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.
