Description

Verfahren und Vorrichtung zum Öffnen und Schließen eines Ventils eines Verbrennungsmotors Method and device for opening and closing a valve of an internal combustion engine
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Öffnen und Schließen eines Ventils eines Verbrennungsmotors .The invention relates to a method and a device for opening and closing a valve of an internal combustion engine.
Bekannt sind die nockenwellengesteuerte Ventilbetätigung, die elektromagnetische und die hydraulische Ventilsteuerung. Die Erfindung geht im Prinzip von der elektromagnetischen Ventilsteuerung (EMVS) aus. Sie läßt sich aber auch im Zusammenhang mit anderen wie z. B. hydraulischen oder pneumatischen Ventilsteuerungen einsetzen.The camshaft-controlled valve actuation, the electromagnetic and the hydraulic valve control are known. The invention is based in principle on electromagnetic valve control (EMVS). But you can also in connection with others such. B. use hydraulic or pneumatic valve controls.
Bisher war die EMVS als Ein-Massen-Schwinger aufgebaut. Dabei kann ein Anker zwischen zwei Magnetspulen hin- und herschwingen. Der Anker ist mit dem Ventil verbunden. Im stromlosen Zustand befindet sich der Anker etwa in der Mitte zwischen den beiden Magnetspulen. Aufgrund der großen Spaltabstände in der Ruhelage und damit einhergehendem schlechten Wirkungsgrad ist bei der Beschleunigung ein unverhältnismäßig großer Energieaufwand nötig, der für sich genommen schon die Realisierbarkeit der EMVS in Serienanwendungen in Frage stellt.So far, the EMVS was built as a one-mass transducer. An armature can swing back and forth between two solenoids. The armature is connected to the valve. When de-energized, the armature is located approximately in the middle between the two solenoids. Due to the large gap distances in the rest position and the associated poor efficiency, a disproportionate amount of energy is required during acceleration, which in itself questions the feasibility of EMVS in series applications.
Ein weiterer Nachteil ist darin zu sehen, daß - um einen Kontakt des Ventils mit dem Kolben sicher zu verhindern - im Kolben Ventilnischen eingearbeitet sein müssen oder daß die Wand des Verbrennungsraums im Zylinderkopf zurückgesetzt sein muß. Diese Maßnahmen stellen verbrennungstechnisch eine negative Beeinflussung des Brennraums dar. Die Erfindung beschäftigt sich daher mit dem Problem, bei elektromagnetischen oder hydraulischen Ventilsteuerungen den Energieeinsatz zu reduzieren und eine negative Beeinflussung des Verbrennungsvorgangs durch Ventilnischen oder zurückgesetzte Brennraumwände am Zylinderkopf zu vermeiden.Another disadvantage is that - in order to reliably prevent contact of the valve with the piston - valve niches must be incorporated in the piston or that the wall of the combustion chamber in the cylinder head must be set back. In terms of combustion technology, these measures have a negative impact on the combustion chamber. The invention is therefore concerned with the problem of reducing the use of energy in the case of electromagnetic or hydraulic valve controls and avoiding a negative influence on the combustion process by valve niches or recessed combustion chamber walls on the cylinder head.
Dieses Problem wird bei gattungsgemäßen Verfahren gelöst durch die kennzeichnenden Merkmale des Anspruchs 1. Bei gattungsgemäßen Vorrichtungen wird das Problem gelöst durch die kennzeichnenden Merkmale der Ansprüche 4 oder 5. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche .This problem is solved in generic methods by the characterizing features of claim 1. In generic devices, the problem is solved by the characterizing features of claims 4 or 5. Advantageous further developments are the subject of the dependent claims.
