Description
KAISERLICHESIMPERIAL
PATENTAMT,PATENT OFFICE,
Mit dieser Neuerung soll in der Hauptsache die vollkommene und rufsfreie Verbrennung von Staubstrahlen schwerer Erdöle, Theere, sowie flüssigen Brennstoffen überhaupt in einer Kraftmaschine erreicht werden, welche nach Art der heutigen Gasmaschinen wirkt. Die gröfste Schwierigkeit bietet hierbei die geringe Ausdehnung des Verbrennungsraumes, infolge derselben die zerstäubende Luft (die behufs einer guten Zertheilung der OeIe nothwendig eine grofse Ausflufsgeschwindigkeit besitzen mufs) einen mehr oder minder grofsen Theil der Oelpartikelchen gegen die Wandungen wirft, ehe sie von der sich nur langsam entwickelnden Flamme erreicht werden. Die mittlere Geschwindigkeit des Staubstrahles innerhalb des Verbrennungsraumes ist wegen der schweren Theilbarkeit und langsamen Verdampfung jenes Brennstoffes gröfser als die Fortpflanzungsgeschwindigkeit der Verbrennung, und da der Verbrennungsraum nicht beliebig erweitert werden kann, vielmehr in Ansehung der Nützlichkeit hoher Verdichtung der Verbrennungsluft und der vollkommenen Expansion, welche geringe Cylinderfüllungen erfordert, relativ klein sein mufs, so ergiebt sich hier jene besondere Schwierigkeit im Vergleich zur Verbrennung im freien Raum. Diese Schwierigkeit wird überwunden, indem zwei Staubstrahlen aus den diametral gegenüberliegenden Zerstäubern S S unmittelbar gegen einander treten gelassen werden, wobei die Energie des einen Staubstrahles die des anderen vernichtet und bei Z mehr oder minder Ruhe eintritt, in der der Staub am besten verbrennt. Es bildet sich ein Flammenbündel; der Form desselben entsprechend ist der Verbrennungsraum gestaltet, und es wird die zu erstrebende völlige Aufzehrung der Luft ohne nennswerthe Verrufsung der Wandungen nahezu erreicht. Es kann auch einem Staubstrahl ν ein durch Kanal w zugeführter Luftstrahl (Fig. 2) entgegentreten, was eine etwas abweichende Flammengestalt und dementsprechende Formgebung des Verbrennungsraumes bedingt.With this innovation, the main aim is to achieve the complete and faultless combustion of jets of dust from heavy crude oils, tar and liquid fuels in general in an engine that works like today's gas engines. The greatest difficulty here is offered by the small expansion of the combustion chamber, as a result of which the atomizing air (which, in order to properly break up the oil, must necessarily have a large outflow velocity) throws a more or less large part of the oil particles against the walls before it only separates slowly developing flame can be achieved. The mean speed of the dust jet inside the combustion chamber is greater than the rate of propagation of the combustion because of the difficulty in dividing and slow evaporation of that fuel, and since the combustion chamber cannot be expanded at will, rather in view of the usefulness of the high compression of the combustion air and the perfect expansion, which requires small cylinder fillings and must be relatively small, so there is that particular difficulty in comparison with combustion in free space. This difficulty is overcome in that two dust jets from the diametrically opposite atomizers SS are allowed to come directly against each other, the energy of one dust jet destroying that of the other and more or less calm occurs at Z , in which the dust burns best. A bundle of flames forms; the combustion chamber is designed in accordance with its shape, and the aspired total consumption of the air is almost achieved without any noteworthy damage to the walls. A jet of air supplied through channel w (FIG. 2) can also counteract a jet of dust ν , which causes a somewhat different flame shape and a corresponding shape of the combustion chamber.
Die Entzündung kann mittelst Flamme erfolgen, welche jedesmal im.Moment des Eintrittes der Staubstrahlen erzeugt wird, und zwar in der Weise, dafs ein dünner, langer Staubstrahl von leicht verdampfbarem Petroleum durch die vorher auf Glühhitze gebrachten Wandungen des Raumes f entzündet wird und, wie gezeichnet, den Staubstrahl trifft. Durch die Hitze dieser Zündflamme werden die Wandungen von f auf einem zündfähigen Hitzegrad erhalten.The ignition can take place by means of a flame, which is generated each time at the moment the dust jets enter, in such a way that a thin, long dust jet of easily evaporable petroleum is ignited through the walls of the room f which have previously been brought to glowing heat, and how drawn, hits the dust jet. Due to the heat of this pilot flame, the walls of f are kept at an ignitable degree of heat.
Die Erzeugung der Staubstrahlen geschieht in der gezeichneten inneren Stellung des Kolbens, in welcher die Verbrennungsluft zusammengeprefst ist.The generation of the dust jets takes place in the drawn inner position of the piston, in which the combustion air is compressed.
