Description

Einspritzbrennitraftmaschine Vorliegende Erfindung betrifft eine weitere Ausgestaltung der im Patent 498 699 dargestellten Verbrennungskraftmaschine mit zwangläufiger Luftführung in einem kreisringförmigen Verbrennungsraum, und zwar kennzeichnet sich die Erfindung dadurch, daß in dem in den Verbrennungsraum ragenden Ende der Einspritzdüse radiale Bohrungen angeordnet sind, wodurch bei der in obiger Patentschrift angegebenen zwangläufigen Luftführung im Sinne des Brennstoffstrahles dem Brennstoff vor Austritt aus der Düse Verbrennungsluft zugeführt wird. Radiale Bohrungen in der Einspritzdüse sind an und für sich bekannt. Diesen gegenüber unterscheidet sich vorliegende Erfindung dadurch, daß dieselben in Verbindung mit der zwangläufigen Führung der Verbrennungsluft angewandt und nach dem Verbrennungsraum düsenförmig erweitert sind. Durch diese Ausbildung der Einspritzdüse wird eine kräftige Durchwirbelung des Brennstoffes mit Verbrennungsluft beim Austritt aus der Düse erzielt.Fuel Injection Engine The present invention relates to another Design of the internal combustion engine shown in patent 498 699 with forced air flow in a circular combustion chamber, namely The invention is characterized in that in the protruding into the combustion chamber Radial bores are arranged at the end of the injection nozzle, whereby in the case of the above Patent specified compulsory air flow in the sense of the fuel jet Combustion air is supplied to the fuel before it exits the nozzle. Radial Holes in the injection nozzle are known per se. This differs from this The present invention in that the same in connection with the inevitable Guiding the combustion air applied and after the combustion chamber nozzle-shaped are expanded. This design of the injection nozzle creates a strong turbulence of the fuel achieved with combustion air as it emerges from the nozzle.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, und zwar zeigt Abb. i die Anordnung im Vertikalschnitt, Abb. 2 einen Querschnitt nach der Linie A-A der Abb. i.In the drawing, an embodiment of the invention is shown, namely Fig. i shows the arrangement in vertical section, Fig. 2 shows a cross section according to the line A-A of Fig. i.

Der Brennstoff wird nach Anheben der Düsennadel bzw. des Abschlußv entils i oder direkt von einer Brennstoffpumpe durch eine Bohrung 2 mit beträchtlicher Geschwindigkeit in den Verbrennungsraum 3 gespritzt. Bei der ringförmigen Ausbildung des Verbrennungsraumes (Abb. i) entsteht am Ende des Verdichtungshubes des Kolbens 7 in der Pfeilrichtung eine kräftige Luftströmung, welche die Luft in die trichterförmigen Aussparungen 8 der Löcher 4 treibt. Die Aussparungen 8 sind, wie aus Abb. 2 ersichtlich ist, so ausgestaltet, daß die Luftströmung nur an den Stellen, wo die Öffnungen 8, 4. sich befinden, teilweise eingefangen wird. Außerdem wird durch die Strahlwirkung des Brennstoffes die verdichtete heiße Luft angesaugt und mit dem Brennstoff vermischt, wodurch dessen frühzeitige Entzündung und gute Verteilung bewirkt wird.The fuel is after lifting the nozzle needle or the Abschlussv entils i or directly from a fuel pump through a bore 2 with considerable Speed injected into the combustion chamber 3. With the ring-shaped training of the combustion chamber (Fig. i) is created at the end of the piston compression stroke 7 in the direction of the arrow a strong air flow, which the air in the funnel-shaped Recesses 8 of the holes 4 drives. The recesses 8 are, as can be seen from FIG is designed so that the air flow only in the places where the openings 8, 4. are located, is partially captured. In addition, the radiation effect of the fuel, the compressed hot air is sucked in and mixed with the fuel, causing its early inflammation and good distribution.
