Description

1515th

Die Erfindung geht aus von einer Lambda-Regelung nach der Gattung des Anspruchs und stellt einen Zusatz dar zum Gegenstand des Hauptpatents 26 38 119 und betrifft den gleichen Stand der Technik, wie er im Hauptpatent beschrieben ist und auf den daher verwiesen wird.The invention is based on a lambda control according to the preamble of the claim and provides an addition is the subject of the main patent 26 38 119 and relates to the same prior art as in Main patent is described and is therefore referred to.

Die Aufgabe der vorliegenden Erfindung besteht darin, den Anwendungsbereich der im Hauptpatent beschriebenen und im Anspruch 1 und in den Unteransprüchen des Hauptpatents angegebenen Lambda-Regelung in einen breiteren Rahmen zu stellen. Diese Aufgabe löst die Erfindung durch die kennzeichnenden Merkmale des Anspruchs und hat den Vorteil, daß nicht nur Kraftstoffeinspritzanlagen den Brennkraftmaschinen die für den jeweiligen Betriebszeitpunkt richtige Kraftstoffmenge geregelt zuführen können, sondern auch Gemischdosier- oder Aufbereitungsanlagen beliebiger Art, beispielsweise gesteuerte Vergaser. Es ist daher möglich, auch kostengünstig mit Vergasern zur Kraftstoffzumessung bestückte Brennkraftmaschinen geregelt und daher so zu betreiben, daß die jeweiligen Kraftstoff- und Luftanteile im zugeführten Gemisch präzise und innerhalb enger Grenzen gehalten bzw. um vorherbestimmbare Prozentmengen nach oben oder unten, also in Richtung fett oder mager verschoben werden können. Daher können auch mit Vergasern ausgerüstete Brennkraftmaschinen bei Kraftfahrzeugen o. dgl. mit der Katalysatortechnik ausgestattet werden. So kann beispielsweise in Abhängigkeit zu den Sondensignalen der Düsenquerschnitt im Vergaserbereich geändert werden.The object of the present invention is the scope of the described in the main patent and in claim 1 and in the subclaims of the main patent specified lambda control to put in a broader framework. This object is achieved by the invention by the characterizing Features of the claim and has the advantage that not only fuel injection systems are the internal combustion engines can supply the correct amount of fuel for the respective operating time in a regulated manner, but rather also mixture dosing or processing systems of any kind, for example controlled carburetors. It is therefore possible, also cost-effectively equipped with carburetors for fuel metering internal combustion engines regulated and therefore operated in such a way that the respective fuel and air proportions in the supplied mixture precise and kept within narrow limits or by predeterminable percentages upwards or down, so in the direction of fat or lean can be shifted. That is why they can also be equipped with carburettors Internal combustion engines in motor vehicles or the like can be equipped with catalyst technology. For example, the nozzle cross-section in the carburetor area can be changed as a function of the probe signals will.

Schließlich ist es möglich, nicht auf der Seite der zugeführten Kraftstoffmenge zu regeln, sondern unter Zugrundelegung der Lambda-Regelung die rückgeführte Abgasmenge zu beeinflussen, oder Luftbypaßleitungen der Lambda-Regelung zu unterwerfen.Finally, it is possible not to regulate on the side of the amount of fuel supplied, but on the basis of it the lambda control to influence the recirculated exhaust gas quantity, or air bypass lines subject to the lambda control.

Figuren und Beschreibung sind, da sie mit dem Hauptpatent identisch sind, an dieser Stelle entbehtlich. Es wird auf die Ausführungen des Hauptpatents verwiesen. Since they are identical to the main patent, the figures and description are dispensed with at this point. Reference is made to the statements of the main patent.
