Abstract

Es wird ein elektrisch gesteuertes Kraftstoffeinspritzsy­ stem für eine Brennkraftmaschine vorgeschlagen, bei dem alle Versorgungsspannungsabhängigkeiten der elektrohyd­ raulischen Komponenten und/oder die fördermengenabhän­ gige Druckreglerkennlinie kompensiert sind. Bezüglich der Versorgungsspannungsabhängigkeit der elektrischen Kraft­ stoffpumpe geschieht dies mittels eines Korrekturfaktors zum Grundeinspritzsignal, der unterhalb eines bestimmten Spannungswerts, der demjenigen zur Aufrechterhaltung des Systemdrucks entspricht, zunehmend größere Werte annimmt. In entsprechender Weise wird die fördermenge­ nabhängige Druckreglerkennlinie in der Korrektur berück­ sichtigt. It becomes an electrically controlled fuel injection system stem proposed for an internal combustion engine, in which all supply voltage dependencies of the electrohyd physical components and / or the flow rate dependent current pressure regulator characteristic are compensated. Regarding the Supply voltage dependence of the electrical force material pump this is done by means of a correction factor to the basic injection signal, which is below a certain Voltage value, which the one to maintain the System pressure corresponds to increasingly larger values assumes. The output is correspondingly n dependent pressure regulator characteristic in the correction inspects.
