Description

Einspritzbrennkraftmaschine Die Erfindung betrifft eine Einspritzbrennkraftmaschine mit einer gegen Ende des Verdichtungshubs nahezu die gesamte oder einen großen Teil der Verbrennungsluft aufnehmenden Wälzkammer, die mit dem Zylinderraum durch einen Ül)erströmkana1 verbunden ist, wobei der Kraftstoff in die Wälzkammer in Richtung auf die Mändung eines Nebenkanals eingespritzt wird, der die Wälzkammer mit dem Innern des Überström'kanals verbindet, gegenüber letzterem einen wesentlich kleineren Querschnitt aufweist und geradlinig verlaufend in die Wälzkammer entgegen dem darin kreisenden Strom reiner oder der mit Kraftstoff durchsetzten Luft mündet.Injection internal combustion engine The invention relates to an injection internal combustion engine with one near the end of the compression stroke almost all or a large part the combustion air receiving rolling chamber, which is connected to the cylinder space by a Ül) erströmkana1 is connected, the fuel in the rolling chamber towards is injected onto the mouth of a secondary channel that connects the rolling chamber with the Inside the Überström'kanals connects, compared to the latter a much smaller one Has cross-section and running in a straight line in the rolling chamber opposite to that therein circulating stream purer or the air interspersed with fuel opens.

Eine solche Brennkraftmas.chine ist bekannt. Ihre vorteilhafte Wirkung beruht darauf, daß nach Einspritzbeginn insbesondere i.in unteren Drehzahlbereich der Maschkie ein Teil des eingespritzten Kraftstoffes durch den Nebenkanal in den Hauptkanal übertritt und damit in die in die Wälzkammer eintretende verdichtete Luft gelangt, wodurch das Anlaßverhalten der betreffenden Maschine erheblich verbessert wird. Nach Umkehr der Strömungsrichtungen im Hauptkanal wird. im Nebenkanal noch vorhandener Kraftstoff infolge des in der Wälzkammer herrschenden hohen Druckes in den Hauptkanal und damit in die in den Zylinderraum übertretenden heißen Gase geschleudert. Erfindungsgemäß ist der Hauptkanal im Bereich der Mündung des Nebenkanals eingeschnürt. Diese Einschnürung hat dien Vorteil, daß sowohl gegen Ende der Verdichtung als auch nach Umkehr der Strömungsrichtung durch starkes Absenken des Druckes in dem Nebenkanal für den Übertritt von Kraftstoff aus dein Nebenkanal in den Hauptkanal bessere Voraussetzungen geschaffen sind.Such a combustion engine is known. Your beneficial effect is based on the fact that after the start of injection in particular i.in the lower speed range the Maschkie a part of the injected fuel through the secondary channel into the Main channel crosses and thus compressed into the one entering the rolling chamber Air gets in, which significantly improves the starting behavior of the machine in question will. After reversing the directions of flow in the main channel. in the secondary channel Fuel available as a result of the high pressure in the rolling chamber into the main channel and thus into the hot gases passing into the cylinder chamber hurled. According to the invention, the main channel is in the area of the mouth of the secondary channel constricted. This constriction has the advantage that both towards the end of the compaction as well as after reversing the direction of flow by greatly reducing the pressure in the secondary channel for the passage of fuel from your secondary channel into the main channel better conditions are created.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

In der Zeichnung sind diie Wälzkammer mit 1, das Kraftstoffei.nspritzventil mit 2 und der den Zylinderraum 3 mit der Wälzkammer 1 verbindende, tangentia1 in diese eiil@mfndende überströmkanal mit 4 bezeiclinet. Außer diesem Hauptkanal 4 ist noch ein Nebenkanal 5 wesentlich kleineren Querschnittes vorhanden, der von der Wälzkammer ausgehend, in dien Hauptkanal 4 mündet. Der Kraftstoffstrahl ist auf die Mündung des Nebenkanals 5 gerichtet, so daß gegen Ende der Verdichtung insbesondere im unteren Drehzahlbereich Kraftstoff durch denn Nebenkanal s in den Hauptkanal 4 gelangt. Im Bereich der Mündung des Nebenkanals 5 im Hauptkanal 4 ist letzterer eingeschnürt, wodurch der Übertritt von Kraftstoff aus dem Nebenkanal in den Hauptkanal sowohl gegen Ende der Verdichtung als auch beim Ausströmen der heißen Gase aus der «'älzkanimer infolge der im Nebenkanal 5 erzwungenen Drucksenkung begünstigt wird.In the drawing are the rolling chamber with 1, the fuel injection valve with 2 and the tangentia1 in this eiil @ opening overflow duct is marked with 4 lines. Besides this main channel 4 there is still a secondary channel 5 with a much smaller cross-section, which is of starting from the rolling chamber into which the main channel 4 opens. The fuel jet is directed at the mouth of the secondary channel 5, so that towards the end of the compression in particular in the lower speed range, fuel through the secondary channel s into the main channel 4 arrives. The latter is in the area of the mouth of the secondary channel 5 in the main channel 4 constricted, whereby the passage of fuel from the secondary channel into the main channel both towards the end of compression and when the hot gases flow out of the "'Älzkanimer is favored as a result of the pressure reduction forced in the secondary channel 5.
