Description

Die Erfindung bezieht sich auf eine Zündeinrichtung für Brennkraftmaschinen, Öl- und Gasbrenner u.dgl., mit einer eine Zündspule aufweisenden Zündspannungsquelle, wobei an die Sekundärseite der Zündspule mindestens eine Entladungsstrecke angeschlossen ist, in der ggf. ein Zündverteiler und mindestens eine Zündkerze vorgesehen sind. Es versteht sich, daß der Zündverteiler bei Mehrzylindermotoren im Zusammenhang mit einer entsprechenden Anzahl von Zündkerzen Anwendung findet. Je nach dem gerade gezündeten Zylinder ergibt sich dann jeweils eine Entladungsstrecke, in der der Zündverteiler und die jewilige Zündkerze vorgesehen sind.The invention relates to an ignition device for internal combustion engines, oil and gas burners and the like, with an ignition voltage source having an ignition coil, at least one discharge path being connected to the secondary side of the ignition coil, in which an ignition distributor and at least one spark plug are optionally provided . It is understood that the ignition distributor is used in multi-cylinder engines in connection with a corresponding number of spark plugs. Depending on the cylinder just ignited, there is then a discharge path in which the distributor and the respective spark plug are provided.

Aus der DE-PS 19 o2 199 ist ein Zündkerzenstecker bekannt, bei dem die Umhüllung, das Hohlelement und das dazwischenliegende Dielektrikum einen Kondensator bilden und bei denen der Kondensator parallel zu den Zündkerzenelektroden derart geschaltet ist, daß in dem Prallelkreis keine Widerstände eingeschlossen sind. Damit, wird die Zündleistung der Zündanlage derart verbessert, daß eine Intensivierung des Zündfunkens stattfindet und es somit eine bessere Verbrennung des Kraftstoff-Luft-Gemisches resultiert. Von dem Kondensator wird allerdings lediglich die Zündkerze überbrückt, so daß sich die anderen, sekundärseitig vorgesehenen Widerstände weiterhin nachteilig auswirk-en.From DE-PS 19 o2 199 a spark plug connector is known in which the sheath, the hollow element and the dielectric in between form a capacitor and in which the capacitor is connected in parallel with the spark plug electrodes in such a way that no resistors are included in the parallel circuit. This improves the ignition performance of the ignition system in such a way that the ignition spark is intensified and the combustion of the fuel-air mixture is thus improved. However, only the spark plug is bridged by the capacitor, so that the other resistances provided on the secondary side continue to have a disadvantageous effect.

Der Erfindung liegt die Aufgabe zugrunde, eine Zündeinrichtung der eingangs beschriebenen Art derart zu verbessern, daß die Verbrennung wirtschaftlicher abläuft und die entstehenden toxischen Abgase reduziert werden.The invention has for its object to improve an ignition device of the type described in such a way that the combustion is more economical and the resulting toxic Exhaust gases are reduced.

Erfindungsgemäß wird dies dadurch erreicht, daß an die Sekundärseite der Zündspule eine den Zündverteiler und die Zündkerzen überbrückende Leitung parallel angeschlossenund in dieser Leitung ein Kondensator angeordnet ist, und daß weder in der Leitung noch in dem parallelen Teil der Entladungsstrecke zusätzliche Widerstände vorgesehen sind. Die Erfindung geht damit von dem Gedanken aus, die gesamte Zündeinrichtung zu verbessern, einen insgesamt höheren Zündstrom an der Zündkerze zur Wirkung zu bringen, und zwar bei vorgegebener Zündspannungsquelle mit Zündspule, um dadurch eine verstärkte Initialzündung des Kraftstoff-Luft-Gemisches zu erzielen. Wesentlich ist, daß sämtliche Unterbrechungsstellen in der Entladungsstrecke, die dort vorgesehen sind, von der Leitung überbrückt werden, also insbesondere der Zündverteiler und die Zündkerze. In dieser Leitung ist dann erfindungsgemäß ein Kondensator angeordnet. Wesentlich ist weiterhin, daß weder in dieser Leitung noch im parallelen Teil der Entladungsstrecke zusätzliche Widerstände vorgesehen sind, wobei unter dem Begriff "zusätzliche Widerstände" solche Widerstände verstanden werden, die zusätzlich zu dem ohnehin einen geringen Widerstand bildenden Zündverteiler und der Zündkerze vorgesehen sein könnten.According to the invention, this is achieved in that a line bridging the ignition distributor and the spark plugs is connected in parallel to the secondary side of the ignition coil and a capacitor is arranged in this line, and that no additional resistances are provided either in the line or in the parallel part of the discharge gap. The invention is therefore based on the idea of improving the entire ignition device, bringing about an overall higher ignition current at the spark plug, specifically with a given ignition voltage source with an ignition coil, in order thereby to achieve an increased initial ignition of the fuel-air mixture. It is essential that all interruption points in the discharge path which are provided there are bridged by the line, in particular the ignition distributor and the spark plug. According to the invention, a capacitor is then arranged in this line. It is also important that additional resistances are not provided in this line or in the parallel part of the discharge gap, the term “additional resistances” being understood to mean those resistances which could be provided in addition to the ignition distributor and the spark plug which form a low resistance anyway.

