Abstract
Description
Die Erfindung betrifft ein Steuerungs- und Regelsystem für Schmierölparameter eines Abgasturboladers.The invention relates to a control system for lubricating oil parameters of an exhaust gas turbocharger.
Die Erfindung geht von Abgasturboladern aus wie sie üblicherweise in Verbrennungsmotoren, wie Großdieselmaschinen zum Einsatz kommen. Für die heutigen Anforderungen bezüglich der Verdichterdruckverhältnisse sind entsprechend hohe Drehzahlen der Turbolader erforderlich. Es ist allgemein bekannt die Ölversorgung der Rotorlager hinsichtlich des Zulaufdrucks und der Eintrittstemperatur für die Maximaldrehzahl auszulegen.The invention is based on exhaust gas turbochargers as is usually the case in Internal combustion engines, such as large diesel engines, are used. For the today's requirements regarding the compressor pressure ratios correspondingly high speeds of the turbochargers are required. It is general known the oil supply to the rotor bearings with regard to the inlet pressure and Design inlet temperature for the maximum speed.
Damit ist im unteren Drehzahlbereich des Turboladers, d. h. bei Teillast des Verbrennungsmotors der Öldurchsatz und die Viskosität zu hoch. Dies führt bei solchen Betriebsverhältnissen zu überproportional hohen Verlusten.This is in the lower speed range of the turbocharger, ie. H. at partial load of Internal combustion engine's oil throughput and viscosity too high. This leads to such operating conditions at disproportionately high losses.
Hiervon ausgehend ist es die Aufgabe der Erfindung ein einfaches Schmierungssystem zu schaffen durch das eine, verschiedenen Betriebspunkten angepaßte, Ölversorgung der Lager über den gesamten Drehzahlbereich eines Abgasturboladers gewährleistet wird.Proceeding from this, the object of the invention is a simple one Lubrication system to create through one, different operating points adapted, oil supply to the bearings over the entire speed range Exhaust gas turbocharger is guaranteed.
Diese Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with the characterizing features of Claim 1 solved.
Durch die erfindungsgemäße Regelung des Öldrucks und/oder der Öltemperatur im Zulauf eines Abgasturboladers wird die Ölversorgung der Lager dem tatsächlichen Bedarf entsprechend den jeweiligen Betriebsbedingungen angepaßt. Damit wird ein überflüssig hoher Öldurchsatz und die damit verbundenen mechanischen sowie thermischen Verluste vermieden, wodurch in vorteilhafterweise der Teillastwirkungsgrad des Aufladesystems erhöht wird. Dies führt besonders bei hochaufgeladenen Motoren zu verbessertem Hochlauf- und Lastzuschaltvermögen.By regulating the oil pressure and / or the oil temperature according to the invention in the inlet of an exhaust gas turbocharger, the oil supply to the bearings actual needs adjusted according to the respective operating conditions. This results in an unnecessarily high oil throughput and the associated mechanical and thermal losses avoided, which in the partial load efficiency of the charging system is advantageously increased. This leads to improved run-up and Load switching capacity.
Mit der erfindungsgemäßen Anordnung ist es möglich, die Zutauftemperatur und 1 oder den Zulaufdruck des Schmieröls bedarfsgerecht einzustellen, so daß bei geringsten mechanischen Verlusten ein sicherer Betrieb eines Abgasturboladers gewährleistet wird.With the arrangement according to the invention, it is possible to adjust the inlet temperature and 1 or adjust the inlet pressure of the lubricating oil as required, so that at lowest mechanical losses a safe operation of an exhaust gas turbocharger is guaranteed.
Anhand der beigefügten schematischen Zeichnung wird die Erfindung nachfolgend näher erläutert.The invention is described below with the aid of the attached schematic drawing explained in more detail.
