Description

Zweitakt-Brennkraftmaschine Gegenstand der vorliegenden Erfindung ist eine Zweitaktkraftmaschine mit einer im Kolben liegenden Durchmischvorrichtung für das zur Kurbelkastenpumpe eintretende Gemisch. Bei den bekannten Motoren bestehen diese Durchmischvorrichtungen im Kolben aus Drahtgaze oder parallel zur Kanalachse geführten Wänden, die den Gemischstrom in feine Fäden zerlegen.Two-stroke internal combustion engine is the subject of the present invention is a two-stroke engine with a mixing device located in the piston for the mixture entering the crankcase pump. In the known engines exist these mixing devices in the piston made of wire gauze or parallel to the channel axis guided walls that divide the mixed flow into fine threads.

Gemäß der Erfindung liegt in einem vom Gemisch durchströmten Kolbenkanal eine Querwand des Kolbens, die mit schräg gef"uhrten bzw. konischen Löchern versehen ist, in einer von Durchmischvorrichtungen im Saugrohr her bekannten Weise.According to the invention lies in a piston channel through which the mixture flows a transverse wall of the piston, which is provided with obliquely guided or conical holes is, in a manner known from mixing devices in the intake manifold.

Die Anwendung dieser Vorrichtungen beim Kolben bietet den Vorteil, daß sie aus einem zum Kolben gehörigen Materialteil leicht führten bzw. konischen Löchern versehen ist, In der Zeichnung ist eine Ausführungsform gemäß der Erfindung dargestellt. Abb. i zeigt einen Motor mit Einrichtung gemäß der Erfindung.The use of these devices on the piston has the advantage that they easily led or conical from a material part belonging to the piston Holes is provided, In the drawing is an embodiment according to the invention shown. Fig. I shows an engine with device according to the invention.

Abb.2 zeigt die Seitenansicht eines Kolbens, der mit einer rechtwinkligen Einbuchtung a versehen ist, wobei die Bohrlöcher in die horizontale und vertikale Wand beispielsweise schräg gebohrt sind.Fig.2 shows the side view of a piston that is connected to a right-angled Indentation a is provided, with the drill holes in the horizontal and vertical Wall, for example, are drilled at an angle.

Abb.3 zeigt die Kolbenwand im Längsschnitt mit den Bohrungen in der vertikalen Wand der Einbuchtung des Kolbens. Die Bohrungen liegen übereinander und sind z. B. unter einem Zylinderwinkel von q.5° gebohrt. Abb. q. zeigt den Querschnitt des Kolbens, bei dem die Bohrungen in der Horizontalwand der Einbuchtung gleichfalls unter demselben Zylinderwinkel ausgeführt sind.Fig.3 shows the piston wall in a longitudinal section with the bores in the vertical wall of the indentation of the piston. The holes are on top of each other and are z. B. drilled at a cylinder angle of q.5 °. Fig.q. shows the cross section of the piston, in which the bores in the horizontal wall of the indentation likewise are carried out at the same cylinder angle.

Die Wirkungsweise dieser Anordnung ist die folgende: Durch den Ansaugkanal des Motors geht das Gemisch in die Einbuchtung des Kolbens und wird durch deren Bohrlöcher hindurch in das Kurbelgehäuse gesaugt. Durch die Bohrungen im Kolben wird die Zerstäubung gefördert, weil das Gemisch an den scharfen Kanten der Bohrlöcher herumgerissen wird und an diesen Stellen eine Durchwirbelung des Brennstoffes vor sich geht.The mode of operation of this arrangement is as follows: Through the intake duct of the engine, the mixture goes into the indentation of the piston and is through its Boreholes sucked through into the crankcase. Through the holes in the piston the atomization is promoted because the mixture on the sharp edges of the drill holes is torn around and at these points a turbulence of the fuel before is going.
