Description

Brennkraftmasehine mit Vorkammer Die Erfindung betrifft eine Brennkraftmaschine mit einer in einen gekühlten Zylinderdeckel eingesetzten Vorkammer und besteht darin, daß der eingesetzte Vorkammerkörper durch eine an seinem inneren Ende angreifende und von dort durch den Kühlraum und die äußere Deckelwand hindurch nach außen geführte Druckhülse, deren Mantel Aussparungen aufweist, an die innere Deckelwand gepreßt wird. Dadurch soll dem Vorkamnierkörper nicht nur eine freie Ausdehnung in der Längsrichtung ermöglicht, sondern er soll auch in jede beliebige Lage gedreht werden können.Internal combustion engine with prechamber The invention relates to an internal combustion engine with an antechamber inserted into a cooled cylinder cover and consists in that the inserted prechamber body by an engaging at its inner end and passed from there through the cooling space and the outer cover wall to the outside Pressure sleeve, the jacket of which has recesses, pressed against the inner cover wall will. This should not only allow the prechamber body to expand freely in the longitudinal direction allows, but it should also be able to be rotated into any position.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist auf der Zeichnung zur Darstellung gebracht.An embodiment of the subject matter of the invention is shown in the drawing brought to the display.

Fig. i ist ein teilweiser Schnitt nach der Linie 1-I der Fig. 2 und Fig. 2 ein Schnitt nach der Vinie 11-1I der Fig. i.Fig. I is a partial section on the line 1-I of Figs FIG. 2 is a section along the line 11-1I of FIG.

<z ist die innere. b die äußere Wand des Kühlmantels, c der Kühlraum, d die Vorkammer und e der gekühlte Vorkammereinsatz des nicht weiter gezeichneten, gekühlten Zylinderdeckels einer Vorkammerbrennkraftmaschine, deren Verbrennungsraum mit f bezeichnet ist. Der Brennstoff wird in üblicher Weise durch die von der Nadel g gesteuerte Düse lt. in die Vorkammer eingespritzt, dort zum Teil verbrannt und dann von dem dabei sich ausdehnenden gasförmigen Kammerinhalt durch die öffnungen i in brennendem Zustand in denVerbrennungsraum geschleudert. Der Vorkammereinsatz wird durch eine Anpreßvorrichtung, bestehend aus den Schrauben k, den Muttern l und der Brille an., dichtend an die innere Wand des Zylinderdeckels angepreßt. Die Brille ist dabei, anstatt wie bisher auf dem obern Ende des Vorkammereinsatzes aufzusitzen, mit einem am unteren, dem Verbrennungsraum zugekehrten Ende angreifenden, rohrförmigen Fortsatz ia versehen, der es dem im Betrieb hoch sich erhitzenden Einsatz gestattet, sich entsprechend dem Erhitzungsgrad frei auszudehnen. In dem Fortsatz sind Fenster o derart ausgespart, daß das Kühlwasser des Zylinderdek-_ kels ungehinderten Zutritt zu dem Vorkaminereinsatz hat.<z is the inner one. b the outer wall of the cooling jacket, c the cooling space, d the prechamber and e the cooled prechamber insert of the not further drawn, cooled cylinder cover of a prechamber internal combustion engine, the combustion space of which is denoted by f. The fuel is in lt customary manner by g controlled by the needle nozzle. Injected into the antechamber, where it is burnt part and then flung from the thereby expanding gaseous chamber contents through the openings i in burning state in denVerbrennungsraum. The antechamber insert is pressed against the inner wall of the cylinder cover in a sealing manner by a pressing device consisting of the screws k, the nuts l and the glasses an. Instead of sitting on the upper end of the antechamber insert as before, the glasses are provided with a tubular extension generally engaging the lower end facing the combustion chamber, which allows the insert, which heats up during operation, to expand freely according to the degree of heating. Windows o are recessed in the extension in such a way that the cooling water of the cylinder cover has unimpeded access to the pre-fireplace insert.
