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.
