Abstract

Bei Verdichtungszündungsmotoren wird, wenn ein oder mehrere Zylinder nicht zünden, Kraftstoff über das Auslasssystem des Motors ausgestoßen, wobei sich die Abgase derart verändern, dass eine als "Weißer Rauch" bekannte Erscheinung auftritt. Als Ergebnis strengerer Regierungs- sowie Verbraucheranforderungen bezüglich Kraftstoffverbrauch, Verhalten und Abgasen ist eine Reduzierung dieses weißen Rauchs wünschenswert.In compression ignition engines, if one or more Do not ignite the fuel through the exhaust system of the cylinder Engine ejected, the exhaust gases changing in such a way that a phenomenon known as "white smoke" occurs. As Result of stricter government and consumer requirements regarding fuel consumption, behavior and emissions is one Reduction of this white smoke is desirable.

Es wird ein Kraftstoffzufuhrsteuerungssystem (10) für einen Motor (12) mit einer Mehrzahl von Zylindern (26 - 36) und einer Kraftstoffzufuhreinheit (38) zur Steuerung der an die jeweiligen Zylinder (26 - 36) gelieferten Kraftstoffmenge in Abhängigkeit von an die Kraftstoffzufuhreinheit (38) gelieferten Steuersignalen, und einer Steuereinheit (40) zur Erzeugung dieser Steuersignale und ein Verfahren zur Steuerung der Kraftstoffzufuhr an einem mehrere Zylinder (26 - 36) aufweisenden Motor (12) vorgeschlagen.

Figure 00000001
The invention relates to a fuel supply control system (10) for an engine (12) with a plurality of cylinders (26 - 36) and a fuel supply unit (38) for controlling the quantity of fuel supplied to the respective cylinders (26 - 36) as a function of the fuel supply unit ( 38), and a control unit (40) for generating these control signals and a method for controlling the fuel supply to an engine (12) having a plurality of cylinders (26 - 36).
