Description

Spritzvergaser. Die Erfindung betrifft einen Vergaser für Verbrennungsmotoren, bei dem eine das Spritzrohr umgebende doppeltrichterförmige Luftdüse in Verbindung mit der Drosselklappe bewegt wird und dabei in den Mischraum mündende Zusatzluftöffnungen steuert. Das Wesen der Erfindung liegt darin, daß der Lufttrichter mehrere Reihen von im Ouerschnitt zunehmenden Kanälen besitzt, die nacheinander mit den Zusatzluftöffnungen im Vergasergehäuse in Verbindung treten. Dadurch wird es möglich, neben den üblichen leichten Brennstoffen, wie Benzin, Benzol usw., auch Stoffe schwerster Art, wie vorzugsweise Petroleum, zu vergasen, und zwar nicht nur bei großen Motoren, wo dies bisher schon möglich war, sondern auch bei kleinsten Maschinen für Motorboote, Automobile o. dgl. Der neue Vergaser läßt sich für jeden Brennstoff anwenden, ohne daß ein Umbau dabei nötig wäre.Injection carburetor. The invention relates to a carburetor for internal combustion engines, in which a double funnel-shaped air nozzle surrounding the spray tube in connection is moved with the throttle valve and additional air openings opening into the mixing chamber controls. The essence of the invention is that the air funnel has several rows of channels increasing in cross section, one after the other with the additional air openings connect in the carburetor housing. This makes it possible besides the usual light fuels, such as gasoline, benzene, etc., also the heaviest substances, such as preferably petroleum, to gasify, and not just on large engines where this is was already possible up to now, but also for the smallest machines for motor boats and automobiles o. The like. The new carburetor can be used for any fuel without a Conversion would be necessary.

Der Erfindungsgegenstand ist auf der Zeichnung in einem Ausführungsbeispiel, und zwar in Abb. z im senkrechten Längsschnitt, in Abb. 2 teilweise im Querschnitt und in Abb. 3 im Querschnitt nach Linie a-a dargestellt.The subject of the invention is shown on the drawing in an exemplary embodiment, namely in Fig. z in vertical longitudinal section, in Fig. 2 partially in cross section and shown in Fig. 3 in cross section along line a-a.

Der Vergaser besitzt den üblichen Schwimmerbehälter a mit Ringschwimmer b, der in bekannter Weise auf das Brennstoffventil c einwirkt. Die Spritzöffnung der Spritzdüse d wird durch die Nadele geregelt. Das Spritzrohr wird durch einen Doppeltrichter (Luftdüse) f umgeben und ist in der Längsrichtung verschiebbar. Dieser Doppeltrichter besitzt eine Reihe von Kanälen g, welche vorzugsweise schräg zum Saugrohr liegen, und deren Querschnitte zunehmen. Diese kommen bei einer bestimmten Stellung des Trichters mit Durchbrechungen h der Vergaserwand in Verbindung. Ein Kanal i umschließt die Durchbrechungen. Der Trichter f steht in passender Weise mit der Drosselklappek in Zwangsverbindung. Zwischen Klappe k und Vergaserdurchgang ist ein Vorwärmer l (Abb. i und 2) vorgesehen, der durch die Auspuffgase beheizt wird.The carburetor has the usual float tank a with a ring float b, which acts in a known manner on the fuel valve c. The spray opening of the spray nozzle d is regulated by the needle. The spray tube is surrounded by a double funnel (air nozzle) f and can be moved in the longitudinal direction. This double funnel has a number of channels g, which are preferably inclined to the suction pipe, and whose cross-sections increase. At a certain position of the funnel, these come into contact with openings h in the carburetor wall. A channel i encloses the openings. The funnel f is in a suitable manner in positive connection with the throttle valve. A preheater l (Fig. I and 2), which is heated by the exhaust gases, is provided between flap k and the carburetor passage.

Der Vergaser arbeitet in folgender Weise: Wird durch Offnen der Drosselklappe k der Durchlaß nach dem Motor vergrößert, so hebt sich beim Bewegen der Klappe gleichzeitig der Trichter f. Die Kanäle g kommen dabei nach und nach mit den Durchbrechungen hin Verbindung, wodurch dem bereits zerstäubten Brennstoff Frischluft in genau bemessener Menge zugeführt wird, die sich innig mit dem Brennstoff vermischt, ohne daß dabei im Bereiche der Düse die Sauggeschwindigkeit erhöht wird. Durch diese Anordnung wird somit ein Vergaser geschaffen, dessen Brennstoffzufuhr in seiner Menge, durch die Nadel e einmal eingestellt, dauernd konstant bleibt.The carburetor works in the following way: Is made by opening the throttle k the passage after the motor increases, so when the flap is moved it is raised at the same time the funnel f. The channels g gradually come with the openings towards connection, whereby the already atomized fuel fresh air in precisely measured Amount is supplied that is intimately mixed with the fuel without doing so the suction speed is increased in the area of the nozzle. Through this arrangement a carburetor is thus created, the fuel supply in its quantity through the needle e once set, remains constant over time.

Das Anlassen des Motors geschieht mittels eines leichten Brennstoffes, wie Benzin. Ist der Vorwärmer Z genügend durch die Auspuffgase erhitzt, so wird auf schweren Brennstoff umgeschaltet. Dieser zerstäubt in gleicher Weise wie der leichte Brennstoff. Er wird aber nach dem Zerstäuben im Vorwärmer vollkommen verdampft und leicht zündbar gemacht.The engine is started by means of a light fuel, like gasoline. If the preheater Z is sufficiently heated by the exhaust gases, it is switched to heavy fuel. This atomizes in the same way as the light fuel. However, it is completely evaporated in the preheater after atomization and made easily ignitable.

Der Vorwärmer ist leicht herausnehmbar angeordnet, damit er von Zeit zu Zeit gereinigt werden kann.The preheater is easily removable to keep it from time can be cleaned at time.
