Abstract

Die Erfindung betrifft ein Verfahren zur Beeinflussung der Schadstoffemissionswerte und/oder der Geräuschemissionswerte eines eine Kraftstoff-Einspritzanlage (10) aufweisenden Verbrennungsmotors, insbesondere eines Dieselmotors, wobei die Kraftstoff-Einspritzanlage (10) eine Mehrzahl von Injektoren (131) aufweist, die dazu vorgesehen sind, bei entsprechender Ansteuerung durch eine Steuereinrichtung (160), Kraftstoff in die Zylinder des Verbrennungsmotors einzuspritzen.The invention relates to a method for influencing the pollutant emission values and / or the noise emission values of a fuel injection system (10) Internal combustion engine, especially a diesel engine, wherein the fuel injection system (10) A plurality of injectors (131) are provided are, with appropriate control by a control device (160), fuel in the cylinder of the Inject internal combustion engine.

Erfindungsgemäß umfasst das Verfahren die folgenden Schritte:

  • a) Zuordnen der Mehrzahl der Injektoren (131) zu einer jeweiligen Kraftstoff-Einspritzanlage (10) derart, dass die ausgewählte Mehrzahl von Injektoren (131) in zumindest einem vorgegebenen Abschnitt der Einspritzmengen-Ansteuerdauer-Kennlinie (EM(T)) möglichst ähnliche Kennlinienverläufe aufweisen, und
  • b) Durchführen von zumindest einer adaptiven Maßnahme in Abhängigkeit von den möglichst ähnlichen Kennlinienverläufen, um die Ansteuerung der Injektoren (131) durch die Steuereinrichtung (160) zu beeinflussen.

    According to the invention, the method comprises the following steps:
  • a) Allocating the plurality of injectors (131) to a respective fuel injection system (10) in such a way that the selected plurality of injectors (131) have characteristic curves that are as similar as possible in at least one predetermined section of the injection quantity control duration characteristic (EM (T)) have, and
  • b) performing at least one adaptive measure as a function of the characteristic curves that are as similar as possible in order to influence the control of the injectors (131) by the control device (160).
