Abstract

A controller (17) inputs values of combustion chamber temperatures (18, 20) and engine power (16) during running. The controller governs actuators (23, 23a) changing compressor (13) air throughput, to control this temperature (20). Control accords with a characteristic curve (22) optimized in terms of NOx emission and loading. Preferred features: The actuator controls a bypass (14) throttle (15) in the compressor line. It controls the exhaust turbo (12) bypass (14a) throttle (15a). Engine power is sensed from the generator (2). A thermocouple (20) in the cylinder head measures its temperature. The characteristic curve (22) is optimized with respect to NOx emission, in addition to the limits of misfire and pinking.

Description

Die Erfindung betrifft einen Diesel-Gasmotor, insbesondere Zündstrahl- Gasmotor, dessen mit einer Einspritzeinrichtung versehene Zylinder einlaß­ seitig an eine Verteilerleitung angeschlossen sind, die mit Verbrennungsluft oder einem Luft-Gasgemisch beaufschlagbar ist, wobei die Verbrennungsluft mittels eines durch eine Abgasturbine antreibbaren Verdichters verdichtbar ist.The invention relates to a diesel gas engine, in particular an ignition jet engine. Gas engine with an injector cylinder inlet are connected to a distribution line with combustion air or an air-gas mixture can be acted upon, the combustion air compressible by means of a compressor that can be driven by an exhaust gas turbine is.

Für die NOX-Emissionen sind Grenzwerte vorgegeben. Um diese einhalten zu können, ist bisher bei der Verbrennung von Gas eine Abgasnachbehandlung erforderlich.Limit values are specified for NO x emissions. In order to be able to comply with this, exhaust gas aftertreatment has so far been required when burning gas.

Die Aufgabe der vorliegenden Erfindung ist es, einen Motor eingangs erwähnter Art mit einfachen und kostengünstigen Mitteln so auszubilden, daß strenge NOX-Emissionsgrenzwerte bei der Verbrennung von Gas ohne Abgasnachbehandlung eingehalten werden können.The object of the present invention is to design an engine of the type mentioned at the outset using simple and inexpensive means in such a way that strict NO x emission limit values can be maintained during the combustion of gas without exhaust gas aftertreatment.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine bei der Verbrennung von Gas aktivierbare Regeleinrichtung vorgesehen ist, die einen mit der Brennraumtemperatur und der Motorleistung beaufschlagbaren Regler aufweist, der die Brennraumtemperatur mit einem gemäß einer zumindest bezüglich des NOX-Ausstoßes optimierten Kennlinie lastabhängig veränderbaren Sollwert vergleicht und in Abhängigkeit von der festgestellten Regelabweichung wenigstens ein den Luftdurchsatz durch den Verdichter beeinflussendes Stellglied befehligt.According to the invention, this object is achieved in that a control device which can be activated in the combustion of gas is provided and has a controller which can be acted upon with the combustion chamber temperature and the engine power and which controls the combustion chamber temperature with a setpoint value which can be changed as a function of the load in accordance with a characteristic curve which is optimized at least with respect to the NO x emissions compares and commands at least one actuator influencing the air flow through the compressor as a function of the determined control deviation.

Diese Maßnahmen stellen sicher, daß ein sehr mageres Luftverhältnis innerhalb einer sehr schmalen Bandbreite eingehalten werden kann, was eine Voraussetzung für die exakte Einhaltung strenger NOX- Emissionsgrenzwerte ist. Bei Motoren mit Vorkammer-Brennverfahren lassen sich hierdurch besonders gute Ergebnisse erreichen. Da die Brennraumtemperatur bei jeder Laststufe mit der NOX-Emission direkt korreliert und Änderungen des Gemischverhältnisses sehr schnell folgt, ist sichergestellt, daß die erfindungsgemäße Regeleinrichtung ohne nennenswerte Totzeiten sehr schnell anspricht. Dieser Vorteil wird dadurch unterstützt, daß die erfindungsgemäße Regeleinrichtung in die Verbrennungsluftzufuhr eingreift, wobei in vorteilhafter Weise die Gefahr von Regelkreisschwingungen gering ist. Da die gemäß der Erfindung vorgesehene Regelung der Brennraumtemperatur am Entstehungsort der Schadstoffe ansetzt, werden in vorteilhafter Weise äußere Störgrößen, wie schwankende Gasqualität, Änderungen von Ansauglufttemperatur und - druck etc. automatisch mit ausgeglichen.These measures ensure that a very lean air-fuel ratio can be maintained within a very narrow bandwidth, which is a prerequisite for precise adherence to strict NO X - emission limits. This enables particularly good results to be achieved for engines with prechamber combustion processes. Since the combustion chamber temperature correlates directly with the NO x emission at each load level and changes in the mixture ratio follow very quickly, it is ensured that the control device according to the invention responds very quickly without any significant dead times. This advantage is supported by the fact that the control device according to the invention intervenes in the combustion air supply, the risk of control circuit vibrations being advantageously low. Since the regulation of the combustion chamber temperature, which is provided according to the invention, starts at the point of origin of the pollutants, external disturbances, such as fluctuating gas quality, changes in intake air temperature and pressure, etc., are automatically compensated for in an advantageous manner.

