Description
Die Erfindung bezieht sich auf ein Verfahren zur thermischen Regeneration eines Partikelfilters für das Abgas eines einen Generator antreibenden Dieselmotors nach dem Oberbegriff des Patentanspruchs. Ohne Regeneration verstopfen Partikelfilter nach kurzer Zeit, was dann aufgrund steigenden Abgasgegendruckes zu Betriebsstörungen des Dieselmotors führt.The invention relates to a method for thermal Regeneration of a particle filter for the exhaust gas of one Generator driving diesel engine according to the preamble of Claim. Particle filters clog without regeneration after a short time, which is due to increasing exhaust gas back pressure leads to malfunctions of the diesel engine.
Aus der DE 36 08 370 A1 ist ein gattungsgemäßes Verfahren bekannt, das bei einem Fahrzeug-Motor zur Anwendung kommt. Die Temperaturerhöhung der Abgase für die thermische Regeneration des Partikelfilters wird dabei mit elektrischer Energie aus der Lichtmaschine bewirkt. Dazu wird die Lichtmaschine während der Schubphase des Fahrzeugbetriebes, d. h. bei Leerlauf des Motors, zugeschaltet, um kinetische Energie des Fahrzeugs in elektrische Energie umzuwandeln. Der Aufwand an elektrischer Energie ist bei diesem Verfahren zwangsläufig hoch, weil die betriebsbedingt niedrige Abgastemperatur bei Leerlauf des Motors einen großen Temperaturhub durch die elektrischen Heizelemente erfordert. Leistungsstarke Heizelemente sind aber groß und teuer. Dieses bekannte Verfahren ist zudem bei stationär eingesetzten Dieselmotoren wegen des Fehlens umwandelbarer kinetischer Energie nicht anwendbar.DE 36 08 370 A1 describes a generic method known that is used in a vehicle engine. The Exhaust gas temperature increase for thermal regeneration of the particle filter is generated with electrical energy from the Alternator causes. The alternator is used during the Thrust phase of vehicle operation, d. H. when the engine is idling, switched on to convert the vehicle's kinetic energy into electrical Convert energy. The expenditure of electrical energy is at this procedure is inevitably high because of the operational reasons low exhaust gas temperature when the engine is idling a large one Temperature rise required by the electrical heating elements. Powerful heating elements are large and expensive. This known method is also used in stationary Diesel engines because of the lack of convertible kinetic Energy not applicable.
Es ist deshalb Aufgabe der Erfindung, ein Verfahren zur thermischen Regeneration eines Partikelfilters für das Abgas eines einen Generator antreibenden Dieselmotors zu schaffen, bei dem der Primärenergieaufwand für eine Temperaturerhöhung des Abgases zur Auslösung einer thermischen Partikelfilter-Regeneration bei Teillast minimiert ist.It is therefore an object of the invention to provide a method for thermal regeneration of a particle filter for the exhaust gas of a diesel engine driving a generator that of the primary energy expenditure for a temperature increase of Exhaust gas to trigger a thermal Particulate filter regeneration at partial load is minimized.
Diese Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des Patentanspruches gelöst.This object is achieved with the characteristic Features of the claim solved.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß nur eine kleine Baugröße von elektrischen Heizelementen erforderlich ist, weil aufgrund der aus der Leistungssteigerung des Dieselmotors erwachsenden Abgastemperaturerhöhung der noch erforderliche Temperaturhub bis zur Entzündungstemperatur der abgeschiedenen brennbaren Abgasbestandteile klein ist, und daß sich durch die Abgaswärmenutzung eine verbesserte Brennstoffausnutzung gegenüber dem Bezug der elektrischen Energie aus einem öffentlichen Netz ergibt.The advantages achieved with the invention are in particular in that only a small size of electrical Heating elements is required because of the out of Increased performance of the adult diesel engine Exhaust gas temperature increase the required temperature increase up to to the ignition temperature of the separated combustible Exhaust components is small, and that by the Exhaust gas heat utilization an improved fuel utilization compared to the purchase of electrical energy from one public network results.
Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird nachstehend näher beschrieben. Es zeigen:An embodiment of the invention is in the drawings shown and will be described in more detail below. Show it:

Ein mit einem Partikelfilter 12 zur Abgasreinigung ausgerüsteter Dieselmotor 11 ist als Antriebsmaschine eines Generators 13 zur Stromversorgung eines Verbrauchers 16 eingesetzt. Um die Funktionsfähigkeit des Partikelfilters 12 aufrecht zu erhalten, ist die Beseitigung der im Partikelfilter 12 abgeschiedenen Abgasbestandteile von Zeit zu Zeit erforderlich. Bekannt und bewährt ist hierfür die sogenannte thermische Regeneration, bei der die im Partikelfilter angelagerten, brennbaren Abgasbestandteile entzündet und verbrannt werden.A diesel engine 11 equipped with a particle filter 12 for exhaust gas purification is used as the drive machine of a generator 13 for supplying power to a consumer 16 . In order to maintain the functionality of the particle filter 12 , it is necessary from time to time to remove the exhaust gas components separated out in the particle filter 12 . The so-called thermal regeneration is known and proven for this, in which the combustible exhaust gas constituents accumulated in the particle filter are ignited and burned.
Der Verlauf der Abgastemperatur T in Abhängigkeit der Leistung P eines Dieselmotors 11 zeigt die Kurve in Fig. 2. Bei einer Motorteilleistung PG erreicht das Abgas eine Grenztemperatur TG, ab der eine Selbstentzündung der im Partikelfilter 12 angelagerten, brennbaren Abgasbestandteile stattfindet. Betriebszeiten mit Leistungen des Dieselmotors 11 oberhalb der Motorleistung PG bewirken aufgrund ausreichender Abgastemperaturen durch Selbstentzündung automatisch die thermische Regeneration des Partikelfilters 12.The curve of the exhaust gas temperature T as a function of the power P of a diesel engine 11 is shown in the curve in FIG. 2. At a partial engine power P G , the exhaust gas reaches a limit temperature T G , at which the combustible exhaust gas components accumulated in the particle filter 12 self-ignite. Operating times with powers of the diesel engine 11 above the engine power P G automatically cause the thermal regeneration of the particle filter 12 due to sufficient exhaust gas temperatures due to self-ignition.
Bei Betrieb des Dieselmotors 11 im Leistungsbereich unterhalb der Motorleistung PG muß die Abgastemperatur T für die Auslösung einer Regeneration des Partikelfilters 12 durch Energiezufuhr auf die Grenztemperatur TG angehoben werden. Hierzu werden elektrisch betriebene Heizelemente 14 verwendet, die in einem vom Abgas durchströmten Behälter, bzw. innerhalb des Partikelfilters 12 angeordnet, oder in die Filterelemente des Partikelfilters 12 integriert sein können.When the diesel engine 11 is operating in the power range below the engine power P G , the exhaust gas temperature T for triggering regeneration of the particle filter 12 must be raised to the limit temperature T G by supplying energy. For this purpose, electrically operated heating elements 14 are used, which are arranged in a container through which the exhaust gas flows, or within the particle filter 12 , or can be integrated into the filter elements of the particle filter 12 .
