Definitions
- the invention is based on an ignition system according to the preamble of the main claim.
- Such an ignition system is already known (according to FIG. 3 of DE-AS 23 39 784), but it can happen that if one of the diodes is damaged and no longer has a blocking effect, the spark plug lying in series in the wrong place When an ignition spark is generated that does not exclude damage to the internal combustion engine.
- US-A-4,411,247 also shows and describes a distributorless ignition system, diodes being arranged between the ignition coil and spark plugs, so that depending on the polarity of the ignition pulse, only the spark plugs ignite, the diode of which has the corresponding polarity.
- the ignition system shown schematically in the drawing is intended for an internal combustion engine (not shown) of a motor vehicle (also not shown).
- This ignition system is fed from a direct current source 1, which can be the battery of the motor vehicle.
- a line 2 connected to ground starts from the negative pole and a supply line 4 containing an operating switch (ignition switch) 3 starts from the positive pole.
- the supply line 4 leads to a middle tap 5, from which a primary winding section 6 and a primary winding section 7 originate.
- the primary winding sections 6, 7 sit on an iron core 8 and form an ignition coil 10 with a secondary winding 9 which is also located on the iron core 8.
- the free connection of the primary winding section 6 is connected to the anode of a blocking diode 11, the cathode of which is applied to the collector with its emitter the ground line 2 lying transistor 12 is connected.
- the free connection of the primary winding section 7 is connected to the anode of a blocking diode 13, the cathode of which is connected to the collector of a transistor 14 with its emitter connected to the ground line 2.
- the base of transistor 12 and the base of transistor 14 alternately receive switch-on pulses 15, 16.

Description
Die Erfindung geht aus von einer Zündanlage nach dem Oberbegriff des Hauptranspruches. Es ist (nach Figur 3 der DE-AS 23 39 784) bereits eine solche Zündanlage bekannt, bei der es jedoch vorkommen kann, daß, wenn eine der Dioden beschädigt ist und keine Sperrwirkung mehr hat, an der in Reihe dazu liegenden Zündkerze im falschen Zeitpunkt ein Zündfunke erzeugt wird, der Schaden an der Brennkraftmaschine nicht ausschließt.The invention is based on an ignition system according to the preamble of the main claim. Such an ignition system is already known (according to FIG. 3 of DE-AS 23 39 784), but it can happen that if one of the diodes is damaged and no longer has a blocking effect, the spark plug lying in series in the wrong place When an ignition spark is generated that does not exclude damage to the internal combustion engine.
Aus der DE-A-3 108 635 ist ein verteilerloses Zündsystem mit Überspannungsabsorber bekannt geworden, bei dem Zenerdioden parallel zu den Zündkerze gegen Masse geschaltet sind. Hierbei handelt es sich um ein Zweizylinder-System, bei dem zwei Zündkerzen an eine Zündspule angeschlossen sind. Die Zenerdioden sind nun zo geschaltet, daß jeweils eine Zenerdiode zusammen mit der Sekundärseite der Zündspule und der anderen Zündkerze einen Zündkreis bildet. Tritt nun bei einer Diode ein Kurzschluß auf, kann dies zur Zerstörung des Zündsystems führen. Die US-A-4,411,247 zeigt und beschreibt ebenfalls ein verteilerloses Zündsystem, wobei zwischen Zündspule und Züdkerzen Dioden angeordnet sind, so daß abhängig von der Polarität des Zündimpulses lediglich die Zündkerzen zünden, deren Diode die entsprechende Polarität aufweist.From DE-A-3 108 635 a distributorless ignition system with surge absorber has become known, in which Zener diodes are connected in parallel with the spark plug to ground. This is a two-cylinder system in which two spark plugs are connected to an ignition coil. The Zener diodes are now zo switched so that a Zener diode forms an ignition circuit together with the secondary side of the ignition coil and the other spark plug. If a short circuit occurs with a diode, this can lead to the destruction of the ignition system. US-A-4,411,247 also shows and describes a distributorless ignition system, diodes being arranged between the ignition coil and spark plugs, so that depending on the polarity of the ignition pulse, only the spark plugs ignite, the diode of which has the corresponding polarity.
Bei der erfindungsgemäßen Zündanlage wird durch Anwendung der kennzeichnenden Maßnahmen des Hauptanspruches der vorerwähnte Nachteil vermieden.In the ignition system according to the invention, the aforementioned disadvantage is avoided by applying the characterizing measures of the main claim.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert.An embodiment of the invention is shown in the drawing and explained in more detail in the following description.
