Description

Zweitaktmotor Zweitaktdoppelkolbenmotoren, die nach dein Dreikanalsystem arbeiten, sind bekannt, haben aber den Nachteil, .daß die öffnungszeiten der Ansaugschlitze sehr gering sind.Two-stroke engine Two-stroke double-piston engines that work according to your three-channel system work, are known, but have the disadvantage, .that the opening times of the suction slots are very low.

Dieser Nachteil soll nun gemäß der Erfindung dadurch vermieden werden, daß Kolben und Zylinder so konstruiert sind, .daß während des ganzen Ansaugehubs die Verbindung der Kurbelgehäusepumpe mit der Speiseleitung hergestellt ist. Verwendet wird die bekannte Motorenbauart mit zwei parallelen Zylindern und gemeinsamem Verbrennungsraum und auf ,eine gemeinsame Welle arbeitenden Kolben, deren einer dem anderen voreilt. Insbesondere empfiehlt es sich auch, die bei solchen Motoren bekannte Versetzung der Kurbelzapfen in dem vom Konstrukteur richtig zu bemessenden Verhältnis anzuwenden.According to the invention, this disadvantage is now to be avoided by that the piston and cylinder are designed in such a way that during the entire intake stroke the connection between the crankcase pump and the feed line is established. Used becomes the well-known engine design with two parallel cylinders and a common combustion chamber and on, a common shaft working pistons, one of which leads the other. In particular, it is also advisable to use the offset known in such motors to use the crank pin in the ratio to be correctly dimensioned by the designer.

Die Zeichnung veranschaulicht nun eine beispielsweise Ausführungsform der Erfindung, und zwar zeigen: Abb. i einen Schnitt der in Abb. 2 dargestellten Anordnung in Richtung A-B, Abb. 2 einen Schnitt der in Abb. i dargestellten Anordnung in Richtung C-D, Abb. 3 einen Schnitt in Richtung E-F der in Abb. q. in der Seitenansicht dargestellten Kurbelwellenanordnung.The drawing now illustrates an example embodiment of the invention, namely: Fig. i shows a section of the one shown in Fig. 2 Arrangement in direction A-B, Fig. 2 a section of the arrangement shown in Fig. I in the direction C-D, Fig. 3 a section in the direction E-F of the in Fig. q. in side view illustrated crankshaft assembly.

In der in Abb. i dargestellten Anordnung befinden sich beide Kolben in der unteren Totpunktlage. Wird nun der Motor in Pfeilrichtung gedreht, so steigt zunächst der Kolben i, während Kolben 2 noch unten bleibt. Der Schlitz 3 des Kolbens i gelangt durch den Hochgang des Kolbens vor den in der Zylinderwand 4.a vorgesehenen ersten Durchgangsschlitz 5, vor welchem schon der im Kolben :2 befindliche Schlitz 6 wartet. Dadurch ist eine offene Leitung geschaffen. Das Frischgas wird nun durch den Vergaseranschluß 7 angesaugt, durchströmt den Kolbenkanal 8, tritt dann durch Schlitze 6, 5, 3 in .die Kurbelkammer. Die Kolben bewegen sich jetzt weiter aufwärts, und das Frischgas wird .durch die Durchgangsschlitze 9, i o, 1i gesaugt. In der oberen Totpunktlage sind wieder alle Schlitze geschlossen. Jetzt erfolgt der sogenannte Vorverdichtungshub. Die drei in den Kolben vorgesehenen unteren Kolbenringe schieben sich vor die Durchgangsschlitze und dichten dieselben ab, so daß kein Gas in den Vergaser zurück kann. Dabei ist die Anordnung der Kolbenringe derart, daß die Durchg.ngsschlitze ii, 1o, 9, 5 nacheinander nicht eher von dem obersten der drei Kolbenringe des Kolbens :2 freigelegt werden, bis der unterste der drei Kolbenringe des Kolbens i denselben Durchgangsschlitz schon verschlossen hat.In the arrangement shown in Fig. I, there are both pistons in the bottom dead center position. If the motor is now turned in the direction of the arrow, it increases first piston i, while piston 2 still remains down. The slot 3 of the piston i passes through the upstroke of the piston in front of the one provided in the cylinder wall 4.a first through slot 5, in front of which the slot located in the piston: 2 is already located 6 is waiting. This creates an open line. The fresh gas is now through sucked in the carburetor connection 7, flows through the piston channel 8, then passes through Slots 6, 5, 3 in. The crank chamber. The pistons keep moving up now and the fresh gas is sucked through the passage slots 9, i o, 1i. In the top dead center all slots are closed again. Now the so-called Pre-compression stroke. Slide the three lower piston rings provided in the piston in front of the through slots and seal them off so that no gas gets into the Carburetor back can. The arrangement of the piston rings is such that the Durchg.ngsschlitze ii, 1o, 9, 5 one after the other not rather from the top of the three piston rings of the piston : 2 are exposed until the lowest of the three piston rings of piston i the same Has already closed the passage slot.

Zwecles Erreichung größerer Kolbenschlitzöffnungen bzw. größerer Durchgangsschlitzöffnungen kann die bekannte Kurbelversetzung größer gehalten werden (vgl. Abb. 3 und ¢). Diese wirkt auch günstig auf Auspuff und Übergangsschlitze. Bei der nun folgenden Drehung erfolgt das Ansteigen der Kolben und die Kompression des Gasluftgemisches. Im oberen Totpunkt findet die Zündung statt, und die Kolben werden infolge der Explosionskraft nach unten gedrückt. Auf diese Art und Weise erfolgt der Antrieb der ganzen Vorrichtung.Purpose of achieving larger piston slot openings or larger through slot openings the known crank offset can be kept larger (see Fig. 3 and ¢). These also has a beneficial effect on the exhaust and transition slots. With the now following rotation the piston rises and the gas-air mixture is compressed. At the top Ignition takes place at dead center, and the pistons become as a result of the force of the explosion pressed down. The entire device is driven in this way.
