Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer Zündspulenanordnung für Mehrzylinder-Brennkraftmaschinen nach der Gattung des Oberbegriffs des Anspruchs 1. Eine solche Zündspulenanordnung ist aus der DE 36 10 067 C3 bekannt.The invention relates to an ignition coil arrangement for Multi-cylinder internal combustion engines according to the preamble of the claim 1. Such an ignition coil arrangement is from the DE 36 10 067 C3 known.

Die Zündspulenanordnung besteht aus mehreren, jeweils durch eine Endstufe angesteuerte Spuleneinheiten in der Art von Mehrfachzündspulen. Jede Spuleneinheit setzt sich aus einer Primärspule und einer, an zwei Zündkerzen angeschlossenen Sekundärspule zusammen. Alle Spuleneinheiten sind zu einer baulichen Einheit mit einem gemeinsamen Gehäuse zusammengefaßt. Dadurch ist die Zündspulenanordnung großbauend, so daß unter beengten Einbauverhältnissen im Motorraum einer Brennkraftmaschine der Einbau einer solchen Zündspulenanordnung auf Schwierigkeit stoßen kann.The ignition coil arrangement consists of several, each by an output stage controlled coil units in the manner of Multiple ignition coils. Each coil unit consists of one Primary coil and one connected to two spark plugs Secondary coil together. All coil units are one structural unit combined with a common housing. As a result, the ignition coil arrangement is large, so that under cramped installation conditions in the engine compartment of an internal combustion engine the installation of such an ignition coil arrangement may encounter difficulty.

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße Zündspulenanordnung mit den kennzeichnenden Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, daß die vorerwähnte Unzulänglichkeit in zufriedenstellendem Maß vermieden wird. Dazu weist die Zündspulenanordnung mindestens eine Spuleneinheit als Mehrfachzündspule auf, deren Primärspule und Sekundärspule jeweils geteilt und mechanisch getrennt ausgeführt sind. Je eine Primärteilspule und eine Sekundärteilspule sind zu einer Teilspule zusammengefaßt und mehrere Teilspulen elektrisch in Serie geschaltet.The ignition coil arrangement according to the invention with the characteristic In contrast, features of claim 1 have the advantage that the aforementioned inadequacy is satisfactory Measure is avoided. For this purpose, the ignition coil arrangement at least one coil unit as a multiple ignition coil on, whose primary coil and secondary coil are each divided and are mechanically separated. One primary coil each and a secondary coil are combined to form a coil and several sub-coils electrically connected in series.

Damit besteht die Zündspulenanordnung aus mehreren kleinen Einheiten, von denen jede für sich infolge eines geringen Bauvolumens, insbesondere bei einer Stabkernausführung, auch unter beengten Einbauverhältnissen zu plazieren ist, so daß diese Zündspulenanordnung vielfältig verwendbar ist und in großen Stückzahlen und somit kostengünstig gefertigt werden kann.The ignition coil arrangement thus consists of several small ones Units, each of which is a small unit Construction volume, especially with a rod core design, too to be placed under cramped installation conditions, so that this ignition coil arrangement is versatile and in large quantities and therefore inexpensive to manufacture can.

Durch die Aufteilung jeweils einer Primärspule und der Sekundärspule zu elektrisch in Serie geschalteten, jeweils ein Abschnitt der Primärspule und zugeordneten Sekundärspule enthaltenden Teilspulen ergeben sich zudem noch Materialeinsparungen, da beispielsweise der Eisenkreis der Teilspulen nur noch für ein Teil der Zündspannung ausgelegt sein muß.By dividing a primary coil and a secondary coil to electrically connected in series, one each Section of the primary coil and associated secondary coil partial coils containing material savings, because, for example, the iron circle of the partial coils only needs to be designed for part of the ignition voltage.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Zündspulenanordnung möglich.By the measures listed in the subclaims advantageous developments and improvements in the claim 1 specified ignition coil arrangement possible.

An embodiment of the invention is in the drawing shown and explained in more detail in the figure description. It shows the figure in schematic form the circuit diagram of a Coil unit.

