Description

Die Erfindung betrifft eine Anordnung mit einem elek­tronischen Regler für Brennkraftmaschinen, insbeson­dere für Einspritzmotoren, bei welcher der Regler mit mehreren Sensoren und mindestens einem Stell­glied funktionell verbunden ist.The invention relates to an arrangement with an electronic controller for internal combustion engines, in particular for injection engines, in which the controller is functionally connected to a plurality of sensors and at least one actuator.

Elektronische Regelsysteme für Brennkraftmaschinen bestehen aus mehreren Komponenten, wie beispiels­weise Sensoren, dem Regler und Stellgliedern, welche bei bekannten Systemen an der Brennkraftmaschine bzw. im Motorraum eines Kraftfahrzeuges verteilt angeordnet sind. Dadurch sind entsprechende Steckver­bindungen und Leitungen erforderlich, welche Anlaß für Defekte sein können. Außerdem bedeuten die Steck­verbindungen und die Leitungen einen zusätzlichen Aufwand. Hinzu kommt eine entsprechende Zahl von Schutzgehäusen bzw. Schutzkappen, welche die Kompo­nenten oder mindestens die Anschlüsse der Komponen­ten vor äußeren Einflüssen (Feuchtigkeit, Schmutz) schützen.Electronic control systems for internal combustion engines consist of several components, such as sensors, the controller and actuators, which in known systems are distributed on the internal combustion engine or in the engine compartment of a motor vehicle. As a result, appropriate plug connections and lines are required, which can give rise to defects. In addition, the plug connections and the lines mean additional effort. There is also a corresponding number of protective housings or protective caps which protect the components or at least the connections of the components from external influences (moisture, dirt) protect.

Aufgabe der vorliegenden Erfindung ist es daher, eine Anordnung mit einem elektronischen Regler für Brennkraftmaschinen anzugeben, bei welcher Leitungen und Steckverbindungen auf ein Mindestmaß reduziert werden.The object of the present invention is therefore to provide an arrangement with an electronic controller for internal combustion engines, in which lines and plug connections are reduced to a minimum.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Regler Teil einer Baugruppe ist, die ferner eine Drosselklappen-Anordnung, einen Luftmassensen­sor und einen Drosselklappen-Stellungssensor umfaßt.This object is achieved in that the controller is part of an assembly which further comprises a throttle valve arrangement, an air mass sensor and a throttle valve position sensor.

Außer dem Vorteil, daß lange und störanfällige Verbindungsleitungen entfallen, ergibt sich der Vorteil, daß für Wartungs- und Reparaturarbeiten die geschlossene Baugruppe von der Brennkraftmaschine entfernt und beispielsweise auf einem Prüfstand durchgemessen werden kann.In addition to the advantage that long and fault-prone connecting lines are eliminated, there is the advantage that the closed assembly can be removed from the internal combustion engine for maintenance and repair work and measured, for example, on a test bench.

Eine Weiterbildung der Erfindung ist dadurch gekenn­zeichnet, daß ein Gehäuse mit dem Ansaugkanal der Brennkraftmaschine verbindbar ist, daß die Drossel­klappen-Anordnung in einem die Verbindung zwischen dem Gehäuse und Ansaugkanal bildenden Rohrstück vorgesehen ist und daß der Luftmassensensor in dem Gehäuse und der Regler an einer Wand des Gehäuses angeordnet ist. Diese Weiterbildung ermöglicht eine äußerst günstige Verbindung der Baugruppe mit der Brennkraftmaschine.A further development of the invention is characterized in that a housing can be connected to the intake duct of the internal combustion engine, that the throttle valve arrangement is provided in a piece of pipe which forms the connection between the housing and intake duct, and that the air mass sensor in the housing and the controller on a wall of the housing is arranged. This development enables an extremely favorable connection of the assembly to the internal combustion engine.

