Die Erfindung betrifft ein Verfahren zum Betreiben einer fremdgezündeten Brennkraftmaschine,, wobei in zumindest einem Motorbetriebsbereich zur Erhöhung der Brennraumtemperatur der Zündzeitpunkt zumindest einer Zündeinrichtung vorverstellt wird.The invention relates to a method for operating a spark-ignited internal combustion engine, wherein in at least one engine operating range to increase the combustion chamber temperature, the ignition timing of at least one ignition device is pre-adjusted.
Emissionsgrenzwerte, insbesondere für leichte Straßenkraftfahrzeuge, werden durch gesetzliche Auflagen, zum Beispiel durch die Euro-6-Norm, sehr streng festgelegt, vor allem hinsichtlich der Partikel- und Stickoxidemissionen. Diese Auflagen zielen unter anderem darauf ab, die Partikelanzahl in den Fahrzeugemissionen deutlich zu reduzieren.Emission limit values, in particular for light road vehicles, are set very stringently by statutory requirements, for example by the Euro 6 standard, especially with regard to particulate and nitrogen oxide emissions. These requirements are aimed, among other things, at significantly reducing the number of particles in vehicle emissions.
Der Katalysatorheizbetrieb dient dazu, den Katalysator möglichst rasch auf die Anspringtemperatur (Light-Off-Temperatur) zu bringen. Es sind verschiedene Verfahren zur Aufheizung des Katalysators bekannt. Die DE 101 14 050 Al beschreibt zum Beispiel motorische Maßnahmen zum Aufheizen eines Katalysators, wobei die motorischen Maßnahmen aus einer Mehrfacheinspritzung und/oder einer Zündwinkelspätverstellung bestehen. Gerade in dieser Motorwarmlaufphase ist die Verbrennung aber sehr sensibel für die Partikelentstehung, sowohl im Hinblick auf die Partikelmasse, als auch auf die Partikelanzahl. Im speziellen vervielfacht sich die Partikelmasse und die Partikelanzahl bei dynamischen Vorgängen.The catalyst heating operation serves to bring the catalyst as quickly as possible to the light-off temperature (light-off temperature). Various methods for heating the catalyst are known. DE 101 14 050 A1 describes, for example, engine measures for heating a catalytic converter, wherein the engine measures consist of a multiple injection and / or an ignition retard adjustment. Especially in this engine warm-up phase, the combustion is very sensitive to the formation of particles, both in terms of particle mass, as well as the number of particles. In particular, the particle mass and the number of particles multiply during dynamic processes.
Es ist bekannt, durch Vorverstellen des Zündzeitpunktes die Brennraumtemperatur zu erhöhen, um Ablagerungen im Brennraum zu vermeiden oder zumindest zu reduzieren.It is known to increase the combustion chamber temperature by advancing the ignition timing in order to avoid or at least reduce deposits in the combustion chamber.
So beschreibt die WO 2006/105562 Al ein Verfahren zum Betreiben einer fremdgezündeten Brennkraftmaschine mit zumindest einer Zündeinrichtung, wobei zumindest in einem Betriebsbereich ein Russabbrand durch Erhöhen des thermischen Energieeintrages durchgeführt wird, wobei der Zündzeitpunkt der Zündeinrichtung unmittelbar nach dem Anlassen nach früh verstellt wird. Diese Maßnahme erfolgt völlig unabhängig vom Katalysatoraufheizbetrieb und unabhängig davon, ob ein dynamischer oder stationärer Betrieb vorliegt und zielt nur darauf ab, die Ablagerungen innerhalb des Brennraumes, insbesondere an den Brennraumwänden und der Zündeinrichtung, zu beseitigen. Aufgabe der Erfindung ist es, die Partikelanzahl und/oder Partikelmasse in den Emissionen eines fremdgezündeten Fahrzeuges während der Warmlaufphase deutlich zu verringern. - 2 -For example, WO 2006/105562 A1 describes a method for operating a spark-ignited internal combustion engine having at least one ignition device, wherein at least in one operating range a Rußabbrand is performed by increasing the thermal energy input, wherein the ignition timing of the ignition device is adjusted immediately after the start of early. This measure is completely independent of Katalysatoraufheizbetrieb and regardless of whether a dynamic or stationary operation is present and aims only to eliminate the deposits within the combustion chamber, in particular on the combustion chamber walls and the ignition device. The object of the invention is to significantly reduce the number of particles and / or particulate mass in the emissions of a spark-ignition vehicle during the warm-up phase. - 2 -
Erfindungsgemäß wird dies dadurch erreicht, dass die Vorverstellung des Zündzeitpunktes während zumindest eines Katalysatorheizbetriebes durchgeführt wird. Die Vorverstellung der Zündung kann auch mehrmals im Katalysatorbetrieb erfolgen.According to the invention this is achieved in that the advance of the ignition is carried out during at least one Katalysatorheizbetriebes. The advance of the ignition can also be done several times in the catalytic converter operation.
