Abstract
Description
Die Erfindung geht aus von einem Verfahren zum Steuern der Zündanlage für Brennkraftmaschinen nach der Gattung des Oberbegriffs des Hauptanspruchs. Es ist schon eine Zündanlage zur Erzeugung einer Folgefunkenzündung aus der DE-A- 2340865 bekannt, wobei eine Folgefunkenzündung zum Zündzeitpunkt ausgelöst wird und durch das mehrmalige aufeinanderfolgende Ansteuern der Endstufe bei jedem Abschalten des Zündspulenstroms sekundärseitig ein Zündfunke ausgelöst wird. Bei dieser bekannten Anordnung brennt der Zündfunke bis zum Wiedereinschalten des Primärstromes nicht aus, so daß zum Zeitpunkt des Wiedereinschaltens eine bestimmte Restenergie in der Zündspule enthalten ist. Der Aufladevorgang einer Einzelzündung weist üblicherweise die gleiche Dauer wie der Aufladevorgang der restlichen Einzelzündungen dieser Folgefunkenzündung auf. Das führt unter Umständen dazu, insbesondere wenn Energieverluste beispielsweise im Zündgeschirr oder durch Nebenschlüsse an der Zündkerze auftreten, daß der Aufladevorgang einer Einzelzündung nicht ausreichend ist, um einen Zündfunken auszulösen.The invention relates to a method for controlling the ignition system for internal combustion engines according to the preamble of the main claim. An ignition system for generating a secondary spark ignition is already known from DE-A-2340865, a secondary spark ignition being triggered at the ignition point and an ignition spark being triggered on the secondary side by the repeated successive activation of the output stage each time the ignition coil current is switched off. In this known arrangement, the ignition spark does not burn out until the primary current is switched on again, so that a certain residual energy is contained in the ignition coil at the time of switching on again. The charging process of a single ignition usually has the same duration as the charging process of the remaining individual ignitions of this secondary spark ignition. Under certain circumstances, especially when energy losses occur, for example, in the ignition harness or as a result of shunts on the spark plug, the charging process of a single ignition is not sufficient to trigger an ignition spark.
Das erfindungsgemäße Verfahren mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß die in der Spule verbleibende Restenergie beim Wiedereinschalten an der Spule ermittelt wird, und daraus auf die an der Kerze herrschenden Verhältnisse geschlossen werden kann. So ist es möglich, bei einer zu geringen Restenergie auf einen Nebenschluß an der Kerze zu schließen. Als weiterer Vorteil ist anzusehen, daß über die Auswertung der Restenergie Rückschlüsse über die Gemischbildung möglich sind, so läßt beispielsweise eine zu geringe Restenergie auf ein fettes Gemisch und eine sehr hohe Restenergie auf ein mageres Gemisch schließen. Vor allem im Startfall bietet es die Möglichkeit, die Gemischbildung zu verbessern. Letztendlich sei noch erwähnt, daß durch das Erkennen eines Nebenschlusses der Abschaltstrom für die darauffolgende Einzelzündung der Folgefunkenzündung erhöht werden kann, so daß sich die Zündkerze unter Umständen selbst freibrennt und der Nebenschluß beseitigt wird.The method according to the invention with the characterizing features of the main claim has the advantage that the residual energy remaining in the coil is determined when the coil is switched on again, and the conditions prevailing on the candle can be deduced therefrom. So it is possible to conclude a shunt on the candle if the residual energy is too low. Another advantage is the fact that conclusions about the mixture formation are possible by evaluating the residual energy, for example, an insufficient residual energy indicates a rich mixture and a very high residual energy indicates a lean mixture. Especially when starting, it offers the opportunity to improve the mixture formation. Finally, it should also be mentioned that by recognizing a shunt, the cut-off current for the subsequent individual ignition of the subsequent spark ignition can be increased, so that the spark plug burns free under certain circumstances and the shunt is eliminated.