Description
Die Erfindung bezieht sich auf eine Klappenventil-Steuerung für eine Verbrennungskraftmaschine.The The invention relates to a flap valve controller for an internal combustion engine.
Ventilsteuerungen für Verbrennungskraftmaschinen sind bisher nahezu ausnahmslos über Nockenwellen betätigte Tellerventile. Die an der Drehzahl des Motors gekoppelte Betätigung der Ventile hat jedoch zum einen den Nachteil, dass diese der Motorcharakteristik genau entgegen läuft, da bei niedrigen Drehzahlen die Ventile relativ lange Zeit und bei hohen Drehzahlen eine kürzere Zeit geöffnet sind. Umgekehrt wäre es sinnvoller.valve controls for internal combustion engines have so far almost without exception Camshafts actuated Poppet valves. The coupled to the speed of the engine actuation of However, valves has the disadvantage that they have the engine characteristics runs exactly contrary, because at low speeds the valves are relatively long time and at high speeds a shorter one Time are open. Vice versa would be it makes more sense.
Zum zweiten bewirken die großen Ventilöffnungszeiten bei niedrigen Drehzahlen, dass die Einströmgeschwindigkeit des Frischgases klein bleibt und somit nur wenig die Gemischaufbereitung unterstützt wird. Dadurch bleibt die Kraftstoffausbeute unvollständig und der Verbrauch unnötig höher.To the second effect the big ones Valve opening times at low speeds that the inflow velocity of the fresh gas remains small and thus little the mixture preparation is supported. As a result, the fuel yield remains incomplete and consumption unnecessarily higher.
Beidem versucht man bisher dadurch zu begegnen, dass man für die Teillast den Ventilhub reduziert oder auch den Ansaugquerschnitt verringert. Das kann in Stufen oder auch vollvariabel erfolgen.In which you try to counter so far by that for the partial load reduces the valve lift or reduces the intake cross section. The can be done in steps or fully variable.
Die Teillastverbräuche von mit solchen Technologien ausgerüsteten saugrohreinspritzenden Motoren (Motoren mit äußerer Gemischbildung) werden dadurch günstiger.The Partial load consumption of sucrose injector equipped with such technologies Engines (engines with external mixture formation) become cheaper.
Für Motoren mit direkter Kraftstoffeinspritzung und innerer Gemischbildung ist es jedoch nicht nur wichtig, dass die in den Zylinder einströmende Frischluft eine hohe Strömungsgeschwindigkeit hat, sondern diese sollte auch noch für einen guten Drall im Zylinder sorgen und damit für eine gute Gemischaufbereitung.For engines with direct fuel injection and internal mixture formation However, it is not only important that the incoming fresh air into the cylinder a high flow velocity has, but this should also for a good twist in the cylinder take care and thus for a good mixture preparation.
Das
versucht man zur Zeit mit Spiraleinlasskanälen und/oder Schrägkanälen zu erreichen,
wie dies z.B. in der
Nach wie vor fehlt es an einer Ventilsteuerung, die insbesondere die Gemischaufbereitung bei Motoren mit direktem Kraftstoffeinlass verbessert.To As before, it lacks a valve timing, in particular the Mixture preparation improved for engines with direct fuel inlet.
Bei der im folgenden beschriebenen variablen Ventilsteuerung handelt es sich um ein elektromagnetisch gesteuertes Klappenventil.at is the variable valve timing described below it is an electromagnetically controlled flap valve.

Die Funktionsweise des Ventils geht aus der einzigen Figur hervor, in welcher ein mit einem solchen Ventil ausgerüsteter Zylinderkopf dargestellt ist.The Operation of the valve is evident from the single figure, in which represents a equipped with such a valve cylinder head is.

Mit einem solchermaßen betätigten Einlassventil wird das im Stand der Technik formulierte technische Problem gelöst. Die Ventilsteuerung vermag es, einen weitaus kräftigeren Drall im Zylinder zu erzeugen als das mit Spiral- und Schrägkanälen möglich ist und hat den weiteren Vorteil, dass der erhaltene Drall nicht noch mit Strömungsverlusten erkauft wird.With in such a way actuated Inlet valve is the formulated in the prior art technical Problem solved. The valve control is capable of a much more powerful twist in the cylinder to generate than with spiral and oblique channels is possible and has the other Advantage that the swirl obtained not even with flow losses is bought.
