Description
Einspritz-Br ennkraftmaschine. Es sind bereits Einspritz-Brennkraftmaschi- nen bekannt, bei denen der Brennstoff durch mehrere Düsen in den Verbrennungsraum eingespritzt wird. Bei diesen Maschinen sind die Zuleitungen zu den einzelnen Düsen in offener Verbindung mit einem Brennstoff verteiler, der seinerseits durch ein Brennstoff zufuhrorgan an eine gemeinsame Druck leitung der Brennstoffpumpe angeschlossen ist.
Es hat sich gezeigt, dass die Brennstoff säulen der durch den Verteiler ständig mit einander verbundenen Düsenzuleitungen bei solchen Maschinen derart ins Pendeln geraten können, dass sich der Brennstoff sehr ungleich auf die verschiedenen Düsen verteilt und eine Störung des Einspritzvorganges die Folge ist.
Mit der vorliegenden Erfindung wird die Beseitigung dieses Übelstandes bezweckt. Die Erfindung besteht darin, dass die Düsen des Verbrennungsraumes an je eine in die Sitzfläche eines gemeinsamen Brennstoffver- teilventils einmündende Leitung angeschlossen sind. Dadurch wird ein Pendeln des Brenn stoffes verhindert und damit eine vollständig gleichmässige Verteilung des Brennstoffes auf die verschiedenen Düsen sowie einwand freie Einspritzung und Verbrennung des Brennstoffes erzielt.
Ein Ausführungsbeispiel des Erfindungs gegenstandes ist auf der Zeichnung zur Dar stellung gebracht.
a ist der Arbeitszylinder,<I>b</I> der Kolben und c der Verbrennungsraum einer Einspritz- Brennkraftmaschine, bei welcher der durch die Leitung d von einer nicht gezeichneten Pumpe gelieferte Brennstoff über ein zentrales Brennstoffverteilventil e, das vom Brennstoff selbst angehoben wird, durch mehrere gleich mässig verteilte Düsen f - die Zeichnung zeigt nur zwei - in den Verbrennungsraum eingespritzt wird.
Die einzelnen Düsenzulei tungen sind je an eine besondere, im Sitz des Ventils e angeordnete Öffnung g ange schlossen, derart, dass bei geschlossenem Ven til jegliche Verbindung zwischen den einzel nen Zuleitungen unterbunden und ein Pen deln der darin sich befiindenden Brennstoff säulen unmöglich ist.
Injection internal combustion engine. Injection internal combustion engines are already known in which the fuel is injected into the combustion chamber through a plurality of nozzles. In these machines, the feed lines to the individual nozzles are in open connection with a fuel distributor, which in turn is connected to a common pressure line of the fuel pump through a fuel supply element.
It has been shown that the fuel columns of the nozzle feed lines that are constantly connected to one another by the distributor can start to oscillate in such machines that the fuel is distributed very unevenly to the different nozzles and the result is a disruption of the injection process.
The present invention aims to remedy this drawback. The invention consists in that the nozzles of the combustion chamber are each connected to a line opening into the seat of a common fuel distribution valve. This prevents the fuel from oscillating and thus achieves a completely even distribution of the fuel to the various nozzles as well as perfect injection and combustion of the fuel.
An embodiment of the subject invention is brought to the drawing for Dar position.
a is the working cylinder, <I> b </I> the piston and c the combustion chamber of an injection internal combustion engine, in which the fuel delivered through line d by a pump (not shown) is via a central fuel distribution valve e which is raised by the fuel itself , through several evenly distributed nozzles f - the drawing shows only two - is injected into the combustion chamber.
The individual nozzle feed lines are each connected to a special opening g located in the seat of valve e, in such a way that when the valve is closed, any connection between the individual feed lines is prevented and the fuel columns located therein cannot swing.