Eine andere Weiterbildung besteht darin, daß inner­halb des Gehäuses ein Einspritzventil angeordnet ist, welches dem Regler als Stellglied zugeordnet ist Diese Weiterbildung läßt sich mit Vorteil bei Einspritzmotoren mit sogenannter Zentraleinspritzung anwenden, bei welcher lediglich ein Einspritzventil für sämtliche Zylinder vorgesehen ist. Die Erfindung läßt sich jedoch auch in vorteilhafter Weise bei Brennkraftmaschinen anwenden, bei denen jeweils für einen Zylinder ein Einspritzventil vorgesehen ist.Another development is that an injection valve is arranged within the housing, which is assigned to the controller as an actuator. This development can be used advantageously Use injection engines with so-called central injection, in which only one injection valve is provided for all cylinders. However, the invention can also be used advantageously in internal combustion engines in which an injection valve is provided for each cylinder.

Eine weitere Verbesserung der Erfindung ist dadurch gegeben, daß an einer Außenwand des Gehäuses eine Luftfilter-Anordnung anbringbar ist, welche ein kreisförmiges Luftfilter aufweist, und daß der von dem kreisförmigen Luftfilter gebildete Innenraum mit dem Innenraum des Gehäuses über einen Strömungskanal verbunden ist, in welchem der Luftmassensensor angeordnet ist. Dabei ist eine weitere günstige Aus­führungsform möglich, bei welcher der elektronische Regler auf der Außenwand des Gehäuses angeordnet ist und in den Innenraum der Luftfilter-Anordnung hinein­ragt.A further improvement of the invention is given in that an air filter arrangement can be attached to an outer wall of the housing, which has a circular air filter, and in that the interior formed by the circular air filter is connected to the interior of the housing via a flow channel in which the air mass sensor is arranged. A further favorable embodiment is possible in which the electronic controller is arranged on the outer wall of the housing and projects into the interior of the air filter arrangement.

Hierdurch ist eine gute Kühlung des elektronischen Reglers durch die angesaugte und gefilterte Außen­luft gegeben.This ensures good cooling of the electronic controller by the sucked in and filtered outside air.

Gemäß einer anderen Weiterbildung können im Innen­raum der Luftfilter-Anordnung außerdem ein Drucksen­sor und/oder ein Temperatursensor angeordnet sein. Außerdem besteht die Möglichkeit, im Bereich der Drosselklappen-Anordnung einen Motortemperatursensor und/oder einen Saugrohrtemperatursensor vorzusehen.According to another development, a pressure sensor and / or a temperature sensor can also be arranged in the interior of the air filter arrangement. It is also possible to provide an engine temperature sensor and / or an intake manifold temperature sensor in the area of the throttle valve arrangement.

Schließlich kann gemäß einer anderen Weiterbildung die die Drosselklappe tragende Welle mit einem Schalter in Wirkverbindung stehen, der bei der Leer­laufstellung der Drosselklappe anspricht.Finally, according to another development, the shaft carrying the throttle valve can be operatively connected to a switch which responds when the throttle valve is in the idle position.

Die erfindungsgemäße Anordnung kann bei verschiede­nen Regelsystemen für Brennkraftmaschinen angewendet werden. Eine bevorzugte Anwendung ist die an sich bekannte Regelung der Kraftstoff-Einspritzmenge bei Otto-Motoren mit Kraftstoffeinspritzung. Zur Rege­lung der Einspritzmenge wird bei den bekannten Regel­systemen in erster Linie die vom Motor angesaugte Luftmasse herangezogen. Es werden zur Regelung je­doch auch die Drosselklappen-Stellung, der äußere Luftdruck (also die Höhe), die Motortemperatur, die Außenlufttemperatur, die Motordrehzahl und das Meß­ergebnis einer Lambdasonde berücksichtigt. Bei den erfindungsgemäßen Anordnungen können mehrere, diese Größen erfassenden Sensoren innerhalb der Baugruppe angeordnet sein. Es können jedoch auch zusätzliche Sensoren (z. B. Motordrehzahl, Lambdasonde) über entsprechende Leitungen mit der Baugruppe verbunden sein.The arrangement according to the invention can be used in various control systems for internal combustion engines. A preferred application is the known control of the fuel injection quantity in gasoline engines with fuel injection. In the known control systems, the air mass sucked in by the engine is primarily used to control the injection quantity. However, the throttle valve position, the external air pressure (i.e. the altitude), the engine temperature, the outside air temperature, the engine speed and the measurement result of a lambda sensor are also taken into account for the control. In the arrangements according to the invention, a plurality of sensors measuring these variables can be arranged within the assembly. However, additional sensors (e.g. engine speed, lambda sensor) can also be connected to the module via corresponding lines.

