Description

Einrichtung zum Kühlen der Zündkerzen von Brennkraftmaschinen Gegenstand der Erfindung ist eine Einrichtung zur Luftkühlung der Zündkerzen von Brennkraftmaschinen, vorzugsweise von Gasmaschinen. Die Zündkerzen erfordern eine Kühlung, damit die hohen Temperaturen dies Brennraumes nicht ihre frühzeitige Zerstörung zur Folge haben.Device for cooling the spark plugs of internal combustion engines Subject the invention is a device for air cooling the spark plugs of internal combustion engines, preferably from gas engines. The spark plugs require cooling so that the high temperatures of this combustion chamber do not result in their premature destruction to have.

Es wurde vorgeschlagen, die Zündkerzen einer Bnennkraftmaschine in einen kanalartigen Hohlraum einzuschließen, der von den Zylinderköpfen mitgebildet wird. In. diesen° Hohlraum wird die Verbrennungsluft durch einzelne Stutzen angesaugt, die gegen die Zündkerzen gerichtet sind. Eine Sammelleitun,g führt die Luft weiter den Zylindern zu. Die Einrichtung bewirkt nur dann eine gute Kühlung der Kerzen, wenn diese über ihre ganze Höhe aus der Oberfläche des Zylinderkopfes herausragen, da hauptsächlich nur der untere metallische Teil der Kerze zur Wärmeabgabe geeignet ist. Wegren der Abmessungen des Kühlwassermantels liegen aber die Zündkerzen, insbesondere bei größeren Maschinen, tief in einer Höhlung des Zylinderkopfes, so daß eine derart einfache Vorb.eiführung der Luft nicht möglich ist. Die bekannte Kühleinrichtung hat ferner den Nachteil, daß die Verbrennungsluft durch Wärmeaufnahme von seihen der Zündkerzen und der Hohlraumwandungen vor dem Eintritt in die Arbeitszylinder eine erhebliche Temperaturzunahme erfährt und das angesaugte Luftgewicht infolge der Wärmtedehnung entsprechend vermindert wird.It has been proposed to use the spark plugs of a rated engine in to include a channel-like cavity, which is formed by the cylinder heads will. In. The combustion air is sucked into this cavity through individual nozzles, directed against the spark plugs. A collecting line carries the air further to the cylinders. The device only ensures good cooling of the candles, if these protrude from the surface of the cylinder head over their entire height, since mainly only the lower metallic part of the candle is suitable for heat dissipation is. Because of the dimensions of the cooling water jacket, however, the spark plugs, in particular, lie in larger machines, deep in a cavity in the cylinder head, so that one of these simple preparation of the air is not possible. The well-known cooling device also has the disadvantage that the combustion air is due to the absorption of heat the spark plugs and the cavity walls before entering the working cylinder experiences a considerable increase in temperature and the air weight that is sucked in as a result the thermal expansion is reduced accordingly.

Gemäß der Erfindung werden diese Nachteile vermieden durch einzelne die Zündkerzen je für sich umschließende im Zylinderkopf liegende Höhlungen, die unmittelbar mit dem Raum vor dem Einlaßventil, z. B. dem Lufteinlaßventil, durch solche Querschnitte in Verbindung stehen, daß insgesamt nur ein Teil "der angesaugten Verbrennungsluft an den Zündkerzen vorbeigeleitet wird. Diese Luftmenge kann hinter dem Luftfilter vom Hauptluftstrom abgezweigt werden. Dier Einfachheit halber und in Anbetracht der Geringfügigkeit der Luftmenge kann man dagegen die Kühlluft auch unmittelbar von außen durch die Höhlungen ansaugen lassen. Die erfindungsgemäße Einrichtung, die zugleich das Niederschlagen von Kondensaten verhindert und dadurch die Kurzschlußgefahr beseitigt, ist in gleicher Weise bei Gasmaschinen und Vergasermaschinen anwendbar.According to the invention, these disadvantages are avoided by individual the spark plugs each for enclosing cavities in the cylinder head that immediately with the space in front of the inlet valve, e.g. B. the air inlet valve by such cross-sections are in connection that a total of only a part "of the sucked Combustion air is routed past the spark plugs. This amount of air can be behind can be branched off from the main air flow at the air filter. For the sake of simplicity, and In view of the insignificance of the amount of air, on the other hand, you can also use the cooling air let it suck in directly from the outside through the cavities. The inventive A device that also prevents condensation from precipitating and thereby eliminates the risk of short circuits, is in the same way with gas engines and carburetor machines applicable.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Abb. r ist ein teilweiser Längsschnitt nach I-1 der Abb.2 durch den Zylinderkopf einer Gasmaschine. Abb. 2 ist ein waagerechter Schnitt nach II-II der Abb. i.An exemplary embodiment of the invention is shown in the drawing. Fig. R is a partial longitudinal section along I-1 of the Fig.2 through the cylinder head of a gas engine. Fig. 2 is a horizontal section according to II-II of fig. i.
