Abstract
In a fuel supply system for an internal combustion engine, significant parameters such as fuel pressure and fuel flow rate are determined continuously from measured variables with the aid of an observer. These variables which have been determined are used to achieve fuel delivery performed with regard to a requirement, the control operations being carried out as a function of requirements of the internal combustion engine by the control unit itself.
