Description

Zerstäuberdüse für den Hilfsbrennstoff bei Einspritzverbrennungskraftmaschinen. Die Erfindung richtet sich auf die weitere Ausbildung des Verfahrens des Patents 33976o bei dem außer dem Brennstoff für die Zündkammerarbeit von Einspritzverbrennungskraftmaschinen mit Selbstzündung eine besondere kleine Menge von Hilfsbrennstoff unmittelbar in den heißen Kern der verdichteten Zylinderluft gespritzt wird.Atomizer nozzle for the auxiliary fuel in injection internal combustion engines. The invention is directed to the further development of the method of the patent 33976o in addition to the fuel for the ignition chamber work of internal combustion engines with auto-ignition a particularly small amount of auxiliary fuel immediately in the hot core of the compressed cylinder air is injected.

Es ist nun von besonderer Wichtigkeit, daß der eingespritzte Hilfstropfen möglichst vollkommen zerstäubt wird, und zwar mit kurzer, buschiger Flammenbildung, so daß die entstehende Stichflamme unterhalb des Schußkanals zur Ruhe kommt und den aus dem Schußkanal austretenden Strahl nicht hindert in seiner Entfaltung. Zur Lösung dieser Aufgabe_ macht die Erfindung von der an sich beannten Ausrüstung der Düse mit zwei im Winkel zueinander stehenden Bohrungen Gebrauch, wobei die Eigenart darin besteht, daß die Bohrungen, ihr Winkel und der Abstand der Düse von der Mündung des Schußkanals derart gewählt werden, daß die Stichflamme des Hilfsbrennstoffes unterhalb des Schußkanals der Zündkammer zur Ruhe kommen läßt. Der genauen Herstellung der Bohrungen, auf die es hierbei ankommt, dient ein besonderes Verfahren.It is now of particular importance that the injected auxiliary drop is atomized as completely as possible, with a short, bushy flame formation, so that the resulting jet flame comes to rest below the firing channel and does not prevent the jet emerging from the firing channel from developing. To the This problem is solved by the invention of the equipment of the Nozzle with two holes at an angle to each other use, whereby the peculiarity is that the holes, their angle and the distance of the nozzle from the mouth the firing channel can be chosen so that the jet flame of the auxiliary fuel can come to rest below the firing channel of the ignition chamber. The exact manufacture A special procedure is used for the drilling, which is important here.

Auf der Zeichnung ist die Erfindung durch einen Schnitt in starker Vergrößerung dargestellt.In the drawing, the invention is shown in greater detail by a section Shown enlarged.

Die Düse für das Einspritzen des Hilfsbrennstoffes in den Zylinder besitzt einen Hauptkanal I und dieser Kanal endigt unten in zwei kleineren Kanälen II und III, - deren Achsen sich an bestimmter Stelle frei im Raume schneiden sollen. Um dies sicher zu erreichen, wird bei der Herstellung der Düsenschaft zunächst mit einer rings umlaufenden Verdickung hergestellt, die punktiert eingezeichnet ist. Die beiden Kanäle II und III werden von einem gemeinsamen Körnerschlag IV vom Umfang der Verdickung aus in einem bestimmten Winkel zueinander nach dem Hauptkanal I hin. gebohrt, und dann entfernt man den äußeren Teil der Verdickung bis zu der in der Zeichnung dargestellten Fläche. Die Strahlen, die nunmehr frei im Raum zusammenprallen, geben die gewünschte kurze, buschige Stichflamme, die unterhalb des Schußkanals zur Ruhe kommt.The nozzle for injecting the auxiliary fuel into the cylinder has a main channel I and this channel ends at the bottom in two smaller channels II and III, - whose axes should intersect freely in space at a certain point. In order to achieve this reliably, the nozzle shaft is initially produced with a circumferential thickening produced, which is drawn in dotted. The two channels II and III are covered by a common center punch IV the thickening from at a certain angle to each other towards the main channel I. drilled, and then you remove the outer part of the thickening up to the inside Area shown in the drawing. The rays that now freely collide in space, give the desired short, bushy jet flame, the one below the firing channel comes to rest.

Selbstverständlich können auch mehrere solcher Doppelkanäle am Düsenende angeordnet werden.Of course, several such double channels can also be used at the nozzle end to be ordered.
