Abstract
The invention relates to a system for regulating an internal cumbustion engine (). Said system regulates the maximum combustion pressure by modifying the start of the injection process. The aim of the invention is to improve the operational reliability of the internal combustion engine (). To this end, the invention provides that the maximum combustion pressure (pMAX(i)) is diagnosed by the detection of a freak value. This then determines a first or second mode and sets a diagnosis value depending on the modi. The invention also provides that the output of the injection start regulator is limited by a limiting mechanism.
