Luftverdichtende, direkteinspritzende BrennkraftmaschineAir-compressing, direct-injection internal combustion engine

Die Erfindung bezieht sich auf eine luftverdichtende, direkteinspritzende Brennkraftmaschine mit einem im Kolbenboden oder Zylinderkopf angeordneten, rotqtionskörperförmigen Brennraum und einer mittig oder nahezu mittig zu diesem im Zylinderkopf vorgesehenen Kraftstoff-Einspritzdüse.The invention relates to an air-compressing, Direct-injection internal combustion engine with a rotary body-shaped, arranged in the piston head or cylinder head Combustion chamber and a central or almost central to this provided in the cylinder head fuel injection nozzle.

Derartige Brennkraftmaschinen sind bereits seit vielen Jahren in den verschiedensten Varianten bekannt. Um die in den Zylindern bzw. Brennräumen komprimierte Verbrennungsluft möglichst vollständig auszunützen, weisen dabei die Kraftstoff-Einspritzdüsen mehrere, insbesondere zwischen 3 und 8 Düsenbohrungen auf, durch die der Kraftstoff weitgehend gleichmäßig im Brennraum und damit in der Verbrennungsluft verteilt werden. Die Anzahl der Düsenbohrungen ist jedoch sowohl aus Festigkeitsgründen als auch aus Gründen des Verkokens, welches um so stärker auftritt, je geringer der Querschnitt ist, begrenzt.Such internal combustion engines have been around for many Years known in the most diverse variants. To the compressed in the cylinders or combustion chambers To use combustion air as completely as possible, the fuel injection nozzles have several, in particular between 3 and 8 nozzle bores through which the fuel is largely uniform in the combustion chamber and thus distributed in the combustion air. the The number of nozzle bores is, however, both for reasons of strength and for reasons of coking, which the more it occurs, the smaller the cross-section, limited.

Um die Gemischbildung welter zu verbessern, wird die Verbrennungsluft vielfach in eine Drehbewegung versetzt, die in der Regel durch Ausbildung des Ansaug-In order to improve the mixture formation, the Combustion air is often set in a rotary motion, which is usually caused by the formation of the intake

kanals als Drallkanal oder durch ein Schirmventil erzeugt wird. Hierdurch erhöht sich allerdings die Gaswechselarbeit und es erfolgt eine Verminderung der angesaugten Frischluftmenge. Hinzu kommt, daß die erhöhte Geschwindigkeit der Verbrennungsgase zu einem verstärkten Wärmeübergang von den Verbrennungsgasen an die den Brennraum begrenzenden Bauteile und damit zu erhöhten Wärmeverlusten und größeren thermischen Belastungen der Bauteile führt.channel generated as a swirl channel or by an umbrella valve will. However, this increases the gas exchange work and there is a reduction in the intake of fresh air. In addition, the increased speed of the combustion gases to one increased heat transfer from the combustion gases to the components delimiting the combustion chamber and thus leads to increased heat losses and greater thermal loads on the components.

Schließlich weisen die üblicherweise verwendeten Lochdüsen noch den Nachteil auf, daß während der Öffnungsund Schließphase im Dichtsitz zum Teil sehr hohe Drosselverluste entstehen, was zu einem starken Druckabfall im Kraftstoff vor den Austrittsöffnungen führt und damit die Kraftstoff Strahlaufbereitung erheblich verschlechtert. Die Folgen sind schlechter Kaltstart und hohe Emission von Produkten unvollständiger Verbrennung.Finally, the hole nozzles commonly used have the disadvantage that during the opening and Closing phase in the sealing seat, sometimes very high throttle losses occur, which leads to a sharp drop in pressure in the fuel leads in front of the outlet openings and thus significantly worsens the fuel jet preparation. The consequences are poor cold starts and high emissions of incomplete combustion products.

Hier setzt bereits die Erfindung ein, der die Aufgabe zugrunde liegt, die genannten Nachteile zu vermeiden und eine Brennkraftmaschine der eingangs beschriebenen Art dahingehend zu verbessern, daß der Kraftstoff so gleichmäßig in die Verbrennungsluft eingespritzt wird, daß allein durch die Quetschströmung der Verbrennungsluft eine nahezu vollkommen gleichmäßige Vermischung mit dieser erfolgt, so daß der genannte Luftdrall auf ein Minimum reduziert werden oder sogar ganz entfallen kann.This is where the invention begins, which is based on the object of avoiding the disadvantages mentioned and an internal combustion engine of the type described above To improve the way that the fuel is injected so evenly into the combustion air, that just by the squeezing flow of the combustion air an almost completely even mixing takes place with this, so that the air swirl mentioned can be reduced to a minimum or even eliminated entirely can.

