Description
Brennstoffeinspritzeinrichtung für Breunkraftmaschinen. Die Erfindung betrifft eine Brennstoffein- spritzeinrichtung für Brennkraftrnaschinen, deren Einspritzorgan nicht nur vorn Brenn stoff beim Passieren des Einspritzkanals ge kühlt wird, und besteht darin, dass ein vom Einspritzkanal getrennter Kühlraum des Ein- spritzorgans in die Saugleitung der Brenn stoffpumpe eingeschaltet ist, so dass es von dem durch die Brennstoffpumpe angesaugten Brennstoff durchströmt wird.
Ein Ausführungsbeispiel des Erfindungs gegenstandes ist auf der Zeichnung im Schnitt zur Darstellung gebracht.
a ist der Arbeitszylinder, b der Arbeits kolben und c der Zylinderdeckel einer nicht weiter gezeichneten Einspritzbrennkraftma- schine, in deren Verbrennungsraum d der Brennstoff durch eine gekühlte Einspritzdüse e mit einem Einspritzkanal, der sich kurz vor der Ausmündung verzweigt, mittelst der Brennstoffpumpe f eingespritzt wird, deren Saugleitung mit g und deren Druckleitung mit lt bezeichnet ist. Der Kühlraum i der Einspritzdüse ist durch Kanäle<I>k</I> und<B>1</B> so in die Saugleitung der Pumpe eingebaut, dass in ihm der zur Pumpe strömende Brennstoff als Kühlmittel wirkt.
Dadurch wird das Einspritz- organ unter Vermeidung sowohl einer Rück kühlung des Kühlmittels, als auch einer Unter drucksetzung des Kühlraumes mit dem Brenn stoff selbst wirksam gekühlt. Natürlich könnte das Einspritzorgan auch mehrere getrennte Einspritzkanäle besitzen.
Fuel injection device for fuel engines. The invention relates to a fuel injection device for internal combustion engines, the injection element of which is not only cooled by the fuel when it passes through the injection channel, and consists in that a cooling chamber of the injection element separated from the injection channel is switched into the suction line of the fuel pump so that the fuel drawn in by the fuel pump flows through it.
An embodiment of the subject invention is shown on the drawing in section.
a is the working cylinder, b the working piston and c the cylinder cover of an internal combustion engine (not shown), into the combustion chamber d of which the fuel is injected by means of the fuel pump f through a cooled injection nozzle e with an injection channel that branches off shortly before the outlet whose suction line is denoted by g and whose pressure line is denoted by lt. The cooling space i of the injection nozzle is built into the suction line of the pump through channels <I> k </I> and <B> 1 </B> in such a way that the fuel flowing to the pump acts as a coolant in it.
As a result, the injector is effectively cooled with the fuel itself, while avoiding both back cooling of the coolant and pressurization of the cooling space. Of course, the injection element could also have several separate injection channels.
