Description

  

      Glühkopfmotor    mit durch einen engen Hals mit dem Zylinder verbundener       Zündkammer.            Verbrennuncskraftmaschinen    ergeben un  ter sonst gleichen Verhältnissen bei höherer  Verdichtung eine grössere Leistung und ge  ringeren Brennstoffverbrauch. Die Verdich  tung     lässt    sieh     steigera,    wenn man dem Ver  dichtungsraum, eine kleinere innere Wand  fläche gibt.

   Dies beruht darauf,     dass        #die    Wan  dung des     Verdiehtungsraumes    trotz der äu  sseren Wasserkühlung eine ziemlich     erlieb-          liche    Wärmemenge aufspeichert und an die  sie berührende Schicht des brennbaren     Brenn-          stoffgas-Luftgemisches    abgibt.

   Je grösser  nun     #die        Innenfläche    der Wandung des     Ver-          diclitungsraumes    ist, desto mehr Wärme wird  auf das brennbare Gemisch     übertraggen.    Bei  örtlich stark erhitztem     Gasgeinisch    kann aber  die Kompression nicht so hoch getrieben wer  den, wie bei weniger stark erhitztem Gemisch,  weil im ersteren Falle die Selbstentzündung  <I>des Gemisches</I> bereits bei niedrigerem Druck       ZD     eintritt.

         CT1ü711kopfmotoren    sind zweckmässig der  art eingerichtet,     dass    ihre Zündkammer mit  dem Zylinder durch einen engen Hals ver-         bunden    ist. Dadurch erhält der Verdichtungs  raum naturgemäss eine sehr grosse innere       WandflIche.    Damit die Erwärmung des  brennbaren Gemisches durch die berührende  Wand klein ist, besteht gemäss der Erfindung  der gekühlte Teil der Wandung der     Zünd-          kammer"desVerbindungslialses        undder    übrige       Verdielitungsraum    aus einem gut wärme  leitenden Material, das ein höheres Leitungs  vermögen besitzt als das bisher verwandte       Gusseisen,

      beispielsweise Aluminium. Da  durch wird erreicht,     dass    mehr Wärme von  der     Innenfläche    des     Verdielitungsraumes    ab  geleitet wird und damit das Gasgemisch in  der Nähe der     Wandungsfläche    kälter bleibt,  so     #class    die Kompression höher getrieben wer  den kann, ohne     dass        Selbstentzünduno,    eintritt.  



  Die Zeichnung zeigt ein     Ausführunggs-          beispiel    des Erfindungsgegenstandes. Die  Zündkammer a ist oben neben dem     Z3,linder     <B>b</B> angeordnet und mit -diesem durch einen en  gen Hals     c    verbunden. Die Glühplatte<B>d</B> ist  von unten in die Zündkammer eingesetzt.

   Die       W-andung    e der Zündkammer einschliesslich      des Halses, die von aussen unter     clem        Einfluss     des Kühlmittels steht, ist ebenso wie die des       übrio#en        Verdielitungsraumes    aus einem     g1,111          21        tD          %vä.rmele#.tendeii    Mittel, z. B. Aluminium,  hergestellt.



      Hot-head engine with an ignition chamber connected to the cylinder by a narrow neck. Combustion engines, under otherwise the same conditions, produce greater power and lower fuel consumption with higher compression. The compression can be seen to increase if the compression space is given a smaller inner wall area.

   This is based on the fact that # the wall of the compression space stores a fairly acceptable amount of heat despite the external water cooling and transfers it to the layer of the combustible fuel gas-air mixture in contact with it.

   The larger the inner surface of the wall of the compression space is, the more heat is transferred to the combustible mixture. In the case of locally strongly heated gas mixture, however, the compression cannot be driven as high as in the case of a less strongly heated mixture, because in the former case self-ignition <I> of the mixture </I> already occurs at a lower pressure ZD.

         CT1ü711 head motors are expediently set up in such a way that their ignition chamber is connected to the cylinder by a narrow neck. This naturally gives the compression space a very large internal wall area. According to the invention, the cooled part of the wall of the ignition chamber "desVerbindungsliales" and the rest of the conduit space are made of a material that conducts heat well, which has a higher conductivity than the cast iron used up to now,

      for example aluminum. This ensures that more heat is conducted away from the inner surface of the distribution space and thus the gas mixture in the vicinity of the wall surface remains colder, so #class the compression can be driven higher without spontaneous ignition occurring.



  The drawing shows an exemplary embodiment of the subject matter of the invention. The ignition chamber a is arranged at the top next to the Z3, linder <B> b </B> and connected to it by a narrow neck c. The glow plate <B> d </B> is inserted into the ignition chamber from below.

   The wall of the ignition chamber including the neck, which is under the influence of the coolant from the outside, is just like that of the rest of the conduit space from a g1,111 21 tD% vä.rmele # .tendeii means, e.g. B. aluminum.