Die Fig. 1 zeigt die prinzipielle Anordnung der Elemente des Steuerungs- und Regelsystems, vorzugsweise bestehend aus einer Druckregeleinheit (1), einer Temperaturregeleinheit (2) sowie Meßfühlern (3, 6, 7) in den Ölzu- bzw. ablaufleitungen der Rotorlager am Abgasturbolader (5) und einer Steuerungs und/oder Regelungseinheit (4). Fig. 1 shows the basic arrangement of the elements of the control system, preferably consisting of a pressure control unit ( 1 ), a temperature control unit ( 2 ) and sensors ( 3 , 6 , 7 ) in the oil supply and discharge lines of the rotor bearings on the exhaust gas turbocharger ( 5 ) and a control and / or regulating unit ( 4 ).
Unter der Druckregeleinheit (1) und der Temperaturregeleinheit (2) sind ansteuerbare Stelleinrichtungen zu verstehen mit welchen vorgegebene Werte für die jeweilige physikalische Größe einstellbar sind.The pressure control unit ( 1 ) and the temperature control unit ( 2 ) are to be understood as actuatable control devices with which predetermined values for the respective physical variable can be set.
Der Abgasturbolader (5) wird in üblicher Weise bei Verbrennungsmotoren, insbesondere Großdieselmaschinen, verwendet. Die Rotorwelle des Abgasturboladers mit Turbinenrad und Verdichterrad ist in allgemein üblicher Art gelagert.The exhaust gas turbocharger ( 5 ) is used in a conventional manner in internal combustion engines, in particular large diesel engines. The rotor shaft of the exhaust gas turbocharger with turbine wheel and compressor wheel is mounted in a generally customary manner.
Am Abgasturbolader wird über einen Drehzahlsensor (7) die Rotordrehzahl abgenommen und der Steuerungs und/oder Regelungseinheit (4) zugeführt. Anhand dieser für den jeweiligen Betriebspunkt spezifischen Führungsgröße werden mittels einer programmierbaren Steuerung, wie beispielsweise einer Speicherprogrammierbaren Steuerung (SPS) oder einem Integrierten Schaltkreis (IC), aus einer abgespeicherten Vergleichstabelle Einstellwerte für den Öldruck sowie die -temperatur ermittelt und an der Druckregeleinheit (1) bzw. Temperaturregeleinheit (2) eingestellt. The rotor speed on the exhaust gas turbocharger is measured by a speed sensor ( 7 ) and fed to the control and / or regulating unit ( 4 ). Using this reference variable specific to the respective operating point, setting values for the oil pressure and temperature are determined using a programmable controller, such as a programmable logic controller (PLC) or an integrated circuit (IC), and are determined on the pressure control unit ( 1 ). or temperature control unit ( 2 ) set.
Als Führungsgröße wird vorzugsweise die einfach meßbare Rotordrehzahl eingesetzt, es ist jedoch auch jede andere, für verschiedene Betriebspunkte, spezifische Größe dazu geeignet.The easily measurable rotor speed is preferably used as the reference variable used, but it is also any other, for different operating points, specific size suitable for this.
Die spezifischen Kenngrößen für optimalen Öldruck und -temperatur an verschiedenen Betriebspunkten werden vorzugsweise an Prüfständen für jeden Turboladertyp und jede Baugröße gesondert ermittelt und in datenverarbeitungsgerechter Weise gespeichert. Darüber hinaus sind selbstverständlich auch Berechnungsverfahren oder sonstige Methoden geeignet, um die jeweiligen Kenngrößen für die verschiedenen Betriebspunkte des Abgasturboladers (5), über seinen gesamten Drehzahlbereich zu ermitteln.The specific parameters for optimum oil pressure and temperature at various operating points are preferably determined separately on test benches for each turbocharger type and size and saved in a manner suitable for data processing. In addition, of course, calculation methods or other methods are also suitable for determining the respective parameters for the various operating points of the exhaust gas turbocharger ( 5 ) over its entire speed range.
Die Druckregeleinheit (1) ist z. B. als ansteuerbares Druckregelventil ausgeführt, jede andere ansteuerbare Druckregelvorrichtung ist jedoch auch einsetzbar.The pressure control unit ( 1 ) is e.g. B. designed as a controllable pressure control valve, but any other controllable pressure control device can also be used.