Wenn der Dieselmotor 11 mit einer Teilleistung P1 betrieben wird, ergibt sich eine Abgastemperatur T1. Um die Selbstentzündung der im Partikelfilter 12 angelagerten Abgasbestandteile auszulösen, ist die Anhebung der Abgastemperatur von T1 auf TG erforderlich. Wird die elektrische Energie EÖ für die Heizelemente 14 einem öffentlichen Stromnetz entnommen, ergibt sich das in Fig. 3 dargestellte Energieflußdiagramm. Wenn man den Energieverbrauch EN = EÖ für den Temperaturhub TG-T1 gleich 100% setzt, beträgt zurückgerechnet der Primärenergieaufwand EK im Kraftwerk 285%. Dabei sind etwa 170% Kraftwerksverluste EV und etwa 15% Übertragungsverluste EÜ berücksichtigt.If the diesel engine 11 is operated with a partial power P 1 , an exhaust gas temperature T 1 results. In order to trigger the self-ignition of the exhaust gas components accumulated in the particle filter 12 , the exhaust gas temperature must be raised from T 1 to T G. If the electrical energy E Ö for the heating elements 14 is taken from a public electricity network, the energy flow diagram shown in FIG. 3 results. If you set the energy consumption E N = E Ö for the temperature stroke T G -T 1 to 100%, the primary energy expenditure E K in the power plant is 285%. Approx. 170% power plant losses E V and approx. 15% transmission losses E Ü are taken into account.
Wird hingegen die elektrische Energie EH für die Heizelemente 14 direkt an den Generatorklemmen 15 entnommen, muß der Dieselmotor 11 zwangsläufig mit einer etwas erhöhten Leistung P2 betrieben werden, damit die vom Generator 13 an den Verbraucher 16 abgegebene elektrische Leistung gleich bleibt. Die Leistungssteigerung von P1 nach P2 des Dieselmotors 11 bewirkt aber eine Erhöhung der Abgastemperatur von T1 auf T2. Die jetzt noch von den Heizelementen 14 aufzubringende Heizleistung für die Temperaturerhöhung TG-T2 des Abgases um den Energiebetrag EA, der aus der im Betriebspunkt P2 gegenüber P1 erhöhten Abgastemperatur T2 resultiert, ist niedriger als die erforderliche elektrische Energie EÖ nach dem vorherigen Beispiel. Das Energieflußdiagramm nach Fig. 4 für dieses Verfahren zeigt, daß die für den gesamten Temperaturhub TG-T1 erforderliche Energie EN sich etwa zur Hälfte aus Abgasenergie EA aufgrund der erhöhten Abgastemperatur und zur anderen Hälfte aus der dem Generator entnommenen elektrischen Energie EH für die Heizelemente 14 zusammensetzt. Für EN = EA + EH = 100% ergibt sich zurückgerechnet ein Primärenergieaufwand ED am Dieselmotor von 130%, wobei Generatorverluste EG von etwa 3% und Kühlwasserverluste EW von etwa 27% berücksichtigt sind. Das vorgeschlagene Verfahren zeichnet sich demnach durch einen wesentlich geringeren Primärenergieaufwand aus, was eine verbesserte Brennstoffausnutzung bedeutet.If, on the other hand, the electrical energy E H for the heating elements 14 is taken directly from the generator terminals 15 , the diesel engine 11 must inevitably be operated with a somewhat increased power P 2 so that the electrical power delivered by the generator 13 to the consumer 16 remains the same. However, the increase in performance from P 1 to P 2 of the diesel engine 11 causes an increase in the exhaust gas temperature from T 1 to T 2 . The heating power still to be applied by the heating elements 14 for the temperature increase T G -T 2 of the exhaust gas by the energy amount E A , which results from the exhaust gas temperature T 2 increased at the operating point P 2 compared to P 1 , is lower than the required electrical energy E Ö following the previous example. The energy flow diagram according to FIG. 4 for this method shows that the energy E N required for the entire temperature stroke T G -T 1 is approximately half of the exhaust gas energy E A due to the increased exhaust gas temperature and half of the electrical energy E taken from the generator H composed for the heating elements 14 . For E N = E A + E H = 100%, the primary energy expenditure E D on the diesel engine is calculated back, taking into account generator losses E G of approximately 3% and cooling water losses E W of approximately 27%. The proposed method is therefore characterized by a significantly lower primary energy expenditure, which means improved fuel utilization.
