Abstract

The piston has two crowns rigidly joined together to form two combustion chambers. The connecting piece is coupled to a regulator rod whose swinging movements are transferred to a crank shaft connecting rod. The free end of the regulator rod is coupled to a stabiliser rod pivoted to the crank case. The piston design is applicable to all type of i.c. engines. For two-stroke working, one combustion chamber is used as a pre-compression chamber. The combustion and pre-combustion chambers are suitably connected by transfer channels regulated in the usual manner by piston movement. Engine bearing lubrication is by forced feed avoiding the use of a fuel oil mixture.

Description

Beschreibung und Patentansprüche zur Patentanmeldung vom 31.12.76Description and claims for the patent application dated December 31, 1976

Titel: Doppelbodenkolbenmotor Anwendungsgebiet: Die Erfindung betrifft einen Doppelbodenkolben mit Kurbeltrieb für Verbrennungsmotoren.Title: Double bottom piston engine Field of application: The invention relates to a double bottom piston with crank drive for internal combustion engines.

Zweck: Bei Verbrennungsmotoren den Leerlauf und damit den Verschleiß an Kolben und Kurbeltrieb zu verringern.Purpose: In combustion engines, idling and thus wear to reduce the piston and crank mechanism.

Stand der Technik: Es ist bekannt, daß die Kolben bei Diesel-und Ottomotoren nur einen Kolbenboden haben.State of the art: It is known that the pistons in diesel and gasoline engines have only one piston crown.

Ferner ist bekannt, daß je Kolben mit einem Kolbenboden eine Kraftübertragung auf die Kurbelwelle erforderlich ist. It is also known that a power transmission for each piston with a piston head on the crankshaft is required.

Bei den bekannten Zwei-?akt- und Vier-Takt-Motoren erfolgt je Umdrehung der Kurbewelle eine bestimmte Anzahl von Arbeitstakten und zwar beim Zwei-Takt-Motor, vier Arbeitstakte, beim Vier-Takt-Motor, zwei Arbeitstakte. In the known two-stroke and four-stroke engines, one revolution takes place the crank shaft a certain number of work cycles, namely with the two-stroke engine, four working cycles, with the four-stroke engine, two working cycles.

Aufgabe: Herabsetzen des Verschleises an Kolben und Zylinderwänden, sowie Verkleinerung des Motorgehäuses, Verminderung des Gewichtes und der beweglichen Teile.Task: reducing wear on pistons and cylinder walls, as well as reducing the size of the motor housing, reducing weight and moving Parts.

Erhöhung der Leistung und bessere Ausnutzung des Treibstoffes. Increase in performance and better use of fuel.

Seite 2 zur Beschreibung der Petentnweldung vom 31.12.1976 Lösung der Aufgabe und erzielbare Vorteile: Der VerschleiS an Kolben und Zylinderwänden wird herabgesetzt durch eine besondere Anordnung des Kolbens und des dazugehörigen Kurbeltriebes, so daß kein Seitenkippen an den Kolben auftrtt. Siehe Zeichnungs-Blatt Nr. 1 und 2.Page 2 for the description of the petitioner's notification of December 31, 1976 solution the task and achievable advantages: The wear on the piston and cylinder walls is reduced by a special arrangement of the piston and its associated Crank mechanism so that the piston does not tilt to the side. See drawing sheet No. 1 and 2.

Die Verklelnerung des Motorgehäuses ergibt sich daraus, daß je Kolben mit zwei Kolben böden und somit für Je zwei Verbrennungsräume nur ein Zylinder erforderlich ist. The explanation of the motor housing results from the fact that each piston with two piston heads and thus only one cylinder is required for each two combustion chambers is.

Die Verminderung des Gewichtes und die Brhöhung der Leistung ergeben sich aus der Verkleinerung des Motorgehäuses, sowie aus der Verminderung der beweglichen. Ebenso wird dadurch die Betriebstemperatur schneller erreicht. The reduction in weight and the increase in performance result from the reduction of the size of the motor housing, as well as from the reduction of the movable ones. The operating temperature is also reached more quickly.

Vorteile: Bei der Anordnung von zwei Kolbenböden an einem Kolben erfolgen Je Kurbelwellenumdrehung auch beim Vier-Takt-Motor vier Arbeitstakte.Advantages: When arranging two piston heads on one piston Four working cycles per crankshaft revolution, even with a four-stroke engine.

Wird der Doppelbodenkolben bei einem Zwei-Takt-Motor verwendet, entfällt die bisher notwendige Schmierung durch das öl aus dem Kraftstoff-Öl-Luftgemisch. Siehe Zeichnungs-Blatt Nr. 3. If the double bottom piston is used in a two-stroke engine, it is not necessary the previously necessary lubrication by the oil from the fuel-oil-air mixture. See drawing sheet no.3.

Ferner ergeben sich Vorteile in Bezug auf Reparatur und Lagerhaltung der Ersatzteile durch die Verminderung der beweglichen Teile und Verkleinerung des Motorgehäuses. There are also advantages in terms of repair and storage of spare parts by reducing the number of moving parts and reducing the size of the Motor housing.

Ausführungsbeispiele: Zwei Ausführungsbeispiele sind in den Zeichnungen Blatt Nr. 1, 2 und 3 dargestellt.Exemplary embodiments: Two exemplary embodiments are shown in the drawings Sheet No. 1, 2 and 3 shown.

Figur 1 zeigt einen Vier-Takt-Motor, Figur 2 zeigt einen Zwei-Takt-Motor. Figure 1 shows a four-stroke engine, Figure 2 shows a two-stroke engine.