Die in der Zeichnung schaltungsmäßig gezeigte Zündanlage soll für eine nicht dargestellte Brennkraftmaschine eines ebenfalls nicht dargestellten Kraftfahrzeuges bestimmt sein. Diese Zündanlage wird aus einer Gleichstromquelle 1 gespeist, welche die Batterie des Kraftfahrzeuges sein kann. An der Stromquelle 1 geht von dem Minuspol eine mit Masse verbundene Leitung 2 und von dem Pluspol eine einen Betriebsschalter (Zündschalter) 3 enthaltende Versorgungsleitung 4 aus. Die Versorgungsleitung 4 führt zu einer mittleren Anzapfung 5, von der ein Primärwicklungsabschnitt 6 und ein Primärwicklungsabschnitt 7 ausgeht. Die Primärwicklungsabschnitte 6, 7 sitzen auf einem Eisenkern 8 und bilden mit einer ebenfalls auf dem Eisenkern 8 sitzenden Sekundärwicklung 9 eine Zündspule 10. Der freie Anschluß des Primärwicklungsabschnittes 6 liegt an der Anode einer Blockierdiode 11, deren Kathode an den Kollektor eines mit seinem Emitter an der Masseleitung 2 liegenden Transistors 12 angeschlossen ist. Ebenso liegt der freie Anschluß des Primärwicklungsabschnittes 7 an der Anode einer Blockierdiode 13, deren Kathode an den Kollektor eines mit seinem Emitter an der Masseleitung 2 liegenden Transistors 14 angeschlossen ist. Die Basis des Transistors 12 und die Basis des Transistors 14 erhalten abwechselnd Einschaltimpulse 15, 16.The ignition system shown schematically in the drawing is intended for an internal combustion engine (not shown) of a motor vehicle (also not shown). This ignition system is fed from a direct current source 1, which can be the battery of the motor vehicle. At the current source 1, a line 2 connected to ground starts from the negative pole and a supply line 4 containing an operating switch (ignition switch) 3 starts from the positive pole. The supply line 4 leads to a middle tap 5, from which a
Der eine Anschluß 17 der Sekundärwicklung 9 ist an die Anode einer Diode 18 und an die Kathode einer Diode 19 angeschlossen. Dabei hat die Kathode der Diode 18 über eine Zündkerze 20 und die Anode der Diode 19 über eine Zündkerze 21 mit der Masseleitung 2 Verbindung. Der Zündkerze 20 ist eine mit der Anode an der Masseleitung 2 liegende Diode 22 parallel geschaltet, während die Zündkerze 21 eine Diode 23 im Nebenschluß ist, die an ihrer Kathode mit der Masseleitung 2 verbunden ist. Der andere Anschluß 24 der Sekundärwicklung 9 ist sowohl an die Anode einer Diode 25 als auch an die Kathode einer Diode 26 angeschlossen. Dabei hat die Diode 25 an ihrer Kathode über eine Zündkerze 27 und die Diode 26 an ihrer Anode über eine Zündkerze 28 mit der Masseleitung 2 Verbindung. Der Zündkerze 27 ist eine mit der Anode an der Masseleitung 2 liegende Diode 29 parallel geschaltet, während die Zündkerze 28 eine Diode 30 in ihrem Nebenschluß hat, deren Kathode mit der Masseleitung 2 verbunden ist.One terminal 17 of the secondary winding 9 is connected to the anode of a
Die soeben beschriebene Zündanlage hat folgende Wirkungsweise:The ignition system just described works as follows:
Sobald der Betriebsschalter 3 geschlossen wird, ist die Anlage funktionsbereit. Es sei jetzt untersellt, daß jetzt der Einschaltimpuls 15 wirksam ist, woraufhin der Primärwicklungsabschnitt 6 durch den Transistor 12 ein- und ausgeschaltet wird. Das Ausschalten des Primärwicklungsabschnittes 6 soll in der Sekundärwicklung 9 einen Hochspannungsstoß zur Folge haben, bei dem der Anschluß 17 positiv und der Anschluß 24 negativ ist. Dieser Hochspannungsstoß wird an den Zündkerzen 20, 28 einen Zündfunken zur Folge haben, während eine Wirkung auf die Zündkerzen 21, 28 durch die Dioden 19, 26 blockiert wird.As soon as the operating switch 3 is closed, the system is ready for operation. It should now be noted that the switch-on
Kommt dann der Einschaltimpuls 16 zur Wirkung, so wird der Primärwicklungsabschnitt 7 durch den Transistor 14 ein- und ausgeschaltet, wobei jetzt in der Sekundärwicklung 9 ein Hochspannungsstoß auftreten soll, bei dem der Anschluß 24 positiv und der Anschluß 17 negativ wird. Somit werden nun an den Zündkerzen 21, 27 Zündfunken auftreten, während durch die Dioden 18, 26 Zündfunken an den Zündkerzen 20, 28 verhindert werden.If the switch-on
Für den Fall, daß die Dioden 22, 23, 29, 30 nicht vorhanden wären und zum Beispiel die Diode 26 so beschädigt wäre, daß sie nicht mehr sperren könnte, könnte in den zuletzt geschlilderten Funktionsablauf auch ein Zündfunke an der Zündkerze 28 auftreten. Dieser Zündfunke würde bei einem 4-Takt-Reihenmotor mit dem Ansaughub im zugeordneten Zylinder zusammenfallen, wodurch leicht eine Explosion ausgelöst und der Brennkraftmaschine Schaden zugefügt werden könnte. Durch Anwendung der Dioden 22, 23, 29, 30 soll diese Unsicherheit beseitigt werden.In the event that the
