Description
Methode und System zur Kontrolle der Zündfun enfrequenz eines Vielfachfunkenzündsyste s Method and system for checking the spark frequency of a multiple spark ignition system
Die Erfindung richtet sich auf ein Verfahren und eine Ein¬ richtung zur Optimierung der Verbrennung eines Kraftstoff- Luftgemisches, insbesondere zum Einsatz bei Verbrennungs¬ motoren.The invention relates to a method and a device for optimizing the combustion of a fuel-air mixture, in particular for use in internal combustion engines.
Bei modernen Verbrennungsmotoren ist man bemüht, die Ver¬ brennung des Kraftstoffes zu optimieren, wobei ei-ne Entzün¬ dung durch einen einzigen Zündfunken in Gang gesetzt wird. Die Weiterverbrennung erfolgt spontan, ohne daß eine Ein¬ wirkung erfolgt.In modern internal combustion engines, efforts are made to optimize the combustion of the fuel, ignition being triggered by a single ignition spark. The further combustion takes place spontaneously without any effect.
Es ist dabei bekannt. Form und Material der Verbrennungs¬ kammern zu ändern, den Druck im Verbrennungsraum zu verän¬ dern, ggf. den Brennstoff einzustäuben oder andere Maßnah¬ men vorzunehmen. Hierzu gehört die Druckaufladung durch Turbolader, die Anzahl der Zylinder, ebenso wie Zusätze zum Brennstoff, wie Wasser, Ozon, Wasserstoff, aromatische Koh¬ lenstoffe und dergl. mehr.It is well known. To change the shape and material of the combustion chambers, to change the pressure in the combustion chamber, to dust the fuel if necessary, or to take other measures. This includes pressure charging by means of a turbocharger, the number of cylinders, and also additives to the fuel, such as water, ozone, hydrogen, aromatic carbons and the like.
Es ist bekannt, Kraftstoff-Luftgemische unter Druck durch Zündung zu verbrennen, wobei die Entzündung des Gemisches aufgrund der Übertragung von Hochfrequenzimpulsen auf Elek-
troden bewirkt wird. Die Elektroden sind dabei an eine Zündwicklung einer Zündspule angeschlossen (SU-U-879 008).It is known to burn fuel-air mixtures under pressure by ignition, the ignition of the mixture due to the transmission of high-frequency pulses to elec- treading is effected. The electrodes are connected to an ignition coil of an ignition coil (SU-U-879 008).
Darüber hinaus ist beispielsweise aus der US 4 522 185 ein Zündsystem bekannt, bei dem sich in einem Elektrodenzwi¬ schenraum Hochfrequenz-Entspannungsimpulse bilden, wobei dort eine Stromquelle, eine Zündspule und elektronische Schalter, die mit der Primärwicklung der Zündspule verbun¬ den sind, ein Impulsgenerator, dessen Ausgang mit dem elek¬ tronischen Schalter verbunden ist, und mindestens,eine Zündkerze vorgesehen sind.Furthermore, an ignition system is known, for example, from US Pat. No. 4,522,185, in which high-frequency relaxation pulses form in an electrode interspace, with a current source, an ignition coil and electronic switches connected to the primary winding of the ignition coil Pulse generator, the output of which is connected to the electronic switch, and at least one spark plug are provided.
Der Nachteil der bekannten Lösungen besteht insbesondere darin, daß damit keine genügend vollständige Verbrennung der Kraftstoffe bewirkt wird, so daß es zu keiner an sich gewünschten Verminderung der Schadstoffe in den Verbren¬ nungsabgasen kommt, insbesondere ergibt sich keine Vermin¬ derung der Toxidität der Verbrennungsprodukte, da bei der Bildung der Hochfrequenzimpulse die Veränderung der Kraft- stoff-/Luft-/Gemischparameter während des Verbrennungspro¬ zesses nicht in ausreichender Weise berücksichtigt werden.The disadvantage of the known solutions is, in particular, that it does not sufficiently combust the fuels so that there is no inherently desired reduction in the pollutants in the combustion exhaust gases, in particular there is no reduction in the toxicity of the combustion products, since the changes in the fuel / air / mixture parameters during the combustion process are not sufficiently taken into account in the formation of the high-frequency pulses.