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Hauptanspruch angegebenen verfahrens möglich. Besonders vorteilhaft ist, daß das Steuergerät, nach einem Vergleich des erfaßten Primäranfangsstroms mit einem vorgebbaren Referenzwert, wobei dieser Referenzwert in Abhängigkeit vom Betriebszustand und Motortyp vorgebbar ist, bei einem kleineren Primäranfangsstrom als der Referenzwert den Abschaltstrom für die darauffolgende Einzelzündung durch ein vom Steuergerät zu beeinflussendes Schaltglied erhöht. Hierbei ist es besonders vorteilhaft, daß die Erhöhung des Abschaltstromes durch die Erhöhung des Basisstromes der Endstufe möglich ist, wenn die Endstufe dafür ausgelegt ist und sich noch nicht im voll durchgesteuerten Zustand (Strombegrenzung) befindet, da sonst nur über eine Erhöhung der Schließzeit der Endstufe der Abschaltstrom erhöht werden kann. Auf eine höhere Versorgungsspannung kann in diesem Fall verzichtet werden. Letztendlich sei als Vorteil erwähnt, daß die Erhöhung des Abschaltstromes der darauffolgenden Einzelzündung durch die Verlängerung der Schließzeit für diese Einzelzündung erhöht werden kann, wenn die Endstufe noch nicht den Stromwert der Strombegrenzung erreicht hat, d.h. durch eine Erhöhung der Schließzeit der Strom noch ansteigen kann. Hierbei ist weder eine Veränderung der Versorgungsspannung noch des Steuersignals für die Endstufe notwendig. Die Erhöhung des Primärabschaltstromes kann beliebig nur für die darauffolgende Einzelzündung oder für mehrere Einzelzündungen erfolgen, wobei die Auswertung des Primäranfangsstromes im Steuergerät ausschlaggebend ist.Advantageous further developments and improvements of the method specified in the main claim are possible through the measures listed in the subclaims. It is particularly advantageous that the control unit, after a comparison of the detected primary initial current with a predeterminable reference value, which reference value can be predefined as a function of the operating state and engine type, with a smaller primary initial current than the reference value, the switch-off current for the subsequent individual ignition by one to be influenced by the control unit Switching element increased. It is particularly advantageous here that the switch-off current can be increased by increasing the base current of the output stage if the output stage is designed for it and is not yet in the fully controlled state (current limitation), since otherwise only by increasing the closing time of the output stage the cut-off current increases can be. In this case, a higher supply voltage can be dispensed with. Ultimately, it should be mentioned as an advantage that the increase in the switch-off current of the subsequent individual ignition can be increased by extending the closing time for this individual ignition if the output stage has not yet reached the current limit value, that is to say the current can increase by increasing the closing time. It is not necessary to change the supply voltage or the control signal for the output stage. The primary cut-off current can be increased arbitrarily only for the subsequent individual ignition or for several individual ignitions, the evaluation of the primary initial current in the control unit being decisive.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen Figur 1 den Prinzipaufbau einer Zündanlage einer nicht dargestellten Brennkraftmaschine, Figur 2 einen Programmablauf zur Erfassung und Auswertung der Größe des Primäranfangsstromes und Figur 3 eine Folgefunkenzündung.An embodiment of the invention is shown in the drawing and explained in more detail in the following description. FIG. 1 shows the basic structure of an ignition system of an internal combustion engine (not shown), FIG. 2 shows a program sequence for detecting and evaluating the size of the primary initial current, and FIG. 3 shows a secondary spark ignition.
Figur 1 zeigt den Prinzipaufbau einer Zündanlage mit einer Zündspule 1 bestehend aus Primärwicklung 2 und Sekundärwicklung 3. Die Primärwicklung 2 ist einerseits an die Versorgungsspannung UB angeschlossen und andererseits über die Kollektor-Emitter-Strecke eines Zündtransistors 4 und einen Widerstand 5 mit Masse verbunden. Die Sekundärwicklung 3 ist einerseits direkt mit Masse verbunden und andererseits über eine Verbindung 6 beispielsweise mit einer nicht dargestellten Zündkerze oder einem ebenfalls nicht dargestellten Verteiler verbunden. Denkbar wäre auch eine Doppelfunkenspule, bei welcher auf jeder Seite der Sekundärwicklung eine Zündkerze angeschlossen ist. Die Zündanlage weist weiterhin ein Steuergerät 7 auf, welches verschiedene Betriebsparameter wie z.B. Drehzahl, Motorlast, Versorgungsspannung als Eingangsgrößen 8 erfaßt. Vom Ausgang des Steuergeräts 7 führt weiterhin eine Verbindung 14 zur Basis des Zündtransistors 4, so daß vom Steuergerät der Primärstrom durch entsprechende Steuersignale an den Zündtransistor ein- und ausgeschaltet werden kann. Aus dem Primärzweig führt ein Abgriff mit einer Verbindung 9 zum Steuergerät, womit im Steuergerät 7 jeweils der Primärstrom Ip über den Spannungsabfall am Widerstand im Primärstromkreis erfaßt wird.Figure 1 shows the basic structure of an ignition system with an ignition coil 1 consisting of primary winding 2 and secondary winding 3. The primary winding 2 is connected on the one hand to the supply voltage U B and on the other hand connected to ground via the collector-emitter path of an ignition transistor 4 and a
