Description

  

      Luftgekühlte        Brennkraftmaschine.       Die     Erfindung    betrifft eine     luftgekühlte          Brennkraftmaschine    mit in Reihen angeord  neten     Einzelzyl@uIern,    wobei die Kühlluft  quer zur     Zylinderreihe        ,strömt.     



  Bei     solchen        Maschinen        isst    es     bekannt,    die       Stösselführungen    der Ein- und     Auslassventile     und die Einspritzdüse in     Richtung    ,des Kühl  luftstromes     hintereinander    anzuordnen, um  das     Durchströmen    der     güblluft        möglichst     wenig zu behindern.

   Bei Einzelzylinderköp  fen bilden aber auch     ,die        ZylinderkopfecUrau-          ben        zwischen    je zwei     Einzelzylind'ern    Hin  dernisse für den     Kühlluftstrom.        Kommen     dazu nach grosse Ein- und     Auslasskanäle,    so  kann     unter    Umständen für die     KühEuft     kaum eine     Durahtrittsmö:glichkeit        vorhanden     sein.

   Zur Behebung     dieses        Übelstanäes,    musste  der     Zylinderabstand    und damit die Baulänge  und das     Gewicht    der     Maschine    vergrössert  werden.  



  Erfindungsgemäss soll die Kühlung bei  luftgekühlten     Brennkraftxna,sahi:nen    mit in  Reihen angeordneten     Einzelzylindern    mit  Einzelzylinderköpfen     dadlurch    verbessert sein,  dass die     Zylinderkopfsschrauben        zwischen    je  zwei benachbarten Zylindern in Richtung des       Kühlluftstromes    hintereinander angeordnet       sind.    Vorteilhaft     greifen    je zwei     benachbarte          Zydind'erköpfe    an den früher ebenen Stoss  flächen zahnartig ineinander. Dadurch wird  ein. kleiner     Zylinderabstand    ermöglicht.  



  Es sind nun     verschiedene        S,chranzbennvver-          teilungen    möglich, um diese angestrebte bes  sere     Kühlung    zu     erreichen.    Eine besonders    vorteilhafte     Verteilung    ist de, bei der die  Zylinderköpfe     trotz        Hintereinanderanomd-          nung    der     Schrauben    untereinander gleich  sind, bei der ferner die Summenkraft :

  der  Schraubendrücke mit der     Zylinderachse     zusammenfällt und bei der     endlich        eine    gün  stige Druckverteilung auf dem ganzen Um  fange jeder     Zylinderkopfdichtung        erreicht     wird.  



  Auf der Zeichnung ist ein     Ausführungs-          beiopiel    des     Erfindungsgegenstandes    in den       Fig.    1 und 2 im     Aufriss    und     Grundriss    dar  gestellt.     Fig.    3 zeigt eine andere Schrauben  verteilung.  



  In     Fig.    1 und 2 sind 1, 2 die     Butzen    au  .der einen und     S,    4     die    an des andern Stoss  <B>fläche</B> eines     Zylinderkopfes,    ferner 5-8 die       entsprechenden    Butzen der angrenzenden,     ge-          strichelt        angedeuteten    Zylinderköpfe.     d.        be-          -deutet    :

  die Achse der Zylinderreihe und B die  Richtung des     Kühlluftstromes.    Bei dieser  Anordnung der Schraubenbutzen greifen die  benachbarten Zylinderköpfe an den Stoss  flächen zahnartig ineinander. Die     Zylinder-          kopfschrauben        in    den Butzen 1, 2, 5, 6 und  3, 4, 7, 8 Ziegen in je einer     Reihe        hinter-          einander    und     \bieten    daher dem     Kühlluft-          sstrom    möglichst wenig     Widerstand.    Durch  ,die dargestellte     Verteilung    der Schrauben  wird aber auch erreicht,

   dass die Zylinder  köpfe untereinander gleich sind,     da-ss    die       Richtung    der     Summenkraft    der     Schrauben-          ,drucke    in die     Zylinderachse    fällt (weil die  die     Butzen    1, 3 und 2, 4 verbindenden Dia-           gonalen        durch    .die     Zylinderachse    ,gehen.) und       dass    eine gleichmässige     Druckverteilung    auf  dem ganzen     Umfante    jeder     Zylinderkopf-          dichtung    erreicht wird.  



  Mit der in     Fig.    3 dargestellten Verteilung  der     Zylinderkopfschrauben    wird die gleich  mässige     Druckverteilung    auf dem ganzen  Umfang jeder     Zylinderkopfdichtung    nur     un-          vallkommen    erreicht.



      Air-cooled internal combustion engine. The invention relates to an air-cooled internal combustion engine with single cylinders arranged in rows, the cooling air flowing transversely to the cylinder row.



  In such machines it is known to arrange the tappet guides of the inlet and outlet valves and the injection nozzle in the direction of the cooling air flow one behind the other in order to impede the flow of the güblluft as little as possible.

   In the case of individual cylinder heads, however, the cylinder head covers between each two individual cylinders also form obstacles to the flow of cooling air. If there are also large inlet and outlet ducts, there may be little opportunity for the cow to pass through.

   To remedy this nuisance, the cylinder spacing and thus the overall length and weight of the machine had to be increased.



  According to the invention, the cooling in air-cooled internal combustion engines with individual cylinders arranged in rows with individual cylinder heads should be improved by the fact that the cylinder head bolts are arranged one behind the other between two adjacent cylinders in the direction of the cooling air flow. Advantageously, two adjacent Zydind'erköpfe each engage in a tooth-like manner on the previously flat abutment surfaces. This becomes a. allows small cylinder spacing.



  Different peripheral distributions are now possible in order to achieve the desired better cooling. A particularly advantageous distribution is de, in which the cylinder heads are equal to one another despite the fact that the screws are positioned one behind the other, and in which the total force is also:

  the screw pressures coincide with the cylinder axis and finally a favorable pressure distribution over the whole order of each cylinder head gasket is achieved.



  In the drawing, an exemplary embodiment of the subject matter of the invention is shown in FIGS. 1 and 2 in elevation and plan. Fig. 3 shows another screw distribution.



  In FIGS. 1 and 2, 1, 2 are the slugs on one side and S, 4 are the slugs on the other of a cylinder head, furthermore 5-8 the corresponding slugs of the adjacent ones, indicated by dashed lines Cylinder heads. d. means:

  the axis of the cylinder bank and B the direction of the cooling air flow. With this arrangement of the screw lugs, the adjacent cylinder heads engage with one another like a tooth on the abutment surfaces. The cylinder head screws in the slugs 1, 2, 5, 6 and 3, 4, 7, 8 goats each in a row one behind the other and therefore offer as little resistance as possible to the flow of cooling air. The distribution of the screws shown here also achieves

   that the cylinder heads are identical to one another, that the direction of the total force of the screw pressures falls into the cylinder axis (because the diagonals connecting the slugs 1, 3 and 2, 4 go through the cylinder axis) and that an even pressure distribution over the entire circumference of each cylinder head gasket is achieved.



  With the distribution of the cylinder head bolts shown in FIG. 3, the uniform pressure distribution over the entire circumference of each cylinder head gasket is only achieved to an absolute degree.