Die Zündkerzen können zusätzlich durchje eine Umgehungsleitung überrückt sein, in der jeweils ein weiterer Kondensator angeordnet ist. Auf die Weise wird individuell eine höhere Energieeinrichtung an den verschiedenen Überschlagstrecken erreicht. Es versteht sich, daß sowohl die Leitung wie auch die Umgehungsleitungen jeweils-an Masse enden Bzw. mit dem Teil leitend verbunden sind, der mit dem Gehäuse des Zündraumes in Verbindung steht. Dies ist in aller Regel der Motor.The spark plugs can additionally be bridged by a bypass line, in each of which a further capacitor is arranged. In this way, a higher energy facility is achieved individually on the different rollover routes. It goes without saying that both the line and the bypass lines each end at ground or are conductively connected to the part which is connected to the housing of the ignition chamber. This is usually the engine.

In dem parallelen Teil der Entladungsstrecke kann zusätzlich auch eine Nachbrennerzündung, eine Standheizung od. dgl. eingeschaltet sein, also jeweils Einrichtungen, die einer Zündung bedürfen. Es ist dann nicht mehr erforderlich, eine gesonderte Zündanlage für derartige Einrichtungen bereitzustellen. Es kann vielmehr die ohnehin vorhandene Zündanlage einer Brennkraftmaschine hierzu vorteilhaft mitbenutzt werden. Es versteht sich, daß auch eine solche Nachbrennerzündung, eine Standheizung od. dgl. dann von der Leitung mit dem Kondensator überbrückt ist.An afterburner ignition, an auxiliary heater or the like can also be switched on in the parallel part of the discharge path, that is to say devices that require ignition. It is then no longer necessary to provide a separate ignition system for such devices. Rather, the ignition system of an internal combustion engine which is already present can advantageously be used for this purpose. It goes without saying that such an afterburner ignition, auxiliary heater or the like is then bridged by the line with the capacitor.

Zwischen der Sekundärseite der Zündspule und dem Abzweigpunkt der den Kondensator aufweisenden Leitung kann ein Entstörwiderstand angeordnet sein. Wesentlich ist, daß dieser Entstörwiderstand nicht mit überbrückt wird, also nicht in der Leitung und auch nicht in dem parallelen Teil der Entladungsstrecke angeordnet ist.An interference suppression resistor can be arranged between the secondary side of the ignition coil and the branch point of the line having the capacitor. It is essential that this interference suppression resistor is not bridged, that is to say it is not arranged in the line or in the parallel part of the discharge path.

Bei Anwendung von mehreren Kondensatoren bzw. einem gemeinsamen Kondensator in der Leitung und weiteren Kondensatoren für jede einzelne Zündkerze können diese Kondensatoren insgesamt aufeinander abgestimmt sein.When using several capacitors or a common capacitor in the line and further capacitors for each individual spark plug, these capacitors can be coordinated with one another.