Die EP 4 65 944 B1 beschreibt einen Otto-Gasmotor mit einer Regelein­ richtung, welche die Brennraumtemperatur und Motorleistung erfaßt und aus der Regelabweichung gegenüber einem gespeicherten Sollwert ein Stell­ signal zum Verstellen einer in der Gaszuleitung angeordneten Drosselklappe bildet. Luftseitig erfolgt hier keine Einwirkung, was hinsichtlich der erzielbaren Genauigkeit innerhalb kurzer Ansprechzeiten un­ günstig sein kann.EP 4 65 944 B1 describes an Otto gas engine with a control unit direction, which detects the combustion chamber temperature and engine power and off the control deviation compared to a stored setpoint signal for adjusting one arranged in the gas supply line Throttle valve forms. There is no influence on the air side, what regarding the achievable accuracy within short response times can be cheap.

Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der überge­ ordneten Maßnahmen sind in den Unteransprüchen angegeben.Advantageous refinements and expedient training of the supervised ordered measures are specified in the subclaims.

Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. Diese enthält eine schematische Darstellung eines Diesel-Gasmotors mit erfindungsgemäßer Regeleinrichtung. An embodiment of the invention is described below with reference to FIG Drawing explained in more detail. This contains a schematic representation of a diesel gas engine with a control device according to the invention.  

Der in der Zeichnung schematisch angedeutete Diesel-Gasmotor 1 dient zum Antrieb eines Generators 2. Der Aufbau und die Wirkungsweise von Anordnungen dieser Art sind an sich bekannt und bedürfen daher im vor­ liegenden Zusammenhang keiner näheren Erläuterung mehr.The diesel gas engine 1 indicated schematically in the drawing serves to drive a generator 2 . The structure and mode of operation of arrangements of this type are known per se and therefore do not require any further explanation in the present context.

Die Zylinder des Diesel-Gasmotors 1 sind mit einer Einspritzeinrichtung 3 zum Einspritzen von Diesel-Kraftstoff versehen und besitzen durch Ventile 4 steuerbare Ein- und Auslaßstutzen 5, 6. Die Einlaßstutzen 5 sind an eine mit Verbrennungsluft und Gas beaufschlagbare Verteilerleitung 7, die Aus­ laßstutzen 6 an eine Abgassammelleitung 8 angeschlossen. Die Zufuhr von Verbrennungsluft ist durch den Pfeil 9, die Zufuhr von Gas durch den Pfeil 10 angedeutet. Mit Hilfe der Einspritzeinrichtung 3 wird bei Gasbetrieb ein Zündstrahl in eine Vorkammer eingespritzt, was eine NOX-arme Gesamt­ verbrennung begünstigt.The cylinders of the diesel gas engine 1 are provided with an injection device 3 for injecting diesel fuel and have inlet and outlet ports 5 , 6 which can be controlled by valves 4 . The inlet nozzle 5 are connected to a combustible air and gas distribution line 7 , the outlet nozzle 6 connected to an exhaust manifold 8 . The supply of combustion air is indicated by the arrow 9 , the supply of gas by the arrow 10 . With the help of the injection device 3 , an ignition jet is injected into a prechamber during gas operation, which favors a low-NO x overall combustion.

