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.
