ABSTRACT:
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.