Dem Diesel-Gasmotor 1 ist ein Abgas-Turbolader 11 zugeordnet, dessen Turbine 12 durch das die Abgassammelleitung 8 verlassende Abgas ange­ trieben wird, und dessen Verdichter 13 die der Verteilerleitung 7 zugeführte Verbrennungsluft verdichtet. Dem Verdichter 13 ist eine Kurzschlußleitung 14 zugeordnet, die den Ausgang des Verdichters mit seinem Eingang verbindet. In der Kurzschlußleitung 14 ist eine Drosseleinrichtung z. B. in Form einer Drosselklappe 15 angeordnet. Durch Betätigung der Drosselklappe 15 kann trotz großer Trägheit des Abgasturboladers 11 das der Verteilerleitung 7 zugeführte Luftvolumen schnell verändert werden.The diesel gas engine 1 is assigned an exhaust gas turbocharger 11 , the turbine 12 is driven by the exhaust gas leaving the exhaust manifold 8 , and the compressor 13 compresses the combustion air supplied to the distributor line 7 . A short-circuit line 14 is assigned to the compressor 13 and connects the output of the compressor to its input. In the short-circuit line 14 , a throttle device z. B. arranged in the form of a throttle valve 15 . By actuating the throttle valve 15 , the air volume supplied to the distributor line 7 can be changed quickly despite the high inertia of the exhaust gas turbocharger 11 .

Der Turbine 12 ist ebenfalls eine Kurzschlußleitung 14a zugeordnet, die den Eingang der Turbine 12 mit ihrem Ausgang verbindet. In der Kurzschlußleitung 14a ist eine Drosseleinrichtung in Form einer Drosselklappe 15a vorgesehen. Durch Betätigen der Drosselklappe 15a kann die der Turbine 12 zugeführte Antriebsenergie verändert werden, wodurch indirekt der Luftdurchsatz durch den Verdichter 13 und damit ebenfalls das der Verteilerleitung 7 zugeführte Luftvolumen verändert werden können, wobei zwar eine gewisse Trägheit zu berücksichtigen ist, aber ein vergleichsweise guter Wirkungsgrad gewährleistet wird. The turbine 12 is also associated with a short-circuit line 14 a, which connects the input of the turbine 12 to its output. A throttle device in the form of a throttle valve 15 a is provided in the short-circuit line 14 a. By actuating the throttle valve 15 a, the drive energy supplied to the turbine 12 can be changed, as a result of which the air throughput through the compressor 13 and thus also the air volume supplied to the distributor line 7 can be changed, although a certain inertia must be taken into account, but a comparatively good one Efficiency is guaranteed.

Bei dem der Verteilerleitung 7 zugeführten Gas kann es sich um Naturalgas, beispielsweise um in einer benachbarten Kläranlage anfallendes Klärgas, handeln das mit Hilfe der erfindungsgemäßen Anordnung zur Stromerzeugung Verwendung finden kann.The gas supplied to the distribution line 7 can be natural gas, for example sewage gas produced in an adjacent sewage treatment plant, which can be used to generate electricity with the aid of the arrangement according to the invention.

Das Verbrennungsluftverhältnis, das heißt das Verhältnis von Verbrennungsluft zu Gas, wird so geregelt, daß die NOX-Emission möglichst klein ist. Hierzu ist ein Regelkreis 16 vorgesehen, dessen Regler 17 mit dem Ist-Wert der zeitlich gemittelten Brennraumtemperatur (T) und dem Ist-Wert der Motorleistung (P) beaufschlagt wird, wie durch die Signal­ leitungen 18, 19 angedeutet ist. Die Brennraumtemperatur wird mittels eines Thermoelements 20 im Zylinderkopf von einem, einigen oder allen Zylindern des Diesel-Gasmotors 1 erfaßt. Zur Erfassung der Motorleistung wird die Leistung des Generators 2 elektrisch abgegriffen.The combustion air ratio, that is, the ratio of combustion air to gas, is regulated so that the NO x emission is as small as possible. For this purpose, a control circuit 16 is provided, the controller 17 is acted upon by the actual value of the time-averaged combustion chamber temperature (T) and the actual value of the engine power (P), as indicated by the signal lines 18 , 19 . The combustion chamber temperature is detected by means of a thermocouple 20 in the cylinder head of one, some or all of the cylinders of the diesel gas engine 1 . To detect the engine power, the power of the generator 2 is tapped electrically.

