Description
Einrichtung zum- Vorwärmen des Verbrennungsgemisches von Verbrennungsmotoren - mit Hilfe der Auspuffgase: Die Erfindung betrifft eine Einrichtung zum Vorwärmen des Verbrennungsgemisches von Verbrennungsmotoren mit Hilfe der Auspuffgase, zum Zwecke, lediglich für die Ingangsetzung des Motors leicht entzündlichenBrennstoff zu benötigen. -Erfindungsgemäß ist die Einrichtung so getroffen, daß das Verbrennungsgemisch zwei l#Zammern durchzieht, wobei es in der einen 1`ammer von den Auspuffgasen von außen nach innen und in der anderen Kammer von innen nach außen erhitzt wird. Durch diese doppelte Wärmeübertragung von außen nach innen und umgekehrt wird das Verbrennungsgemisch durch und durch erwärmt, so daß auch Schwerbrennstoff vollständig verdampft wird, während bei den bisherigen Vorwärmeeinrichtungen die Wärmeübertragung nur in einem Sinne erfolgt, und daher keine derart gute Ausnutzung der Hitze der Auspuffgase bzw. keine solch starke Vorwärmung des Verbrennungsgemisches erzielt wird.Device for preheating the combustion mixture of internal combustion engines - With the help of the exhaust gases: The invention relates to a device for preheating the combustion mixture of internal combustion engines with the help of the exhaust gases, for Purposes, only for starting the engine highly flammable fuel to need. According to the invention, the device is made so that the combustion mixture two l # chambers runs through, whereby there is in one 1`ammer of the exhaust gases from is heated from the outside to the inside and in the other chamber from the inside to the outside. By these double heat transfer from outside to inside and vice versa the combustion mixture is heated through and through, so that also heavy fuel is completely evaporated, while the previous preheating devices Heat transfer takes place in only one sense, and therefore not such good utilization the heat of the exhaust gases or no such strong preheating of the combustion mixture is achieved.
Auf der Zeichnung ist als Ausführungsheispiel des Erfindungsgegenstandes ein vierzylindriger Verbrennungsmotor dargestellt.In the drawing is an exemplary embodiment of the subject matter of the invention a four-cylinder internal combustion engine is shown.
Abb. i ist ein Aufriß, Abb. 2 ein Grundriß teilweise im Schnitt. Es bezeichnet i die vier ZN'llIider des Motors, 2 eine denselben gemeinsame Abgaskammer, welche durch ein Rohr 3 mit der Abgasleitungq. verbunden ist. 5 ist ein in der Kammer 2 befindliches Rohr, «-elches mit sog. Gallowayrohren versehen und an 'die zur Zuführung des Brermstoffes dienende Zuleitung 6 angeschlossen ist, in welche ein Vergaser 7 eingeschaltet ist. Die Leitung 6 kann durch entsprechende Einstellung eines Hahnes entweder von einem leicht entzündlichen Brennstoff, z. B. Benzin, enthaltenden Behälter aus gespeist werden oder von einem schwer entzündlichen Brennstoff, z. B. Petroleum, enthaltenden Behälter aus.Fig. I is an elevation and Fig. 2 is a plan view partly in section. It i denotes the four ZN'llIider of the engine, 2 a common exhaust chamber, which through a pipe 3 with the exhaust pipe q. connected is. 5 is one in the chamber 2 located pipe, "-elches provided with so-called Galloway pipes and attached to the feed the fuel serving feed line 6 is connected, in which a carburetor 7 is switched on. The line 6 can be adjusted by setting a tap either from a highly flammable fuel, e.g. B. gasoline, containing container fed from or from a fuel that is difficult to ignite, e.g. B. Petroleum, containing container.
An das Rohr 5 ist andern Endes ein schräg abwärts verlaufendes Rohr i i angeschlossen, las in ein horizontales Rohr i2 übergeht, «-elches durch zwei Stutzen 13 mit einer Kammer 1d. verbunden ist. Die Kammer 1d. dient zur Speisung der Nlotorzvlinder i ; sie ist von der Abgasleitung .I durchsetzt.At the other end of the tube 5 is connected a downward sloping tube ii, which merges into a horizontal tube i2, "-elches through two nozzles 13 with a chamber 1d. connected is. Chamber 1d. serves to supply the motor cylinder i; it is penetrated by the exhaust pipe .I.
Soll der Motor in Tätigkeit treten, dann speist man denselben vorerst mit leicht entzündlichem Brennstoff, der seinen Weg durch die Teile 6, 7, 8, 5, 1i, 12, 13 und 14 nimmt, utn dann in die Zvlinder einzutreten. Ist der Motor in Gang gesetzt und das Rohr 5 von den aus den Motorzylindern entweichenden Ahgasen erwärmt worden, dann schaltet man, beispielsweise 3 bis 4 Minuten nach dem Anlassen des Motors, den erwähnten Hahn um, zwecks Speisung des Motors mit schwer entzündlichem Brennstoff. Aus dem Vergaser 7 gelangt das Verbrennungsgemisch in das erhitr_te Rohr 5 und wird nun im Bereich der Abgaskammer 2 durch die Auspuffgase von außen nach innen erhitzt. Das Verbrennungsgemisch tritt dann in das Rohr i i über, wo demselben notwendigenfalls durch eine in das Rohr i i ragende Rohrleitung 15 mit durchlochtem Mantel Luft zugesetzt werden kann; das Lufteinlaßrohr 15 wird seinerseits durch das aus dem Rohr 5 kommende Verbrennungsgemisch erwärmt, so daß eingelassene Zusatzluft ebenfalls vorgewärmt wird. Durch das Rohr i2 und die Stutzen 13 nimmt das '\'erbrennungsgemisch -alsdann seinen Weg zu der von der Abgasleitung 4 durchsetzten Kammer 1d., wo es zum zweiten Male erhitzt wird, dieses Mal von innen nach außen. Daraufhin gelangt das nun durch und durch erwärmte und verdampfte Verbrennungsgemisch in die Zylinder i, um hier unter Arbeitsleistung zu verbrennen.If the engine is to start operating, it is first fed with highly flammable fuel, which takes its way through parts 6, 7, 8, 5, 1i, 1, 2, 13 and 14, then to enter the cylinder. Once the engine has started and the pipe 5 has been heated by the gases escaping from the engine cylinders, the above-mentioned tap is switched over, for example 3 to 4 minutes after the engine has been started, in order to supply the engine with fuel that is difficult to ignite. The combustion mixture passes from the carburetor 7 into the heated pipe 5 and is now heated in the area of the exhaust gas chamber 2 by the exhaust gases from the outside to the inside. The combustion mixture then enters the pipe ii about where the same can, if necessary, be added by a ii projecting into the tube conduit 1 with 5 durchlochtem outer air; the air inlet pipe 15 is in turn heated by the combustion mixture coming from the pipe 5, so that additional air admitted is also preheated. The '\' mixture of burns then takes its way through the pipe i2 and the connecting piece 13 to the chamber 1d. The combustion mixture, which has now been thoroughly heated and vaporized, then reaches the cylinder i, where it burns while performing work.
