Patentiert im Deutschen Reiche vom 9. Juli 1910 ab.Patented in the German Empire on July 9, 1910.
Die vorliegende Erfindung betrifft eine Einspritzvorrichtung, die sich ebensogut für Maschinen eignet, welche mit Selbstzündung wie der Dieselmotor arbeiten, wie für solche, die eine besondere Zündvorrichtung erfordern. Auch gestattet sie die Benutzung der schwersten Teeröle, von Rohnaphta und Massut.The present invention relates to an injection device, which is just as suitable for machines that work with compression ignition like the diesel engine, as for those that require a special ignition device. It also allows the heaviest ones to be used Tar oils, from Rohnaphta and Massut.
An dem Zylinderkopf der Maschine ist ein Gehäuse A angeordnet, das drei Ventile enthält (vgl. Fig. i), ein gesteuertes Druckluftventil D, ein selbsttätiges, federbelastetes Brennstoffventil C und ein gesteuertes Zerstäubungsventil B. A housing A is arranged on the cylinder head of the machine and contains three valves (see Fig. I), a controlled compressed air valve D, an automatic, spring-loaded fuel valve C and a controlled atomization valve B.
Das Druckluft ventil D mündet in eine Druckluftkammer F, das Brennstoffventil C in eine Brennstoffkammer E. Beide Kammern sind sackartig ausgebildet und stehen durch je einen Kanal H1 bzw. H2 mit der Einspritzöffnung in Verbindung. Andererseits sind sie durchThe compressed air valve D opens into a compressed air chamber F, the fuel valve C into a fuel chamber E. Both chambers are sack-like and are each connected to the injection port through a channel H 1 or H 2. On the other hand, they are through
ao eine Querbohrung /, die teils im Zerstäubungsventil, teils im Gehäuse verläuft, untereinander verbunden. Endlich besitzt das Zerstäubungsventil B eine Längsbohrung L, die an ihrem unteren Ende in eine feine öffnung G ausläuft. ao a cross hole /, which runs partly in the atomizing valve and partly in the housing, connected to one another. Finally, the atomization valve B has a longitudinal bore L which ends in a fine opening G at its lower end.
Beim Saughube des Motors pflanzt sich der im Zylinderinnern herrschende Unterdruck durch die Bohrungen L und / nach dem Raum E fort, und es öffnet sich infolgedessen das Brennstoffventil C.At the intake of the engine, the negative pressure prevailing inside the cylinder is propagated through the bores L and / to the space E , and the fuel valve C opens as a result.
, Der Brennstoff fließt von einem hochstehenden Behälter durch das geöffnete Ventil C nach dem Boden der Brennstoff kammer E. Während des Verdichtungshubes pflanzt sich der im Zylinder herrschende Druck ebenso wie 45 The fuel flows from an upright container through the open valve C to the bottom of the fuel chamber E. During the compression stroke, the pressure in the cylinder builds up, as does 45
beim Saughub durch die Bohrungen L und / in die Kammern E und F fort, so daß in ihnen am Ende des Verdichtungshubes nahezu die gleiche Spannung wie im Zylinder herrscht. Sobald der Arbeitskolben in die Nähe des Totpunktes gekommen ist, wird das Druckluftventil D geöffnet. Die Druckluft, die wesentlich höher verdichtet ist als die Verbrennungsluft im Zylinder, tritt von der Kammer F durch die Bohrung / nach der Brennstoffkammer E über, und da die öffnung G bedeutend kleiner ist als der Zuflußquerschnitt des Druckluftventils, so herrscht in Raum E und F ein wesentlich höherer Druck wie im Verdichtungsraum des Zylinders.during the suction stroke through the bores L and / into the chambers E and F , so that in them at the end of the compression stroke there is almost the same tension as in the cylinder. As soon as the working piston has come close to dead center, the compressed air valve D is opened. The compressed air, which is much more highly compressed than the combustion air in the cylinder, passes from the chamber F through the bore / to the fuel chamber E , and since the opening G is significantly smaller than the inflow cross-section of the compressed air valve, space E and F prevails a much higher pressure than in the compression chamber of the cylinder.
Kurz nach dem öffnen des Druckluftventils D wird auch das Zerstäubungsventil B gehoben, die auf dem Brennstoffspiegel lastende Druckluft schiebt den Brennstoff vor sich her, und es werden Brennstoff und Luft durch die Kanäle H1 und H2 (Fig. 2) in bekannter Welse tangential der Einspritzöffnung zugeführt, so daß sie unter heftiger Wirbelbewegung in den Explosionsraum gelangen, wo sie sich mit weiterer Luft vermengen und an der Verbrennung teilnehmen. Aus der öffnung G tritt ein feiner Luftstrahl aus, der die Zerstäubung des Brennstoffes unterstützt und nach Abschluß des Zerstäubungsventils den letzten Brennstoffrest in das Zylinderinnere einführt.Shortly after the compressed air valve D is opened, the atomizing valve B is also lifted, the compressed air, which loads the fuel level, pushes the fuel in front of it, and fuel and air are tangential through the channels H 1 and H 2 (FIG. 2) in a known manner fed to the injection opening so that they get into the explosion chamber with a violent whirling motion, where they mix with further air and take part in the combustion. A fine air jet emerges from the opening G , which supports the atomization of the fuel and, after the atomization valve has been closed, introduces the last remaining fuel into the interior of the cylinder.
