Description

  

      Yiertakt-Egplosionsla        aftmaschine.       Vorliegende Erfindung betrifft eine     Vier-          taktegplosionskraftmaschine,    bei welcher  dem Arbeitszylinder ausser der vom Kolben  angesaugten, normalen Ladung noch eine  vom Kolben im Kurbelgehäuse verdichtete       Gemischnachladung    zugeführt wird. Die da  durch erzielte Überladung des Arbeitszylin  ders hat eine wesentliche Leistungssteigerung  des Motors zur Folge.  



  Als Ausführungsbeispiel des Erfindungs  gegenstandes ist auf beiliegender Zeichnung  ein Vergasermotor im Schnitt dargestellt.  



  Der Arbeitsgang ist folgender:  Durch die vom Vergaser H abzweigende  Saugleitung     H2    wird beim     Verdichtungs-    und       Auspuffhub    des Kolbens B, von der Unter  kante des Kolbens gesteuert, Brennstoffluft  gemisch in das Kurbelgehäuse C gesaugt.

    Bei dem darauffolgenden Saughub des Kol  bens B strömt einerseits durch den Kanal     Hl     und das Ansaugventil     G    Gemisch in den  Zylinder A, anderseits wird das vorher in  das Kurbelgehäuse gesaugte     Nachladegemisch       vom Kolben zusammengedrängt und am Ende  des Saughubes, nachdem das Saugventil ge  schlossen worden, durch ein Kolbenfenster  und den     Überströmkanal    F, von der Kante     E     am rotierenden Drehschieber D gesteuert,  durch die     Öffnung    J in den Arbeitszylinder  gepresst.

   Hierauf folgt der     Verdichtungs-,     dann der     Arbeits-    und     darauf    der     Auspuff-          hub.    Die     Öffnung    J ist während des     Arbeits-          und    Auspuffhubes durch den Drehschieber D  vom Kanal F abgeschlossen; sie wird auch  während des Kompressionstaktes durch den  Drehschieber D vom Kanal F abgeschlossen.  In der Praxis hat sich jedoch bei gegen  läufiger Drehung des Drehschiebers (entgegen  dem Sinne des Uhrzeigers) gezeigt, dass der  Drehschieber, unbeschadet der Auswirkung,  auch eine     kurze    Zeit nach Beginn des Rück  laufes des Kolbens vom untern Totpunkt  schliessen darf.

    



  Zu bemerken ist noch, dass bei rück  läufiger Bewegung des Drehschiebers (ent  gegengesetzt dem Sinne des Uhrzeigers) nicht  die Kante     E    des Drehschiebers die Nach-           ladung    steuert, sondern die derselben gegen  überliegende gante des Drehschiebers.  



  Die nicht gezeichneten Betätigungsorgane  für die im Zylinderkopf sitzenden     Ansaug-          und    Auspuffventile, von welchen das letztere  in der Zeichnung nicht sichtbar ist,     sind    am  Drehschieber angebracht..



      Yier-stroke egplosion-run machine. The present invention relates to a four-stroke explosion engine in which, in addition to the normal charge sucked in by the piston, a mixture recharge compressed by the piston in the crankcase is fed to the working cylinder. The achieved by overloading the Arbeitszylin countries has a significant increase in engine performance.



  As an embodiment of the subject invention, a carburetor engine is shown in section on the accompanying drawing.



  The process is as follows: Through the suction line H2 branching off from the carburetor H, a mixture of fuel and air is sucked into the crankcase C during the compression and exhaust stroke of the piston B, controlled by the lower edge of the piston.

    During the subsequent suction stroke of the piston B, on the one hand, the mixture flows through the channel Hl and the suction valve G into the cylinder A; on the other hand, the recharge mixture previously sucked into the crankcase is compressed by the piston and at the end of the suction stroke, after the suction valve has been closed a piston window and the overflow channel F, controlled by the edge E on the rotating rotary valve D, pressed through the opening J into the working cylinder.

   This is followed by the compression stroke, then the working stroke and then the exhaust stroke. The opening J is closed during the working and exhaust stroke by the rotary valve D from the channel F; it is also closed off from channel F by rotary valve D during the compression stroke. In practice, however, when the rotary valve is turned in the opposite direction (counterclockwise) it has been shown that the rotary valve, regardless of the effect, may close even a short time after the piston begins to return from bottom dead center.

    



  It should also be noted that when the rotary valve moves backwards (opposite to the clockwise direction), it is not the edge E of the rotary valve that controls the reloading, but the opposite edge of the rotary valve.



  The actuators, not shown, for the intake and exhaust valves located in the cylinder head, of which the latter is not visible in the drawing, are attached to the rotary valve.