Durch die erfindungsgemäße Zündeinrichtung werden in verschiedener Hinsicht Vorteile erreicht. In jedem Falle erfolgt eine Energiestabilisierung an jeder in dem parallelen Teil Entladungsstrecke vorgesehenen Funkenstrecke. Insbesondere erfolgt dies im,Bereich des Zündverteilers. Sein Übergangswiderstand wird ver ringert und dadurch der Energiedurchsatz erhöht. Dies wirkt sich in der Folge auch zugleich bei allen folgenden Funkenstrecken, beispielsweise an der Zündkerze positiv aus. Der Wirkungsgrad der gesamten Zündanlage wird wesentlich erhöht. Diese Erhöhung erstreckt sich auch auf die Wirkung von Funkenstrecken, die sich in einem Nachverbrennungssystem od. dgl. befinden. Die Erfindung ist unabhängig von der Art der Zündspannungsquelle, die in herkömmlicher Bauart oder als elektronische Zündanlage od. dgl. ausgebildet sein kann. Die Anordnung des alle Funkenstrecken in der Entladungsstrecke Überbrückenden Kondensator bringt gleichzeitig eine Entstörung, so daß in den meisten Fällen auf die Anordnung eines Entstörwiderstandes verzichtet werden kann.Advantages are achieved in various respects by the ignition device according to the invention. In any case, energy is stabilized at each spark gap provided in the parallel part of the discharge gap. This takes place in particular in the area of the ignition distributor. Its contact resistance is reduced, thereby increasing the energy throughput. This also has a positive effect on all subsequent spark gaps, for example on the spark plug. The efficiency of the entire ignition system is increased significantly. This increase also extends to the effect of spark gaps that are located in an afterburning system or the like. The invention is independent of the type of ignition voltage source, which can be of conventional design or as an electronic ignition system or the like. The arrangement of the capacitor bridging all spark gaps in the discharge path simultaneously brings interference suppression, so that in most cases the arrangement of an interference suppression resistor can be dispensed with.

In Fig. 1 ist stellvertretend für die Zündspannungsquelle lediglich deren letztes Teil, nämlich die Zündspule 1, dargestellt. Wie ersichtlich, schließt an die Sekundärseite 2 der Zündspule 1 eine Entladungsstrecke 3 an, die letztlich zur Masse 4 führt. In der Entladungsstrecke kann eine Nachbrennerzündung 5 und eine Zündkerze 6 in der gezeigten Weise in Reihe geschaltet vorgesehen sein. Es handelt sich beispielsweise um einen Einzylindermotor mit einer Abgasnachverbrennung. An die Sekundärseite 2 der Zündspule 1 ist nun eine Leitung 7 angeschlossen, die ebenfalls zur Masse 4 führt oder jedenfalls zu dem Gegenpol der Zündkerze 6. In dieser Leitung 7 ist der Kondensator 8 angeordnet, der sämtliche Funkenstrecken in der Entladungsstrecke 3 überbrückt, also die Funkenstrecke der Nachbrenneinrichtung 5 und der Zündkerze 6.In Fig. 1, representative of the ignition voltage source, only its last part, namely the ignition coil 1, is shown. As can be seen, a discharge path 3 connects to the secondary side 2 of the ignition coil 1 and ultimately leads to the ground 4. An afterburner ignition 5 and a spark plug 6 can be provided in series in the manner shown in the discharge path. For example, it is a single-cylinder engine with exhaust gas afterburning. A line 7 is now connected to the secondary side 2 of the ignition coil 1, which also leads to ground 4 or in any case to the opposite pole of the spark plug 6. In this line 7 the capacitor 8 is arranged, which bridges all spark gaps in the discharge gap 3, i.e. the spark gap of the afterburner 5 and the spark plug 6.

Fig. 2 unterscheidet sich von der Schaltung nach Fig. 1 nur dadurch, daß in der Entladungsstrecke3 zusätzlich ein Zündverteiler 9 vorgesehen ist, wie er bei Mehrzylindermotoren angewendet wird. Hier überbrückt die Leitung 7 nicht nur die Nachbrenneinrichtung 5, sondern auch den Zündverteiler 9 und die jeweilige Zündkerze 6. Es handelt sich um ein vereinfachtes Schema eines Vierzylinder- oder eines Sechszylindermotor. Erweiterungsmöglichkeiten sind selbstverständlich denkbar. Die Schaltung gemäß Fig. 2 kann auch dann Anwendung finden, wenn eine Nachbrenneinrichtung 5 nicht vorgesehen ist.Fig. 2 differs from the circuit of Fig. 1 only in that an ignition distributor 9 is also provided in the discharge gap 3, as is used in multi-cylinder engines. Here, the line 7 bridges not only the afterburner 5, but also the ignition distributor 9 and the respective spark plug 6. It is a simplified diagram of a four-cylinder or a six-cylinder engine. Expansion options are of course conceivable. The circuit according to FIG. 2 can also be used when an afterburner 5 is not provided.

