Description

  

  Dieselmotor.    Die Erfindung     des.        Hauptpatentes    betrifft  einen Dieselmotor, bei dem im     ebenen     Zylinderdeckel ausserhalb der Mitte und  schräg zur Achse eine Einspritzdüse an  geordnet und im Kolben ein kugeliger Ver  brennungsraum mit     einer    Öffnung vorge  sehen ist, die geringer ist als der grösste  Durchmesser des Verbrennungsraumes, wo  bei in der innern     Totpunktlage    der Abstand  der Spitze des Brennstoffkegels vom Zen  trum des     Verbrennungsraumes    mindestens  annähernd gleich dem Radius:

   des. letzteren  und die Achse des Brennstoffkegels nach  dem Mittelpunkt, des     Verbrennungsraumes          gerichtet    ist.  



  Bei den bisherigen Anordnungen ist die  Öffnung kreisrund und damit die     äusserste     Neigung der     Düsenachse    dadurch gegeben,  dass der senkrechte Abstand der     Düsenachse     von dem Punkt des Randes der Öffnung, der  in der gemeinsamen Ebene von Zylinder- und  Düsenachse in horizontaler Richtung am    weitesten entfernt von der Zylinderachse       liegt,    mindestens gleich dem Radius des  Düsensitzes ist. Bei stärkerer Neigung würde  ein Teil des Brennstoffstrahls den Rand und  die anschliessende Kolbenoberfläche treffen.  Eine     Vergrösserung    der Öffnung ist aber nicht       zulässig,    so dass die Neigung begrenzt war.

    Gemäss der zusätzlichen Erfindung wird       unterhalb    der Düse der Rand der Öffnung  auf ein kleines Stück ausgeschnitten, so dass  hier eine Aussparung entsteht. Hierdurch  wird ermöglicht, die Düse schräger einzu  setzen als bisher und bauliche     Vorteile    zu er  zielen, die darin     bestehen.,    die Einsatzstelle  der Düse am Zylinderkopf möglichst weit  von der     Zylindermitte,    wo die     Ventile    und  die Ventilantriebe sitzen, zu entfernen.  



  Wie sich ergeben hat, schadet diese Aus  sparung dem günstigen Ergebnis der Ver  brennung nicht. Bedenken, die einer .solchen  Verletzung der     Brennraumöffnung    entgegen  standen, haben sich als     gegenstandslos    er-           wiesen.    Es scheint sogar, dass der an dieser  Stelle sich zusammendrängende Luftstrom  günstig wirkt.  



  In der beiliegenden Zeichnung ist ein       Ausführungsbeispiel    des Erfindungsgegen  standes dargestellt.  



  Im Kolben     a    ist der kugelige Brennraum     l)     untergebracht, der mit dem sehr engen Kolben  spaltraum c durch die Öffnung d in Verbin  dung steht. Der Brennstoff wird durch die  schräg eingesetzte Düse e eingespritzt. Die  Neigung der Düsenachse f wäre an sich gege  ben durch die Bedingung. dass der in den  Raum b zu spritzende Strahl den Rand der  Öffnung d nicht treffen darf. Durch die  erfindungsgemässe Anordnung einer Aus  sparung     g    unterhalb der Düse kann diese  Neigung, wie die Zeichnung erkennen lässt,  wesentlich vergrössert werden.

   Wie schon  oben erwähnt, hat diese Aussparung keinen  ungünstigen Einfluss auf die vollkommene  Verbrennung und die bei derartigen Motoren       festgestellte,    besondere     vorteilhafte    Gesamt  wirkung, so dass durch die Anordnung dieser  Aussparung g ein vorzügliches Mittel an die  Hand gegeben ist, die Neigung der Düse so  weit zu vergrössern, dass die     Einsatzstelle       derselben am Zylinderkopf     ;so    weit von den  Ventilantrieben und dergleichen auf der       Oberseite        des    letzteren entfernt werden kann,  dass eine bequeme Anordnung und Bedienung  der     Düsenkörper    möglich ist.



  Diesel engine. The invention of the. Main patent relates to a diesel engine, in which in the flat cylinder cover outside the center and obliquely to the axis, an injection nozzle is arranged and in the piston a spherical combustion chamber with an opening is provided that is smaller than the largest diameter of the combustion chamber where In the case of the inner dead center position, the distance between the tip of the fuel cone and the center of the combustion chamber is at least approximately equal to the radius:

   The latter and the axis of the fuel cone is directed towards the center of the combustion chamber.



  In the previous arrangements, the opening is circular and thus the extreme inclination of the nozzle axis is given by the fact that the vertical distance of the nozzle axis from the point of the edge of the opening, which is furthest away from the horizontal direction in the common plane of the cylinder and nozzle axis The cylinder axis is at least equal to the radius of the nozzle seat. If the inclination was greater, part of the fuel jet would hit the edge and the adjacent piston surface. However, enlarging the opening is not permitted, so that the inclination was limited.

    According to the additional invention, the edge of the opening is cut out to a small piece below the nozzle, so that a recess is created here. This makes it possible to use the nozzle more obliquely than before and to achieve structural advantages, which consist in removing the point of use of the nozzle on the cylinder head as far as possible from the center of the cylinder, where the valves and valve drives are located.



  As it turned out, this recess does not harm the favorable result of the incineration. Concerns that opposed such a breach of the combustion chamber opening have proven to be irrelevant. It even seems that the air flow that is compressed at this point has a beneficial effect.



  In the accompanying drawing, an embodiment of the subject invention is shown.



  The spherical combustion chamber l) is housed in piston a and communicates with the very narrow piston gap c through opening d. The fuel is injected through the inclined nozzle e. The inclination of the nozzle axis f would be given by the condition. that the jet to be sprayed into space b must not hit the edge of opening d. By arranging a recess g below the nozzle according to the invention, this tendency, as the drawing shows, can be significantly increased.

   As already mentioned above, this recess has no unfavorable influence on the perfect combustion and the particularly advantageous overall effect found in such engines, so that the arrangement of this recess g provides an excellent means of tilting the nozzle so far to enlarge that the point of use of the same on the cylinder head; so far away from the valve drives and the like on the upper side of the latter that a comfortable arrangement and operation of the nozzle body is possible.
