Schutzsystem für eine mit Aufladung betriebene Brennkraftmaschine

摘要

The invention concerns a protective system for a supercharged internal combustion engine (100), wherein it is determined by means of a quantity (P) characterizing the supercharging effect whether the boost pressure system is suffering from overshooting or a serious defect, such as for example a hose failure, and a first or second masking pattern is optionally activated in order to eliminate individual cylinders from fuel injection. If this situation is repeated, the protective system according to the invention responds substantially more rapidly than when the defect first occurs. Under certain operating conditions, defect-correction is possible and the original response speed is restored.