Nach der Erfindung wird die Aufgabe dadurch gelöst, daß die Kraftstoff-Einspritzdüse eine in Richtung zum Brennraum hin öffnende, mit einer konischen Dichtfläche versehene Düsennadel aufweist, daß der Dicht-According to the invention, the object is achieved in that the fuel injection nozzle in one direction has a nozzle needle which opens towards the combustion chamber and is provided with a conical sealing surface, so that the sealing

sitz gleichzeitig die Austrittsöffnung bildet und der jeweils freie Querschnitt dem Kraftstoff-Austrittsquerschnitt entspricht, und daß der Kraftstoff derart in Form eines Kegelmantels in den Brennraum eingespritzt wird, daß er die im Brennraum befindliche Luft in zwei nahezu gleiche Volumina teilt.sit at the same time forms the outlet opening and the each free cross-section of the fuel outlet cross-section corresponds, and that the fuel is injected into the combustion chamber in the form of a cone shell is that it divides the air in the combustion chamber into two almost equal volumes.

Durch diese Anordnung werden vor allem die während der öffnungs- und Schließphase der Einspritzdüse auftretenden Drosselverluste vor dem Austrittsquerschnitt vermieden, der Kraftstoff wird mit vollem Druck in den Brennraum eingspritzt und hier durch die Quetschwirbel, die beim Eintreten der Verbrennungsluft in den Brennraum entstehen, intensiv mit der gesamten vorhandenen Luft vermischt. Somit ist mit einer nahezu vollständigen Verbrennung und mit minimaler Emission von Produkten unvollständiger Verbrennung zu rechnen.This arrangement primarily eliminates those that occur during the opening and closing phases of the injection nozzle Throttling losses in front of the outlet cross-section are avoided, the fuel is fed into the combustion chamber at full pressure injected and here by the squeeze eddies that arise when the combustion air enters the combustion chamber, intensely mixed with all the air present. Thus, with an almost complete combustion and expect minimal emissions of incomplete combustion products.

Die erfindungsgemäße Anordnung arbeitet auch dann noch absolut einwandfrei, wenn die Längsachse der Kraftstoff-Einspritzdüse zur Brennraumlängsachse bis zu maximal 20° geneigt verläuft oder ihre Austrittsöffnung bis zu maximal 15 % des größten Brennraumdurchmessers außermittig zum Brennraum angeordnet ist.The arrangement according to the invention also works absolutely flawlessly when the longitudinal axis of the fuel injection nozzle is inclined up to a maximum of 20 ° to the longitudinal axis of the combustion chamber or its outlet opening is arranged eccentrically to the combustion chamber up to a maximum of 15% of the largest combustion chamber diameter.

Gemäß Fig. I weist ein Düsenkörper I an seinem freien Ende einen konisch nach außen verlaufenden Dichtsitz auf. Im DUsenkörper I ist eine Bohrung 3 für die Kraftstoffzufuhr vorgesehen, in der eine an ihrem freien Ende eine sich konisch erweiternde Dichtfläche 4 aufweisende Düsennadel 5 verschiebbar gelagert ist. Die Lagerung selbst befindet sich im Inneren der Einspritzdüse und wurde nicht dargestellt. In Fig. 1 befindet sich die Düsennadel 5 in geöffneter Stellung, in der der Kraftstoff in Form eines Kegelmantels 6 fein zerstäubt unmittelbar austritt.According to FIG. I, a nozzle body I has on its free End of a conical outwardly extending sealing seat. In the DUsenkkörper I is a hole 3 for the fuel supply provided, in which a conically widening sealing surface 4 having nozzle needle 5 is slidably mounted. The storage itself is located inside the injection nozzle and was not shown. In Fig. 1, the nozzle needle 5 is in the open position, in which the fuel in the form of a cone shell 6 exits finely atomized directly.

In den Fig. 2 bis 7 sind der Kolben einer Brennkraftmaschine jeweils mit 7, der Zylinderkopf mit 8, der Zylinder mit 9, die Kraftstoff-Einspritzdüse mit 10 und der Brennraum mit Il bezeichnet. In jeden der Brennräume Il wird der Kraftstoff in Form eines Kegelmantels 6 eingespritzt, wobei die Brennraumform und -Lage gleichgültig ist. Wichtig ist dabei lediglich, daß das Luftvolumen 12 über dem Kegelmantel 6 etwa gleich dem Luftvolumen 13 unterhalb desselben ist. Die strichlierte Linie 14 soll lediglich andeuten, daß der Kegelmantel 6 rund um den Brennraum Il etwa in einer Ebene endet, wobei der Kraftstoff durchaus nicht bis an die Brennraumwand gelangen muß. Die Längsachse der Kraftstoff-Einspritzdüse 10 schließlich ist mit χ und die Brennraumlängsachse mit y bezeichnet.In Figs. 2 to 7, the piston of an internal combustion engine are each with 7, the cylinder head with 8, the Cylinder with 9, the fuel injection nozzle with 10 and the combustion chamber with II. In each of the Combustion chambers II, the fuel is injected in the form of a conical shell 6, the shape of the combustion chamber and -Location is indifferent. It is only important that the volume of air 12 over the conical surface 6 is approximately is equal to the volume of air 13 below the same. The dashed line 14 is only intended to indicate that the cone shell 6 ends around the combustion chamber II approximately in one plane, the fuel being quite does not have to reach the combustion chamber wall. Finally, the longitudinal axis of the fuel injector 10 is with χ and the longitudinal axis of the combustion chamber with y.
