Abstract

Opposed-piston internal combustion engine in which the piston bores are disposed in a circle in a cylindrical drum. The pistons are moved in opposite directions by two swash plates rotatably mounted on a hollow shaft, itself mounted in the cylindrical drum. Gas exchange is effected through the hollow shaft by a turbo charger mounted in the hollow shaft, the impellers of which are located directly below the intake ports and outlet ports of the piston bores.

Description

Die Erfindung bezieht sich auf einen Gegenkolben-Ver­ brennungsmotor gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a counter-piston Ver Internal combustion engine according to the preamble of claim 1.

Aus der DE-PS 8 85 023 ist bereits ein Gegenkolben-Verbren­ nungsmotor der Art gemäß dem Oberbegriff des Anspruchs 1 be­ kannt. Bei diesem Motor wird eine mechanisch angetriebene Ladevorrichtung, z. B. ein Flügellader verwendet. Die US-PS 85 45 20 765 zeigt einen Gegenkolbenmotor mit einer Ladevor­ richtung. Die Gegenkolben sind auf einer Kurvenbahn geführt. Die Ladeeinrichtung wird von der sich drehenden Kurvenbahn über Zahnräder und Riementrieb angetrieben.From DE-PS 8 85 023 is already a counter-piston combustion voltage motor of the type according to the preamble of claim 1 be knows. This engine uses a mechanically driven one Loading device, e.g. B. uses a wing loader. U.S. Patent 85 45 20 765 shows a counter-piston engine with a charging device direction. The counter pistons are guided on a cam track. The loading device is driven by the rotating cam track driven by gears and belt drive.

Der Erfindung liegt die Aufgabe zugrunde, einen Gegenkolben- Verbrennungsmotor der im Oberbegriff des Anspruchs 1 angegebenen Art so auszubilden, daß die Ladung der Zylinder mit der in den Abgasen enthaltenen Energie erfolgt, wobei die Ladungswechselkanäle so angeordnet sein sollen, daß die Strömung möglichst verlustfrei geführt wird.The invention has for its object a counter-piston Internal combustion engine specified in the preamble of claim 1 Kind in such a way that the charge of the cylinder with that in the Exhaust gas contained energy takes place, the charge exchange channels should be arranged so that the flow is as lossless as possible to be led.

Zur Lösung dieser Aufgabe sieht die Erfindung die im kenn­ zeichnenden Teil des Anspruchs 1 genannten Maßnahmen vor. Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.To solve this problem, the invention provides in the kenn drawing part of claim 1 measures mentioned. Preferred embodiments of the invention result from the Subclaims.

Die Erfindung wird nachfolgend anhand der Zeichnung beschrie­ ben.The invention is described below with reference to the drawing ben.

Fig. 1 ist ein Längsschnitt. Fig. 1 is a longitudinal section.

Fig. 2 ist ein Mittelschnitt durch den erfindungsgemäßen Motor. Fig. 2 is a central section through the engine according to the invention.

In einem Hohlzylinder (Kreiszylinder-Trommel) 1 sind achsparallel mehrere Zylinderbohrungen 2 angebracht, in denen sich je zwei Kolben 3 gegeneinander bewegen. Sind die Kolben 3 in der Mitte, erfolgt nach vorangegangener Kompression die Zündung, sind die Kolben 3 außen, erfolgt der Gasaustausch. Dazu sind Schlitze 4, 5 in den Zylinderbohrungen 2 vorgesehen. Durch den in Fig. 1 linken Schlitz 4 erfolgt die Frischluftzufuhr, durch den rechten Schlitz 5 der Auspuff der Verbrennungsgase. Die Schlitze führen zu den Gebläserädern eines in der Bohrung des Hohlzylinders 1 angeordneten Turboladers 6, der den Gaswechsel und die Aufladung bewirkt.In a hollow cylinder (circular cylinder drum) 1 , a plurality of cylinder bores 2 are provided in which two pistons 3 each move against one another. If the pistons 3 are in the middle, the ignition takes place after the previous compression, if the pistons 3 are on the outside, the gas exchange takes place. For this purpose, slots 4, 5 are provided in the cylinder bores 2 . Fresh air is supplied through the slot 4 on the left in FIG. 1 and the exhaust of the combustion gases through the slot 5 on the right. The slots lead to the fan wheels of a turbocharger 6 arranged in the bore of the hollow cylinder 1 , which causes the gas exchange and the charging.

Der Turbolader 6 ist achsparallel und konzentrisch in einer Hohlwelle 7 gelagert, die wiederum im Hohlzylinder 1 drehbar gelagert ist. Die Hohlwelle 7 ist mit Schlitzen 8 versehen, die die Zylinderbohrungsschlitze 4, 5 jeweils dann mit dem Turbolader 6 verbinden, wenn die Kolben in der äußeren Lage sind und der Gaswechsel erfolgt.The turbocharger 6 is mounted axially parallel and concentrically in a hollow shaft 7 , which in turn is rotatably mounted in the hollow cylinder 1 . The hollow shaft 7 is provided with slots 8 , which connect the cylinder bore slots 4, 5 to the turbocharger 6 when the pistons are in the outer position and the gas exchange takes place.

Die Hohlwelle 7 ist in der Mitte mit einer Scheibe 9 ver­ schlossen. Durch den linken Teil der Hohlwelle 7 erfolgt die Frischluftzufuhr, durch den rechten Teil der Auspuff der Verbrennungsgase.The hollow shaft 7 is closed in the middle with a disk 9 ver. The fresh air is supplied through the left part of the hollow shaft 7 and the exhaust of the combustion gases through the right part.

Auf der Hohlwelle 7 sind zwei Taumelscheiben 10 drehbar ge­ lagert, an denen die Kolben 3 mit Pleueln 11 angelenkt sind. Außerdem ist auf der Hohlwelle 7 ein Ventilator- oder Ge­ bläserad 12 befestigt und fördert Kühlluft und Verbren­ nungsluft, die durch Schlitze 13 in die Hohlwelle einströmt. Das linke Ende der Hohlwelle 7 ist als Vollwelle 14 ausge­ bildet, über die der Abtrieb erfolgt.On the hollow shaft 7 , two swash plates 10 are rotatably supported, on which the pistons 3 are articulated with connecting rods 11 . In addition, a fan or Ge blower wheel 12 is attached to the hollow shaft 7 and promotes cooling air and combustion air that flows through slots 13 into the hollow shaft. The left end of the hollow shaft 7 is formed as a solid shaft 14 through which the output takes place.

Schließlich kann die Treibstoffzufuhr durch einen in der Hohlwelle 7 eingebauten Einlaßteil 20 erfolgen, der an die Zylindertrommel 1 angepreßt ist und jeweils bei bestimmter Kolbenstellung Einlaßdüsen mit der Treibstoffzuleitung verbindet. Der Einlaßteil ist in der Welle längsverschieblich und mit einem keilförmigen Schlitz versehen, so daß durch die Längsverschiebung die Ein­ spritzdauer und damit die pro Hub eingespritzte Treibstoff­ menge verstellbar ist.Finally, the fuel supply can take place through an inlet part 20 built into the hollow shaft 7 , which is pressed against the cylinder drum 1 and connects inlet nozzles with the fuel feed line in each case with a certain piston position. The inlet part is longitudinally displaceable in the shaft and provided with a wedge-shaped slot, so that the injection duration and thus the amount of fuel injected per stroke can be adjusted by the longitudinal displacement.
