Abstract

In einer Einrichtung zur zeitgesteuerten Ansteuerung elektromagnetisch betätigbarer Kraftstoffeinspritzventile von Brennkraftmaschinen ist eine Einspritzelektronik vorge­ sehen, mit der in Abhängigkeit von einer Steuergröße, der Luftmenge, das Kraftstoffeinspritzventil durch einen Stro­ mimpuls geöffnet wird. Da die für einen Stromimpuls vorgegebener Dauer zudosierte Kraftstoffmenge von der Kennung des Kraftstoffeinspritzventils, d.h. Abweichungen von einer Sollkennung, abhängt, ist an jedem Kraftstoffeins­ pritzventil (1-14) ein elektrischer Widerstand (16) angeord­ net, der proportional der Kenngröße, bzw. der Abweichung von der Sollkenngröße, des Kraftstoffeinspritzventils dimen­ sioniert ist. Der Widerstand steht mit der Einspritzelektronik (18, 22) zur Beeinflussung der Einspritzzeit in Verbindung, um Abweichungen der Kennung von einer Sollgröße au­ szugleichen. In a device for time-controlled control Electromagnetically actuated fuel injection valves from Internal combustion engines are pre-injected electronics see, with the, depending on a tax quantity, the Air flow, the fuel injector through a strobe mimpuls is opened. Because that's for a current pulse amount of fuel metered in from the predetermined duration Identification of the fuel injector, i.e. Deviations depends on a target identifier, is on each fuel injection valve (1-14) an electrical resistor (16) is arranged net, which is proportional to the parameter or the deviation dimen from the target parameter of the fuel injector is based. The resistance is with the injection electronics (18, 22) for influencing the injection time in connection, to deviations of the identifier from a target value equals.