Die bekannten Regelsysteme lassen sich auch mit einer Leerlaufregelung verbinden, wozu bei der erfin­dungsgemäßen Anordnung im Bereich der Drosselklap­pen-Anordnung ein Leerlaufsteller vorgesehen ist.The known control systems can also be connected to an idle control, for which purpose an idle actuator is provided in the arrangement according to the invention in the region of the throttle valve arrangement.

Ferner ist die erfindungsgemäße Anordnung nicht auf eine mechanische Betätigung der Drosselklappe be­schränkt. Eine Weiterbildung der Erfindung besteht vielmehr darin, daß der elektronische Regler einen Regler einer elektronischen Gaspedal-Anlage umfaßt und daß die Drosselklappen-Anordnung mit einem elek­tromotorischen Stellglied versehen ist, welches an einem dafür vorgesehenen Ausgang des elektronischen Reglers angeschlossen ist.Furthermore, the arrangement according to the invention is not limited to mechanical actuation of the throttle valve. A further development of the invention is rather that the electronic regulator comprises a regulator of an electronic accelerator pedal system and that the throttle valve arrangement is provided with an electromotive actuator which is connected to an output of the electronic regulator provided therefor.

Vorteilhafterweise können die Leitungen zwischen den vorhandenen Sensoren sowie Stellgliedern und dem elektronischen Regler mindestens teilweise innerhalb des Gehäuses geführt sein.The lines between the existing sensors and actuators and the electronic controller can advantageously be routed at least partially within the housing.

Die Erfindung läßt zahlreiche Ausführungsformen zu. Zwei davon sind schematisch in der Zeichnung an Hand mehrerer Figuren dargestellt und nachfolgend beschrieben. Es zeigt:

  • Fig. 1 ein erstes Ausführungsbeispiel, bei welchem als Sensoren lediglich ein Luftmassensensor und ein Drosselklappen-Stellungssensor vorge­sehen sind,
  • Fig. 2 ein Ausführungsbeispiel mit mehreren Sensoren und
  • Fig. 3 eine schematische Darstellung des Reglers und der Sensorschaltungen
The invention allows numerous embodiments. Two of these are shown schematically in the drawing using several figures and described below. It shows:
  • 1 shows a first embodiment in which only an air mass sensor and a throttle valve position sensor are provided as sensors,
  • Fig. 2 shows an embodiment with several sensors and
  • Fig. 3 is a schematic representation of the controller and the sensor circuits

Gleiche Teile sind in den Figuren mit gleichen Bezugszeichen versehen.Identical parts are provided with the same reference symbols in the figures.

