Abstract
Description
Die Erfindung betrifft ein Gasdruck-Regelventil zur Regelung der einer Gas-Luft-betriebenen Brennkraftmaschine zuzuführenden Gasmenge, wobei das Regelventil ein Ventilgehäuse mit einem von einer Ventilstange betätigten mit einem Sitzring zusammenwirkenden Ventilstellglied aufweist und die Ventilstange mit einer Differenzdruck-Stelleinrichtung wirkverbunden ist sowie ein Verfahren zur Verstellung eines solchen Gasdruck-Regelventils.The The invention relates to a gas pressure control valve for controlling the one Gas-air-fueled internal combustion engine to be supplied amount of gas, the Control valve a valve body with a valve rod actuated by a seat ring cooperating Valve actuator and the valve rod operatively connected to a differential pressure actuator is and a method for adjusting such a gas pressure control valve.
Ein
derartiges Gasdruck-Regelventil ist aus der
Der Erfindung liegt die Aufgabe zugrunde, ein Gasdruck-Regelventil bzw. ein Verfahren zur Verstellung eines Gasdruck-Regelventils bereitzustellen bzw. anzugeben, mit dem ein größtmöglicher Spielraum bei der Regelung der der Brennkraftmaschine zuzuführenden Gasmenge besteht.Of the Invention is based on the object, a gas pressure control valve or to provide a method for adjusting a gas pressure control valve specify the largest possible Scope in the regulation of the internal combustion engine to be supplied Gas quantity exists.
Diese Aufgabe wird dadurch gelöst, dass eine beliebige Stellung zwischen zwei Endstellungen einstellender Steller vorhanden ist, der mit einer Betriebspunkt-Stelleinrichtung oder der Differenzdruck-Stelleinrichtung oder dem Sitzring verbunden ist bzw. diese Teile verstellt. Ist der Steller mit der Betriebspunkt-Stelleinrichtung verbunden, ist der Betriebspunkt individuell verstellbar und die Differenzdruck-Stelleinrichtung kann im Bereich des jeweiligen Betriebspunktes sehr genau die der Brennkraftmaschine zuzuführende Gasmenge einstellen. Vorteilhaft ist es auch, wenn der Steller direkt mit der Differenzdruck-Stelleinrichtung verbunden ist. In diesem Fall kann auf die Betriebspunkt-Stelleinrichtung verzichtet werden und der Steller steuert direkt die Differenzdruck-Stelleinrichtung an. Grundsätzlich könnte bei dieser Ausführung auf die eigentlichen Bauteile (beispielsweise Membran und Membranteller) der Differenzdruck-Stelleinrichtung verzichtet werden. Es ist aber vorteilhaft, diese Bauteile beizubehalten, um beispielsweise bei Ausfall des Stellers noch eine eingeschränkte Regelung des der Brennkraftmaschine zuzuführenden Gases vornehmen zu können. Dabei ist es bei einem Ausfall des Stellers so, dass die Differenzdruck-Stelleinrichtung in geeigneter Weise von dem Steller entkoppelt wird und somit ungehindert arbeiten kann. Im Übrigen ist auch bei Ausfall des mit der Betriebspunkt-Stelleinrichtung verbundenen Stellers ein eingeschränkter Betrieb der Brennkraftmaschine möglich, wenn sichergestellt ist, dass für einen solchen Fall die Betriebspunkt-Stelleinrichtung in eine definierte Stellung verfährt und die Differenzdruck-Stelleinrichtung den gesamten Betriebsbereich abdeckt. Insbesondere alternativ zu der Einwirkung des Stellers auf die Differenzdruck-Stelleinrichtung kann der Steller mit dem Sitzring zusammenwirken und diesen in Bezug zu dem Ventilstellglied verstellen.These Task is solved by that adjusting any position between two end positions Steller is present, with an operating point-adjusting device or the differential pressure actuator or the seat ring is connected or adjusted these parts. Is the actuator with the operating point adjusting device connected, the operating point is individually adjustable and the Differential pressure actuator can in the range of the respective operating point very accurately adjust the gas to be supplied to the engine. It is also advantageous if the actuator directly with the differential pressure actuator connected is. In this case, can waive the operating point-adjusting device and the controller directly controls the differential pressure actuator at. Basically, at this version on the actual components (eg diaphragm and diaphragm plate) the differential pressure actuator can be omitted. But it is advantageous to maintain these components, for example, at Failure of the actuator still a limited control of the internal combustion engine supplied Gas to make. It is in case of failure of the actuator so that the differential pressure actuator is decoupled in a suitable manner from the actuator and thus unhindered can work. Furthermore is also connected in case of failure of the operating point adjusting device Steller's a limited Operation of the internal combustion engine possible, if it is certain that for In such a case, the operating point adjusting device in a defined Position moves and the differential pressure actuator the entire operating range covers. In particular, as an alternative to the action of the actuator on the differential pressure actuator, the actuator with the Seat ring interact and this with respect to the valve actuator adjust.
