Description

Es sind bereits verschiedene Mittel vorgeschlagen worden, um ein und denselben Motor mit verschieden hoher Verdichtung arbeiten zu lassen.Various means have been proposed to make one and the same engine to work with different levels of compression.

Von den bekannten Einrichtungen dieser Art unterscheidet sich der Erfindungsgegenstand dadurch, daß der Kolben mit zwei oder mehr übereinanderliegenden Bolzenbefestigungsstellen ausgestattet ist, so daß je nachThe subject of the invention differs from the known devices of this type in that the piston with two or more superimposed bolt attachment points is equipped so that depending on

ίο dem gewünschten Verdichtungsgrad der Bolzen der Kolbenstange in seiner Lage irinerhalb des Kolbens verändert werden kann. Je mehr der Bolzen nahe an die dem Verbrennungsraum zugekehrte Kolbenoberfläche herangebracht wird, desto mehr wird der Verdichtungsgrad des Motors herabgesetzt. Umgekehrt erhöht sich der Verdichtungsgrad des Motors, wenn sich der Bolzen der Kolbenstange von der Kolbenöberfläche entfernt.ίο the desired degree of compression of the bolts the position of the piston rod within the piston can be changed. Ever the more the pin is brought closer to the piston surface facing the combustion chamber the more the compression ratio of the engine is reduced. Conversely, the degree of compaction increases Engine when the piston rod bolt moves away from the piston surface.

so Der nette Kolben ist besonders geeignet für Motoren, welche mit verschiedenen Brennstoffen betrieben werden, die einen verschiedenen Verdichtungsgrad erforderlich machen. Der Erfindungsgegenstand ist auf beiliegender Zeichnung in einer Ausführungsform in Unteransicht und Längsschnitt veranschaulicht. ' ■so The nice flask is particularly suitable for Engines that run on different fuels that have a different Make the degree of compaction necessary. The subject of the invention is on the enclosed Drawing illustrated in one embodiment in bottom view and longitudinal section. '■

Das dargestellte Ausführungsbeispiel zeigt einen Kolben α mit zwei übereinanderliegenden Befestigungsstellen für den Bolzen derThe illustrated embodiment shows a piston α with two superimposed fastening points for the bolt

Kolbenstange; die untere, dem Kolbenboden entferntere Befestigungsstelle besteht aus zwei gegenüberliegenden Bolzenäugen b. Die beiden dem Kolbenboden näherliegenden Bolzenaugen c liegen gegen die Bolzeriaugen b um 900 versetzt. Beim Umstellen dfes Bolzens muß also der Kolben α ebenfalls um 90° gedreht werden. Durch die Versetzung der Bolzenaugen b und c gegeneinander kann der gegenseitige Abstand e der Mittelachsen derselben möglichst klein gehalten werden.Piston rod; the lower fastening point, further away from the piston crown, consists of two opposing pin eyes b. The two closer to the piston head bolt eyes c abut against the Bolzeriaugen b offset by 90 0th When changing over the bolt, the piston α must also be rotated by 90 °. By offsetting the bolt eyes b and c from one another, the mutual distance e between the central axes of the same can be kept as small as possible.

Die Anordnung kann jedoch auch derart getroffen sein, daß die Achsen der Bolzenaugen c und" b sich nicht kreuzen, sondern parallel liegen oder gegen einen anderen Win- 4S kel als 90 ° gegeneinander versetzt sind.However, the arrangement may be also such that the axes of the pin bosses c and "b does not intersect, but are parallel or against another angular 4 S kel than 90 ° are offset from each other.