Die Temperaturregeleinheit (2) ist beispielsweise ein Wärmetauscher durch den das Öl entweder erwärmt oder auch gekühlt werden kann. Er ist vorzugsweise in der Ölzulaufleitung vor dem Abgasturbolader (5) angeordnet.The temperature control unit ( 2 ) is, for example, a heat exchanger through which the oil can either be heated or cooled. It is preferably arranged in the oil feed line upstream of the exhaust gas turbocharger ( 5 ).
Mit den von der Steuerungs und/oder Regelungseinheit (4) ermittelten Einstellwerten für Öldruck bzw. -temperatur können die Regeleinheiten (1, 2) sowohl miteinander kombiniert oder unabhängig voneinander angesteuert werden und die Parameter entsprechend eingestellt werden.With the setting values for oil pressure or temperature determined by the control and / or regulating unit ( 4 ), the regulating units ( 1 , 2 ) can be combined with one another or controlled independently of one another and the parameters can be set accordingly.
Durch den druckgesteuerten verminderten Öldurchsatz bei niedrigeren Rotordrehzahlen des Turboladers (5) werden die Planschverluste kleiner und durch ein Ansteigen der Lagertemperatur sinkt die Viskosität ab, wodurch sich die Reibungsverluste reduzieren.The pressure-controlled, reduced oil throughput at lower rotor speeds of the turbocharger ( 5 ) reduces the churning losses and, as the bearing temperature rises, the viscosity drops, which reduces the friction losses.
Durch die Ansteuerung der Temperaturregeleinheit (2) zur Erhöhung der Öltemperatur kann die Viskosität ebenfalls abgesenkt und damit die Reibungsverluste reduziert werden.By controlling the temperature control unit ( 2 ) to increase the oil temperature, the viscosity can also be reduced and thus the friction losses can be reduced.
Durch Optimierungsrechnungen bzw. Versuche am Prüfstand können für verschiedene Betriebspunkte ideale Kombinationen der Einstellwerte für die Druckregeleinheit (1) und die Temperaturregeleinheit (2) ermittelt werden. Neben der bisher beschriebenen Steuerungsfunktion können mit der Steuerungs und/oder Regelungseinheit (4) die ermittelten Einstellwerte für Öldruck und temperatur auch eingeregelt werden. Dazu werden die vom, vor dem Abgasturbolader (5) angeordneten, Meßfühler (3) aufgenommenen tatsächlichen Werte des Öldrucks und der -temperatur an die Steuerungs und/oder Regelungseinheit (4) weitergegeben, dort mit den entsprechenden Sollwerten verglichen und die einzelnen Regeleinheiten (1, 2) werden bis zum Erreichen des entsprechenden Sollwerts nachgeführt.Optimization calculations or tests on the test bench can be used to determine ideal combinations of the setting values for the pressure control unit ( 1 ) and the temperature control unit ( 2 ) for different operating points. In addition to the control function described so far, the control and / or regulating unit ( 4 ) can also be used to regulate the determined setting values for oil pressure and temperature. For this purpose, the actual oil pressure and temperature values recorded by the sensor ( 3 ) arranged in front of the exhaust gas turbocharger ( 5 ) are passed on to the control and / or regulating unit ( 4 ), compared there with the corresponding setpoints and the individual regulating units ( 1 , 2 ) are tracked until the corresponding setpoint is reached.
Weiterhin ist es mit der Steuerungs und/oder Regelungseinheit (4) möglich ein Sicherheitsprogramm zu aktivieren. Durch Überwachung der Ölablauftemperatur mittels eines Meßfühlers (6), der in der Ölablaufleitung angeordnet ist, werden bei Erkennung des Überschreitens einer abgespeicherten zulässigen Grenztemperatur alle einstellbaren Parameter, wie beispielsweise der Öldruck und die -temperatur, automatisch auf die Größen für maximale Drehzahl eingestellt. Dadurch werden die Beschädigungen oder die Zerstörung der Lager verhindert. It is also possible to activate a safety program with the control and / or regulating unit ( 4 ). By monitoring the oil drain temperature using a sensor ( 6 ), which is arranged in the oil drain line, all adjustable parameters, such as the oil pressure and temperature, are automatically set to the values for maximum speed when a stored permissible limit temperature is exceeded. This prevents damage or destruction of the bearings.