Bei der Anordnung nach Fig. 1 ist ein die Form eines flachen Zylinders aufweisendes Gehäuse 1 auf ein Rohr 2 aufgesetzt, welches eine Drosselklappe 3 enthält, welche auf einer Welle 4 befestigt ist. Oberhalb der Öffnung des Rohres 2 ist ein Kraft­stoff-Einspritzventil 5 mit einer Düse 6 angeordnet. Das Gehäuse 1 wird von einer Wand 7 nach oben abge­schlossen, auf welche ein Luftfilter 8 aufgesetzt ist. Das an sich bekannte Luftfilter 8 besteht aus einem kreisringförmigen Filter 9, das einen Hohlraum bildet. Der Innenraum 10 des Luftfilters sowie der Innenraum 11 des Gehäuses 1 sind durch einen Strömungskanal 13 verbunden. Der Strömungskanal ent­hält einen Luftmassensensor 12 und ist zur Erzielung einer möglichst laminaren Strömung relativ lang aus­gebildet. Um dieses auf kleinem Raum zu erreichen, ist der Strömungskanal 13 kreisringförmig an der Außenwand des Gehäuses 1 entlanggeführt. An der Ein­trittsöffnung 14, welche gleichzeitig eine Öffnung in der Wand 7 darstellt, tritt die gefilterte Luft in den Strömungskanal 13 ein, streicht am Sensor 12 vorbei und wird über die Austrittsöffnung 15 in den übrigen Hohlraum 11 des Gehäuses 1 geführt. Der Hohl­raum 11 dient im übrigen zur Dämpfung der Pulsation im Ansaugkanal.In the arrangement according to FIG. 1, a housing 1 having the shape of a flat cylinder is placed on a tube 2, which contains a throttle valve 3, which is fastened on a shaft 4. A fuel injection valve 5 with a nozzle 6 is arranged above the opening of the tube 2. The housing 1 is closed off from a wall 7 on which an air filter 8 is placed. The air filter 8 known per se consists of an annular filter 9 which forms a cavity. The interior 10 of the air filter as well the interior 11 of the housing 1 are connected by a flow channel 13. The flow channel contains an air mass sensor 12 and is designed to be relatively long in order to achieve a flow that is as laminar as possible. In order to achieve this in a small space, the flow channel 13 is guided in a ring along the outer wall of the housing 1. At the inlet opening 14, which also represents an opening in the wall 7, the filtered air enters the flow channel 13, sweeps past the sensor 12 and is guided via the outlet opening 15 into the remaining cavity 11 of the housing 1. The cavity 11 also serves to dampen the pulsation in the intake duct.

Auf der Zwischenwand 7 ist ein elektronischer Regler angeordnet, der bezüglich seiner Funktion bekannt ist und im einzelnen nicht näher beschrieben zu werden braucht. Dem elektronischen Regler 15 werden als Eingangsgrößen die Meßsignale des Luftmassen­sensors 12 und eines Drosselklappen-Stellungssensors 16 zugeführt. Der Drosselklappen-Stellungssensor 16 besteht in an sich bekannter Weise aus einem Poten­tiometer, dessen Schleifer mit der Drosselklappen­Welle 4 gekoppelt ist. Ferner ist für eine Umschal­tung der Regelung für den Leerlaufbetrieb ein Schal­ter 17 in ebenfalls bekannter Weise mit der Drossel­klappen-Welle 4 verbunden und an den elektronischen Regler 15 angeschlossen.An electronic controller is arranged on the intermediate wall 7, the function of which is known and need not be described in detail. The measurement signals of the air mass sensor 12 and a throttle valve position sensor 16 are supplied to the electronic controller 15 as input variables. The throttle valve position sensor 16 consists, in a manner known per se, of a potentiometer, the slider of which is coupled to the throttle valve shaft 4. Furthermore, a switch 17 is connected in a known manner to the throttle valve shaft 4 and connected to the electronic controller 15 for switching the control for idle operation.