Besonders vorteilhaft ist es, wenn die Vorverstellung des Zündzeitpunktes unmittelbar vor zumindest einem dynamischen Betrieb der Brennkraftmaschine durchgeführt wird.It when the advance of the ignition is performed immediately before at least one dynamic operation of the internal combustion engine is particularly advantageous.
Dabei wird über eine Steuereinheit ständig oder in definierten Zeitintervallen geprüft, ob ein Katalysatorheizbetrieb vorliegt. Wenn festgestellt wird, dass die Brennkraftmaschine in einem Katalysatorheizbetrieb betrieben wird, wird in einem weiteren Verfahrensschritt geprüft, ob ein dynamischer Betrieb unmittelbar bevorsteht. Die beiden Prüfungsschritte können auch zeitlich vertauscht oder gleichzeitig erfolgen. Der unmittelbar bevorstehende dynamische Betriebsfall kann beispielsweise auf Grund einer einen dynamischen Betrieb auslösenden Handlung des Fahrers, wie z.B. Kupplungsbetätigung, Gangbetätigung oder Gaspedalbetätigung, oder durch vorrauschauende, auf einem Fahrleitsystem oder Navigationssystem basierende Fahrtroutenerkennung festgestellt werden.In this case, it is checked via a control unit constantly or at defined time intervals, if a catalyst heating operation is present. If it is determined that the internal combustion engine is operated in a catalytic converter heating operation, it is checked in a further method step whether dynamic operation is imminent. The two test steps can also be temporally swapped or simultaneous. The imminent dynamic operation case may be due, for example, to a driver's action triggering dynamic operation, such as a vehicle driver. Clutch actuation, gear operation or accelerator pedal operation, or be established by anticipatory, based on a driving guidance system or navigation system route recognition.
Durch die Vorverstellung der Zündung kommt es zu einem Ansteigen der Brennraumtemperatur. Es konnte festgestellt werden, dass durch das Ansteigen der Brennraumtemperatur durch Vorverstellen der Zündung der Zündeinrichtung die Partikelanzahl und die Partikelmasse in den Emissionen wesentlich reduziert werden kann. Diese Reduktion der Partikelemissionen ist darauf zurück zu führen, dass die höhere Brennraumtemperatur die Gemischbildung begünstigt, wodurch es zu einer deutlichen Reduzierung der Partikelmasse und der Partikelanzahl kommt. Des weiteren werden dynamische Vorgänge in der Motorwarmlaufphase vermindert, welche ebenfalls einen Einfluss auf die Partikelentstehung ausüben.The pre-adjustment of the ignition leads to an increase in the combustion chamber temperature. It has been found that by increasing the combustion chamber temperature by advancing the ignition of the ignition device, the number of particles and the particle mass in the emissions can be substantially reduced. This reduction in particulate emissions is attributable to the fact that the higher combustion chamber temperature promotes mixture formation, which results in a significant reduction in particle mass and particle number. Furthermore, dynamic processes are reduced in the engine warm-up phase, which also exert an influence on the particle formation.
Die Erfindung wird im folgenden an Hand der Fig. näher erläutert.The invention will be explained in more detail below with reference to FIG.
Es zeigen Fig. 1 das erfindungsgemäße Verfahren in einem schematischen Ablauf und Fig. 2 einen Vergleich der Partikelemissionen mit und ohne dem erfindungsgemäßen Verfahren.1 shows the method according to the invention in a schematic sequence and FIG. 2 shows a comparison of the particle emissions with and without the method according to the invention.
Die Fig. 1 zeigt das erfindungsgemäße Verfahren in einem Flussdiagramm. Nach einem Motorkaltstart 10 wird im Schritt 20 geprüft, ob ein Katalysatorheizbetrieb vorliegt, bzw. ob die Katalysatortemperatur unterhalb der Anspringtemperatur liegt. Wenn dies der Fall ist, wird in einem weiteren Prüfungsschritt 30 untersucht, ob ein dynamischer Betriebsfall unmittelbar bevorsteht. Für den Fall, dass kein Katalysatorheizbetrieb vorliegt bzw. dass die Anspringtemperatur des Katalysators erreicht wurde, kann das Verfahren beendet (Schritt 50) und erst beim - 3 - • · · ·· ·· · · ·· • · · ·· ·· · · · ··· • * · · ··· ·· ···· · • · · · · · ··· nächsten Motorstart erneut gestartet werden. Alternativ dazu kann die Abfrage 20 auch in einer durch die punktierte Linie angedeuteten Schleife kontinuierlich oder in definierten Zeitabständen fortgesetzt werden.FIG. 1 shows the method according to the invention in a flow chart. After a cold engine start 10, it is checked in step 20 whether there is a catalyst heating operation or whether the catalyst temperature is below the light-off temperature. If this is the case, a further test step 30 investigates whether a dynamic operating case is imminent. In the event that there is no catalyst heating operation or that the light-off temperature of the catalyst has been reached, the process can be terminated (step 50) and only when - 3 - • - ····················· ································································································································································ Alternatively, the query 20 can be continued continuously or at defined time intervals in a loop indicated by the dotted line.
