Description

Einspritz-Brennkraftmaschine mit Einspritzung des Brennstoffes durch mehrere Düsen in den Verbrennungsraum Es sind bereits Einspritz-Brennkraftmaschinen bekannt, bei denen der Brennstoff durch mehrere Düsen in den Verbrennungsraum eingespritzt wird. Bei diesen Maschinen sind die Zuleitungen zu den einzelnen Düsen in ständig offene Verbindung mit einem Brennstoffverteilstück gebracht, das seinerseits wiederum durch ein Brennstoffzufuhrventil an eine gemeinsame Druckleitung der Brennstoffpumpe angeschlossen ist. Es hat sich gezeigt, daß die Brennstoffsäulen der durch das Verteilstück ständig untereinander verbundenen Düsenzuleitungen bei solchen Maschinen derart ins Pendeln geraten können, daß sich der Brennstoff ungleich auf die verschiedenen Düsen verteilt und eine Störung des Einspritzvorganges die Folge ist.Injection internal combustion engine with fuel injection through Several nozzles in the combustion chamber There are already injection internal combustion engines known in which the fuel is injected through several nozzles into the combustion chamber will. In these machines, the feed lines to the individual nozzles are in constant brought open connection with a fuel distributor, which in turn through a fuel supply valve to a common pressure line of the fuel pump connected. It has been shown that the fuel columns through the distributor constantly interconnected nozzle feed lines in such machines can start to swing that the fuel differs unevenly on the different Distributed nozzles and a disruption of the injection process is the result.

Mit der Erfindung wird die Beseitigung dieses übelstandes bezweckt. Die Erfindung besteht darin, daß die Düsen an je eine in die Sitzfläche eines gemeinsamen Brennstoffverteilventils einmündende Leitung angeschlossen sind. Dadurch wird ein Pendeln des Brennstoffes verhindert und eine gleichmäßige Verteilung des Brennstoffes auf die verschiedenen Düsen sowie eine einwandfreie Einspritzung und Verbrennung des Brennstoffes erzielt.The aim of the invention is to eliminate this deficiency. The invention consists in that the nozzles each one in the seat of a common Fuel distribution valve opening line are connected. This becomes a Prevents the fuel from swinging and ensures that the fuel is evenly distributed on the various nozzles as well as perfect injection and combustion of the fuel achieved.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist auf der Zeichnung zur Darstellung gebracht. a ist ein Arbeitszylinder, b ein Kolben und c -ein Verbrennungsraum einer Einspritz-Brennkraftmaschine, bei welcher der durch die Leitung d von einer nicht gezeichneten Pumpe gelieferte Brennstoff über ein zentrales Brennstoffverteilventil e, das in bekannter Weise vom Brennstoff selbst angehoben wird, durch eine Mehrzahl von gleichmäßig verteilten Düsen/ in den Verbrennungsraum eingespritzt wird. Nach der Erfindung sind die einzelnen Düsenzuleitungen an je eine besondere, im Sitz des Ventils e angeordnete öffnung g angeschlossen, derart, daß jegliche Verbindung zwischen den einzelnen Zuleitungen unterbunden und ein Pendeln der darin sich befindenden Brennstoffsäulen unmöglich gemacht wird.An embodiment of the subject matter of the invention is shown in the drawing. a is a working cylinder, b a piston and c -a combustion chamber of an injection internal combustion engine, in which the fuel delivered through line d by a pump (not shown) via a central fuel distribution valve e, which is raised in a known manner by the fuel itself, through a A plurality of evenly distributed nozzles / is injected into the combustion chamber. According to the invention, the individual nozzle feed lines are each connected to a special opening g arranged in the seat of the valve e in such a way that any connection between the individual feed lines is prevented and the fuel columns located therein cannot oscillate.
