Description
Vergaser für Verbrennungskraftmaschinen. Die Erfindung will die Aufgabe lösen, die Vergasung des flüssigen Brennstoffes in einer Atmosphäre toter verbrannter Gase, vor allem in den Abgasen der Verbrennungskraftmascbinen stattfinden zu lassen. Hierbei soll aber die Zuführung des Brennstoffes wie bisher durch eine Zerstäubungsdüse und durch die Saugwirkung der Maschine erfolgen. Da die Abgase aber bekanntlich noch eine erhebliche Spannung besitzen, so darf eine unmittelbare Verbindung der Abgasleitung mit dem unter der Saugwirkung der Maschine stehenden Vergaser nicht angeordnet sein.Carburettors for internal combustion engines. The invention aims to do the job solve the gasification of liquid fuel in an atmosphere of dead burned Gases, especially in the exhaust gases from the internal combustion engines. In this case, however, the fuel should be fed through an atomizing nozzle as before and by the suction of the machine. Since the exhaust gases are known still have a considerable tension, a direct connection of the Exhaust pipe with the carburettor, which is under the suction effect of the machine, does not be arranged.
Die Erfindung löst nun diese Aufgabe dadurch, daß der Vergaser mit der Abgasleitung durch eine Zweigleitung verbunden ist, welche sowohl gegen die Atmosphäre wie gegen den Vergaser geöffnet ist, wobei jedoch diese Zweigleitung nach beiden Seiten durch drosselnde Hilfsmittel, wie z. B. engmaschige Siebe, durchlöcherte Bleche u. dgl., zum Teil abgeschlossen ist, die ein vollkommen hemmungsloses Austreten der Abgase aus der Zweigleitung nach beiden Seiten verhindern. Vielmehr wird hierdurch erreicht, daB diese Zweigleitung dauernd mit Abgasen gefüllt ist, die nicht mehr die volle Spannung der frisch austretenden Abgase haben, sondern nur noch einen Druck aufweisen, der den atmosphärischen Druck um ein Geringes überschreitet.The invention now solves this problem in that the carburetor with the exhaust pipe is connected by a branch pipe, which both against the Atmosphere is open as against the carburetor, but this branch line on both sides by throttling aids, such as. B. close-meshed sieves, perforated Sheet metal, etc., is partially completed, which allows a completely unrestrained leakage prevent the exhaust gases from the branch pipe on both sides. Rather, it will achieves that this branch line is permanently filled with exhaust gases that are no longer have the full tension of the freshly emerging exhaust gases, but only one Have pressure that slightly exceeds atmospheric pressure.
Dadurch wird einmal das Eindringen von Luft in die Zweigleitung wirksam verhindert, andererseits aber kann der Druck nicht nach dem Vergaser zu wirken, weil die Drosselung durch das Sieb o. dgl. nach dem Vergaser zu genügt, um diesen geringfügigen Überdruck für den Vergaser unschädlich zu machen. Somit kann der Vergaser, wie allgemein üblich, unter der Saugwirkung der Maschine stehen, so daB das Einspritzen des Brennstoffes bei jedem Saughub in der bisherigen Weise erfolgt. Gleichzeitig wird aber auch bei jedem Saughub ein Teil der Abgase in den Vergaser angesaugt, so daB der Brennstoff in üblicher Weise, nicht in Luft, sondern in einer Atmosphäre von Abgasen vergast wird.As a result, the penetration of air into the branch pipe becomes effective prevented, on the other hand, however, the pressure cannot act on the carburetor, because the throttling through the sieve o make slight overpressure for the carburetor harmless. Thus, the carburetor, As is generally the case, stand under the suction of the machine, so that the injection of the fuel takes place in the previous manner with each suction stroke. Simultaneously however, some of the exhaust gases are sucked into the carburettor with every suction stroke, so that the fuel in the usual way, not in air, but in an atmosphere is gasified by exhaust gases.
Die spätere Mischung dieses Brennstoffabgasgemisches mit der Verbrennungsluft erfolgt dann in beliebiger Weise.The later mixing of this fuel exhaust gas mixture with the combustion air then takes place in any way.
