Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Einspritzen von Kraftstoff in einen Brennraum eines Zylinders einer Brennkraftmaschine und zur Betätigung wenigstens eines Gaswechselventils der Brennkraftmaschine.The The invention relates to a device for injecting fuel in a combustion chamber of a cylinder of an internal combustion engine and for operation at least one gas exchange valve of the internal combustion engine.
Derartige Einspritzvorrichtungen mit entsprechenden Einspritzventilen und Einspritzpumpen sind aus dem allgemeinen Stand der Technik in den verschiedensten Ausführungsformen bekannt. Obwohl gerade Einspritzsysteme in den letzten Jahren eine rasante Entwicklung hinter sich haben, die wesentlich zur Verbreitung der Direkteinspritzung mit hohem Druck beigetragen hat, besteht noch immer der Wunsch nach einer höheren Dynamik und einer größeren Variationsmöglichkeit des Ein spritzdrucks während der Einspritzung, um verschiedene, in jüngster Zeit entwickelte Einspritzverfahren realisieren zu können.such Injectors with corresponding injectors and Injection pumps are from the general state of the art in the various embodiments known. Although just injection systems in recent years, a rapid Development that has been essential to the dissemination of Direct injection with high pressure has still existed always the desire for a higher one Dynamics and a greater possibility of variation the injection pressure during Injection to various recently developed injection methods to be able to realize.
Aus
der
Es ist Aufgabe der vorliegenden Erfindung, eine Vorrichtung zum Einspritzen von Kraftstoff in einen Brennraum eines Zylinders einer Brennkraftmaschine und zur Betätigung wenigstens eines Gaswechselventils der Brennkraftmaschine zu schaffen, die ein hochdynamisches und sehr variables Einspritzen von Kraftstoff in den Brennraum und eine gleichzeitige Betätigung des wenigstens einen Gaswechselventils ermöglicht.It It is an object of the present invention to provide a device for injecting of fuel in a combustion chamber of a cylinder of an internal combustion engine and for exercise to provide at least one gas exchange valve of the internal combustion engine, the a highly dynamic and very variable injection of fuel into the combustion chamber and a simultaneous actuation of the at least one Gas exchange valve allows.
Erfindungsgemäß wird diese Aufgabe durch die in Anspruch 1 genannten Merkmale gelöst.According to the invention this Problem solved by the features mentioned in claim 1.
Durch die gleichzeitige Beaufschlagung des wenigstens einen Einspritzventils und des wenigstens einen Gaswechselventils der Brennkraftmaschine durch die wenigstens eine Förderpumpe ergeben sich sehr vorteilhafte Synergieeffekte, da auf eine große Anzahl bislang erforderlicher Bauteile, wie beispielsweise Regelventile und dergleichen, verzichtet werden kann, was zu erheblichen Einsparmöglichkeiten führt. Des weiteren kann durch die erfindungsgemäße Lösung auf eine ansonsten notwendige Ansteuer- bzw. Verstelleinrichtung, wie beispielsweise eine Nockenwelle oder einen Magnetaktuator, verzichtet werden, was eine erhebliche Kosten- und Bauraumeinsparung bedeutet. Des weiteren kann durch die Verwendung von Kraftstoff zur Steuerung des wenigstens einen Gaswechselventils auf ein zusätzliches Medium verzichtet werden.By the simultaneous admission of the at least one injection valve and the at least one gas exchange valve of the internal combustion engine through the at least one feed pump result in very advantageous synergy effects, as on a large number Previously required components, such as control valves and the like, can be dispensed with, resulting in significant savings leads. Furthermore, by the inventive solution to an otherwise necessary Control or adjusting device, such as a camshaft or a Magnetaktuator, be waived, which is a considerable Cost and space savings means. Furthermore, through the use of fuel to control the at least one Gas exchange valve on an additional Medium dispensed with.
