers representing operating states that are specific to the engine of the certain type.

With a protection system for a turbocharged internal combustion engine, it is determined, using a parameter characterizing the turbocharging, whether an overshoot or a serious defect, such as for example a hose failure, is present in the turbocharging pressure system and, according to the case, a 1st or 2nd suppression pattern for suppressing fuel injection to individual cylinders is activated. In the event of repeat occurrences, the protection system according to the invention responds considerably faster than in the first occurrence of the defect. An error correction is possible under certain operating conditions, and the original response time is restored.
