Description
Abgasleitung an mehrzylindrigen *Verbrennungsmotoren mit Abgasturbine. Die Erfindung bezieht sich auf die Ab gasleitung an mehrzylindrigen Verbrennungs motoren mit Abgasturbine. Ihr gemäss werden die Abgase von den Verbrennungszylindern durch Auspuffrohre auf mindestens eine Länge von zwei Zylinderdurchmessern getrennt in we nigstens eine Sammelleitung geführt.
Speziell bei raschlaufenden Motoren kann im Sammel- rohr eine Zwischenwand bis zur Einmündung des Rohres in die Turbine angeordnet sein; und ein Teil der Verbrennungszylinder kann auf die eine und die übrigen auf die andere Seite der Zwischenwand in das Sammelrohr aus- puffen. Die Auspuffrohre besitzen einer. ver hältnismässig kleinen Querschnitt, um in den selben eine entsprechend grössere Geschwin digkeit zu erzielen. Zweckmässig münden in eine Sammelleitung nur die Auspuffrohre von Zylindern, deren Auspuffe sich in mindestens 1$0 Kurbelwinkel folgen.
Mit dem Erfindungsgegenstand erzielt man den Vorteil, dass die Auspuffvorgänge in den Zylindern, die an die gleiche Sammel- leitung angeschlossen sind, einander nicht so leicht stören und die beim Beginn des Aus puffhubes freiwerdende kinetische Energie zum grossen Teil direkt auf die Turbine über tragen wird. Auch können störende Druck schwankungen in den Abgasleitungen leicht vermieden werden, da die Zahl der Auspuffe in einzelnen Leitungsteilen kleiner ist.
Auf den beiliegenden Zeichnungen ist ein Ausführungsbeispiel des Erfindungsgegen standes an einem achtzylindrigen Viertakt motor dargestellt. Fig. 1 ist der Aufriss, Fig. 2 der Grundriss der Verbrennungskraftmaschine; die Fig. 3 bis 6 zeigen die Anschlüsse der Auspuffleitungen der verschiedenen Zylinder an die Sammelleitungen; Fig.7 zeigt die Kurbelstellung. Die Zündfolge der Zylinder ist in Fig. 1 mit römischen Ziffern angegeben.
In den Figuren ist mit 1 die achtzylin drige Verbrennungskraftmaschine bezeichnet, mit 3 bis 10 die Zylinder und mit 2 ein Generator, der durch die Verbrennungskraft maschine angetrieben wird. 12 ist die Ab- gasturbine, die das Aufladegebläse 26 an treibt. Dieses fördert in die Aufladeleitung 24. Die Auspuffrohre 15 bis 22 der Verbren nungszylinder münden derart in die Sammel- rohre 13 -resp. 14, dass beim Überströmen ein möglichst kleiner Geschwindigkeitsver lust entsteht.
In den Sammelleitungen 13 und 14 sind Zwischenwände 23 und 24 an geordnet, die sich bis kurz vor ihre Aus mündung in die Turbine 12 erstrecken. Die Zylinder 3 und 10 puffen durch die Auspuff rohre 15 und 22 in die äussere Hälfte und die Zylinder 4 und 9 durch Auspuffrohre 16 und 21 in die innere Hälfte des Sammel- rohres 13 aus. In die äussere Hälfte des zwei ten Sammelrohres 14 puffen die Zylinder 5 und 8 durch die Auspuffrohre 17 und 20, in die innere Hälfte die Zylinder 6 und 7 durch die Auspuffrohre 18 und 19.
Da bei einem Achtzylinderviertaktmotor auf 720 Kurbel winkel acht Zündungen entfallen, also je eine Zündung auf 90 Kurbelwinkel, ist aus Fig. 1 erichtlich, dass sich die Zündungen der Zylinder 3, 4, 10, 9 resp. 8, 6, 5, 7, die-in dasselbe Sammelrohr auspuffen, in je 180<B>0</B> Kurbelwinkel folgen.
Exhaust pipe on multi-cylinder * combustion engines with exhaust gas turbine. The invention relates to the gas line from multi-cylinder combustion engines with exhaust gas turbine. According to her, the exhaust gases from the combustion cylinders are passed through exhaust pipes separated over at least a length of two cylinder diameters in at least one collecting line.
Particularly in the case of high-speed engines, an intermediate wall can be arranged in the collector pipe up to the point where the pipe joins the turbine; and some of the combustion cylinders can exhaust on one side and the rest on the other side of the partition into the manifold. The exhaust pipes have one. relatively small cross-section in order to achieve a correspondingly higher speed in the same. Appropriately, only the exhaust pipes of cylinders whose exhausts follow each other in at least 1 $ 0 crank angle open into a collecting line.
With the subject of the invention one achieves the advantage that the exhaust processes in the cylinders, which are connected to the same collecting line, do not interfere so easily and the kinetic energy released at the beginning of the exhaust stroke is largely transferred directly to the turbine . Disturbing pressure fluctuations in the exhaust pipes can also be easily avoided since the number of exhausts in individual pipe sections is smaller.
In the accompanying drawings, an embodiment of the subject invention is shown on an eight-cylinder four-stroke engine. Fig. 1 is the front view, Fig. 2 is the plan view of the internal combustion engine; 3 to 6 show the connections of the exhaust pipes of the various cylinders to the manifolds; 7 shows the crank position. The firing order of the cylinders is indicated in Fig. 1 with Roman numerals.
In the figures, 1 denotes the eight-cylinder internal combustion engine, the cylinder with 3 to 10 and a generator with 2, which is driven by the internal combustion engine. 12 is the exhaust gas turbine that drives the supercharger 26. This conveys into the charging line 24. The exhaust pipes 15 to 22 of the combustion cylinders thus open into the collecting pipes 13 -resp. 14 that the smallest possible loss of speed occurs when overflowing.
In the collecting lines 13 and 14, partitions 23 and 24 are arranged, which extend into the turbine 12 until shortly before their opening. The cylinders 3 and 10 exhaust through the exhaust pipes 15 and 22 into the outer half and the cylinders 4 and 9 through exhaust pipes 16 and 21 into the inner half of the collecting pipe 13. The cylinders 5 and 8 puff through the exhaust pipes 17 and 20 into the outer half of the second manifold 14, and the cylinders 6 and 7 through the exhaust pipes 18 and 19 into the inner half.
Since eight ignitions are allotted to 720 crank angles in an eight-cylinder four-stroke engine, i.e. one ignition per 90 crank angle, it can be seen from FIG. 1 that the ignitions of cylinders 3, 4, 10, 9, respectively. 8, 6, 5, 7, which exhaust into the same manifold, each follow in 180 <B> 0 </B> crank angles.