Aufgabe der Erfindung ist die Schaffung einer Lösung, mit der verfahrensmäßig und einrichtungsmäßig eine Optimierung des Verbrennungsprozesses, d.h. eine höhere Wirksamkeit und
Vollständigkeit der Kraftstoffverbrennung und damit eine Vermeidung toxischer Verbrennungsprodukte erreicht wird.The object of the invention is to provide a solution with which the combustion and process optimization of the combustion process, ie a higher effectiveness and Completeness of fuel combustion and thus avoidance of toxic combustion products is achieved.
Bei einem Verfahren der eingangs bezeichneten Art wird die¬ se Aufgabe gemäß der Erfindung dadurch gelöst, daß die Zün¬ dung durch Hochfrequenz-Spannungsimpulse auf Elektroden be¬ wirkt wird, welche an die Sekundärwicklung angeschlossen sind, wobei im Verlaufe der Verbrennung des Kraftstoff- Luftgemisches die Frequenz der Spannungsimpulse in Abhän¬ gigkeit von der Stromstärke in der Sekundärwicklung der Zündspule variiert wird.In a method of the type described at the outset, this object is achieved according to the invention in that the ignition is effected by high-frequency voltage pulses on electrodes which are connected to the secondary winding, the combustion of the air-fuel mixture taking place the frequency of the voltage pulses is varied as a function of the current strength in the secondary winding of the ignition coil.
Die Erfindung greift erstmalig aktiv in die Verbrennung ein, indem sie auch Zündimpulse abgibt, wenn die Verbren¬ nung bereits erstmalig gezündet wurde.For the first time, the invention actively intervenes in combustion by also emitting ignition pulses when the combustion has already been ignited for the first time.
Einrichtungsmäßig wird die gestellte Aufgabe dadurch ge¬ löst, daß das Zündsystem eine Stromquelle, eine Zündspule, einen elektronischen Schalter, welcher mit der Primärwick¬ lung der Zündspule verbunden ist, einen Impulsgenerator, dessen Ausgang mit dem elektronischen Schalter verbunden ist und mindestens eine Zündkerze enthält, sich dadurch auszeichnet, daß ein Feedback-Signalformer vorgesehen ist, dessen Eingang mit dem Ausgang der Zündspule an dem elek¬ tronischen Schalter verbunden ist und dessen Ausgang mit dem zweiten Ausgang des Impulsgenerators verbunden ist.
Mit der oben angegebenen Verfahrensweise und der entspre¬ chenden Einrichtung läßt sich eine automatische Steuerung des Prozesses der Kraftstoff-Luftgemischentzündung errei¬ chen, was zu einer gleichmäßigen Verbrennung und der Opti¬ mierung der Geschwindigkeit der chemischen Reaktionen führt. Dies bewirkt damit eine erhöhende Effektivität des Verbrennungsprozesses und der Vollständigkeit der Verbren¬ nung mit den damit verbundenen Vorteilen, daß schädliche Verbrennungsprodukte entfallen.In terms of equipment, the object is achieved in that the ignition system has a power source, an ignition coil, an electronic switch which is connected to the primary winding of the ignition coil, a pulse generator, the output of which is connected to the electronic switch and contains at least one spark plug , characterized in that a feedback signal shaper is provided, the input of which is connected to the output of the ignition coil at the electronic switch and the output of which is connected to the second output of the pulse generator. With the above-mentioned procedure and the corresponding device, an automatic control of the process of fuel-air mixture ignition can be achieved, which leads to a uniform combustion and the optimization of the speed of the chemical reactions. This thus increases the effectiveness of the combustion process and the completeness of the combustion, with the associated advantages that harmful combustion products are eliminated.
Weitere Merkmale, Einzelheiten und Vorteile der Erfindung ergeben sich aufgrund der nachfolgenden Beschreibung sowie anhand der Zeichnung, die in der Figur einen Schaltplan der Zündeinrichtung nach der Erfindung zeigt.Further features, details and advantages of the invention result from the following description and from the drawing, which shows a circuit diagram of the ignition device according to the invention in the figure.
