Abstract
An apparatus for regulating the exhaust gas recycling rate in an internal combustion engine having self-ignition is proposed, in which a set-point or nominal ignition delay value is ascertained, and the actual ignition delay value is regulated to this nominal value. The nominal ignition delay value is efficaciously derived from a multi-dimensional memory, the coordinate values of which are dependent on at least load and rpm. The ignition delay time is ascertained from a comparison of the signal for the injection onset of an injection nozzle, for instance, and the signal of a pressure sensor communicating with the combustion chamber.