Grundgedanke der Erfindung ist es, die kinetische Energie des Ventils - und eines ggfs . mit dem Ventil verbundenen Masseteils - die dieses am Ende des Schließvorgangs aufweist, weitestgehend auf einen Massekörper zu übertragen und dort zwischenzuspeichern, sodaß diese Energie für den nächsten Öffnungshub des Ventils zur Verfügung steht. Dabei kann der Impuls jeweils direkt zwischen den Massekörpern übertragen oder über mindestens ein Zwischenglied weitergeleitet werden, wobei das Zwischenglied entweder weitgehend ortsfest angeordnet ist oder mit einer der beiden Massen verbunden ist. Die Zwischenspeicherung der Energie - wenn der Massekörper z. B. von einem Magnet festgehalten werden soll - erfolgt im Regelfall in einer Feder, die eine Rückstellkraft auf den Massekörper ausübt.The basic idea of the invention is to reduce the kinetic energy of the valve - and if necessary. to the mass part connected to the valve - which it has at the end of the closing process - largely to be transferred to a mass body and temporarily stored there, so that this energy is available for the next opening stroke of the valve. The impulse can in each case be transmitted directly between the mass bodies or passed on via at least one intermediate link, the intermediate link either being largely stationary or being connected to one of the two masses. The intermediate storage of energy - when the mass body z. B. to be held by a magnet - usually takes place in a spring that exerts a restoring force on the mass body.
Physikalisch stellt die bekannte EMVS ein Ein-Masse-Pendel dar, während die Erfindung als Zwei-Massen-Pendel mit Energieübertragung beschreibbar ist.Physically, the well-known EMVS represents a one-mass pendulum, while the invention can be described as a two-mass pendulum with energy transfer.
Dabei wird die bekannte Ein-Masse-Schwingung der EMVS in zwei Halbschwingungen mit zwei Massen aufgeteilt. Am Ende jeder Halbschwingung erfolgt eine Übergabe der kinetischen Energie an die zweite schwingende Masse durch einen Stoßim- puls. Durch eine geeignete Abstimmung z. B. über die Federrate erreicht man, daß sich die Grund-Schwingungsdauer des Ventils im Verhältnis "drei Takte geschlossen" zu "ein Takt geöffnet" einstellt.The well-known one-mass vibration of the EMVS is divided into two half-vibrations with two masses. At the end of each half-vibration, the kinetic energy is transferred to the second vibrating mass by an impact Pulse. By a suitable vote z. B. via the spring rate is achieved that the basic oscillation period of the valve in the ratio "three cycles closed" to "one cycle open" is set.
Eine Variation der Schwingzeiten kann also einerseits durch Verstellung der Federvorspannung und/oder der Federsteifig- keit und andererseits durch bekannte Mittel wie magnetisches Festhalten in den Endlagen realisiert werden.A variation of the oscillation times can thus be realized on the one hand by adjusting the spring preload and / or the spring stiffness and on the other hand by known means such as magnetic retention in the end positions.
Verglichen mit der bekannten EMVS ergeben sich die folgenden Vorteile:Compared to the known EMVS, the following advantages result:
- Das Ventil bleibt ohne äußere Energiezufuhr geschlossen, da im geschlossenen Zustand die energetische Nullage vorliegt. Erforderlichenfalls kann es auch durch Federkraft in den Ventilsitz gepreßt werden.- The valve remains closed without external energy supply, since the energetic zero position is present in the closed state. If necessary, it can also be pressed into the valve seat by spring force.
- Undefinierte Betriebspunkte werden vermieden, da es im Ventilbewegungszyklus eine eindeutige Ruhelage gibt .- Undefined operating points are avoided because there is a clear rest position in the valve movement cycle.
- Das Einschwingen verläuft kontrolliert, ein Kontakt des Ventils mit dem Kolben kann ausgeschlossen werden. Daher kann der Brennraum optimal - insbesondere ohne Ventilnischen - gestaltet werden.- The swinging is controlled, contact of the valve with the piston can be excluded. The combustion chamber can therefore be optimally designed - especially without valve niches.
- Durch die impulsartige Übertragung werden sehr steile Öffnungsflanken bzw. wird ein sehr schnelles Öffnen des Ventils ermöglicht.- The impulse-like transmission enables very steep opening flanks or a very quick opening of the valve.