Das erfindungsgemäße Zündsystem enthält die Stromquelle 1, eine Zündspule 2, einen elektronischen Schalter 3, der mit der Primärwicklung der Zündspule 2 verbunden ist, einen Im¬ pulsgenerator 4, dessen Ausgang mit dem elektronischen Schalter 3 verbunden ist, einen Zündmomentenformer 5, der mit dem ersten Eingang des Impulsgenerators 4 verbunden ist sowie einen Feedbacksignalformer 6 und eine Zündkerze 7.The ignition system according to the invention contains the current source 1, an ignition coil 2, an electronic switch 3, which is connected to the primary winding of the ignition coil 2, a pulse generator 4, the output of which is connected to the electronic switch 3, an ignition torque former 5, which is connected to the is connected to the first input of the pulse generator 4 and a feedback signal shaper 6 and a spark plug 7.
Der Feedbacksignalformer 6 ist mit seinem Eingang mit dem Anschlußpunkt der Zündspule 2 am elektronischen Schalter 3
verbunden und dessen Ausgang wiederum mit dem zweiten Ein¬ gang des Impulsgenerators 4. Die Zündkerze 7 ist mit der Sekundärwicklung der Zündspule 2 verbunden. Der oben er¬ wähnte Signalformer 5 kann beispielsweise in Form von nach¬ einander geschaltetem Widerstand und Kondensator ausgeführt sein.The feedback signal shaper 6 has its input connected to the ignition coil 2 at the electronic switch 3 connected and its output in turn to the second input of the pulse generator 4. The spark plug 7 is connected to the secondary winding of the ignition coil 2. The above-mentioned signal shaper 5 can be designed, for example, in the form of a resistor and capacitor connected in series.
Die oben beschriebene Zündeinrichtung arbeitet wie folgt:The ignition device described above works as follows:
Der Zündmomentenformer 5 setzt synchron zur Motor^irehzahl (wobei der Motor in der Zeichnung nicht wiedergegeben ist), den Impulsgenerator 4 in Tätigkeit, und zwar für einen Zeitabschnitt, der umgekehrt proportional der Motordrehzahl ist. Der Impulsgenerator 4 formt Impulse, die den elektri¬ schen Schalter 3 in Tätigkeit setzen, der den elektrischen Strom in der Primärwicklung der Zündspule 2 mit der Impuls¬ folge-Frequenz koppelt. Damit werden in der Sekundärwick¬ lung der Zündspule Hochfrequenzimpulse erzeugt, die zur elektrischen Entladung zwischen den Elektroden der Zünd¬ kerze 7 führen.The ignition torque shaper 5 sets the pulse generator 4 in operation synchronously with the engine speed (the engine is not shown in the drawing), for a period of time which is inversely proportional to the engine speed. The pulse generator 4 forms pulses which activate the electrical switch 3, which couples the electrical current in the primary winding of the ignition coil 2 with the pulse sequence frequency. High-frequency pulses are thus generated in the secondary winding of the ignition coil, which lead to electrical discharge between the electrodes of the spark plug 7.
Infolge der Wechselwirkung von Brennstoffplasma mit dem elektromagnetischen Feld in der Umgebung der Zündkerzen¬ elektroden verändern sich die Frequenzparameter des Sekun¬ därstromkreises der Zündspule, was seinerseits eine Strom¬ veränderung in der sekundären und primären Wicklung der
Zündspule auslöst. Die Stärke des Stromes, der durch die Veränderung der Parameter des Brennstoffes in der Umgebung der Zündkerzenelektroden entsteht, wird nach dem Feedback¬ signalformer 6 in ein Leitsignal umgeformt, welches die Frequenz der vom Impulsgenerator erzeugten Impulse korri¬ giert, in Folge davon auch die Frequenz der elektronischen Entladung auf der Zündkerze 7.
As a result of the interaction of fuel plasma with the electromagnetic field in the vicinity of the spark plug electrodes, the frequency parameters of the secondary circuit of the ignition coil change, which in turn causes a change in current in the secondary and primary winding of the Ignition coil triggers. The strength of the current, which arises from the change in the parameters of the fuel in the vicinity of the spark plug electrodes, is converted into a control signal after the feedback signal former 6, which corrects the frequency of the pulses generated by the pulse generator, and consequently also the frequency the electronic discharge on the spark plug 7.
