Description

Die Erfindung betrifft einen Zweitaktmotor mit einem Kolben nach dem Hub- und Drehkolbenverfahren.The The invention relates to a two-stroke engine with a piston after Lifting and lobe method.

Aus der Druckschrift DE 25 02 646 A1 ist ein gattungsgemäßer Zweitaktmotor bekannt.From the publication DE 25 02 646 A1 is a generic two-stroke engine known.

Aus der Druckschrift FR 2 739 412 A ist ein weiterer nach dem Hub- und Drehkolbenverfahren arbeitenden Zweitaktmotor bekannt, wobei die Drehbewegung des Kolbens mit Hilfe von Nocken, die zwischen dem Kolben und dem mit der Pleuelstange feststehenden Kolbenbolzens angeordnet sind, erfolgt.From the publication FR 2 739 412 A is another working according to the lifting and rotary piston method two-stroke engine known, wherein the rotational movement of the piston by means of cams, which are arranged between the piston and the piston rod fixed with the connecting rod, takes place.

Derartige Zweitakt-Hub-Dreh-Kolbenmotoren arbeiten mit Gemisch.such Two-stroke stroke rotary piston engines work with mixture.

Es ist Aufgabe der vorliegenden Erfindung, einen Zweitaktmotor zu schaffen, der ohne Gemisch und somit umweltfreundlich arbeitet.It object of the present invention to provide a two-stroke engine, which works without mixture and thus environmentally friendly.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass der Zweitaktmotor mit einem Kolben nach dem Hub- und Drehkolbenverfahren arbeitet, wobei der Kolben in einem Zylinder zwischen zwei Zylinderköpfen sich hin- und herbewegt und an seinen zwei Kolbenenden zwei Brennräume begrenzt, wobei durch eine an der Seite des Kolbens befestigte Pleuelstange eine Antriebswelle in einer Drehbewegung versetzt wird und wiederum die Drehbewegung der Antriebswelle den Kolben seitlich um seine Achse hin und her verdreht. Der Gaswechsel wird durch den Kolben derart gesteuert, dass in den jeweiligen Brennräumen ein Auspuffschlitz (11) und ein Ansaugschlitz (6) durch eine Kolbenkammer (3) geöffnet und geschlossen werden. Der Wegfall des Ansaugens über ein Kurbelgehäuse erlaubt es, dass der Kolben ohne Gemisch arbeiten kann.According to the invention, this object is achieved in that the two-stroke engine operates with a piston by the lifting and rotary piston method, wherein the piston reciprocates in a cylinder between two cylinder heads and limits two combustion chambers at its two piston ends, with one at the side the piston fastened connecting rod is a drive shaft in a rotational movement is added and in turn rotates the rotation of the drive shaft, the piston laterally about its axis back and forth. The gas exchange is controlled by the piston such that in the respective combustion chambers an exhaust slot ( 11 ) and a suction slot ( 6 ) by a piston chamber ( three ) are opened and closed. The omission of suction via a crankcase allows the piston to operate without a mixture.

In den Zeichnungen ist die Erfindung anhand eines Ausführungsbeispiels näher erläutert. In den Zeichnungen stellen dar:In The drawings, the invention is based on an embodiment explained in more detail. In The drawings show:

1 eine perspektivische Ansicht eines Motorblocks mit einer Antriebswelle, 1 a perspective view of an engine block with a drive shaft,

2 eine perspektivische Ansicht eines Kolbens mit einer Pleuelstange und Kolbenkammern, 2 a perspective view of a piston with a connecting rod and piston chambers,

3 eine vereinfachte Darstellung der zwei Takte. three a simplified representation of the two bars.

Die 1 zeigt eine perspektivische Ansicht eines Motorblocks 5 mit einem Kolben 1, einer Antriebswelle 8, einem Hauptlager 7, einem Pleuellager 9, einem Ansaugschlitz 6, einem Auspuffschlitz 11 und einer Zylinderkopfbefestigung 10.The 1 shows a perspective view of an engine block 5 with a piston 1 , a drive shaft 8th , a main camp 7 , a connecting rod bearing 9 , a suction slot 6 , an exhaust slot 11 and a cylinder head attachment 10 ,

Die 2 zeigt eine perspektivische Ansicht des Kolbens 1, der eine Pleuelstange 4, Kolbenkammern 3 und Kolbenringen 2 aufweist.The 2 shows a perspective view of the piston 1 who has a connecting rod 4 , Piston chambers three and piston rings 2 having.

Die 3 zeigt darüber hinaus eine vereinfachte Darstellung der zwei Takte des Hub-Dreh-Kolbenmotors. Der Kolben 1 begrenzt an seiner jeweiligen Enden zwei Brennräume. Der Gaswechsel erfolgt durch Kanäle. Der Kolben steuert in den jeweiligen Brennräumen ein Ansaugkanal und ein Auspuffkanal. Durch das Zusammenwirken der Hub- und Drehbewegung des Kolbens 1 und seiner Kolbenkammer 3 werden in den jeweiligen Brennräumen der Auspuffschlitz 11 und der Ansaugschlitz 6 geöffnet und geschlossen.The three also shows a simplified representation of the two strokes of the stroke rotary piston engine. The piston 1 limited at its respective ends two combustion chambers. The gas exchange takes place through channels. The piston controls in the respective combustion chambers, an intake passage and an exhaust passage. Through the interaction of the lifting and rotating movement of the piston 1 and his piston chamber three in the respective combustion chambers the exhaust slot 11 and the intake slot 6 opened and closed.
