Abstract (en)

[origin: EP1884646A2] The method involves computing a fuel mass from a measured fuel-pressure curve using a common-rail system, with which the mass is set as representation for controlling injection. A pressure curve (PE) of a single memory (7) is measured and a modeled pressure curve is reproduced to the curve by a hydraulic model, where the mass is computed from a hydraulic model. Deviations from the curve of the memory are computed for the modeled pressure curve and model parameters are adjusted until the deviations are smaller than a threshold value.