Ein weiterer Vorteil besteht darin, dass das wenigstens eine Gaswechselventil mittels der Förderpumpe voll variabel und mit sehr hoher Dynamik, also mit einer sehr hohen Geschwindigkeit, verstellt werden kann, so dass neuartige Verbrennungsverfahren für Brennkraftmaschinen realisiert werden können, für welche die bislang eingesetzten Nockenwellen nicht geeignet sind.One Another advantage is that the at least one gas exchange valve by means of the feed pump fully variable and with very high dynamics, so with a very high Speed, can be adjusted, allowing novel combustion processes for internal combustion engines can be realized for which the previously used camshafts are not suitable.
Durch die erfindungsgemäße Auslegung der wenigstens einen Förderpumpe für einen mit hoher Frequenz intermittierend arbeitenden Förderbetrieb kann dieselbe voll variabel betrieben werden, wodurch zu jedem beliebigen Zeitpunkt ein annähernd beliebiger Kraftstoff- und somit Öffnungs- und Einspritzdruck eingestellt werden kann. In Verbindung mit der hohen Dynamik der erfindungsgemäßen Förderpumpe ermöglicht dies sowohl ein sehr schnelles Öffnen und Schließen des Einspritzventils als auch eine äußerst schnelle Verstellung des Einspritzdrucks, so dass neue Einspritz verfahren, die mit mehreren Druckvariationen während einer Einspritzung arbeiten, problemlos durchgeführt werden können.By the inventive design the at least one feed pump for one With high frequency intermittently working conveyor operation can the same full be operated variably, thereby at any time an almost arbitrary one Fuel and thus opening and injection pressure can be adjusted. In conjunction with the high dynamics of the feed pump according to the invention allows this is both a very fast opening and closing the injection valve as well as an extremely fast adjustment the injection pressure, so that new injection methods, with several Pressure variations during working an injection, can be performed easily.
Ein weiterer Vorteil der Verwendung einer derartigen Förderpumpe besteht darin, dass diese in den Zeitpunkten, in denen sie nicht gebraucht wird, ausgeschaltet bleiben kann, so dass eine erhebliche Energieeinsparung erreichbar ist. Des weiteren ermöglicht die erfindungsgemäße Lösung den Einsatz einer kleineren Förderpumpe, was gerade bei Brennkraftmaschinen ein großes Potenzial aufgrund des freigewordenen Bauraums bietet.One Another advantage of using such a feed pump is that these at times when they are not is needed, can stay switched off, allowing a significant energy saving is reachable. Furthermore, possible the solution of the invention the Use of a smaller pump, which has just become a great potential for internal combustion engines due to the vacant Construction space offers.
Als besonders gut geeignet zum Erzielen des mit hoher Frequenz intermittierend arbeitenden Förderbetriebs hat es sich erwiesen, wenn die wenigstens eine Förderpumpe mit piezoelektrischen, magnetostriktiven und/oder elektrochemischen Aktuatoren als Förderelementen ausgebildet ist.When particularly suitable for achieving the high frequency intermittent working production operation It has been found, if the at least one pump with piezoelectric, magnetostrictive and / or electrochemical actuators as conveying elements is trained.
Wenn des weiteren vorgesehen ist, dass sich in wenigstens einer von der Förderpumpe ausgehenden Druckleitung ein Umschaltventil zum Umschalten zwischen dem wenigstens einen Gaswechselventil und dem Einspritzventil befindet, so können sämtliche Gaswechselventile sowie das Einspritzventil eines Zylinders der Brennkraftmaschine mit ein und derselben Förderpumpe be trieben werden, wodurch sehr große Bauraum- und Kosteneinsparungen erzielbar sind.If is further provided that in at least one of the feed pump outgoing pressure line a switching valve to toggle between the at least one gas exchange valve and the injection valve is located, so can all Gas exchange valves and the injection valve of a cylinder Internal combustion engine with one and the same feed pump be operated, which is very big Space and cost savings can be achieved.