Wenn erkannt wird, dass ein solcher dynamischer Betriebsfall unmittelbar bevorsteht, wird in Schritt 40 die Zündung für die Zündeinrichtungen der einzelnen Zylinder mindestens um 5°, vorzugsweise um mindestens 10° (bezogen auf den Katalysatorheizbetrieb) vorgestellt, und zwar solange, bis entweder der dynamische Betrieb beendet ist oder bis die Anspringtemperatur des Katalysators erreicht ist. Wenn mehrere dynamische Betriebe im Katalysatorheizbetrieb erkannt werden, kann die Zündung mehrmals über einen Zeitintervall Richtung früh verstellt werden.If it is detected that such a dynamic operation case is imminent, in step 40 the ignition for the individual cylinder igniters is presented at least 5 °, preferably at least 10 ° (based on the catalyst heating operation), until either the dynamic one Operation is completed or until the light-off temperature of the catalyst is reached. If multiple dynamic operations are detected in the catalyst heating mode, the ignition can be advanced several times over a time interval direction early.
In Fig. 2 sind im mittleren und unteren Bereich die aktuelle Partikelmasse PM, die aktuelle Partikelanzahl PN, die kumulative Partikelmasse PMC und die kumulative Partikelanzahl PNC für einen dynamischen Betriebsbereich innerhalb eines NEDC-Fahrzyklus (New European Driving Cycle) über der Zeit t aufgetragen. Weiters sind im oberen Abschnitt des Diagramms die Geschwindigkeit v des Fahrzeugs sowie der Zündzeitpunkt ti über der Zeit t aufgetragen. Die Kurven 1 bezeichnen dabei jeweils den Fall ohne Anwendung des erfindungsgemäßen Verfahrens und die Kurven 2 mit dem erfindungsgemäßen Verfahren.In FIG. 2, in the middle and lower regions, the actual particle mass PM, the actual particle number PN, the cumulative particle mass PMC and the cumulative particle number PNC are plotted over a time t for a dynamic operating range within a New European Driving Cycle (NEDC). Furthermore, in the upper section of the diagram, the speed v of the vehicle and the ignition timing ti are plotted over the time t. The curves 1 in each case denote the case without application of the method according to the invention and the curves 2 with the method according to the invention.
Deutlich ist zu entnehmen, dass sowohl die aktuellen, als auch die kumulativen Werte für die Partikelmasse PM, PMC und für die Anzahl der Partikel PN, PNC bei Anwendung des erfindungsgemäßen Verfahrens (Kurven 2) deutlich besser sind als die Werte welche sich ohne Anwendung des erfindungsgemäßen Verfahrens (Kurven 1) ergeben. Durch Vorverstellen der Zündung der Zündeinrichtung kann somit sowohl die Partikelanzahl PM, als auch die Partikelmasse PN in den Emissionen wesentlich reduziert werden. Diese Reduktion der Partikelemissionen ist darauf zurück zu führen, dass die höhere Brennraumtemperatur zu Folge der Vorverstellung des Zündzeitpunktes die Gemischbildung begünstigt, wodurch es zu einer deutlichen Reduzierung der Partikelmasse und der Partikelanzahl kommt. Des weiteren werden dynamische Vorgänge in der Motorwarmlaufphase vermindert, welche ebenfalls einen Einfluss auf die Partikelentstehung ausüben.It can be clearly seen that both the current and the cumulative values for the particle mass PM, PMC and for the number of particles PN, PNC when using the method according to the invention (curves 2) are significantly better than the values which are obtained without using the inventive method (curves 1). By Vorverstellen the ignition of the ignition device thus both the particle number PM, and the particle mass PN can be significantly reduced in the emissions. This reduction of particulate emissions is due to the fact that the higher combustion chamber temperature favors the mixture formation as a result of the advance of the ignition timing, resulting in a significant reduction of the particle mass and the number of particles. Furthermore, dynamic processes are reduced in the engine warm-up phase, which also exert an influence on the particle formation.