In Weiterbildung der Erfindung ist der Steller bevorzugt ein Elektrosteller, beispielsweise ein Drosselklappensteller. Solche Steller stehen zur Verfügung und zeichnen sich durch hohe Verstellgeschwindigkeiten aus. Es ist somit möglich, sehr schnell, beispielsweise auf Laständerung beispielsweise an einem von der Brennkraftmaschine angetriebenen Generator, zu reagieren und die dem Lastpunkt entsprechende Einstellung der Brennkraftmaschine vorzunehmen.In Further development of the invention, the actuator is preferably an electric actuator, for example, a throttle valve actuator. Such stops are available to disposal and are characterized by high adjustment speeds. It is thus possible very fast, for example on load change, for example on a driven by the internal combustion engine generator to respond and the load point corresponding setting of the internal combustion engine make.
In weiterer Ausgestaltung der Erfindung ist der Elektrosteller mit einer Einrichtung ausgestattet, die ein Rückführsignal abgibt. Dieses Rückführsignal gibt die augenblickliche Position des Elektrostellers wieder und es kann somit ein noch schnelleres Anfahren einer bestimmten Position, die beispielsweise einem Betriebspunkt entspricht, vorgenommen werden.In Another embodiment of the invention, the electric actuator with a device which outputs a feedback signal. This feedback signal gives the instantaneous position of the electric actuator again and it can thus an even faster approach to a certain position, the For example, an operating point corresponds to be made.
Der Steller ist bevorzugt kennlinien- oder kennfeldgesteuert, wobei die Kennlinien bzw. das Kennfeld durch stationäre Messungen, beispielsweise an einer Prüfstands-Brennkraftmaschine, ermittelt werden können. Sodann lässt sich die maximal zulässige Öffnung des Gasdruck-Regelventils lastabhängig aus einem solchen Kennfeld oder einer Kennlinie ableiten und bei Lastaufschaltungen kann ein Betrieb der Brennkraftmaschine an der Klopfgrenze zugelassen werden. Für jeden Betriebspunkt der Brennkraftmaschine gibt es somit eine maximal mögliche Anfettung des Gemisches, das mit zunehmender Last abnimmt. Erreicht wird somit eine Verkürzung der Ausregelzeit der Brennkraftmaschine bzw. eine Erhöhung der maximal möglichen Lastaufschaltung.Of the Controller is preferably characteristic or map-controlled, wherein the characteristic curves or the characteristic field by stationary measurements, for example on a test bench internal combustion engine, can be determined. Then lets the maximum permissible opening of the Gas pressure control valve load-dependent derived from such a map or a characteristic and at Lastaufschaltungen can be an operation of the internal combustion engine at the Knock limit are allowed. For Each operating point of the internal combustion engine, there is thus a maximum possible Enrichment of the mixture, which decreases with increasing load. Reached thus becomes a shortening the settling time of the internal combustion engine or an increase in the maximum possible Load application.
Bei Lastabschaltungen wird das maximal zulässige Schließen des Gasdruck-Regelventils wiederum lastabhängig aus einem Kennfeld oder einer Kennlinie abgeleitet und lässt somit einen Betrieb der Brennkraftmaschine an der Aussetzergrenze zu. Diese Grenze wird ebenfalls beispielsweise an einer Prüfstands-Brennkraftmaschine ermittelt. Für jeden Betriebspunkt der Brennkraftmaschine gibt es somit auch eine maximal mögliche Abmagerung des Gemisches. Auch in diesem Falle wird eine Verkürzung der Ausregelzeit der Brennkraftmaschine erreicht.at Load shuts off will be the maximum allowable closing of the Gas pressure control valve in turn load-dependent from a map or derived from a characteristic and leaves thus operation of the internal combustion engine at the misfire limit to. This limit also applies, for example, to a test-bench internal combustion engine determined. For every operating point of the internal combustion engine, there is also a maximum possible Emaciation of the mixture. Also in this case, a shortening of the settling time reaches the internal combustion engine.
