Description

Brennkraftmaschine mit Wirbelkammer Brennkraftmaschinen, die mit Fremdzündung und äußerer oder innerer Gemischbildung arbeiten und die eine i@n Zylinderkopf ,seitlich vom Zylinder angeordnete Wirbelkammer aufweisen, deren Einströmkanal tangential zu ihrem Umfang angeordnet ist, sind bereits bekannt.Internal combustion engine with swirl chamber Internal combustion engines with spark ignition and external or internal mixture formation work and the one i @ n cylinder head, laterally have swirl chamber arranged by the cylinder, the inflow channel of which is tangential arranged to their perimeter are already known.

Die Erfindung sieht gegenüber dem bisher Bekannten eine Volumenverlagerung dadurch vor, daß die Wirbelkammer in Form einer Walze ausgebildet ist, die in der Mitte eine Einschnürung aufweist. Dabei befindet sich die Zündeinrichtung in an sich bekannter Weise an oder in der Nähe der Stelle der größten Strömungsgeschwindigkeit des einströmenden Gemisches.The invention provides a volume shift compared to the previously known characterized in that the swirl chamber is designed in the form of a roller which is in the Center has a constriction. The ignition device is on is known to be at or near the point of greatest flow velocity of the inflowing mixture.

Der sich hierdurch ,ergebende Vorteil besteht darin, daß der sonst kühlere Gemisehkern durch die Einschnürung etwa die gleiche Temperatur des umlaufenden Gemisches erhält und die Verdampfung der Brennstofftröpfchen durch die verbreiterte äußere Wandung der Wirbelkammer eine größere Verdampfungsfläche erhält bei sonst gleichem Inhadt der Verbrennungskammer und daß das Gemisch, da es nach außen verdrängt wird, zum schnelleren Kreisen gezwungen wird.The resulting advantage is that the otherwise cooler Gemisehkern due to the constriction about the same temperature of the circulating Mixture receives and the evaporation of the fuel droplets through the broadened the outer wall of the vortex chamber receives a larger evaporation area otherwise the same content of the combustion chamber and that the mixture, since it is displaced to the outside is forced to circle faster.

Die Erfindung wird in der Zeichnung durch drei Ausfü irungsbenspiele erläutert, und zwar zeigt Abb. 1 einen senkrechten Schnitt durch Zylinder mit Zylinderkopf, Abb. 2 einen waagerechten Schnitt durch die Wirbelkammer, während in Abb.3 die Wirbelkammer mit Kerzenhalterung und Auspuffventil im Schnitt dargestellt isst.The invention is shown in the drawing by three Ausfü irungsbenspiele explained, namely Fig. 1 shows a vertical section through cylinder with cylinder head, Fig. 2 shows a horizontal section through the vortex chamber, while in Fig.3 the vortex chamber with candle holder and exhaust valve shown in section.

Es bedeutet 1 die Zylinderwand, 2 den Zylinderkopf. 3 den Einführungskanal für das Brennstoff-Luft-Gemisch, 4 die Wandung der Wirbelkammer, 5 eine wahlweise anzubringende Ausnehmung für- das Gasgemisch, 6 die Zündkerzenhalterung und 7 das Innere der Wirbelkammer.It means 1 the cylinder wall, 2 the cylinder head. 3 the introduction channel for the fuel-air mixture, 4 the wall of the swirl chamber, 5 one optional Recess to be attached for the gas mixture, 6 the spark plug holder and 7 the Interior of the vortex chamber.

In den Abb. 2 und 3 isst mit 8 die Zündkerze und mit 9 das Auspuffventil bezeichnet.In Figs. 2 and 3, 8 is the spark plug and 9 is the exhaust valve designated.

Die Arbeitsweise der Maschine ist folgende: Beim Verdic'htu,ngshub wird das Gemisch in tangentialer Richtung durch den Einführungskanal 3 in die Wirbelkammer 4 gedrückt, wo es kreist und kurz vor Beendigung der Kompression gezündet wird. Das in der Ausnehmu.ng 5 vor der Zündkerze 6 befindliche Gemisch wird zuerst gezündet und die Flamme in Strömungsrichtuing in die Wirbelkammer 7 weitergetragen.The way the machine works is as follows: At Verdic'htu, ngshub the mixture is in the tangential direction through the introduction channel 3 into the vortex chamber 4 is pressed, where it circles and is ignited shortly before the end of the compression. The mixture located in the recess 5 in front of the spark plug 6 is ignited first and the flame is carried further into the vortex chamber 7 in the direction of flow.

Da die `'Wirbelkammer (Abt. 2 und 3) in der Mitte verengt ist, wird der Gasinhalt stärker nach außen verlagert, so daß der Umlauf in jeder Weise gefördert wird. Der frontale Abbrand des Gemisches wird durch die neue Formgebung der Brennkammer weitgehend verhindert. Der kreisend strömende Abbrand, wie ihn die Erfindung anstrebt, ist sowohl bei Zwei- als auch bei Viertaktmaschinen anwendbar. Das Auspuffventil 9 kann, wie dies aus der Abb. 3 ersichtlich ist, auch in die Wirbelkammer verlegt werden. Wird die Zündkerze 8 gemäß der Abb. 3 angeordnet, wird gleichfalls ein strömender und dabei schneller Abbrand des Gemisches erzielt.Since the vortex chamber (Dept. 2 and 3) is narrowed in the middle, the gas content is more strongly shifted to the outside, so that the circulation is promoted in every way will. The frontal burn-off of the mixture is due to the new shape of the combustion chamber largely prevented. The circling, flowing combustion, as the invention strives for, can be used with both two-stroke and four-stroke machines. The exhaust valve 9 can, as can be seen from Fig. 3, also relocated to the vortex chamber will. If the spark plug 8 is arranged as shown in FIG. 3, it also becomes a flowing one and achieved faster burning of the mixture.

Die Anordnung nach der Erfindung eignet sich besonders für schnell 1'amifende Motoren. Wird die Erfindung beim Einspritzbetrieb angewandt, wird die Einspritzdüse in oder in die Nähe des Halses der Wirbelkammer gesetzt. Die Zündstelle wird jedoch zweckmäßig im Abstand davon angeordnet.The arrangement according to the invention is particularly suitable for fast 1'amifende engines. If the invention is applied to the injection operation, the Injector placed in or near the neck of the vortex chamber. The ignition point however, it is expediently arranged at a distance therefrom.

Die zwischen Wirbelkammer und Zylinderkopf liegende Dichtung wird zweckentsprechend durch ein die Dichtung abdeckendes Mundstück überbrückt.The seal between the swirl chamber and the cylinder head is appropriately bridged by a mouthpiece covering the seal.