Figur 2 zeigt einen vereinfachten Programmablauf zur Erfassung und Auswertung des Primäranfangsstromes einer Einzelzündung EZ aus einer Folgefunkenzündung FFZ. Der Primäranfangsstrom Ipa wird in einem Arbeitsschritt 10 vom Steuergerät 7 erfaßt. In einer anschließenden Abfrage 11 wird der erfaßte Primäranfangsstrom Ipa mit einem vorgebbaren Referenzwert IG verglichen, d.h. es wird geprüft Ipa IG. Wird diese Abfrage mit nein beantwortet, so führt der Ausgang zum Arbeitsschritt 12, d.h. das Steuergerät wird den Abschaltstrom Ipe für die darauffolgende Einzelzündung EZ beispielsweise durch Erhöhung des Basisstroms für den Zündtransistor 4 erhöhen. Anschließend wird im Arbeitsschritt 13, zu welchem auch der Ja-Ausgang der Abfrage 11 führt, der Primäranfangsstrom Ipa der darauffolgenden Einzelzündung EZ erfaßt und ausgewertet.FIG. 2 shows a simplified program sequence for recording and evaluating the primary initial current of a single ignition EZ from a subsequent spark ignition FFZ. The primary initial current I pa is detected in a
Figur 3 zeigt die aus Einzelzündungen EZ bestehende Folgefunkenzündung FFZ einer Zündspule. Hierbei ist der Primärstrom Ip über die Zeit bzw. über den Kurbelwellenwinkel dargestellt, wobei nur der Teil des Kurbelwellenwinkels bzw. der Zeit t herausgegriffen wurde, in welchem die Einzelzündungen EZ der Folgefunkenzündung FFZ schematisch dargestellt sind. Der Punkt 15 symbolisiert den vom Steuergerät 7 berechneten Zündzeitpunkt der Brennkraftmaschine und der Punkt 16 stellt den Punkt dar, bis zu welchem Einzelzündungen ausgelöst werden können, ohne daß die Gefahr besteht, daß die Zündung durch das Drehen des Verteilerfingers bereits im darauffolgenden Zylinder stattfindet bzw. ohne daß bei ruhender Verteilung die Zündung im Auspuff- bzw. Einlaßtakt stattfindet, was zu einer Beschädigung des Saugrohrs o.ä. führt. Die Einzelzündungen werden in der Figur 3 mit EZ1, EZ2, EZ3 bezeichnet. Bei der Einzelzündung EZ3 ist zu erkennen, daß der Primäranfangsstrom Ipa deutlich unter dem vorgegebenen Referenzwert IG liegt. Wird nun der Basisstroms des Zündtransistors in gleicher Höhe und Dauer wie bei den anderen Einzelzündungen EZ, wo der Primäranfangsstrom Ipa den Referenzwert IG erreicht, beibehalten, so würde das zu der Kurve a führen, das hieße, daß die Abschaltenergie für den Zündfunken unter Umständen nicht ausreicht. Deshalb wird vom Steuergerät dafür gesorgt, daß der Abschaltstrom in der Primärwicklung 2 erhöht wird. Die strichpunktierte Linie b zeigt den Kurvenverlauf des Primärstromes, wie er bei einem erhöhten Basisstrom des Zündtransistors 4 auftritt. Es ist deutlich zu erkennen, daß der Abschaltstrom Ipe - und damit die Energie für den Zündfunken größer ist als für die vorherigen Einzelzündungen. Dadurch ist unter Umständen ein Freibrennen der Zündkerze ermöglicht. Die gestrichelte Linie c zeigt den Kurvenverlauf, wie er bei einer verlängerten Schließzeit für die Einzelzündung mit zu geringem Primäranfangsstrom Ipa auftritt, auch hierbei wird die gespeicherte Energie in der Zündspule erhöht, so daß der Abschaltstrom Ipe höher liegt und gegebenenfalls ein Freibrennen der Kerze ermöglicht.FIG. 3 shows the subsequent spark ignition FFZ of an ignition coil consisting of individual ignitions EZ. Here, the primary current I p is shown over time or over the crankshaft angle, only the part of the crankshaft angle or time t was singled out in which the individual ignitions EZ of the secondary spark ignition FFZ are shown schematically. The
Über eine Erfassung des Primäranfangsstromes können ebenfalls Aussagen über die Gemischzusammensetzung im Zylinder gemacht werden, so daß ein erhöhter Primäranfangsstrom auf ein eher mageres Gemisch und ein niedriger Primäranfangsstrom auf ein fettes Gemisch schließen läßt, was dann bei der Ansteuerung der Einspritzventile für den Einspritzvorgang für die darauffolgende Zündung berücksichtigt werden kann.By recording the primary initial flow, statements can also be made about the mixture composition in the cylinder, so that an increased primary initial flow indicates a rather lean mixture and a lower primary initial flow indicates a rich mixture, which then results in the control of the injection valves for the injection process for the subsequent one Ignition can be taken into account.
