Description

Die Erfindung bezieht sich auf einen Zylinderkopf für luftgekühlte Brennkraftmaschinen mit einer Brennkammer in der Anblasrichtung, insbesondere für Kraftfahrzeuge.The invention relates to a cylinder head for air-cooled Internal combustion engines with a combustion chamber in the blowing direction, especially for Motor vehicles.

Bei den bekannten Ausführungen dieser Art ist meist die Einspritzdüse über der Glühkerze angeordnet, d. h. die Einspritzdüse und die Glühkerze liegen in einer senkrechten durch die Zylinderkopfachse gelegten Ebene. Bei luftgekühlten Brennkraftmaschinen entsteht dadurch der Nachteil, daß der durch den Zylinderkopf zwischen den Ventilführungen streichende Kühlluftstrom beim Eintritt in den Zylinderkopf von kleinem Querschnitt wird, so daß nur sehr wenig Kühlluft aus dem mittleren Kühlluftkanal strömt, wodurch der Zylinderkopf unzureichend gekühlt wird.In the known designs of this type, it is usually the injection nozzle arranged over the glow plug, d. H. the injector and the glow plug are lying in a vertical plane laid through the cylinder head axis. With air-cooled Internal combustion engines have the disadvantage that the cylinder head Cooling air flow sweeping between the valve guides as it enters the cylinder head of small cross-section, so that very little cooling air from the central cooling air duct flows, whereby the cylinder head is insufficiently cooled.

Um diesem Übelstand zu begegnen, werden gemäß der Erfindung die Einspritzdüse und die Glühkerze in einer Ebene angeordnet, die im wesentlichen senkrecht zur Zylinderkopfachse verläuft. Damit wird ein sehr großer Eintrittsquerschnitt für die Kühlluft geschaffen und können auch zahlreiche Kühlrippen angeordnet werden.In order to counteract this drawback, the injection nozzle according to the invention and the glow plug arranged in a plane which is substantially perpendicular to the cylinder head axis runs. This creates a very large inlet cross-section for the cooling air and numerous cooling fins can also be arranged.

In den Zeichnungen ist eine Ausführungsform der Erfindung veranschaulicht. Es zeigt Fig. i einen teilweisen Längsschnitt durch einen luftgekühlten Zylinderkopf mit Brennkammer nach der Erfindung, Fig.2 eine Vorderansicht des Zylinderkopfes nach Fig. i, wobei Einspritzdüse und Zündkerze abgenommen sind, und Fig. 3 einen Schnitt nach der Linie III-III der Fig. i.An embodiment of the invention is illustrated in the drawings. FIG. 1 shows a partial longitudinal section through an air-cooled cylinder head with a combustion chamber according to the invention, Figure 2 is a front view of the cylinder head according to FIG. i, with the injection nozzle and spark plug removed, and FIG. 3 shows a Section along the line III-III of Fig. I.

Der Zylinderkopf besteht aus dem Grundkörper i und der Schale 2, auf welche die Haube 3 aufgesetzt ist. Im Grundkörper ist die Brennkammer 4 eingegossen oder auf andere Weise im Zylinderkopf befestigt. In die Brennkammer ragt die Einspritzdüse 5. Die Einspritzdüse ist in einer Ebene W-W angeordnet, die senkrecht zur Achse A-A des Zylinderkopfes liegt. Es ist dies bei lotrechten Zylindern eine waagerechte Ebene. In derselben Ebene W-W seitlich von der Einspritzdüse und ebenfalls in die Brennkammer mündend ist die Glühkerze 6 in einer Bohrung 7 der Brennkammer angeordnet.The cylinder head consists of the base body i and the shell 2 on which the hood 3 is placed. The combustion chamber 4 is cast in the base body or fastened in some other way in the cylinder head. The injection nozzle 5 protrudes into the combustion chamber. The injection nozzle is arranged in a plane WW which is perpendicular to the axis AA of the cylinder head. In the case of vertical cylinders, this is a horizontal plane. In the same plane WW to the side of the injection nozzle and also opening into the combustion chamber, the glow plug 6 is arranged in a bore 7 of the combustion chamber.

Die Luft zur Kühlung des Zylinderkopfes, welche in der Anbläsrichtung R gegen den Zylinderkopf strömt, findet einen Kanal großen Querschnittes zwischen der Schale des Zylinderkopfes und der Einspritzdüse, so daß eine verhältnismäßig große Luftmenge durch den mittleren Kanal 8 in den Zylinderkopf strömt. Zweckmäßig ist dieser Kanal durch vorzugsweise senkrechte Rippen 9 unterteilt. Außerdem strömt Luft seitlich durch den Zylinderkopf, wodurch sich eine sehr gute Kühlung desselben ergibt, wobei auch genügend Platz zur Anbringung der Zylinderkopfschrauben io bleibt. Wie aus Fig. 2 hervorgeht, verengt sich der Kanal 8 im Bereich des Einlasses i i und des Auslasses .i2, wodurch eine Beschleunigung der durchströmenden Luft erreicht wird.The air for cooling the cylinder head, which in the blowing direction R flows against the cylinder head, finds a channel with a large cross-section between the shell of the cylinder head and the injector, so that a relatively large amount of air flows through the central channel 8 into the cylinder head. Appropriate this channel is divided by preferably vertical ribs 9. It also flows Air laterally through the cylinder head, which means that it is very well cooled results, whereby there is also enough space to attach the cylinder head screws. As can be seen from FIG. 2, the channel 8 narrows in the region of the inlet i i and the outlet .i2, whereby an acceleration of the air flowing through is achieved will.

Die Erfindung ist für alle Arten von Brennkammern anwendbar. Auch ist es ohne Bedeutung, in welcher Art die Einspritzdüse und die Glühkerze im Zylindei"kopf befestigt sind. Ebenso kann der Grundkörper des Zylinderkopfes mit der Schale aus einem Stück gegossen sein.The invention is applicable to all types of combustion chambers. Even it does not matter in which way the injection nozzle and the glow plug in the cylinder head are attached. Likewise, the base body of the cylinder head can be made with the shell be cast in one piece.
