Description
Die Erfindung betrifft eine Resonanz-Ansaugeinrichtung für einen Mehtzylinder-Verbxennungsmotor, bei der die die einzelnen Zylinder mit Luft oder Gemisch beschickenden Leitungen über Hilfeleitungen verbunden sind, die eine verbesserte ZylinderfUllung ermöglichen.The invention relates to a resonance intake device for a multi-cylinder combustion engine, in which the lines supplying the individual cylinders with air or mixture are connected via auxiliary lines which enable improved cylinder filling.
Bei Resonanz-Ansaugeinrichtungen von Verbrennungsmotoren wird die Wirkung von Druckwellen ausgenützt/ um die Zylinderfüllung bei bestimmten Motordrehzahlen zu steigern. Auf diese Weise erhält man einen höheren Füllungsgrad und daher eine Steigerung des vom Motor gelieferten Drehmoments.Resonance intake systems in internal combustion engines use the effect of pressure waves to increase cylinder filling at certain engine speeds. This results in a higher filling level and therefore an increase in the torque delivered by the engine.
Die Leitungen und eventuell die Leistungen von Resonanzeinrichtungen werden so bemessen (abgestimmt), daß die Eigenschwingungszeit der Einrichtung mit der Zeitspanne zwischen zwei bei bestimmten Drehzahlen aufeinanderfolgenden Einlaßtakten übereinstimmt. Wird daher das Schließen der Einlaßventile genau in dem Augenblick gesteuert, in dem sie die Druckwelle erreicht und der Druck an seinem Höhepunkt ist, so lassen sieh eine beträchtliche Steigerung der Zylinderfüllung sowie eine Schwungaufladung erzielen.The lines and possibly the power of resonance devices are dimensioned (tuned) so that the natural oscillation time of the device corresponds to the time between two intake strokes that follow one another at certain speeds. If the closing of the intake valves is therefore controlled at the exact moment when it reaches the pressure wave and the pressure is at its peak, a considerable increase in cylinder filling and a dynamic boost can be achieved.
Aufgabe der Erfindung ist es, eine Einrichtung zu schaffen, mit der die Füllung eines jeden Zylinders dadurch gesteigert wird, daß sich die Resonanzwirkung der jeweiligen Axisaug leitung mit der Resonanzwirkung von wenigstens einer Ansaugleitung der anderen zylinder summiert.The object of the invention is to create a device with which the filling of each cylinder is increased by the resonance effect of the respective axial intake line being added to the resonance effect of at least one intake line of the other cylinders.
Dadurch erzielt man bei.jedem Zylinder eine auf die kombinierte Wirkung.der in der entsprechenden Leitung während des Einlasstaktee anwesenden Druckwellen und der Druckwellen, die gleichzeitig in den Ansaugleitungen der anderen Zylinder anwesend sind, die den Einlasstakt vor dem betreffenden Zylinder durchgeführt haben.This allows each cylinder to achieve a response to the combined effect of the pressure waves present in the corresponding line during the intake stroke and the pressure waves present simultaneously in the intake lines of the other cylinders that have completed the intake stroke before the cylinder in question.
Bei einer Ausführungsform sind samtIiehe Ansaugleitungen der einzelnen Zylinder je über eine Hilfsleitung miteinander verbunden. Bei einer weiteren Ausführungsform sind die Ansaugleitungen der einzelnen zylinder über entsprechende Hilfsleitungen gruppenweise miteinander verbunden.In one embodiment, all intake lines of the individual cylinders are connected to one another via an auxiliary line. In another embodiment, the intake lines of the individual cylinders are connected to one another in groups via corresponding auxiliary lines.

In Fig. 1 ist ein mit 10 bezeichneter Vierylinder-fceihenverbrennungsiAötor schematisch dargestellt. Mit 11, 12, 13, 14 sind die zylinder und mit 15, 16, 17, 18 die entsprechenden Resonanzleitungen bezeichnet, die die Zylinder mit Luft öder Gemisch beschicken. Me AasSrttgleitungen sind mit eigenen, mit 19, 20, 21, 22 bezeichneten Drosselklappen versehen, die mit dem nicht dargestellten Gaspedal in Verbindung stehen.In Fig. 1, a four-cylinder flat-fuel combustion engine is shown schematically, designated 10. The cylinders are designated 11, 12, 13, 14 and the corresponding resonance lines, which supply the cylinders with air or mixture, are designated 15, 16, 17, 18. The exhaust lines are provided with their own throttle valves, designated 19, 20, 21, 22, which are connected to the accelerator pedal (not shown).
Mit 23 ist der Luftfilter bezeichnet, von dem sich die einzelnen Leitungen 15, 16, 17, 18 abzweigen, und mit 24 ist die Ansaughut ze bezeichnet, die die Luft zum Filter fördert.23 designates the air filter, from which the individual lines 15, 16, 17, 18 branch off, and 24 designates the intake hood, which conveys the air to the filter.
Die Leitungen 15, 16, 17, 18 sind je mit einet Hilfsleitung 25, 26/ 27 bzw. 28 versehen, die über das mit 29 bezeichnete Kreuzstück miteinander verbunden sind.The lines 15, 16, 17, 18 are each provided with an auxiliary line 25, 26/ 27 or 28, which are connected to each other via the crosspiece marked 29.
In diesem besonderen Fall zweigen sich die Hilfsleitungen von den jeweiligen Resonanzleitungen vor den eigenen Drossel« klappen ab und weisen einen Durchmesser auf, der das 0,2-bls 0,5-Fache des Durchmessers der Resonanzleitungen beträgt.In this particular case, the auxiliary lines branch off from the respective resonance lines in front of their own throttle valves and have a diameter that is 0.2 to 0.5 times the diameter of the resonance lines.
Schliesslieh sind 30/ 31, 32/ 33 die Auspuffleitungen der Zylinder bezeichnet.Finally, 30/ 31, 32/ 33 designate the exhaust pipes of the cylinders.
Mit der beschriebenen Ansauganlage lässt sich bei Volleistungsbetrieb, in den höheren Drehzahlbereichen und bei ganz offenen Drosselklappen eine Steigerung des vom Motor gelieferten Drehmoments erzielen/ weil sich die Drudksteigerungs- und die Sehwungaufladungswirkungen, die auf die Druckwellen in der Leitung/ die sich im Einlasstakt befindet/ zurückzuführen sind, mit denselben Wirkungen kombinieren, die auf die Druckwellen der Leitungen zurückzuführen sind, die sieh vorher im Einlasstakt befanden.With the intake system described, an increase in the torque delivered by the engine can be achieved at full power, in the higher speed ranges and with the throttle valves fully open, because the pressure increase and the turbocharging effects due to the pressure waves in the line located in the intake stroke are combined with the same effects due to the pressure waves in the lines that were previously in the intake stroke.
Sei der Ausführungsform nach Fig. 2 sind die Ansaugleitungen 15 und 18 über die Hilfsleitung 34 und die Ansaugleitungen 16 und 17 über die Hilfsleitung 35 miteinander verbunden. In the embodiment according to Fig. 2, the intake lines 15 and 18 are connected to one another via the auxiliary line 34 and the intake lines 16 and 17 are connected to one another via the auxiliary line 35.
In diesem Fall sind also die Ansaugleitungen der Zylinder um 360° in der Ansaugfolge versetzt miteinander verbunden, die Arbeitsweise der Anlage ist jedoch dieselbe der Anlage nach Fig. 1.In this case, the intake lines of the cylinders are connected to each other offset by 360° in the intake sequence, but the operation of the system is the same as that of the system shown in Fig. 1.
