Abstract (en)

[origin: DE102006006303B3] A process estimates the amount of fuel injected in a single operation to single cylinder in a fuel-injected multi-cylinder automotive piston engine. The segmented time-lapse in which the single injection takes place, is numerically evaluated by generating a second time-lapse derivation. The second segmented time-lapse derivation provides a corrected injection parameter, based on a combined test quantity and test moment performance diagram.