Bei der in der Zeichnung veranschaulichten Ausführungsform der Erfindung besteht der Vergaser aus einer senkrecht stehenden länglichen Kammer a, die von einem Mantel a1 umgeben ist, in welchen die Abgase durch den oberen Stutzen a2 eintreten und ihn durch den unteren Stutzen a3 verlassen. Die Zuführung des Brennstoffes in die Vergaserkammer a erfolgt durch die bei c angedeutete Einspritzdüse oder durch einen Kanal. Auf dem oberen Hals der Kammer a und des Mantels a1 sind übereinander Kappen e und f aus Sieben, durchlöcherten Blechen usw. aufgesetzt. Der von diesen Kappen eingeschlossene Raum steht durch eine Einschnürung mit dem Mantelinnern in Verbindung, so daß diese Einrichtung eine Zweigleitung für die Abgase darstellt, ,durch welche ein Teil der Abgase entweichen kann. Die obere Öffnung d der Vergaserkammer ist noch mit einem Filtersieb g versehen, um die in die Vergaserkammer gelangenden Abgase vor ihrem Eintritt zu reinigen.In the embodiment of the invention illustrated in the drawing the carburetor consists of a vertical elongated chamber a, which is from a jacket a1 is surrounded, in which the exhaust gases enter through the upper nozzle a2 and leave it through the lower nozzle a3. The supply of the fuel in the carburetor chamber a takes place through the injection nozzle indicated at c or through a channel. On the upper neck of the chamber a and the jacket a1 are one above the other Caps e and f made of sieves, perforated metal sheets, etc. put on. The from this The space enclosed by the caps is connected to the inside of the jacket by a constriction Connection so that this device represents a branch line for the exhaust gases, through which some of the exhaust gases can escape. The upper opening d of the carburetor chamber is also provided with a filter sieve g to prevent the gas entering the carburetor chamber To clean exhaust gases before they enter.
Das Innere der Vergaserkammer a steht durch den Stutzen b in irgendeiner Weise mit der Verbrennungskraftmaschine in Verbindung, so kann z. B., wie die Zeichnung zeigt, der Stutzen b an das bekannte Luftzuführungsrohr A angeschlossen sein, durch welches sich die Maschine die erforderliche Verbrennungsluft in der durch die Drosselklappe i bestimmten Menge ansaugt.The interior of the carburetor chamber a is through the port b in any Way with the internal combustion engine in connection, so can, for. B., like the drawing shows the nozzle b connected to the known air supply pipe A through which the machine has the required combustion air in through the throttle valve i sucked in certain amount.
Die Wirkungsweise des Vergasers ist die folgende Durch den Stutzen a2 treten die Abgase in den Mantelraum des Vergasers, den sie zum größten Teil durch den Stutzen a3 verlassen. Ein Teil der Abgase geht durch die Einschnü= rang, die übrigens bedeutend enger wie dargestellt sein kann, in die von den Kappen e und f gebildete Zweigleitung und entweicht zum Teil durch die Kappe f, so daß der Raum zwischen den Kappen dauernd durch Abgase mit ganz geringem Überdruck (hervorgerufen durch die Drosselwirkung der Kappen) erfüllt ist. Wirkt nun ein' Saughub der Maschine durch den Stutzen b auf die Vergaserkammer a, so wird aus der Düse c Brennstoff eingeführt, gleichzeitig aber auch durch die Kappen e und g ein Teil der Abgase in die Vergaserkammer a gesaugt; diese ist also dauernd mit Abgasen von atmosphärischem Druck erfüllt, und die Vergasung des Brennstoffes erfolgt in einer Atmosphäre von Abgasen.The mode of operation of the carburetor is as follows. The exhaust gases enter the casing space of the carburetor through the connection a2, which they leave for the most part through the connection a3. Part of the exhaust gas goes through the constriction, which can be much narrower as shown, into the branch line formed by the caps e and f, and partly escapes through the cap f, so that the space between the caps is constantly carried by the exhaust gases very slight overpressure (caused by the throttling effect of the caps) is fulfilled. If a suction stroke of the machine acts through the nozzle b on the carburetor chamber a, fuel is introduced from the nozzle c, but at the same time some of the exhaust gases are sucked into the carburetor chamber a through the caps e and g; this is therefore constantly filled with exhaust gases of atmospheric pressure, and the gasification of the fuel takes place in an atmosphere of exhaust gases.
Falls gewünscht, kann man durch Düse c mit dem Brennstoff zusammen etwas Luft einführen; soll dies nicht. geschehen, so kann die Einspritzdüse in die Öffnung d der Vergaserkammer verlegt werden, so daß die Abgase den Brennstoff -in die Kammer a mitnehmen.If desired, you can come together with the fuel through nozzle c introduce some air; shouldn't this. happen, so the injector into the Opening d of the carburetor chamber can be relocated, so that the exhaust gases the fuel -in take the chamber a with you.
Der Vergaser kann in jeder beliebigen Weise mit der Maschine verbunden werden; der hier dargestellte Anschluß an die Verbrennungsluftleitung ist lediglich als eine der vielen möglichen Anordnungen anzusehen.The carburetor can be connected to the machine in any way will; the connection to the combustion air line shown here is only to be regarded as one of the many possible arrangements.
