Abstract
Description
Bei einem Common Rail-Dieselmotor (CR DI) sind trotz hohem Brenn stoff-Druck und feiner Brennstoff-Zerstäubung sowie einem nachgeschalteten Oxy dationskatalysator im Leerlauf und Teillastbetrieb des Motors die Abgastemperatu ren zu niedrig, um den Rußausstoß des Motors in akzeptablen Grenzen zu halten. Deshalb ist dem Oxydationskatalysator ein Rußfilter nachgeschaltet, der den größ ten Teil des entstehenden Rußes zurückhält. Wenn sich zu viel Ruß ansammelt, steigt der Durchflusswiderstand für die Abgase des Motors. Der angesammelte Ruß im Filter muss nunmehr abgebrannt werden. Hierzu existiert eine Vorrichtung zum Messen des Beladungszustands des Rußfilters und eine Motorsteuerung zur be darfsgerechten Verbrennung des Rußes. Die Motorsteuerung aktiviert im Bedarfs fall die Nacheinspritzung von Brennstoff in die Brennkammer und gleichzeitig die Beimengung eines Additivs zum Brennstoff.With a common rail diesel engine (CR DI), despite high combustion fabric pressure and fine fuel atomization as well as a downstream oxy dationskatalyst in idle and part-load operation of the engine, the exhaust gas temperature too low to keep the engine's soot emissions within acceptable limits. Therefore, a soot filter is connected downstream of the oxidation catalyst, which is the largest holds back part of the soot. If too much soot accumulates, the flow resistance for the exhaust gases of the engine increases. The accumulated soot the filter must now be burned down. For this purpose there is a device for Measuring the loading condition of the soot filter and an engine control for loading proper combustion of the soot. The engine control activates when required the post-injection of fuel into the combustion chamber and at the same time Addition of an additive to the fuel.
Die Nacheinspritzung von Brennstoff dient zur Anhebung der Abgastemperatur in der Brennkammer und zur Brennstoffanreicherung im Abgas, um zusätzliche Verbrennung im nachgeschalteten Oxydationskatalysator und die weitere Temperaturerhöhung der Abgase zu bewirken. Die Abgase beheizen den abgelagerten Ruß, und weil durch die vorangegangene Additivbeimengung zum Brennstoff die Zündtemperatur des Rußes gesunken ist, reagiert die überschüssige Luft im Abgas mit dem erhitzten Ruß, der Rußabbrand im beladenen Filter beginnt.The post-injection of fuel serves to raise the Exhaust gas temperature in the combustion chamber and for fuel enrichment in the exhaust gas, for additional combustion in the downstream oxidation catalytic converter and the cause a further increase in temperature of the exhaust gases. The exhaust gases heat the deposited soot, and because of the previous additive admixture to If the ignition temperature of the soot has dropped, the excess reacts Air in the exhaust gas with the heated soot, the soot burn-off in the loaded filter begins.
Wenn die Messvorrichtung den Leerzustand des Filters anzeigt, schaltet die Steuerung sofort auf normalen Motorbetrieb.When the measuring device shows the empty state of the filter, the Control immediately on normal engine operation.
Das Ergebnis ist die nahezu vollständige Verbrennung des Rußes im Filter. Menge und Größe der den Filter verlassenden Rußpartikel im Abgas sind nahe an der Nachweisgrenze.The result is the almost complete combustion of the soot in the filter. The amount and size of the soot particles leaving the filter in the exhaust gas are close to the detection limit.
Die Kosten und der Platzbedarf der Additivanlage samt Leitungsverlegung sind sehr hoch. Das zusätzliche Tanken von Additiv ist für den Fahrer unangenehm und erfordert eine aufwendige weitverzweigte Logistik. The costs and space requirements of the additive system including the laying of the cables are very high. Additive refueling is uncomfortable for the driver and requires complex, complex logistics.
Dieses Verfahren der Filterregenerierung ist technisch auf Dieselmotoren mit Common Rail-Einspritzverfahren begrenzt. Wegen seiner hohen Kosten ist der breitgefächerte Einsatz bei Fahrzeugen der mittleren und unteren Preisklassen ge fährdet.This method of filter regeneration is technical on diesel engines limited with common rail injection. Because of its high cost, the Wide range of uses for vehicles in the middle and lower price categories jeopardized.
Bei Motoren mit anderen Verfahren der Brennstoffeinspritzung sind keine kommerziell einsetzbaren Maßnahmen für eine vergleichbare hohe Reduzierung des Rußes bekannt.In engines with other methods of fuel injection there are none commercially usable measures for a comparable high reduction of Soot known.
Generell zeigen alle modernen Dieselmotoren sehr schlechte Leistung der Kabinenheizung.Generally, all modern diesel engines show very poor performance Cab heating.
Leicht regenerierbare Rußfilter sollen bei allen Fahrzeugen mit Dieselmoto ren kurzfristig und kostengünstig realisierbar werden, insbesondere bei bereits in Entwicklung und Serienfertigung befindlichen Motorbaureihen.Easily regenerable soot filters should be used in all vehicles with a diesel engine ren can be realized quickly and inexpensively, especially with already in Development and series production of existing engine series.
