Description
Gemischvorwärmer für Verbrennungskraftmaschinen. Die Erfindung bezieht sich auf einen Gemischvorwärmer für Verbrennungskraftmaschinen, :der dadurch neu und eigentümlich ist, daß das Gemisch der Reihe nachmehrere metallische Blöcke durchströmt, deren Kanalquerschnitte in der Strömungsrichtung abnehmen, und _daß zwischen Iden Blöcken Entspannungskammern angeordnet sind.Mixture preheaters for internal combustion engines. The invention relates on a mixture preheater for internal combustion engines: the new and it is peculiar that the mixture flows through several metallic blocks one after the other, whose channel cross-sections decrease in the direction of flow, and that between Iden Blocks expansion chambers are arranged.
In der Zeichnung ist ein Ausführungsbeispiel dargestellt.An exemplary embodiment is shown in the drawing.
Hauptsächlich besteht der Apparat aus dem Vergaser i und seiner Spritzdüse 2, über der .die Blöcke 3 und 4 angeordnet sind, zwischen welchen eine« Expansionskammer 5 liegt. Diese Blöcke besitzen Kanäle oder Düsen 6 von kleinem Durchmesser und liegen in einer Heizkammer 7, welche zwei Röhren 8 und 9 trägt. Ein drittes Rohr io liegt am Ausgange der Düsen 6. Ein Ventil i i im Vergaser regelt den Zutritt des Gases zum Motor.The apparatus mainly consists of the carburetor i and its spray nozzle 2, above the .the blocks 3 and 4 are arranged, between which an «expansion chamber 5 lies. These blocks have channels or nozzles 6 of small diameter and lie in a heating chamber 7 which carries two tubes 8 and 9. A third pipe is located at the outlet of the nozzles 6. A valve i i in the carburetor regulates the admission of the gas to the engine.
Die Wirkungsweise der Einrichtung ist folgende: Der Kohlenwasserstoff und die Luft treten unter :der Saugwirkung des Motorkolbens von dem Vergaser i und der Düse?, als nicht homogenes Gemisch in die Düsen 6 des Blockes 4. Die beträchtliche Geschwindigkeit, die molekularen Reibungen und die Zusammenziehungen, denen sie hierdurch unterworfen werden, bewirken durch eine innige Mischung des Kohlenwasserstoffes und der Luft ihre Atomisierung oder Zerstäubung.The device works as follows: The hydrocarbon and the air come under: the suction of the engine piston from the carburetor i and the nozzle ?, as a non-homogeneous mixture into the nozzles 6 of the block 4. The considerable Speed, the molecular frictions, and the contractions they cause are subjected to this effect through an intimate mixture of the hydrocarbon and air is atomized or atomized.
Das Gas kommt darauf in die Expansionskammer 5 und von :dort in eine Reihe von feinen Kanälen von noch kleinerem Durchmesser, nämlich im Block 3, wodurch die Zerstäubung vollendet wird. Darauf gelangt das Gemisch durch das Rohr io in :den Motor.The gas then comes into the expansion chamber 5 and from there into a Series of fine channels of even smaller diameter, namely in block 3, whereby the atomization is completed. The mixture then passes through the pipe io in :the engine.
Um die Vergasung zu erleichtern und die Kondensation des Kohlenwasserstoffes zu vermeiden, sind die Kanäle erwärmt, sei es etwa durch einen Umlauf des Kühlwassers oder aber vorzugsweise durch die Auspuffgase. Zu diesem Zweck ist die neue, durch die Blöcke 3 und 4 gebildete Vorrichtung in einer Heizkammer 7 untergebracht, welche die Röhren 8 und 9 für den Eintritt und Austritt der Heizflüssigkeit trägt, so daß die Blöcke 3 und 4 auf eine geeignete Temperatur gebracht werden. Die letzteren bilden infolge ihrer Masse und des schwachen Durchmessers der Kanäle gewissermaßen einen Wärmespeicher, .der die plötzlichen Temperaturänderungen .der Heizung vermeidet. Der schwache Durchmesser der Kanäle sichert eine innige Berührung des anzuwärmenden Gases mit der Heizquelle.To facilitate gasification and condensation of the hydrocarbon To avoid this, the channels are heated, for example by circulating the cooling water or preferably through the exhaust gases. To this end, the new one is through the blocks 3 and 4 formed device housed in a heating chamber 7, which the tubes 8 and 9 carries for the entry and exit of the heating fluid, so that the blocks 3 and 4 are brought to a suitable temperature. The latter form, as it were, due to their mass and the small diameter of the channels a heat storage. which avoids sudden temperature changes. of the heating. The small diameter of the channels ensures an intimate contact with the material to be heated Gas with the heating source.
Die Anordnung ist nur als Ausführungsbeispiel dargestellt. Man könnte beispielsweise die Zahl der Blöcke und der dazwischenliegenden Entspannungsräume vermehren, ohne die Erfindungsidee zu verlassen.The arrangement is shown only as an exemplary embodiment. One could for example the number of blocks and the relaxation spaces in between multiply without leaving the inventive idea.
