Description

Aufgeladene Kolbenbrennkraftmaschine mit Abgasturbine Die Erfindung bezieht sich auf aufgeladene Kolbenbrennkraftmaschinen mit Abgasturbine, insbesondere Dieselmotor.Supercharged piston internal combustion engine with exhaust gas turbine The invention relates to supercharged piston internal combustion engines with exhaust gas turbines, in particular Diesel engine.

Es ist bereits bekannt, in die Auspuffleitung von Kolbenbrennkraftmaschinen zwischen den Motor und die Turbine eine Ejektoreinrichtung vorzusehen. Auch ist es bereits bekannt, den aus den Zylindern der Brennkraftmaschine austretenden Verbrennungsgasen verdichtete Luft zuzuführen. Nach der Erfindung steht die Ejektorkammer bzw. die Ejektorkammern über ein Rohr mit der die Abgase aus der Turbine abführenden Leitung in Verbindung. Dieses hat den Vorteil, daß ohne besondere Zuführung von Frischluft die Auspuffgase in erhöhtem Maße abgesaugt werden. Die Gesamtmenge der Auspuffgase wird demnach erhöht und somit die Leistung gesteigert. 1n Verbindung mit dieser Ausführungsform liegt es im Rahmen der Erfindung, die einzelnen Ejektorkammern untereinander durch eine Leitung zu verbinden. Solche Verbindungsleitungen der einzelnen Ejektorkammern untereinander sind an sich bekannt, so daß diese Maßnahme hier nur in Verbindung mit dem Gegenstand des Hauptanspruches unter Schutz stehen soll.It is already known in the exhaust line of reciprocating internal combustion engines to provide an ejector device between the engine and the turbine. Also is it is already known, the combustion gases emerging from the cylinders of the internal combustion engine to supply compressed air. According to the invention, the ejector chamber or the Ejector chambers via a pipe with the pipe leading away the exhaust gases from the turbine in connection. This has the advantage that there is no special supply of fresh air the exhaust gases are extracted to a greater extent. The total amount of exhaust gases is therefore increased and thus the performance increased. 1n connection with this Embodiment, it is within the scope of the invention, the individual ejector chambers with each other to be connected by a line. Such connecting lines of the individual ejector chambers each other are known per se, so that this measure is only in connection here with the subject matter of the main claim should be under protection.

Auch können erfindungsgemäß die Ejektordiffusoren mit einer bzw. mehreren an sich bekannten Rückschlagklappen versehen sein. Das hat den Vorteil einer größeren Stabilisierung der Druckwellen in der Sammelleitung, durch welche die Auspuffgase des Motors zu der Turbine geleitet werden. Es ist bereits bekannt, die Ejektordiffusoren in eine die Auspuffgase vom Motor zur Turbine abführende Sammelleitung ausmünden zu lassen.According to the invention, the ejector diffusers can also have one or more be provided known check valves. That has the advantage of a larger one Stabilization of the pressure waves in the manifold through which the exhaust gases of the engine can be directed to the turbine. It is already known the ejector diffusers open into a collecting line leading away the exhaust gases from the engine to the turbine allow.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt, wo Fig. 1 die Ansicht eines Mehrzylindermotors von der Seite der Auspuffleitung im Teilschnitt zeigt; in Fig. 2 sehen wir die Ansicht von oben auf einen Teil des Motors und Fig. 3 stellt einen Querschnitt durch den Zylinderkopf des Motors mit Auspuffleitung dar.An exemplary embodiment of the invention is shown schematically in the drawing where Fig. 1 is a view of a multi-cylinder engine from the side of the exhaust line shows in partial section; in Fig. 2 we see the top view of part of the Engine and Fig. 3 shows a cross section through the cylinder head of the engine Exhaust pipe.

