Abstract

Es wird eine Einrichtung für ein Kraftstoffzumesssystem bei einer Brennkraftmaschine mit einer Recheneinheit zur Erzeugung eines Kraftstoffzumesssignals in Abhängigkeit von den Betriebsparametern der Brennkraftmaschine mit einer Sauerstoffsonde und einem mit dem Sondensignal be­ aufschlagten Filter und mit einer nachgeschalteten Auswer­ teschaltung zur zusätzlichen, vorzugsweise multiplikativen Beeinflussung des Kraftstoffzumesssignals vorgeschlagen, bei dem die Ausgangsgrösse des Filters zusammen mit be­ reitgestellten Drehzahlinformationen über wenigstens eine Regelfunktion zu einer zusätzlichen additiven drehzahlab­ hängigen und einer additiven drehzahlunabhängigen Beein­ flussung des Kraftstoffzumesssignals verwendet wird. Durch diese Massnahme wird eine nahezu ideale Vorsteuerung des Kraftstoffzumesssignals erreicht, was sich insbesonde­ re beim Übergangsverhalten der Brennkraftmaschine und bei ausgeschaltetem Lambda-Regelkreis positiv hinsichtlich des Fahrverhaltens und Abgasverhaltens der Brennkraftma­ schine bemerkbar macht. It becomes a device for a fuel metering system in an internal combustion engine with a computing unit for Generation of a fuel metering signal depending on the operating parameters of the internal combustion engine an oxygen probe and one with the probe signal opened filter and with a downstream ejector teschaltung for additional, preferably multiplicative Influencing the fuel metering signal proposed where the output size of the filter together with be Provided speed information on at least one Control function for an additional additive speed dependent and an additive speed independent leg Flow of the fuel metering signal is used. By this measure becomes an almost ideal precontrol of the fuel metering signal reaches what is particularly re the transition behavior of the internal combustion engine and with the lambda control circuit switched off, positive with regard to the driving behavior and exhaust behavior of the internal combustion engine seems noticeable.
