Description

  

      Verbrennnngs-Sternmotor.       Die Erfindung bezieht sich auf eine Vier  taktbrennkraftmaschine mit neun in Stern  form angeordneten Zylindern, die durch eine  von den Abgasen der     Brennkraftmaschine    an  getriebene     Abgasturbogruppe    aufgeladen wer  den.  



  Die Erfindung besteht darin, dass die neun  Zylinder des Sternmotors in drei Gruppen zu  je drei Zylindern unterteilt sind, deren jede  an eine besondere     Auspuffsammelleitung    an  geschlossen ist, und zwar derart, dass zwi  schen je zwei an die gleiche Sammelleitung  angeschlossenen Zylindern sich zwei an die       Auspuffsammelleitungen    der andern Gruppen  angeschlossene Zylinder befinden.  



  In der Zeichnung ist ein Ausführungs  beispiel des Erfindungsgegenstandes darge  stellt. Es bezeichnen 1 bis 9 die Zylinder,  10 das Kurbelgehäuse des Sternmotors. Die  Kolben aller Zylinder arbeiten auf die gleiche,  zentral gelegene Kurbelwelle 11. Die Zylin  der sind in ihrer Zündreihenfolge numeriert;  der Zündabstand beträgt<B>800</B> und der Winkel    zwischen zwei benachbarten Zylindern ist 40  .  Die Auspuffstutzen der Zylinder 1 bis 9 sind  mit 1a bis 9a bezeichnet. Die Zylinder 4,  1, 7 sind unter Überspringen von je zwei  Zwischenzylindern an das     Auspuffsammelrohr     12 angeschlossen, die Zylinder 8, 5, 2 in  gleicher Weise an das     Auspuffsammelrohr    13  und die Zylinder 9, 6, 3 an das     Auspuff-          sammelrohr    14.

   Die drei Sammelrohre 12, 13  und 14 leiten die Abgase mittels der An  schlüsse 12a, 13a,     14a    in die     Abgasturbine     15, welche das Turbogebläse 16     antreibt.    Die  Druckleitung 17 des Turbogebläses ist in nicht  dargestellter Weise mit den Saugleitungen  der Zylinder 1 bis 9 verbunden. Der     Zünd-          abstand    der an die gleiche Sammelleitung an  geschlossenen Zylinder beträgt  3 X 80<B>0</B> = 240<B>0</B>,  so dass die Druckschwankungen in der Aus  puffleitung zur Unterstützung der Spülung  der Zylinder ausgenützt und Störungen der  Spülung durch den     Auspuff    anderer Zylinder  verhindert werden können.

        Es kann natürlich auch mehr als eine       Aufladegruppe    vorgesehen sein; zum Beispiel  kann jede der Sammelleitungen 12, 13, 14  an eine besondere     Aufladegruppe    angeschlos  sen sein.



      Combustion radial engine. The invention relates to a four-stroke internal combustion engine with nine cylinders arranged in a star shape, which are charged by an exhaust gas turbo group driven by the exhaust gases of the internal combustion engine.



  The invention consists in the fact that the nine cylinders of the radial engine are divided into three groups of three cylinders each, each of which is connected to a special exhaust manifold, in such a way that two cylinders each connected to the same manifold are connected to the Exhaust manifolds of the other groups connected cylinders are located.



  In the drawing, an embodiment example of the subject invention is Darge provides. 1 to 9 designate the cylinders, 10 the crankcase of the radial engine. The pistons of all cylinders work on the same, centrally located crankshaft 11. The cylinders are numbered in their firing order; the ignition interval is <B> 800 </B> and the angle between two adjacent cylinders is 40. The exhaust ports of the cylinders 1 to 9 are labeled 1a to 9a. The cylinders 4, 1, 7 are connected to the exhaust manifold 12 by skipping two intermediate cylinders, the cylinders 8, 5, 2 in the same way to the exhaust manifold 13 and the cylinders 9, 6, 3 to the exhaust manifold 14.

   The three manifolds 12, 13 and 14 conduct the exhaust gases by means of the connections 12a, 13a, 14a into the exhaust gas turbine 15, which drives the turbo blower 16. The pressure line 17 of the turbo blower is connected to the suction lines of the cylinders 1 to 9 in a manner not shown. The ignition interval of the cylinders connected to the same collecting line is 3 X 80 <B> 0 </B> = 240 <B> 0 </B>, so that the pressure fluctuations in the exhaust line are used to support the purging of the cylinders and interference with purging from the exhaust of other cylinders can be prevented.

        Of course, more than one charging group can also be provided; for example, each of the busses 12, 13, 14 may be tied to a particular charge group.
