Description
Die Erfindung betrifft ein Verfahren zum Betreiben einer Brennkraftmaschine nach der im Oberbegriff von Anspruch 1 näher definierten Art. Des weiteren betrifft die Erfindung eine Vorrichtung zur Durchführung des Verfahrens gemäß dem Oberbegriff von Anspruch 4 sowie eine Brennkraftmaschine.The The invention relates to a method for operating an internal combustion engine according to the closer defined in the preamble of claim 1. Art the invention relates to a device for carrying out the Method according to the preamble of claim 4 and an internal combustion engine.
Ein
gattungsgemäßes Verfahren
und eine entsprechende Vorrichtung zur Durchführung desselben sind aus der
Dabei kann jedoch der aus dem vorherigen Arbeitsspiel in dem Volumen zwischen dem zusätzlichen Steuerelement und dem Einlassventil eingeschlossene, relativ hohe Unterdruck Probleme verursachen. Zum einen werden bei der Öffnung des zusätzlichen Steuerelements Unterdruckwellen im Einlasskanal ausgelöst, welche zu einer verstärkten Schallabstrahlung im Ansaugbereich der Brennkraftmaschine führen können. Insbesondere bei Brennkraftmaschinen mit mehreren Zylindern kann diese unerwünschte Dynamik innerhalb der Ansauganlage zu starken Schwankungen des Restgasgehalts in den Zylindern führen und es ist aus diesem Grund unter Umständen nicht möglich, die für einen optimalen Betrieb der Brennkraftmaschine erforderlichen, hohen Restgasgehalte einzustellen.there However, the difference between the previous work cycle in the volume the additional Control and the inlet valve included, relatively high Cause negative pressure problems. For one thing, at the opening of the additional Control vacuum waves in the inlet channel triggered, which to an increased sound radiation can lead in the intake of the internal combustion engine. Especially with internal combustion engines with multiple cylinders, this undesirable dynamics within the Intake system to strong fluctuations in the residual gas content in the cylinders to lead and it may not be possible for one optimal operation of the internal combustion engine required, high residual gas contents adjust.
Andererseits ist die Dichtheit dieses Steuerelements und der dadurch entstehende Unterdruck jedoch bei einer anderen, mit einer ein solches zusätzliches Steuerelement in dem Einlasskanal aufweisenden Brennkraftmaschine durchführbaren Betriebsart, nämlich der Impulsaufladung, notwendig, um die bei diesem Verfahren gewünschte Steigerung des Mitteldrucks erreichen zu können.on the other hand is the tightness of this control and the resulting However, negative pressure in another, with one such additional Control in the intake passage having internal combustion engine feasible Operating mode, namely the impulse charging, necessary to increase the desired in this process increase the To reach medium pressure.
Es ist daher Aufgabe der vorliegenden Erfindung, ein Verfahren und eine Vorrichtung zum Betreiben einer Brennkraftmaschine zu schaffen, bei welchen die Brennkraftmaschine sowohl in einem Laststeuerverfahren mit frühem Einlassschluss als auch in einem Impulsaufladeverfahren betrieben werden kann, wobei eine erhöhte Schallabstrahlung durch das Öffnen und Schließen des zusätzlichen Steuerelements vermieden werden und sich keine gegenseitige Beeinflussung der Ansaugströmungen in den Einlasskanälen bei mehrzylindrigen Brennkraftmaschinen ergeben soll.It is therefore an object of the present invention, a method and to provide an apparatus for operating an internal combustion engine, in which the internal combustion engine both in a load control method with early Inlet closure operated as well as in a pulse charging process can be, with an increased Sound emission by opening and closing of the additional Control are avoided and no mutual interference the intake flows in the inlet channels should result in multi-cylinder internal combustion engines.
Erfindungsgemäß wird diese Aufgabe durch das in Anspruch 1 beschriebene Verfahren gelöst.According to the invention this Problem solved by the method described in claim 1.