Die Schaltung gemäß Fig. 3 ist ähnlich aufgebaut wie die nach Fig. 2. Es ist also wiederum die Entladungsstrecke 3 mit der Nachbrenneinrichtung, dem Zündverteiler 9 und der Zündkerze 6 vorgesehen. Parallel dazu ist die Leitung 7 mit dem Kondensator angeordnet, die vom Abzweigpunkt 1o an der Entladungsstrecke 3 bis zur Masse 4 führt. Zusätzlich ist eine Umgehungsleitung 11 vorgesehen, die von einem Abzweigpunkt 12 zwischen dem Zündverteiler 9 und der Zündkerze 6 ausgeht und ebenfalls zur Masse 4 parallel führt. In dieser Umgehungsleitung 11 ist ein weiterer Kondensator 13 angeordnet. Der Kondensator 13 dient lediglich der Überbrückung der Zündkerze 6. Die Kondensatoren 8 und 13 sind zweckmäßig aufeinander abgestimmt. Sie können beispielsweise gleich ausgebildet sein.The circuit according to FIG. 3 is constructed similarly to that according to FIG. 2. The discharge path 3 with the afterburner, the ignition distributor 9 and the spark plug 6 is therefore again provided. In parallel to this, the line 7 with the capacitor is arranged, which leads from the branch point 10 on the discharge path 3 to the ground 4. In addition, a bypass line 11 is provided, which starts from a branch point 12 between the distributor 9 and the spark plug 6 and also leads to ground 4 in parallel. A further capacitor 13 is arranged in this bypass line 11. The capacitor 13 serves only to bypass the spark plug 6. The capacitors 8 and 13 are expediently matched to one another. For example, they can have the same design.

Fig. 4 zeigt den Schaltplan für einen Vierzylindermotor, dessen Zündanlage zusätzlich noch entstört ist. Es ist hier der Entstörwiderstand 14 vorgesehen, der zwischen der Sekundärseite 2 der Zündspule 1 und dem Abzweigpunkt 1o der Leitung 7 angeordnet ist. Der Zündverteiler 9 ist hier etwas ausführlicher dargestellt. Ebenso ersieht man, daß für jede der vier Zündkerzen 6 ein weiterer Kondensator 13 mit je einer weiteren Umgehungsleitung 11 vorgesehen sind. Eine Nachbrenneinrichtung ist hier beispielsweise nicht vorgesehen.Fig. 4 shows the circuit diagram for a four-cylinder engine, the ignition system is additionally suppressed. The interference suppression resistor 14 is provided here, which is arranged between the secondary side 2 of the ignition coil 1 and the branch point 10 of the line 7. The distributor 9 is shown here in somewhat more detail. It can also be seen that a further capacitor 13, each with a further bypass line 11, is provided for each of the four spark plugs 6. An afterburner is not provided here, for example.

Bei der Zündeinrichtung gemäß Fig. 5 sind sämtliche Funkenstrecken durch die Leitung 7 mit dem Kondensator 8,überbrückt. Zusätzlich ist die Nachbrenneinrichtung 5 mit einer Parallelleitung 15 überbrückt, in der ein weiterer Kondensator 16 angeordnet ist. Es versteht sich, daß die Anlagen gemäß Fig. 3 und 5 auch kombiniert werden können,indem nämlich Umgehungsleitungen 11 und eine Parallelleitung 15 kombiniert werden.In the ignition device according to FIG. 5, all spark gaps are bridged by the line 7 with the capacitor 8. In addition, the afterburner 5 is bridged with a parallel line 15 in which a further capacitor 16 is arranged. It goes without saying that the systems according to FIGS. 3 and 5 can also be combined, namely by combining bypass lines 11 and a parallel line 15.