An den Auspuffkanal 1 (Fig. 3) im Kopf 2 jedes Zylinders des Motors ist anstatt der üblichen Zylinderleitung eine Ejektorvorrichtung E angeschlossen, die aus einer Düse 4, einer Ejektorkammer 5 und aus einem Diffusor 6 besteht. Die Düse 4 des Ejektors ist unmittelbar an den Auspuffkanal 1 im Zylinderkopf angeschlossen, wogegen der Diffusor 6 des Ejektors mit seinem breiteren Ende in die Sammelleitung 8 ausmündet, welche die Abgase aus allen Motorzylindern zur Turbine 10 abführt. Die Mündungen der Eiektoren E in die Sammelleitung 8 sind mit einer Rückschlagklappe 18 versehen. Die Turbine 10 treibt ein Turbogebläse an, welches dem Motor die erforderliche Spül- und Ladeluft liefert. Die Ejektorkammern 5 sind untereinander durch eine Rohrleitung 12 verbunden, welche verlängert und durch das Rohr 14 mit der die Abgase aus der Turbine abführenden Leitung 16 verbunden ist.Instead of the usual cylinder line, an ejector device E, which consists of a nozzle 4, an ejector chamber 5 and a diffuser 6, is connected to the exhaust duct 1 (FIG. 3) in the head 2 of each cylinder of the engine. The nozzle 4 of the ejector is directly connected to the exhaust duct 1 in the cylinder head, whereas the wider end of the diffuser 6 of the ejector opens into the collecting line 8 , which discharges the exhaust gases from all engine cylinders to the turbine 10 . The mouths of the Eiectors E in the collecting line 8 are provided with a non-return valve 18 . The turbine 10 drives a turbo fan, which supplies the engine with the necessary scavenging and charge air. The ejector chambers 5 are connected to one another by a pipe 12 , which is elongated and connected by the pipe 14 to the pipe 16 discharging the exhaust gases from the turbine.

Nach dem öffnen des Auspuffventils strömt die Abgaswefle durch den Kanal 1 im Zylinderkopf direkt in die Düse 4 des Ejektors E. Durch den Gasauslauf von erhöhter Geschwindigkeit aus der Düse 4 und durch den in der Ejektorkammer 5 entstandenen Unterdruck wird ein Teil der Abgase aus der Auspuffleitung 16 hinter der Turbine 10 angesaugt. Durch die gegenseitige Verbindung der Ejektorkammern 5 wird hinter den Auspuffventilen durch das Absaugen ein niedrigerer Gegendruck gebildet. Dadurch verringert sich die Arbeit des Kolbens beim Herausdrücken der Gase in dem arbeitsgemäß vorangehenden Zylinder, wo das Auspuffventil geöffnet ist. Die kinetische Energie der Abgase wird in dem Ejektor E in Druck umgesetzt, und die um die Ansaugmenge aus dem Auspuff hinter der Turbine volumetrisch vergrößerten Abgase werden in die Sammelleitung 8 herausgedrückt. Beim Druckabfall am Ende des Diffusors 6 unter den Wert des Druckes in der Sammelleitung 8 wird die Rückschlagklappe 18 automatisch geschlossen und verhindert das Eindringen der Gase zurück in den Ejektor.After opening the exhaust valve, the exhaust gas flows through channel 1 in the cylinder head directly into nozzle 4 of ejector E. Due to the increased speed of gas out of nozzle 4 and the negative pressure created in ejector chamber 5, some of the exhaust gases are released from the exhaust line 16 sucked in behind the turbine 10. Due to the mutual connection of the ejector chambers 5, a lower counter pressure is formed behind the exhaust valves by the suction. This reduces the work of the piston in pushing out the gases in the operationally preceding cylinder where the exhaust valve is open. The kinetic energy of the exhaust gases is converted into pressure in the ejector E, and the exhaust gases, which are volumetrically increased by the intake quantity from the exhaust pipe behind the turbine, are pressed out into the manifold 8 . If the pressure at the end of the diffuser 6 drops below the value of the pressure in the collecting line 8 , the non-return valve 18 is automatically closed and prevents the gases from penetrating back into the ejector.