Durch die erfindungsgemäße Belüftung des Volumens zwischen dem Steuerelement und dem Brennraum während der Geschlossenstellung des Steuerelements wird die Erzeugung eines unerwünscht hohen Unterdrucks vermieden bzw. es wird derselbe ganz oder teilweise abgebaut, sodass sich die ansonsten aus einem solchen Unterdruck ergebenden, nachteiligen Effekte, wie unerwünschte Schwingungen in der Ansaugleitung und die dadurch entstehenden akustischen Probleme und Differenzen im Restgasgehalt, nicht einstellen.By the ventilation of the volume according to the invention between the control and the combustion chamber during the closed position the control will generate an undesirably high level Vacuum avoided or it is the same whole or in part degraded, so that otherwise from such a negative pressure resulting adverse effects, such as unwanted vibrations in the Suction line and the resulting acoustic problems and differences in the residual gas content, do not stop.
Vorzugsweise wird das erfindungsgemäße Verfahren während eines Teillastbetriebs der Brennkraftmaschine durchgeführt, da in diesem Fall die Belüftung des Volumens zwischen dem Steuerelement und dem Brennraum keinen negativen Effekt zur Folge hat und gerade im Teilastbetrieb bei der Durchführung des Laststeuerverfahrens mit frühem Einlassschluss die oben beschriebenen Nachteile auftreten würden.Preferably becomes the method according to the invention while a partial load operation of the internal combustion engine performed since in In this case, the ventilation the volume between the control and the combustion chamber no negative effect and especially in partial load operation the implementation of the load control method with early Inlet closure would occur the disadvantages described above.
Wenn in einer vorteilhaften Weiterbildung der Erfindung bei niedriger Last der Brennkraftmaschine die Zufuhr von Luft in den Brennraum über die Belüftung des Volumens in dem Einlasskanal gesteuert wird, so kann auf ein Umschalten des in dem Einlasskanal angeordneten, zusätzlichen Steuerelements verzichtet werden, sodass der hierfür ansonsten erforderliche Strombedarf nicht anfällt und in diesem Betrieb der Brennkraftmaschine eine zusätzliche Kraftstoffeinsparung erreicht werden kann. Des weiteren wird hierdurch der Verschleiß und eine eventuelle Geräuschentwicklung des Steuerelements vermieden. Hierbei ist lediglich der Energiebedarf zur Steuerung der Belüftung erforderlich.If in an advantageous embodiment of the invention at low Load of the internal combustion engine, the supply of air into the combustion chamber via the ventilation The volume is controlled in the intake passage, so can on Switching the arranged in the inlet duct, additional Control are omitted, so the otherwise for this required power is not required and in this operation the Internal combustion engine an additional fuel saving can be achieved. Furthermore, this is the wear and a possible noise of the control avoided. Here is only the energy needs to control the ventilation required.
Eine Vorrichtung zur Durchführung des Verfahrens ist in Anspruch 4 angegeben.A Apparatus for carrying out of the method is given in claim 4.
Durch die erfindungsgemäße Belüftungsleitung mit der Ventileinrichtung kann das Volumen zwischen dem Steuerelement und dem Brennraum in einfacher Weise belüftet werden, wozu lediglich ein sehr geringer konstruktiver Aufwand erforderlich ist.By the ventilation line according to the invention with the valve means, the volume between the control and the combustion chamber are ventilated in a simple manner, what only a very low design effort is required.
Eine Brennkraftmaschine mit einer erfindungsgemäßen Vorrichtung ist in Anspruch 13 angegeben.A Internal combustion engine with a device according to the invention is required 13 indicated.
Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den restlichen Unteransprüchen so- wie aus den nachfolgend anhand der Zeichnung prinzipmäßig dargestellten Ausführungsbeispielen.Further advantageous embodiments and modifications of the invention will become apparent from the remaining subclaims as well as from the following Gend based on the drawing in principle illustrated embodiments.
