Description
Brenner für kompressorlose Vorkammer- oder Luftspeicher-Dieselmotoren Es ist bekannt, bei Vorkammer-Dieselmotoren im Hals der -Vorkammer einen luftisolierten Einsatz anzuordnen, um den an dieser Stelle besonders lebhaften Wärmeübergang an die Deckelwandungen zu vermindern. Der Isolierraum dieses Einsatzes steht weder mit der Vorkammer noch mit dem Hauptarbeitsraum in Verbindung, sondern ist nach beiden Seiten hin dicht abgeschlossen und mit stagnierender, heißer Luft erfüllt.Burner for compressorless pre-chamber or air storage diesel engines It is known to have an air-insulated in the throat of the pre-chamber diesel engines in the throat of the pre-chamber Use to arrange the particularly lively heat transfer at this point to reduce the cover walls. The isolation room of this insert is neither with the antechamber still in connection with the main work space, but is after sealed on both sides and filled with stagnant, hot air.
Es ist auch schon vorgeschlagen worden, einen Einsatz im Vorkammerhals vorzusehen, bei dem der Ringspalt mit dem Vorkammerraum verbunden ist, indem ein oberer trichterförmiger Teil des Einsatzes außen gegen die gekühlte Zylinderwand durch einen von heißen Gasen erfüllten Spalt isoliert ist, während sein innerer, die Kammerwandungen enthaltender Teil in leitender Verbindung mit der gekühlten Zylinderwand steht, so daß der trichterförmige Teil des Einsatzes heißer als der innere Teil sein wird.It has also been proposed to use it in the atrial neck to be provided in which the annular gap is connected to the antechamber space by a Upper funnel-shaped part of the insert on the outside against the cooled cylinder wall is insulated by a gap filled with hot gases, while its inner, the part containing the chamber walls in conductive connection with the cooled one Cylinder wall stands so that the funnel-shaped part of the insert is hotter than the inner part will be.
Nach der Erfindung erhält der Einsatz, welcher sich in der Einschnürung der Vorkammer oder eines Luftspeichers von kompressorlosen Dieselmotoren befindet, an dem Ende nach dem Hauptarbeitsraum zu einen an die gekühlten Wandungen dauernd sich anlegenden Bund, welcher Nuten oder Löcher enthält, die den Ringraum um den Einsatz mit dem Hauptarbeitsraum verbinden. Der Einsatz ist. an seinem äußeren Ende gehalten und nach dem Vorkammer- oder Speicherraum zu dicht eingesetzt. Durch den am inneren Ende befindlichen Bund kann die Wärme ungehindert aus dem Boden an die gekühlte Wandung abströmen, während der Mantel von den aus dem Hauptarbeitsraum eindringenden Gasen schnell angeheizt wird.According to the invention, the insert that is located in the constriction receives the antechamber or an air reservoir of compressorless diesel engines, at the end after the main work room to one on the cooled walls applied collar, which contains grooves or holes that form the annulus around the Connect the insert to the main work area. The stake is. at its outer end held and inserted too tightly after the antechamber or storage space. Through the located at the inner end of the collar, the heat can unhindered from the bottom to the flow off cooled wall, while the jacket from the from the main work room penetrating gases is heated up quickly.
Eine Ausführungsform des Erfindungsgegenstandes ist in der Zeichnung beispielsweise dargestellt. Es zeigen Abb. I einen Schnitt durch den Zylinderkopf einer stehenden Vorkammer-Dieselmaschine und Abb. z den Einsatz von unten gesehen.An embodiment of the subject matter of the invention is shown in the drawing for example shown. Fig. I shows a section through the cylinder head a standing pre-chamber diesel engine and Fig. z the use seen from below.
Der Einsatzkörper a ist in den Vorkammerhals b des Zylinderkopfes c von oben her eingesetzt; er ist z. B. durch das Gewinde d am oberen Ende befestigt. Er besitzt am unteren, dem Verbrennungsraum zugekehrten Erde einen mit Bohrungen oder sonstigen öffnungen oder Nuten e versehenen Bund f, welcher sich an die gekühlten Wandungen des Vorkämmerhalses anlegt. Der Einsatz hat eine trichterförmige Gestalt und ist von einem Ringraum g umgeben sowie mit einer Bohrung h versehen; er kann aber ebensogut mit mehreren Bohrungen h versehen und zylindrisch ausgebildet sein. Eine solche Ausführungsform zeigen- die Abb. 3 und q.. Die Vorkammer selbst ist mit i und das Einspritzventil mit k bezeichnet.The insert body a is inserted into the antechamber neck b of the cylinder head c from above; he is z. B. fastened by the thread d at the upper end. On the lower ground facing the combustion chamber, it has a collar f provided with bores or other openings or grooves e , which rests against the cooled walls of the antechamber neck. The insert has a funnel-shaped shape and is surrounded by an annular space g and provided with a bore h; but it can just as well be provided with a plurality of bores h and be cylindrical. Such an embodiment is shown in FIGS. 3 and q .. The prechamber itself is denoted by i and the injection valve by k.
Die Anwendung des Einsatzes ist nicht auf Vorkammermotoren beschränkt, er kannebensogut für Luftspeichermotoren verwendet werden.The application of the insert is not limited to pre-chamber engines, it can also be used for air storage motors.
