Description

Die Erfindung betrifft eine nach dem Otto-Verfahren im Zweitakt arbeitende Einspritzbrennkraftmaschine, deren Einspritzdüse bzw. -düsen aus der Kolbenlaufbahn heraus in den Hubraum des Kolbens einmünden.The invention relates to a two-stroke operating according to the Otto process Internal combustion engine, its injection nozzle or nozzles from the piston path open out into the displacement of the piston.

Es ist bekannt, die Einspritzdüse so anzuordnen, das die Einspritzung vom Zylinderdeckel gegen den aufsteigenden Sammelspülstrom erfolgt und die Zündkerze in der Wirbelebene des Sammelspülstromes angeordnet ist. Die Kraftstoffstrahlen verlaufen dabei parallel zur Kolbenlaufbahn dem nach oben gerichteten Sammelspülstrom entgegen.It is known to arrange the injection nozzle so that the injection from the cylinder cover against the rising collective flushing flow and the spark plug is arranged in the vortex plane of the collecting flush flow. The fuel jets run parallel to the piston path of the upwardly directed collective flushing flow opposite.

Es wurde ferner schon der Vorschlag gemacht, die Einspritzdüse in die Zylinderwand einzubauen, so das die die Einspritzdüse verlassenden Kraftstoffstrahlen die Kolbenlaufbahn des Zylinders durchdringen, während sie in den Hubraum für den Kolben eintreten. Die Kraftstoffstrahlen treten von unten nach oben ansteigend in den Hubraum des Kolbens ein, so das der Spülstrom als auch der Kraftstoffstrahl eine nach oben gerichtete Vertikalkomponente haben.The suggestion has also been made to convert the injector into to install the cylinder wall, so that the fuel jets leaving the injector penetrate the piston path of the cylinder while they are in the displacement for the Piston enter. The fuel jets rise from bottom to top the displacement of the piston, so that the flushing flow as well as the fuel jet have an upward vertical component.

Nach der Erfindung haben demgegenüber die Kraftstoffstrahlen die Richtung auf die Öffnungen der Frischluftzuführungskanäle.According to the invention, on the other hand, the fuel jets have the direction on the openings of the fresh air supply ducts.

Der Vorteil der neuen Anordnung gegenüber dem Bekannten besteht darin, das die Frischluft sofort nach dem Eintreten in den Zylinderraum mit den Kraftstoffstrahlen in Berührung gebracht werden, also einem Zeitpunkt, an dem der Frischluftstrom noch zusammengefast ist und eine verhältnismäßig hohe Strömungsgeschwindigkeit und damit eine gute Zerstäuberwirkung auf die Kraftstofftröpfchen hat.The advantage of the new arrangement over the familiar is that that the fresh air immediately after entering the cylinder chamber with the fuel jets be brought into contact, i.e. a point in time at which the fresh air flow is still is collapsed and a relatively high flow rate and thus Has a good atomizing effect on the fuel droplets.

Darüber hinaus wird empfohlen, Kraftstoffstrahlen zusätzlich in Richtung auf die Zündkerzen zu spritzen.In addition, it is recommended to additionally point fuel jets in the direction to splash on the spark plugs.

In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, die Einspritzdüse bzw. -düsen so zu richten, das die aus ihr austretenden Kraftstoffstrahlen die Frischluftströme oder Teile davon kreuzen.In a further embodiment of the invention, it is proposed that the injection nozzle or nozzles in such a way that the fuel jets exiting from it flow through the fresh air or cross parts of it.

In der Zeichnung sind Ausführungsbeispiele dargestellt. Es zeigt Abb. i einen Vertikalschnitt durch den Zylinder einer Einspritzbrennkraftmaschine und die Abb. 2 bis 4 Querschnitte nach Linie A-.A der Abb. -i, jedoch mit unterschiedlicher Anordnung der Einspritzdüsen.Exemplary embodiments are shown in the drawing. It shows fig. i a vertical section through the cylinder of an internal combustion engine and Fig. 2 to 4 cross-sections along line A-.A of Fig. -i, but with different Arrangement of the injection nozzles.

In der Wand des Zylinders i sind die Einspritzdüsen 2, 3, 4, 5, 6, 7 gelagert, wobei die Einspritzdüsen 4,5 bzw. 6,7 zusammenwirken können. Die Einspritzdüsen richten die Kraftstoffstrahlen 8 auf die Mündung der Spülstromkanäle 9. Der Auslaßkanal ist mit io bezeichnet. Die Einspritzdüsen 3, 4, 5 sind so gerichtet, das sie Spülströme durchschneiden.The injection nozzles 2, 3, 4, 5, 6, 7 are mounted in the wall of the cylinder i, whereby the injection nozzles 4, 5 and 6, 7 can interact . The injection nozzles direct the fuel jets 8 onto the mouth of the flushing flow channels 9. The outlet channel is denoted by io. The injection nozzles 3, 4, 5 are directed so that they cut through flushing flows.