Die Ausgangssignale des Reglers 15 werden über kurze Leitungen dem Kraftstoff-Einspritzventil 5 zuge­führt. Bei dem dargestellten Ausführungsbeispiel ist das Kraftstoff-Einspritzventil 5 mit einem System­druckregler 18 kombiniert. Zur Verbindung mit einem Kraftsofftank 19 dienen die Kraftstoffzuleitung 20 und die Kraftstoffrückleitung 21. Schließlich wird über eine ebenfalls lediglich schematisch dargestell­te elektrische Leitung 22 dem Regler 15 Betriebs­spannung zugeführt. Um eine Auswirkung von Schwankun­gen der Spannung des Bordnetzes auf den Regler zu vermeiden, ist der Regler 15 mit einer Spannungs­stabilisierungs-Schaltung (in Fig. 1 nicht darge­stellt) versehen.The output signals of the controller 15 are fed to the fuel injection valve 5 via short lines. In the exemplary embodiment shown, the fuel injection valve 5 is combined with a system pressure regulator 18. To connect with one Fuel tank 19 serves the fuel supply line 20 and the fuel return line 21. Finally, operating voltage is supplied to the controller 15 via an electrical line 22, which is also only shown schematically. In order to avoid the effect of fluctuations in the voltage of the vehicle electrical system on the controller, the controller 15 is provided with a voltage stabilization circuit (not shown in FIG. 1).

Zur Verdeutlichung des Verlaufs des Strömungskanals ist in Fig. 1a ein Querschnitt durch das Gehäuse 1 dargestellt, in welchem auch ein Strömungsgleichrich­ter 41 und ein Schutzgitter 42 gezeigt ist, welche in Fig. 1 der Übersichtlichkeit halber fortgelassen wurden.To illustrate the course of the flow channel, a cross section through the housing 1 is shown in FIG. 1 a, in which a flow straightener 41 and a protective grille 42 are also shown, which have been omitted in FIG. 1 for the sake of clarity.

Das Ausführungsbeispiel gemäß Fig. 2 setzt ein Regel­system mit mehr Möglichkeiten voraus. Dazu wird dem Regler 15 außer den im Zusammenhang mit Fig. 1 erläu­terten Eingangsgrößen noch über einen im Innenraum des Luftfilters 8 angeordneten Drucksensor 24 eine Information über den Außenluftdruck, also die Höhe, gegeben.The embodiment according to FIG. 2 requires a control system with more options. For this purpose, in addition to the input variables explained in connection with FIG. 1, the controller 15 is also provided with information about the outside air pressure, that is to say the height, via a pressure sensor 24 arranged in the interior of the air filter 8.

Ebenfalls im Innenraum 10 des Luftfilters 8 ist ein Temperatursensor 25 vorgesehen, welcher die Tempera­tur der Ansaugluft ermittelt.A temperature sensor 25, which determines the temperature of the intake air, is also provided in the interior 10 of the air filter 8.

Für verschiedene bekannte Regelsysteme wird als eine der Eingangsgrößen die Motortemperatur benötigt. Hierfür kann bei der erfindungsgemäßen Anordnung stellvertretend die Saugrohrtemperatur in der Nähe der Drosselklappen-Anordnung durch einen weiteren Sensor 26 ermittelt werden.The motor temperature is required as one of the input variables for various known control systems. In the arrangement according to the invention, the intake manifold temperature in the vicinity of the throttle valve arrangement can be determined for this by a further sensor 26.

Schließlich kann das Regelsystem noch eine soge­nannte elektronische Gaspedal-Anlage umfassen, bei welcher die Stellung des Gaspedals in eine elek­trische Größe umgewandelt wird, welche über einen Regler auf die Drosselklappe einwirkt. Hierzu kann der Regler 15 entsprechend ausgelegt sein und einen zusätzlichen Ausgang aufweisen, an welchen ein elek­tromotorisches Drosselklappen-Stellglied 27 ange­schlossen ist.Finally, the control system can also comprise what is known as an electronic accelerator pedal system, in which the position of the accelerator pedal is converted into an electrical variable which acts on the throttle valve via a controller. For this purpose, the controller 15 can be designed accordingly and have an additional output to which an electromotive throttle valve actuator 27 is connected.

