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.