Bei Regenerierungsbedarf soll die Zündung der Rußverbrennung möglichst schnell erfolgen, und danach ist ein ausreichender Luftanteil in den dem Filter zu fließenden Abgasen zu sichern. Unkontrollierte Abbrände sind zu vermeiden.If regeneration is required, the soot combustion should be ignited as far as possible done quickly, and then there is a sufficient amount of air in the filter to secure flowing exhaust gases. Uncontrolled burns must be avoided.
Der niedrige Brennstoffverbrauch und das gute Fahrverhalten moderner Dieselmotoren sollen erhalten bzw. ausgebaut und die Kabinenheizung soll verbes sert werden.The low fuel consumption and the good driving behavior more modern Diesel engines should be maintained or expanded and the cabin heating should improve be tested.
Zur Einleitung des Rußabbrandes wird die Temperatur der in den Filter ein tretenden Motorabgase mindestens auf das Reaktionsniveau der additivfreien Ab gase mit dem abgelagerten Ruß angehoben, bis die Rußoberfläche genügend auf geheizt ist. Zur Zündung der Rußverbrennung wird die Abgastemperatur gegebe nenfalls zugunsten eines ausreichenden Sauerstoffanteils reduziert. Während des folgenden Rußabbrandes ist der Massenstrom des Sauerstoffs in den Abgasen des Motors unter Berücksichtigung der maximal zulässigen Brennrate begrenzbar.To initiate the soot burn-up, the temperature is entered into the filter occurring engine exhaust gases at least to the reaction level of the additive-free exhaust Gases with the deposited soot are raised until the soot surface is sufficiently open is heated. The exhaust gas temperature is given to ignite the soot combustion if necessary, reduced in favor of a sufficient proportion of oxygen. During the following soot burnup is the mass flow of oxygen in the exhaust gases of the Motor can be limited taking into account the maximum permissible burning rate.
Bei Motoren mit Nacheinspritzung oder Späteinspritzung von Brennstoff und zusätzlicher Verbrennung von überschüssigem Brennstoff in einem nachge schalteten Oxydationskatalysator wird die Abgastemperatur durch die Erhitzung der Brennluft des Motors vor Beginn der Kolbenverdichtung erhöht oder durch die Drosselung der Abgase.For engines with post-injection or late injection of fuel and additional combustion of excess fuel in one post switched oxidation catalyst, the exhaust gas temperature by heating the Combustion air of the engine increased before the start of piston compression or by the Throttling the exhaust gases.
Bei Motoren ohne Nacheinspritzung oder Späteinspritzung von Brennstoff wird die Brennluft des Motors vor Beginn der Kolbenverdichtung erhitzt und die Abgase werden gedrosselt.For engines without post-injection or late injection of fuel the combustion air of the engine is heated before the piston compression begins and the Exhaust gases are throttled.
Wahlweise werden die Abgastemperaturen durch Zylinderabschaltung, zylinderselektive Abgasrückführung und Luftmengenreduzierung erhöht.Optionally, the exhaust gas temperatures through cylinder deactivation, Cylinder-selective exhaust gas recirculation and air volume reduction increased.
Brennlufterhitzung durch sequentielle Lufteinbringung, z. B. durch Wärmeladung mit einem Lufttaktventil (LTV), hat den Vorteil, dass Abgastempe ratur und Luftdurchsatz schnell und unabhängig voneinander gesteuert werden kön nen.Combustion air heating by sequential air introduction, e.g. B. by Heat charging with an air cycle valve (LTV) has the advantage that exhaust temp temperature and air flow can be controlled quickly and independently of each other NEN.
Zur Erzielung maximaler Abgastemperaturen während der Aufheizphase des Luftfilters kann das Brennstoff/Luft-Verhältnis im Motor bis in den Rußbereich angehoben werden, wobei der Motor durch z. B. Wärmeladung und Abgasdrosse lung entsprechend belastet wird.To achieve maximum exhaust gas temperatures during the heating phase of the air filter can increase the fuel / air ratio in the engine to the soot area be raised, the engine by z. B. heat charge and exhaust pipe lung is charged accordingly.
Die Abgasdrosselung kann auch zur Verbesserung der Kabinenheizung angesteuert werden und Wärme im Abgas kann stromab vom Rußfilter durch Wär metausch mit dem Kühlmittel des Motors entzogen und der Kabinenheizung zuge führt werden.Exhaust throttling can also improve cabin heating can be controlled and heat in the exhaust gas can downstream from the soot filter by heat exchanged with the coolant of the engine and removed the cabin heating leads.
Die Zeichnung veranschaulicht in schematischer Weise die Steuerung des Rußabbrandes eines Rußfilters in einem Dieselmotor.The drawing schematically illustrates the control of the Soot burn-off in a soot filter in a diesel engine.