Fig. 3 zeigt schematisch, teilweise als Blockschalt­bild, die elektrische Schaltung der Anordnungen nach den Figuren 1 und 2. Einige der in Frage kommenden Sensoren benötigen zu ihrem Betrieb elektrische Schaltungen, welche speziell an die Art der Sensoren angepaßt sind. Es sind ferner Sensoren bekannt, welche sehr kleine elektrische Signale abgeben, die vor ihrer weiteren Auswertung verstärkt werden müs­sen. Hierzu werden häufig direkt an den Sensoren elektrische Schaltungen angeordnet. Wegen des kompak­ten Aufbaus der erfindungsgemäßen Anordnung ist es möglich, derartige Schaltungen mit dem Regler 15 innerhalb eines Gehäuses 31 zusammenzufassen.3 shows schematically, partly as a block diagram, the electrical circuit of the arrangements according to FIGS. 1 and 2. Some of the sensors in question require electrical circuits for their operation, which are specially adapted to the type of sensors. Sensors are also known which emit very small electrical signals which must be amplified before they can be evaluated further. For this purpose, electrical circuits are often arranged directly on the sensors. Because of the compact structure of the arrangement according to the invention, it is possible to combine such circuits with the controller 15 within a housing 31.

Je nach Art der Anwendung kann es vorteilhaft sein, die zu den einzelnen Sensoren gehörenden Schaltungen - im folgenden Sensorschaltungen genannt - jeweils als separate Bausteine 32, 33, 34 aufzubauen, welche lediglich durch wenige Leitungen mit dem Regler 15 und dem jeweils zugehörigen Sensor 12, 26, 16 verbun­den sind. Diese Anordnung hat den Vorteil, daß bei einer Anpassung der erfindungsgemäßen Anordnung an beispielsweise verschiedenen Brennkraftmaschinen, für welche verschiedene Sensoren erforderlich sind, lediglich ein oder mehrere der Bausteine 32, 33, 34 auszuwechseln sind. Zur Verbindung der jeweiligen Sensorschaltung 32, 33, 34 mit dem Regler 15, wel­cher auch gleichzeitig die Versorgung der Sensor­schaltungen mit der Betriebsspannung übernimmt, erfolgt grundsätzlich mit drei Leitungen. Davon sind zwei für die Betriebsspannung bzw. Masseverbindung und eine dritte zur Leitung des Ausgangssignals der jeweiligen Sensorschaltung zum Regler 15. Diese Leitung kann ein der Meßgröße analoges oder im Falle der digitalen Signalverarbeitung im Regler auch ein digitales Signal führen. In diesem Fall wäre in der Sensorschaltung ein Analog-Digital-Wandler vorzuse­hen.Depending on the type of application, it may be advantageous to construct the circuits associated with the individual sensors - hereinafter referred to as sensor circuits - as separate modules 32, 33, 34, which are connected to the controller 15 and the associated sensor 12 by only a few lines. 26, 16 are connected. This arrangement has the advantage that when the arrangement according to the invention is adapted to, for example, different internal combustion engines for which different sensors are required, only one or more of the modules 32, 33, 34 need to be replaced. To connect the respective sensor circuit 32, 33, 34 to the controller 15, which also takes over the supply of the sensor circuits with the operating voltage, is basically carried out with three lines. Two of these are for the operating voltage or ground connection and a third one is used to conduct the output signal of the respective sensor circuit to the controller 15. This line can carry an analogue of the measured variable or, in the case of digital signal processing in the controller, a digital signal. In this case, an analog-to-digital converter would have to be provided in the sensor circuit.

