Description

Vorkammerdieselmaschine Gegenstand der vorliegenden Erfindung ist eine Vorkammerdieselmaschine mit einer zwischen Vorkammer und Arbeitszylinder liegenden Wirbel- und Verteilungsdüse und eineraxial angeordneten Brennstoffdüse. Das Neue gemäß der Erfindung besteht darin, daß die Bohrungen der in an sich bekannter Weise gleichachsig zur Brennstoffdüse angeordneten Wirbel- und Verteilungsdüse als Teile von Schraubengängen auf der Oberfläche eines in den Boden der Vorkammer eingesetzten, mit der ideellen Spitze in die Vorkammer weisenden Kegelstumpfes angeordnet sind.Pre-chamber diesel engine is the subject of the present invention an antechamber diesel engine with a between the antechamber and the working cylinder Swirl and distribution nozzle and an axially arranged fuel nozzle. The new according to the invention consists in that the holes in a manner known per se Swirl and distribution nozzle arranged coaxially to the fuel nozzle as parts of screw threads on the surface of an inserted into the bottom of the antechamber, are arranged with the ideal point in the antechamber pointing truncated cone.

Die Zeichnung zeigt ein Ausführungsbeispiel gemäß der Erfindung, und zwar oben im Schnitt und unten eine Aufsicht auf, den Kegelstumpf mit den Bohrungen.The drawing shows an embodiment according to the invention, and although a section above and a plan view below, the truncated cone with the holes.

In der Zeichnung ist a der Kolben, e die Vorkammer, d der Boden der Vorkammer, f der Kegelstumpf und g die als Teile von Schraubengängen ausgebildeten Bohrungen. Bei der Vorrichtung gemäß der Erfindung wird die Luft durch die auf denn Kegelstumpf f verlaufenden Bohrungen g in die Vorkammer e gedrückt und dadurch eine kräftige Wirbelung der Ladung und somit eine reine Verbrennung erzielt.In the drawing, a is the piston, e is the prechamber, d is the bottom of the prechamber, f is the truncated cone and g is the bores formed as parts of screw threads. In the device according to the invention, the air is pressed through the bores g, which run on the truncated cone f, into the antechamber e, and thereby a powerful swirling of the charge and thus pure combustion is achieved.