Beschreibung eines AusführungsbeispielsDescription of an embodiment

Eine Zündspulenanordnung für eine Mehrzylinder-Brennkraftmaschine setzt sich aus mehreren gleichartigen Spuleneinheiten 11 in der Art von Mehrfachzündspulen, verwirklicht als Doppelzündspulen, zusammen, von denen eine in der Figur dargestellt ist.An ignition coil assembly for a multi-cylinder internal combustion engine consists of several similar ones Coil units 11 in the manner of multiple ignition coils realized as double ignition coils, one of which is in the figure is shown.

Jede Spuleneinheit 11 enthält eine Primärspule 12 und eine an zwei Zündkerzen 13 angeschlossene Sekundärspule 14 und ist von einem Schaltglied 16 in Form einer Endstufe, hier symbolisiert durch das Schaltzeichen eines Transistors, gesteuert.Each coil unit 11 contains a primary coil 12 and one connected to two spark plugs 13 secondary coil 14 and is of a switching element 16 in the form of an output stage, here symbolized by the circuit symbol of a transistor, controlled.

Sowohl die Primärspule 12 als auch die Sekundärspule 14 sind mechanisch und räumlich getrennt aufgeteilt in zwei Primärteilspulen 17 bzw. zwei Sekundärteilspulen 18. Je eine Primärteilspule 17 und eine Sekundärteilspule 18 ist, zusammen mit einem darin angeordneten Eisenkern 19, zu einer ersten Teilspule 21 bzw. zweiten Teilspule 22 zusammengefaßt. Jede der Teilspulen 21, 22 ist in einem Gehäuse 23 angeordnet.Both the primary coil 12 and the secondary coil 14 are mechanically and spatially separated into two primary coil sections 17 or two secondary section coils 18. One primary section coil each 17 and a secondary coil 18 is together with an iron core 19 arranged therein, to a first one Sub-coil 21 or second sub-coil 22 summarized. Each the partial coils 21, 22 is arranged in a housing 23.

Das jeweils eine Ende der beiden Primärteilspulen ist mit einer gemeinsamen Primär-Verbindungsleitung 24 und das jeweils eine Ende der beiden Sekundärteilspulen 18 ist mit einer gemeinsamen Sekundär-Verbindungsleitung 26 zusammengeführt.One end of each of the two primary coil sections is included a common primary connecting line 24 and each one end of the two secondary part coils 18 is with one common secondary connecting line 26 merged.

Während das jeweils andere Ende der beiden Sekundärteilspulen 18 zu je einer Zündkerze 13 führt, ist das andere Ende der Primärteilspule 17 der ersten Teilspule 21 an den Pluspol einer Stromversorgung des Kraftfahrzeugs und das andere Ende der Primärteilspule 17 der zweiten Teilspule 22 an das mit Massepotential in Verbindung stehende Schaltglied 16 angeschlossen.While the other end of the two secondary section coils 18 leads to a spark plug 13, the other end the primary coil section 17 of the first coil section 21 to the positive pole a power supply to the motor vehicle and the other End of the primary coil section 17 of the second coil section 22 to the switching element 16 connected to ground potential.

Alternativ kann eine Spuleneinheit 11 mit einem Schaltglied 16 auch aus drei oder mehr Primärteilspulen 17 bzw. Sekundärteilspulen 18 bei gleichartigem Aufbau und serieller Zusammenschaltung bestehen.Alternatively, a coil unit 11 with a switching element 16 also from three or more primary section coils 17 or secondary section coils 18 with the same structure and serial interconnection consist.

Durch die mechanisch und räumliche Auftrennung der Spuleneinheiten 11 in Teilspulen 21, 22, die elektrisch in Serie geschaltet sind, ergeben sich kleinbauende Einheiten die auf unter beengten Platzverhältnissen einfach zu plazieren sind.Due to the mechanical and spatial separation of the coil units 11 in partial coils 21, 22, which are electrically in series are connected, there are small units that are easy to place in tight spaces.
