Description
Die Erfindung betrifft eine Einspritzbrennkraftmaschine, welche im höheren Belastungsbereich mit Aufladung betrieben wird und die zwei Einspritzvorrichtungen aufweist, von denen eine im niederen unaufgeladenen Belastungsbereich von Null bis zu der dabei erforderlichen Höchstmenge geregelt wird und von denen die andere eine kleine konstante Einspritzmenge einspritzt, während im höheren Belastungsbereich die zuletzt genannte Einrichtung von der kleinen Voreinspritzmenge bis zur Höchstmenge geregelt wird, wobei die erstgenannte Vorrichtung konstant ihre höchste Menge einspritzt.The invention relates to an internal combustion engine which is in the higher load range is operated with supercharging and the two injectors one of which is in the low uncharged load range from zero to to the maximum amount required is regulated and of which the other one injects a small constant injection quantity, while in the higher load range the last-mentioned device from the small pre-injection quantity to the maximum quantity is regulated, the first-mentioned device constantly injecting its highest amount.
Bei einer Einspritzbremikraftmaschine der vorbeschriebenen Art macht die Anordnung von zwei Brennstoffeinspritzventilen eine solche Ausgestaltung des Verbrennungsraumes erforderlich, daß über den gesamten Betriebsbereich eine gleichmäßig gute Mischung zwischen Brennstoff undLuft herbeigeführt wird. Dies wird gemäß der Erfindung erreicht durch einen doppelkegelförmigen, in den Kegelspitzen die Einspritzventile aufweisenden Verbrennungsraum, dessen Achse senkrecht zur Zylinderachse verläuft, der am äußeren Umfang über eine vorzugsweise in der Ebene des größten Durchmessers #,egetiüber derZylinderachseversetzte Verbindungsöffnung mit dem Zylinder in Verbindung steht, wobei die vorzugsweise gegeneinander versetzten Brennstoffstrahlen etwa in Richtung des Kegelmantels gegen den größten Brennraumumfang hin gerichtet sind.In an injection brake engine of the type described above the arrangement of two fuel injectors such an embodiment of the Combustion chamber required that over the entire operating range a uniform a good mixture of fuel and air is achieved. This is done according to the Invention achieved by a double-cone-shaped, in the cone tips, the injection valves having combustion chamber, the axis of which is perpendicular to the cylinder axis, the one on the outer circumference over a preferably in the plane of the largest diameter #, egeti connection opening offset above the cylinder axis in connection with the cylinder stands, with the fuel jets, which are preferably offset from one another, approximately in Direction of the cone shell are directed towards the largest combustion chamber circumference.
In der Zeichnung ist der erfindungsgemäße Verbrennungsraum beispielsweise dargestellt.In the drawing, the combustion chamber according to the invention is for example shown.
Abb. i zeigt den Verbrennungsraum senkrecht geschnitten; Abb. 2 zeigt einen Schnitt nach der Linie 11-I1 in Abb. i. In Abb. a ist der Schnitt nach Abb. i durch die Linie 1-I angedeutet.Fig. I shows the combustion chamber cut vertically; Fig. 2 shows a section along the line 11-I1 in Fig. i. In fig.a the section according to fig. i indicated by the line 1-I.
Der in den Abb. i und 2 dargestellte Verbrennungsraum i weist die Form eines Doppelkegels auf, dessen Achse senkrecht zur Zylinderachse verläuft. Der Brennraum steht an einer Stelle seines äußeren Umfangs mit dem Zylinder in Verbindung. Die Verbindungsöffnung ist vorzugsweise gemäß Abb. a in der Ebene des größten Durchmessers des Brennraumes gegenüber der Zylindermitte versetzt, so daß die durch den Pfeil angedeutete Wälzbewegung zustande kommt. Die beidenEinspritzventilea und 3 sind einander gegenüber in den Spitzen des doppelkegeligen Brennraumes angeordnet und spritzen die Brennstoffstrahlen etwa in Richtung der Kegelmäntel gegeneinander. Die Spritzöffnungen der Einspritzventile sind vorzugsweise gegeneinander versetzt, so daß das eine Ventil zwischen die Brennstoffstrahlen des anderen Ventils spritzt.The combustion chamber i shown in Figs. I and 2 has the Shape of a double cone, the axis of which is perpendicular to the cylinder axis. The combustion chamber is connected to the cylinder at one point on its outer circumference. The connection opening is preferably in the plane of the largest diameter as shown in Fig. A of the combustion chamber is offset from the center of the cylinder, so that the arrow indicated by the indicated rolling movement comes about. The two injection valves a and 3 are arranged opposite one another in the tips of the double-conical combustion chamber and the fuel jets spray against each other approximately in the direction of the cone shells. The injection openings of the injection valves are preferably offset from one another, so that one valve injects between the fuel jets of the other valve.
