Abstract

Bei einem Verfahren zum Betrieb einer Brennkraftmaschine mit Hilfe einer Steuereinrichtung, die einen elektronischen Speicher für vorgegebene, für das Leistungsverhalten der Brennkraftmaschine relevante Programmdaten (Soll-Leistungsdaten) enthält, werden die Soll-Leistungsdaten zusätzlich abgespeichert und die Soll-Leistungsdaten mit den aktuellen, für das Leistungsverhalten der Brennkraftmaschine relevanten Programmdaten (Ist-Leistungsdaten) verglichen und die Ist-Leistungsdaten abgespeichert, wenn sie gegenüber den Soll-Leistungsdaten verändert sind.In a method for operating an internal combustion engine with the aid of a control device, which is an electronic memory for predetermined, for performance program data relevant to the internal combustion engine (target performance data) contains, the target performance data are additionally stored and the target performance data with the current, for the performance of the internal combustion engine relevant program data (actual performance data) compared and the actual performance data saved if it changes compared to the target performance data are.