- Die Ventilöffnungsdauer kann über eine Änderung der Federvorspannung variiert werden.- The valve opening duration can be varied by changing the spring preload.
Die Erfindung wird im folgenden anhand eines Beispiels näher beschrieben. Es zeigt:The invention is described in more detail below using an example. It shows:
Fig. 1 eine erfindungsgemäße Vorrichtung zur Betätigung eines Ventils im Ruhezustand Fig. 2 ein Ablaufdiagramm eines erfindungsgemäßen Verfahrens .Fig. 1 shows an inventive device for actuating a valve in the idle state Fig. 2 is a flow diagram of a method according to the invention.
Das System ist in Fig. 1 im Ruhezustand dargestellt.The system is shown in Fig. 1 in the idle state.
Eine Ventil 1 und eine mit dem Ventil 1 durch ein Gewinde verbundene Masse 1' sowie eine Masse 2 können ihre kinetische Energie bzw. ihren Impuls über ein Zwischenglied 3 austauschen, das mit der Masse 2 (m2) fest verbunden ist.A valve 1 and a mass 1 'connected to the valve 1 by a thread and a mass 2 can exchange their kinetic energy or their impulse via an intermediate member 3 which is firmly connected to the mass 2 (m2).
Zur Begrenzung der Bewegung der Masse 1' bzw. des mit Masse 1 ' verbundenen Ventils 1 ist der mit dem nicht dargestellten Zylinderkopf verbundene Sitzring 4 und für Masse 2 ein Anschlag 5 vorgesehen. Die Position des Anschlags 5 ist so festgelegt bzw. einstellbar, daß in allen Betriebszuständen das Ventil geschlossen werden kann. Die Vorspannkraft der Feder 6 wird mit Hilfe der verstellbaren Auflage 8 größer eingestellt als die Kraft der Feder 7 mit der Auflage 9, um im Ruhezustand das sichere Schließen des Ventils zu gewährleisten. Das Beschleunigen, Verzögern und Halten in Endposition der Massen 1' (ml) und 2 (m2) erfolgt mittels Elektromagneten 10 (Ml) und 11 (M2).To limit the movement of the mass 1 'or the valve 1 connected to mass 1', the seat ring 4 connected to the cylinder head (not shown) and a stop 5 for mass 2 are provided. The position of the stop 5 is fixed or adjustable so that the valve can be closed in all operating states. The prestressing force of the spring 6 is set greater with the help of the adjustable support 8 than the force of the spring 7 with the support 9 in order to ensure the safe closing of the valve in the idle state. Accelerating, decelerating and holding in the end position of the masses 1 '(ml) and 2 (m2) is carried out by means of electromagnets 10 (Ml) and 11 (M2).
Verglichen mit bekannten elektromagnetischen Aktuatoren zur Ventilsteuerung besteht zwischen dem Ventil 1 und dem Betätigungsglied für das Ventil, also der Masse m , keine Verbindung, beide sind voneinander getrennt, wobei die Trennung in Fig. 1 zwischen dem Gewindebeginn des Ventils und dem Zwischenglied 3 vorliegt.Compared to known electromagnetic actuators for valve control, there is no connection between the valve 1 and the actuating element for the valve, that is to say the mass m, the two are separated from one another, the separation in FIG. 1 being between the start of the thread of the valve and the intermediate element 3.

Durch die erfindungsgemäße Ventilsteuerung kann die maximale Leistungsaufnahme der Elektromagneten erheblich vermindert werden, da im Bereich großer Spaltabstände zwischen Magnet und vom Magnet angezogenem Bauteil die Wiederverwertung der kinetischen Energie einen Großteil der sonst erforderlichen elektrischen Energie einspart. The maximum power consumption of the electromagnets can be considerably reduced by the valve control according to the invention, since the recycling of the kinetic energy saves a large part of the otherwise required electrical energy in the area of large gap distances between the magnet and the component attracted by the magnet.
