Description

Zweitaktmotor mit hohlem Arbeitskolben. Die Erfindung betrifft eine Anordnung bei Zweitaktmotoren mit hohlem Arbeitskolben, welcher auf einen, feststehenden: Block gleitet und während der Aufwärtsbewegung das Brennstoffluftgemisch ansaugt und beim Rückgang verdichtet und in den Zylinder eintreibt. Gemäß der Erfindung wird am Fuße des Zylinders, entweder in demselben oder im feststehenden Block, ein ringförmiger Kanal angeordnet,durch welchen das Brenn.stoffluftgemisch auf seinem Weg vom Innern des Arbeitskolbens nach dem Zyliniderinnen@raum strömen muß. Außerdem wird das Brennstoffluftgemisch vom Innern des Kolbens aus durch enge Kanäle, welche im feststehenden Block angeordnet sind, getrieben. Hierdurch wird eine innige Vermischung von Brennstoff und Verbr.ennungslüft erreicht, wodurch der Eintritt flüssigen Brennstoffes in den Zylinderraum verhindert wird.Two-stroke engine with a hollow working piston. The invention relates to a Arrangement for two-stroke engines with a hollow working piston, which is mounted on a fixed: Block slides and sucks in the fuel-air mixture during the upward movement and compresses as it retreats and drives it into the cylinder. According to the invention will be at the base of the cylinder, either in the same or in the fixed block annular channel arranged through which the fuel air mixture on his Must flow away from the inside of the working piston to the cylinder inner space. aside from that the fuel-air mixture is drawn from inside the piston through narrow channels, which are arranged in the stationary block, driven. This creates an intimate mixture of fuel and combustion air reached, whereby the entry of liquid fuel is prevented in the cylinder space.

Eine Ausführungsform der Erfindung ist auf der Zeichnung veranschaulicht, und zwar zeigt Fig. 1 einen Einzylinder-Zweitaktmotor in senkrechtem Schnitt, und Fig. 2 einen Schnitt nach der Linie II-II in Fig 1.An embodiment of the invention is illustrated in the drawing, namely Fig. 1 shows a single-cylinder two-stroke engine in vertical section, and FIG. 2 shows a section along the line II-II in FIG. 1.

Vom Saugventil 3 des Motors führt ein Kanal 4 zum Einlaßventil5 des Motorzylinders. Der Arbeitsraum des Motorzylinders ist mit 6 und sein Arbeitskolben mit 7 bezeichnet. Letzterer ist in bekannter Weise durch Dichtungsringe 8 gegen die Zylinderwand des Motors gedichtet. Quer durch den, Kolben 7 geht ein Zapfen g, der mittels einer Pleuelstange 1o mit dem Kurbelzapfen 11 des Motors verbunden ist. Der Arbeitsraum 6 des Motors hat einen oder mehrere Auslaßkanäle 13.From the suction valve 3 of the engine, a channel 4 leads to the inlet valve 5 of the Engine cylinder. The working space of the engine cylinder is 6 and its working piston denoted by 7. The latter is in a known manner by sealing rings 8 against the cylinder wall of the engine is sealed. A pin goes across the piston 7 g, which is connected to the crank pin 11 of the engine by means of a connecting rod 1o is. The working space 6 of the engine has one or more outlet ducts 13.

Der Kolben 7 des Motors ist hohl. Er gleitet in bekannter Weise auf einen feststehenden Block 14 mit Dichtungsringen 15. Der Block 14 ist mit einem zwischen dem Motorzylinder und dem Kurbelgehäuse 12 eingeschalteten Ring oder Scheibe 17 fest verbunden. In dem Block sind enge Kanäle 18 und 1g angebracht, welche den Raum 2o über dem Block 14 mit einem ringförmigen Kanal 21 im Körper 17 verbinden. Letzterer Kanal ist mittels eines Kanales 22 mit dem Saugventil 3 und dem Kanal 4 verbunden.The piston 7 of the engine is hollow. It slides on in a familiar way a stationary block 14 with sealing rings 15. The block 14 is with a ring or washer interposed between the engine cylinder and the crankcase 12 17 firmly connected. Narrow channels 18 and 1g are made in the block, which the Connect space 2o above block 14 to an annular channel 21 in body 17. The latter channel is by means of a channel 22 with the suction valve 3 and the channel 4 connected.

Der Motor arbeitet in folgender Weise: Wenn der Kolben 7 sich nach oben bewegt und das im Arbeitsraum 6 des Zylinders vorhandene Brennetofluftgemisch komprimiert, wird .durch das Ventil 3 und, die Kanäle 22, 21, i9 und 18 Gemisch nach dem Innern 2o des Kolbens 17 gesaugt. Beim Niedergang des Kolbens wird das im Innern 2o desselben vorhandene Brennstoffluftgemisch komprimiert und durch die Kanäle 18 und 1g in den ringförmigen Kanal 21 und aus diesem in die Kanäle 22 und 4 getrieben.The engine works in the following way: When the piston 7 is after moved above and the fuel air mixture present in the working space 6 of the cylinder compressed, is .by the valve 3 and, the channels 22, 21, i9 and 18 mixture sucked into the interior of the piston 17. When the piston descends, that becomes inside 2o the same existing fuel-air mixture compressed and through the Channels 18 and 1g into the annular channel 21 and out of this into the channels 22 and 4 driven.

Durch die Erfindung wird der Vorteil erreicht, daß das Brennstoffluftgemisch von dem Innern des Kolbens 7 durch die Kanäle 18 und 1g mit großer Geschwindigkeit in. den Kanal 21 hineintritt. Dadurch wird jeder der Brennstoffstrahlen., die von den Kanälen 18, 1 g ausströmen und in dem Kanal 21 die Wand desselben treffen, zerstäubt und in, dem Kanal 21 umgewirbelt, wodurch eine sehr enge Vermischung von Brennstoff und der Verbrennungsluft und eine weitgehende Zerstäubung des Brennstoffs erreicht wird. Durch diese Zerstäubung wird der Eintritt von flüssigem Brennstoff in den Zylinderraum 6 verhindert.The invention has the advantage that the fuel-air mixture from the inside of the piston 7 through the channels 18 and 1g at great speed into. the channel 21 enters. This will cause each of the fuel jets the channels 18, 1 g flow out and hit the wall of the same in the channel 21, atomized and in, the channel 21 whirled around, creating a very close intermingling of fuel and the combustion air and an extensive atomization of the fuel is achieved. This atomization allows liquid fuel to enter prevented in the cylinder space 6.
