Abstract (en)

[origin: EP0579967A2] A method and a device are described for determining the quantity of fuel (QK) fed to an internal combustion engine, especially for a spontaneous ignition internal combustion engine. In this a first signal (QSD) is determined, which gives the fuel quantity on the basis of a signal or an injection period (SD). In addition at least one further signal indicating the fuel quantity is detected. For determining the fuel quantity signal (QK) a mean value is formed from the first signal (QSD) and the further signal (QRW, QED, QMD).
