Description

Viertakt-Vorkammerbrennkraftmaschine mit Selbstzündung des in die hochverdichtete Verbrennungsluft eingespritzten Brennstoffes Die Erfindung betrifft eine Viertakt-Vorkammerbrennkraftmaschine mit Selbstzündung des in die hochverdichtete Verbrennungsluft eingespritzten Brennstoffes. Es ist bei solchen Maschinen bereits bekannt, im Zylinderkopf das hängende Lufteinlaßventil auf der einen Seite und die Vorkammer auf der anderen Seite anzuordnen.Four-stroke pre-chamber internal combustion engine with compression ignition of the in the Highly compressed combustion air injected fuel The invention relates a four-stroke pre-chamber internal combustion engine with compression ignition of the high-compression Combustion air injected fuel. It is already there with machines like this known, in the cylinder head the hanging air inlet valve on one side and the To arrange antechamber on the other side.

Erfindungsgemäß sind bei vorliegender, im Viertaktverfahren arbeitenden Maschine die Ventile im Zylinderkopf in an sich bekannter Weise hängend angeordnet, und die Vorkammer ist im Zylinderkopf zwischen den Ventilen so zur Zylinderachse geneigt, daß die Einspritzdüse an der den Ventilstutzen entgegengesetzten Seitenwand des Zylinderkopfes außerhalb der Ventilhaube liegt.According to the present invention, working in the four-stroke process Machine, the valves in the cylinder head are arranged hanging in a known manner, and the prechamber is in the cylinder head between the valves so to the cylinder axis inclined that the injection nozzle on the side wall opposite the valve connector of the cylinder head is outside the valve cover.

Die Abb. I zeigt die neue Anordnung der Vorkammer und die Einspritzdüse in dem senkrecht geschnittenen, auf den Zylinder gesetzten Zylinderkopf i mit den hängenden Ventilen 2, deren Kanäle 3 auf der einen Seite des Kopfes liegen. Die schräg angeordnete Vorkammer4 ist in den Zylinderkopf zwischen den Ventilen eingebaut, und ihre Achse ist so zur Zylinderachse geneigt, daß die Einspritzdüse 5 auf der den Ventilkanälen 3 entgegengesetzten Seite und außerhalb der Ventilhaube 6 liegt.Fig. I shows the new arrangement of the prechamber and the injection nozzle in the vertically cut cylinder head i placed on the cylinder with the hanging valves 2, the channels 3 of which are on one side of the head. the angled prechamber4 is built into the cylinder head between the valves, and its axis is inclined to the cylinder axis that the injection nozzle 5 on the the side opposite the valve channels 3 and outside the valve cover 6.

Die Abb. 2 stellt einen waagerechten Schnitt durch den Zylinderkopf i etwa in Höhe der Ventilkanäle 3 dar und läßt die Lage der Vorkammer 4 zwischen den Ventilen ? erkennen.Fig. 2 shows a horizontal section through the cylinder head i is approximately at the level of the valve channels 3 and leaves the position of the prechamber 4 between the valves? recognize.

Die Vorkammer kann beliebig gestaltet, gekühlt oder ungekühlt, eingegossen oder als Retorte eingesetzt sein. Der zwischen der Vorkammer und dem Zylinder vorgesehene Einsatz - kann mit glatten Zerstäubungslöchern oder mit schraubenförmigen Kanälen versehen sein, welch letztere zur Bildung eines Brennstoffluftwirbels in der Vorkammer und im Verbrennungsraum des Zylinders dienen. Ein solcher Einsatz 8 mit schraubenförmigen Kanälen 9 ist in der Abb. i beispielsweise in einer eingegossenen und gekühlten Vorkammer 4 dargestellt.The antechamber can be designed as desired, cooled or uncooled, cast or used as a retort. The one provided between the antechamber and the cylinder Insert - can be with smooth spray holes or with helical channels be provided, the latter for the formation of a fuel air vortex in the antechamber and serve in the combustion chamber of the cylinder. Such an insert 8 with helical Channels 9 is in Fig. I, for example, in a cast and cooled Pre-chamber 4 shown.

Dadurch, daß die Vorkammer zwischen den beiden Ventilen schrägliegend angeordnet ist, wird neben gleich guter Verbrennung wie bei zentraler Anordnung eine leichte Zugänglichkeit der Einspritzdüse erzielt. Bei Motoren mit Ventilhaube empfiehlt sich eine solche Neigung der Vorkammer, daß die Düse ohne Abnahme der Haube zugänglich ist. Andererseits sind auch die auf der anderen Seite liegenden Ventilstutzen bequem zugänglich. Durch die erwähnte Anordnung wird noch eine gute Wärmeverteilung und erhöhte Festigkeit des Zylinderkopfgußstückes erzielt.Because the antechamber between the two valves is inclined is arranged, is next to the same good combustion as with a central arrangement easy accessibility of the injection nozzle achieved. For engines with a valve cover it is recommended that the antechamber be inclined so that the nozzle can be opened without removing the Hood is accessible. On the other hand, there are also those on the other side Conveniently accessible valve stubs. The aforementioned arrangement makes a good one Heat distribution and increased strength of the cylinder head casting achieved.
