Description

  

  Selbstzündende     Verbrennungskraftmaschine.       Gegenstand der Erfindung ist eine selbst  zündende     Verbrennungskraftmaschine,    wel  ehe sieh dadurch auszeichnet, dass ein Teil  der den Kompressionsraum des Zylinders  bildenden Wandung zur Veränderung des  Kompressionsraumes und des Kompressions  druckes verstellbar ist. Bei einer derart ein  berichteten Maschine lässt sich demnach zum  Beispiel beim Anlassen der Kompressions  raum verringern und somit der Kompressions  druck entsprechend erhöhen, so dass man  selbst bei Verwendung von gröbsten Roh  ölen unter Verzicht jedweder besonderen  Zündvorrichtung vom kalten Zustande aus  eine Selbstzündung herbeiführen kann. Auch  im Betriebe kann der Kompressionsraum  derart eingestellt werden, dass Frühzündun  gen infolge zu starker Erwärmung vermieden  werden.

    



  Der bewegliche     Wandungsteil    wird zweck  mässig durch einen in den Zylinder eingesetz  ten Gegenkolben gebildet, der mittelst einer  in einem Zylinderdeckel geführten Schrau  benspindel im Zylinder     achsial    verstellbar  ist. .  



  Die beiliegende Zeichnung zeigt ein Aus  führungsbeispiel des Erfindungsgegenstan-    des, wovon     Fig.    1 einen Vertikalschnitt,       Fig.    2 einen dazu senkrechten Vertikalteil  schnitt und     Fig.    3 einen Horizontalschnitt  nach der Linie     a-b    in     Fig.    1 darstellt.    Im Arbeitszylinder 1 des     gezeichneten     stehenden Explosionsmotors ist der Arbeits  kolben 2 verschiebbar.

   Der Zylinder 1 weist  im untern Teil zwei vertikale, im Kurbel  gehäuse 15 mündende Längskanäle 4 auf,  die von zwei     Ausnehmungen    ä am Kolben 2  in seiner untern     Totpunktlage    freigelegt wer  den. Überdies besitzt der Zylinder 1 zwei  Schlitze 5 zur Zufuhr von Brennstoffluft  gemisch, das durch Stutzen 6 den Schlitzen 5  zuströmt. Die Verbrennungsgase werden  durch die Schlitze 7 und die Stutzen 8 des  Zylinders abgeführt. Im Oberteil des Zylin  ders 1 ist ein Gegenkolben 10 untergebracht,  der mittelst einer im Zylinderdeckel 9 ge  führten Schraubenspindel 11 im Zylinder 1       achsial    verstellbar ist, beim normalen Be  triebe aber unbeweglich ist.  



  Zum Anlassen wird der Gegenkolben 10       mittelst    der Spindel 11 im Zylinder 1     in     seine tiefste Stellung verschoben, um den Kom  pressionsraum im Zylinder zu verringern.      Für den Betrieb wird der Gegenkolben 10  wieder in normale Stellung     zurückgeführt.     



  Beim Arbeiten komprimiert der hoch  gehende Kolben 2 die über ihm befindliche  Ladung bis zur Selbstzündung, während er  gleichzeitig unter ihm ein Vakuum schafft,  zufolge dessen schliesslich Brennstoffluft  gemisch durch die Schlitze 5 in den Zylinder  raum unter dem Kolben und in das Kurbel  gehäuse 15 eingesaugt wird.

   Beim darauf  folgenden Niedergehen des Kolbens 2, das  durch den     Druck    der     Verbrennungsgase    be  wirkt wird, kommen dieselben schliesslich  durch die Schlitze 7 zum Auspuff, während  die frische Ladung durch die Zylinderkanäle  4 und die     Kolbenausnehmungen    3 in zwei  getrennten kompakten Strömen, die mit den  abziehenden     Verbrenungsgasen    keine Mi  schung eingehen, in den     Zylinder    eingeblasen  wird, um nachher komprimiert zu werden.  Im normalen     Betrieb    bleibt der Gegenkolben  10 unbeweglich.

   Soll aus irgend einem Grund  der Kompressionsdruck im Zylinder während  des Betriebes geändert werden, so genügt es,  den Gegenkolben 10 im Zylinder mittelst der  Schraubenspindel 11 höher oder tiefer zu  stellen.



  Self-igniting internal combustion engine. The invention relates to a self-igniting internal combustion engine, which is characterized in that part of the wall forming the compression chamber of the cylinder can be adjusted to change the compression chamber and the compression pressure. With such a reported machine, for example, the compression space can be reduced when starting and thus the compression pressure increased accordingly, so that even when using the coarsest crude oils, self-ignition can be caused from a cold state without any special ignition device. The compression chamber can also be set in operation in such a way that premature ignition due to excessive heating is avoided.

    



  The movable wall part is expediently formed by an opposing piston inserted into the cylinder, which is axially adjustable in the cylinder by means of a screw guided in a cylinder cover. .



  The accompanying drawing shows an exemplary embodiment of the subject matter of the invention, of which FIG. 1 is a vertical section, FIG. 2 is a vertical section perpendicular thereto and FIG. 3 is a horizontal section along the line a-b in FIG. In the working cylinder 1 of the drawn standing explosion engine, the working piston 2 is displaceable.

   The cylinder 1 has in the lower part two vertical, in the crank housing 15 opening longitudinal channels 4, which exposed by two recesses ä on the piston 2 in its bottom dead center who the. In addition, the cylinder 1 has two slots 5 for the supply of fuel-air mixture, which flows through the nozzle 6 to the slots 5. The combustion gases are discharged through the slots 7 and the nozzle 8 of the cylinder. In the upper part of the cylinder 1 a counter piston 10 is housed, which is axially adjustable by means of a ge in the cylinder cover 9 guided screw spindle 11 in the cylinder 1, but is immobile in normal loading operations.



  To start the opposed piston 10 is moved by means of the spindle 11 in the cylinder 1 to its lowest position in order to reduce the compression space in the cylinder. For operation, the opposing piston 10 is returned to its normal position.



  When working, the rising piston 2 compresses the charge above it until it spontaneously ignites, while at the same time it creates a vacuum under it, according to which the fuel-air mixture is finally sucked in through the slots 5 in the cylinder space under the piston and in the crankcase 15 .

   When the piston 2 subsequently descends, which is acted upon by the pressure of the combustion gases, the same finally come through the slots 7 to the exhaust, while the fresh charge flows through the cylinder ducts 4 and the piston recesses 3 in two separate compact flows, which with the withdrawing Combustion gases do not enter into a mixture, is blown into the cylinder to be compressed afterwards. In normal operation, the opposing piston 10 remains immobile.

   If, for whatever reason, the compression pressure in the cylinder is to be changed during operation, it is sufficient to set the opposing piston 10 in the cylinder higher or lower by means of the screw spindle 11.
