Description
Einspritzbrennkraftmaschine mit mindestens einer am Zylinderumfang angebrachten Vorkammer Die vorliegende Erfindung betrifft eine Einspritzbrennkraftmaschine mit mindestens einer am Zylinderumfang angebrachten Vorkammer, in welche die gesamte Brennstoffladung eingespritzt wird.Injection internal combustion engine with at least one on the cylinder circumference attached prechamber The present invention relates to an internal combustion engine with at least one prechamber attached to the cylinder circumference, into which the entire Fuel charge is injected.
Bei den bekannten Motoren dieser Art ist die Vorkammer in der Regel gleichachsig zum -Zylinder angeordnet; dabei ist, besonders wegn der Kolben sich in der Nähe seiner inneren Totlage befindet, der freie Weg für den aus der Vorkammer herauskommenden Strahl recht kurz. ' Gemäß der Erfindung wird dieser Weg recht lang und die Bauart ganz einfach, wenn man die Vorkammer oder Vorkammern, welche in an sich bekannter Weise durch eine zweckmäßig kurze Drosselstelle von unveränderlichem Ouerschnitt mit dem flachen scheibenförmigen Zylinderverbrennungsraum verbunden sind, mit ihrer Achse in" Richtung eines Zylinderdurchmesers anordnet, auf-dem auch die Einspritzdüsen und die Drosselstellen liegen.In the known engines of this type, the antechamber is usually arranged coaxially to the cylinder; is, especially wegn the piston itself is close to its inner dead position, the free path for the one out of the antechamber outgoing beam quite short. According to the invention, this path becomes quite long and the design is very simple, if you have the antechamber or antechambers, which in at known way by an expediently short throttle point of unchangeable Cross-section connected to the flat, disk-shaped cylinder combustion chamber are arranged with their axis in the direction of a cylinder diameter, on which also the injection nozzles and the throttling points are located.
Auf der Zeichnung sind zwei Ausführungsbeispiele 'des Erfindungsgegenstandes im Längsschnitt durch einen Zylinder und Kolben dargestellt.The drawing shows two exemplary embodiments of the subject matter of the invention shown in longitudinal section through a cylinder and piston.
Abb. i zeigt das erste Beispiel; dabei ist nur eine einzige Vorkammer seitlich am Zylinder angeordnet.Fig. I shows the first example; there is only a single antechamber arranged on the side of the cylinder.
Beim zweiten Beispiel nach Abb. a sind zwei Vorkammern am Zylinder vorgesehen. In beiden Abbildungen bedeutet a eine Einspritzdüse, b eine seitlich am Zylinderumfang angeordnete Vorkammer und c eine kurze Drosselstelle von unveränderlichem Querschnitt, welche die Verbindung zwischen der dazugehörigen Vorkammer und dem Zylinderraum d herstellt. Der im Zylinder hin und her gehende Kolben ist mit g bezeichnet und die Ein- ünd Äuslaßventile mit 'e und f. In the second example according to Fig. A, two antechambers are provided on the cylinder. In both figures, a denotes an injection nozzle, b a prechamber arranged on the side of the cylinder circumference, and c a short throttle point of invariable cross-section, which establishes the connection between the associated prechamber and the cylinder space d. The piston moving back and forth in the cylinder is designated with g and the inlet and outlet valves with 'e and f.
Beim ersten Beispiel wird der gesamte Brennstoff durch die Düse a in die Vorkam-mer b gegen die Drosselstelle c hin eingespritzt. Die Verlängerung der mit der Düsenachse und der Achse der Drosselstelle zusammenfallenden Achse der Vorkammer schneidet die Zylinderachse, so daß also die Spritzrichtung der Düse mit einem Zylinderdurchmesser des scheibenförmigen Brennraums zusammenfällt.In the first example, all of the fuel is injected through the nozzle a into the antechamber b towards the throttle point c. The extension of the axis of the prechamber coinciding with the nozzle axis and the axis of the throttle point intersects the cylinder axis, so that the spray direction of the nozzle coincides with a cylinder diameter of the disk-shaped combustion chamber.
In jede der beiden beim zweiten Beispiel nach Abb. a vorgesehenen gleich großen Vorkammern b wird die Hälfte der für einen Arbeitshub benötigten Brennstoffmenge eingespritzt.In each of the two provided in the second example according to Fig. A antechamber b of the same size is half the amount of fuel required for one working stroke injected.
Bemerkenswert beim zweiten Beispiel ist noch, daß die beiden einander gegenüberliegenden Vorkammern in der Höhe etwas gegeneinander versetzt sind.It is also noteworthy in the second example that the two are mutually exclusive opposite antechambers are slightly offset from one another in height.
