Description

  

      Einspritz-Brennliraftmasebine    mit einer- in einem     gekiihlten    Zylinderdeckel  eingesetzten Vorkammer.    Die Erfindung betrifft     eineEinspritz-Brenn-          kraftmaschine    mit einer in einen gekühlten  Zylinderdeckel eingesetzten Vorkammer und  besteht darin, dass der     Vorkammerkörper    im  Zylinderdeckel durch eine bei dessen innerer  Wand angreifende, durch den Kühlraum und  die äussere Deckelwand hindurch nach     aussen     geführte Druckhülse, die im Deckelkühlraum  Aussparungen aufweist, an die innere Deckel  wand gepresst wird. Dadurch soll dem Vor  kammerkörper eine freie Ausdehnung in der       Einsetzrichtung    ermöglicht werden.

   Das Ganze  ist so, dass der     Vorkammerkörper    in jede  Lage gedreht werden kann.  



  Ein Ausführungsbeispiel des Erfindungs  gegenstandes ist auf der Zeichnung zur Dar  stellung gebracht.  



       Fig.    1 ist ein teilweiser Schnitt nach der  Linie     1-I    der     Fig.    2, und     Fig.    2 ein Schnitt  nach der Linie     II-II    der     Fig.    1.  



  a ist die innere, b die äussere Wand, c  der Kühlraum des nicht weiter gezeichneten  gekühlten Zylinderdeckels, d die Vorkammer    und e der gekühlte     Vorkammerkörper    einer       Vorkammer-Brennkraftmaschine,        deren.    Ver  brennungsraum mit f' bezeichnet ist. Der  Brennstoff wird durch die von der Nadel g  gesteuerte Düse     1a    in die Vorkammer einge  spritzt, dort zum Teil verbrannt und dann  von dem dabei sich ausdehnenden gasförmi  gen Kammerinhalt durch die     Öffnungen    i in  brennendem Zustand in den Verbrennungs  raum f geschleudert.

   Der     Vorkammerkörper     e wird durch Schrauben<I>k</I> mit     Muttern   <I>l</I> ver  mittelst einer mit einer Brille in versehenen  Druckbüchse n dichtend an die innere Wand a  des Zylinderdeckels     angepresst.    Die Druck  büchse n drückt auf einen Rand des Vor  kammerkörpers, der unmittelbar bei der innern  Wand a des Zylinderdeckels am Vorkammer  körper angeordnet ist derart, dass es dem im  Betrieb sich hoch erhitzenden Vorkammer  körper möglich ist, sich der Erhitzung ent  sprechend frei auszudehnen. In der Druck  büchse sind im Kühlraum des Zylinderdeckels  Fenster o ausgespart, so dass das Kühlwasser      des Zylinderdeckels ungehinderten Zutritt zu  dem     Vorkammerkörper    hat.

   Dieser kann nach  Lösen der     Muttern        l    in jede Lage gedreht  werden.



      Injection fuel cylinder with an antechamber inserted in a cooled cylinder cover. The invention relates to an injection internal combustion engine with an antechamber inserted into a cooled cylinder cover and consists in that the antechamber body in the cylinder cover is provided with recesses in the cover cooling chamber by a pressure sleeve that engages with its inner wall and passes through the cooling chamber and the outer cover wall has, is pressed against the inner cover wall. This is intended to allow the pre-chamber body to expand freely in the direction of insertion.

   The whole thing is such that the antechamber body can be rotated into any position.



  An embodiment of the subject invention is brought to the drawing for Dar position.



       1 is a partial section along line 1-I of FIG. 2, and FIG. 2 is a section along line II-II of FIG.



  a is the inner, b the outer wall, c the cooling chamber of the cooled cylinder cover (not shown), d the prechamber and e the cooled prechamber body of a prechamber internal combustion engine. Ver combustion chamber is denoted by f '. The fuel is injected into the prechamber through the nozzle 1a controlled by the needle g, where it is partly burned and then thrown into the combustion chamber f by the expanding gaseous chamber contents through the openings i in a burning state.

   The prechamber body e is pressed sealingly against the inner wall a of the cylinder cover by screws <I> k </I> with nuts <I> l </I> by means of a pressure sleeve n provided with a goggle. The pressure sleeve n presses on an edge of the pre-chamber body, which is arranged directly at the inner wall a of the cylinder cover on the pre-chamber body in such a way that it is possible for the pre-chamber body, which heats up during operation, to expand freely according to the heating. In the pressure sleeve windows o are recessed in the cooling space of the cylinder cover so that the cooling water of the cylinder cover has unimpeded access to the antechamber body.

   This can be turned into any position after loosening the nuts l.
