Description

  

      Doppeltwirkende        Verbrennungskraftmasehine    mit mittelst Abgasturbine  angetriebener     Aufladepumpe.       Die Erfindung bezieht sich auf doppelt  wirkende     Verbrennungskraftmaschinen    mit  mittelst Abgasturbine angetriebener Auflade  pumpe. Gemäss der Erfindung puffen nur  Zylinderseiten in die gleiche Abgasturbine  beziehungsweise     Abgasturbinenkammer    aus,  deren Verbrennungen mindestens 1440 Kur  belwinkel     auseinanderliegen    und die Ladung  wird diesen Zylinderseiten durch miteinander  verbundene Leitungen zugeführt.

   So zum  Beispiel können bei     Viertaktmaschinen    mit  vier Zylindern zwei Turbinen beziehungsweise  zwei Turbinenkammern vorhanden sein und  je vier Zylinderseiten in die gleiche Turbine  beziehungsweise Turbinenkammer     auspuffen.     Bei     Sechszylinder-Viertaktmaschinen    können  vier Turbinen beziehungsweise vier Turbinen  kammern vorhanden sein, in welche je drei  Zylinderseiten     auspuffen;

      bei     Achtzylinder-          Viertaktmaschinen    je zwei Turbinen mit je  zwei Kammern pro Turbine, in welche je vier  Zylinderseiten     auspuffen,    und bei Zwölf  zylinder-Viertaktmotoren zwei Turbinen mit    je vier Kammern, in welche je drei Zylinder  seiten     auspuffen    usw.  



  Die     Fig.    1, 2 und 3 der beiliegenden  Zeichnung     betreffen    ein Ausführungsbeispiel  des Erfindungsgegenstandes.  



       Fig.    1 zeigt eine vertikale,     doppeltwirkende          Vierzylinder-Viertaktmaschine    mit den Zy  lindern 1, 2, 3 und 4. 5 und 6 sind zwei  Abgasturbinen, 7 und 8 sind von diesen  Abgasturbinen angetriebene Gebläse.  



  Die Kurbelanordnung dieser Maschine ist  aus     Fig.2    ersichtlich. Die Kurbeln liegen  alle in einer Ebene, so dass die Verbrennung  nach je<B>1801</B> in zwei Zylinderseiten gleich  zeitig stattfindet. Die     obern    und untern Seiten  der Zylinder 1 und 2 puffen durch die  Leitung 9 in die Abgasturbine 5 und die  obern und untern Seiten der Zylinder 3 und  4 durch die Leitung 10 in die Abgasturbine  6 aus. Das Gebläse 7 fördert durch die  Leitungen 11 und 12 in beide Seiten der  Zylinder 1 und 2 'und das Gebläse 8 durch  die Leitungen 13 und 14 in beide Seiten      der Zylinder 3 und 4. Die Leitungen 11 und  13, beziehungsweise 12 und 14 können, wie  punktiert angedeutet, auch miteinander ver  bunden sein, so dass vor allen     Einlassventilen     der gleiche Druck herrscht. .  



  In     Fig.    3 ist der Druckverlauf vor einer  der beiden Turbinen 5 beziehungsweise 6  durch die Linie     pt    dargestellt.     p"    ist der  Atmosphärendruck; pl der     Aufladedruck.     Dieser ist annähernd konstant, während der  Abgasdruck     pt    vor der Turbine verhältnis  mässig stark schwankt, indem das Volumen  der Abgasleitung zwischen der     Verbrennungs-          kraftmaschine    und der Turbine verhältnis  mässig klein angenommen wird.

   Die Schwan  kung des Druckes     pt    ist bald grösser bald  kleiner, und zwar rühren die höheren Drücke  von den     obern    Zylinderseiten und die niedern  Drücke von den untern Zylinderseiten her.       Man    erkennt sofort, dass bei Maschinen, bei  welchen die Zylinder mit     Aufladeluft    gespült  werden, es möglich wird, in den untern       Zylinderseiten    mit dem niedern Druck eine  längere und ausgeprägtere Spülperiode     82.    zu  erzielen, als wie diejenige<B>81</B> in den obern  Zylinderseiten.  



  Natürlich könnte auch der Auspuffdruck  in der Abgasleitung der obern Zylinderseiten  kleiner gehalten werden als in der untern,  zum Beispiel durch geringere Brennstoffzu  fuhr, so dass die obern Zylinderseiten besser  gespült würden als die untern.



      Double-acting internal combustion engine with a supercharging pump driven by an exhaust gas turbine. The invention relates to double-acting internal combustion engines with a charging pump driven by means of an exhaust gas turbine. According to the invention, only cylinder sides puff out into the same exhaust gas turbine or exhaust gas turbine chamber whose burns are at least 1440 cures apart and the charge is fed to these cylinder sides through interconnected lines.

   For example, four-stroke engines with four cylinders can have two turbines or two turbine chambers and each exhaust four cylinder sides into the same turbine or turbine chamber. In the case of six-cylinder four-stroke engines, four turbines or four turbine chambers can be present, into each of which three cylinder sides exhaust;

      in eight-cylinder four-stroke engines two turbines with two chambers per turbine, into which four cylinder sides each exhaust, and in twelve-cylinder four-stroke engines two turbines with four chambers each, into which three cylinder sides exhaust, etc.



  1, 2 and 3 of the accompanying drawings relate to an embodiment of the subject invention.



       Fig. 1 shows a vertical, double-acting four-cylinder four-stroke engine with the Zy alleviate 1, 2, 3 and 4. 5 and 6 are two exhaust gas turbines, 7 and 8 are fans driven by these exhaust gas turbines.



  The crank arrangement of this machine can be seen from Fig.2. The cranks are all in one plane, so that after <B> 1801 </B> the combustion takes place simultaneously in two cylinder sides. The upper and lower sides of the cylinders 1 and 2 puff through the line 9 into the exhaust gas turbine 5 and the upper and lower sides of the cylinders 3 and 4 through the line 10 into the exhaust gas turbine 6. The fan 7 feeds through the lines 11 and 12 into both sides of the cylinders 1 and 2 'and the fan 8 through the lines 13 and 14 into both sides of the cylinders 3 and 4. The lines 11 and 13, or 12 and 14 can, as indicated by dotted lines, also be connected to one another so that the same pressure prevails in front of all inlet valves. .



  In Fig. 3, the pressure curve in front of one of the two turbines 5 or 6 is shown by the line pt. p "is the atmospheric pressure; pl is the boost pressure. This is approximately constant, while the exhaust gas pressure pt in front of the turbine fluctuates relatively strongly because the volume of the exhaust pipe between the internal combustion engine and the turbine is assumed to be relatively small.

   The fluctuation of the pressure pt is sometimes greater sometimes smaller, namely the higher pressures originate from the upper cylinder sides and the lower pressures from the lower cylinder sides. It can be seen immediately that in machines in which the cylinders are purged with supercharging air, it is possible to achieve a longer and more pronounced purge period 82 in the lower cylinder sides with the low pressure than that of 81 in the upper cylinder sides.



  Of course, the exhaust pressure in the exhaust line of the upper cylinder sides could also be kept lower than in the lower one, for example by lower fuel supply, so that the upper cylinder sides would be better flushed than the lower one.