Dem Regler 17 ist ein Sollwertgeber 21 zugeordnet. Dieser kann in der Praxis in den Regler 17 integriert sein. Der Sollwertgeber 21 enthält im Versuch optimierte, lastabhängige Werte für die Brennraumtemperatur (T), wie durch die Kennlinie 22 angedeutet ist, durch welche die optimale Brenn­ raumtemperatur (T) über der Motorleistung (P) dargestellt wird. Die im Versuch durchgeführte Optimierung erfolgt zweckmäßiger bezüglich des NOX-Ausstoßes und der Aussetzer- und Klopfgrenze. Der Regler 17 vergleicht den zur jeweiligen Last gehörenden, aus der Kennlinie 22 entnommenen Sollwert der Brennraumtemperatur (T) mit der gemessenen Brennraumtemperatur und bildet im Falle von Abweichungen ein Stellsignal, durch das ein der Drosselklappe 15 in der Kurzschlußleitung 14 zugeordnetes Stellglied 22 und/oder der Drosselklappe 15a in der Kurzschlußleitung 14a zugeordnetes Stellglied 22a befehligt werden, wie durch die Signalleitungen 24, 24a angedeutet ist.A setpoint generator 21 is assigned to the controller 17 . In practice, this can be integrated in the controller 17 . In the experiment, the setpoint generator 21 contains optimized, load-dependent values for the combustion chamber temperature (T), as indicated by the characteristic curve 22 , by which the optimum combustion chamber temperature (T) is represented over the engine power (P). The optimization carried out in the experiment is more appropriate with regard to the NO x emission and the misfire and knock limit. The controller 17 compares the setpoint of the combustion chamber temperature (T) belonging to the respective load, taken from the characteristic curve 22 , with the measured combustion chamber temperature and, in the event of deviations, forms an actuating signal by means of which an actuator 22 and / or assigned to the throttle valve 15 in the short-circuit line 14 the throttle valve 15 a in the short-circuit line 14 a assigned actuator 22 a are commanded, as indicated by the signal lines 24 , 24 a.

Wenn der Ist-Wert der Brennraumtemperatur höher als der zugehörige, aus der Kennlinie 22 entnommene, zur tatsächlich vorhandenen Motorleistung gehörende Sollwert ist, wird z. B. die Drosselklappe 15 in Schließrichtung betätigt, wodurch der Durchsatz durch die Kurzschlußleitung 14 mehr gedrosselt wird. Dementsprechend wird der Verteilerleitung 7 mehr Luft zu­ geführt, was zu einer Absenkung der Brennraumtemperatur führt. Da diese mit der NOX-Emission direkt korreliert, ergibt sich hierdurch eine exakte Regelung der NOX-Emission. Sofern die gemessene Brennraumtemperatur zu niedrig sein sollte, wird die Drosselklappe 15 in Öffnungsrichtung beaufschlagt, wodurch die Luftzufuhr zur Verteilerleitung 7 gedrosselt wird. Alternativ oder parallel kann turbinenseitig eingegriffen werden, wobei durch Öffnen der Drosselklappe 15a die Turbinenleistung und damit die Luftförderung abgesenkt werden können und umgekehrt. Die Beeinflussung der verdichterseitigen Drosseleinrichtung ergibt eine gute Dynamik. Die Beeinflussung der turbinenseitigen Drosseleinrichtung ergibt einen guten Wirkungsgrad.If the actual value of the combustion chamber temperature is higher than the associated setpoint value taken from the characteristic curve 22 and belonging to the actually existing engine power, z. B. actuated the throttle valve 15 in the closing direction, whereby the throughput through the short-circuit line 14 is throttled more. Accordingly, more air is supplied to the distributor line 7 , which leads to a lowering of the combustion chamber temperature. Since this correlates directly with the NO X emission, this results in an exact regulation of the NO X emission. If the measured combustion chamber temperature is too low, the throttle valve 15 is acted upon in the opening direction, as a result of which the air supply to the distributor line 7 is throttled. Alternatively or in parallel, intervention can take place on the turbine side, it being possible to lower the turbine power and thus the air delivery and vice versa by opening the throttle valve 15 a. Influencing the throttle device on the compressor side results in good dynamics. Influencing the throttle device on the turbine side gives good efficiency.