Bei der in Fig. 3 gezeigten Anordnung sind drei Sensoren vorgesehen. Ein Luftmassensensor 12 besteht aus einem ersten temperaturabhängigen Leiter 35 und einem zweiten temperaturabhängigen Vergleichsleiter 36. Beide Leiter sind vom Luftstrom umströmt. Der Leiter 35 wird mit einem von der Sensorschaltung 32 zugeführten Strom auf eine konstante, wesentlich über der Temperatur der Luft liegenden Temperatur aufgeheizt. Die Sensorschaltung 32 beinhaltet eine Reglerschaltung, in welcher über die Temperaturab­hängigkeit des Widerstandswertes des Widerstandes 35 die Temperatur ermittelt und der dem Widerstand 35 zugeführte Strom im Sinne einer Konstanthaltung der Temperatur geregelt wird. Die Größe des Stromes ist dann ein Maß für die Luftmasse. Zur Kompensation des Einflusses der Lufttemperatur ist in der Nähe des Leiters 35 ein Vergleichsleiter angeordnet, welcher jedoch von einem geringen Strom durchflossen wird, so daß er praktisch nicht über die Lufttemperatur hinaus erwärmt wird. Mit der Sensorschaltung 33 ist ein temperaturabhängiger Widerstand 37 verbunden, welcher beispielsweise als Motor bzw. Saugrohrtem­peratursensor 26 dient. Er ist Teil einer Brücken­schaltung, welche im übrigen in der Sensorelektronik 33 angeordnet ist.In the arrangement shown in Fig. 3, three sensors are provided. An air mass sensor 12 consists of a first temperature-dependent conductor 35 and a second temperature-dependent comparison conductor 36. The air flow flows around both conductors. The conductor 35 is heated with a current supplied by the sensor circuit 32 to a constant temperature substantially above the temperature of the air. The sensor circuit 32 contains a regulator circuit in which the temperature is determined via the temperature dependence of the resistance value of the resistor 35 and the current supplied to the resistor 35 is regulated in the sense of keeping the temperature constant. The size of the current is then a measure of the air mass. To compensate for the influence of the air temperature, a comparison conductor is arranged in the vicinity of the conductor 35, but a small current flows through it, so that it is practically not heated above the air temperature. With the sensor circuit 33 a temperature-dependent resistor 37 is connected, which serves, for example, as an engine or intake manifold temperature sensor 26. It is part of a bridge circuit, which is otherwise arranged in the sensor electronics 33.

Schließlich ist die Sensorschaltung 34 mit einem Potentiometer 38, welches als Drosselklappen-Stel­lungsgeber dient, verbunden. In dem Gehäuse ist fer­ner eine an sich bekannte Spannungsstabilisierungs-­Schaltung 39 angeordnet, welche über den Eingang 22 mit dem Bordnetz verbunden ist und für den Regler 15 sowie die Sensorschaltungen 32, 33, 34 eine stabili­sierte Betriebsspannung zur Verfügung stellt. Der Ausgang 40 des Reglers 15 ist mit dem Einspritzven­til 5 (Fig. 1, Fig. 2) verbunden.Finally, the sensor circuit 34 is connected to a potentiometer 38, which serves as a throttle valve position transmitter. In the housing there is also a known voltage stabilization circuit 39 which is connected to the vehicle electrical system via the input 22 and which provides a stabilized operating voltage for the controller 15 and the sensor circuits 32, 33, 34. The output 40 of the controller 15 is connected to the injection valve 5 (FIG. 1, FIG. 2).

In anderen Fällen kann es günstiger sein, die Sensor­schaltungen 32, 33, 34 nicht als separate Bausteine aufzubauen, sondern in den Regler 15 zu integrieren. Dieses hat den Vorteil, daß auch die Löt- bzw. Steck­verbindungen zwischen den Bausteinen 32, 33, 34 und dem Regler 15 entfallen können. Zur Anpassung des Reglers 15 an verschiedene Sensoren wären dann Ände­rungen im Regler 15 selbst erforderlich.In other cases, it may be more favorable not to construct the sensor circuits 32, 33, 34 as separate components, but to integrate them in the controller 15. This has the advantage that the soldering or plug connections between the components 32, 33, 34 and the controller 15 can also be omitted. Changes in the controller 15 itself would then be necessary to adapt the controller 15 to different sensors.
