Abstract

The engine has a shaft with two inclined bearing journals (1), and a plate with tapered roller bearings (2) fastened to each journal. These produce wobbling movements when the shaft rotates. Pistons (4), which are movably fastened to the swash plates, are moved axially opposite to each other in cylinder liners. The pistons consist of several plates of different materials. The top plate is of ceramics, the central plates are of carbon, and the bottom plate is conical and made of steel. All plates are fastened via a screw.

Description

Bisher verwendete Verbrennungsmotoren gibt es in Viertakt- und Zweitaktverfahren. Die Viertaktverbrennungsmotoren haben sich im Laufe der Zeit als die besseren bewährt und kommen weltweit zur Anwendung. Der Zweitaktverbrennungsmotor dagegen wird nur noch in Kleingeräten genutzt. Die Ursache dafür sind die Nachteile der Zweitaktmotoren gegenüber den Viertaktmotoren. Die Vorteile des Zweitaktmotors sind, geringerer Materialaufwand, weniger Bauteile. Die Nachteile sind hoher Öl- und Kraftstoffverbrauch und hoher Schadstoffausstoß. Alle genannten Verbrennungsmotoren haben einen Kurbelwellenantrieb und alle gleitenden Teile benötigen eine Ölschmierung. Das Gegendrehmoment dieser Motoren wird von der Kurbelwelle über die Pleuel an die Kolben und diese an die feststehende Zylinderwand abgegeben, dadurch entsteht zwischen gleitenden Kolben und der feststehenden Zylinderwand eine verstärkte Reibung.Combustion engines used so far are available in four-stroke and two-stroke process. The four-stroke internal combustion engines have Proven itself over time as the better ones and come used worldwide. The two-stroke internal combustion engine, on the other hand is only used in small devices. The cause of this are the disadvantages of two-stroke engines compared to four-stroke engines. The advantages of the two-stroke engine are less material, fewer components. The cons are high oil and fuel consumption and high pollutant emissions. All of the above Internal combustion engines have a crankshaft drive and all sliding parts require oil lubrication. The Counter torque of these engines is transferred from the crankshaft the connecting rods to the pistons and these to the fixed cylinder wall released, this creates between sliding pistons and the fixed cylinder wall increased friction.

Die Erfindung stellt sich die Aufgabe einen Gegenkolbenverbrennungsmotor in Taumelscheibenbauart völlig neuartiger Konzeption, der hinsichtlich weniger Bauteile im Zweitaktverfahren mit Aufladung und geringem Kraftstoffverbrauch arbeitet und ohne Ölschmierung betrieben wird. Das Gegendrehmoment wird nicht über die Kolben an die Zylinderwand übertragen.The invention has for its object a counter-piston internal combustion engine Swashplate construction of a completely new concept, of fewer components in the two-stroke process works with charging and low fuel consumption and is operated without oil lubrication. The counter torque is not transmitted to the cylinder wall via the pistons.

Der erfindungsgemäße Gegenkolbenverbrennungsmotor in Taumelscheibenbauart wird im wesentlichen dadurch gekennzeichnet, daß eine Welle 1 mit zwei schrägangeordneten Lagerzapfen in einem feststehenden Gehäuse 8 gelagert ist, an diesen Schräglagerzapfen werden Scheiben 2, die auf Kegelrollenlagern gelagert sind, befestigt. An diesen Scheiben 2 sind am Umfang eine Rolle 11 befestigt, die in einer am Gehäuse 8 befestigten Führung axial beweglich und radial das Gegendrehmoment an das Gehäuse 8 überträgt. An dem Gehäuse 8 sind die Laufbüchsen axial befestigt. In diesen Laufbüchsen 3 sind in je einer Laufbüchse 3 zwei Kolben 4. Die Kolben 4 sind an den Scheiben 2 beweglich befestigt. Bei einer Wellenumdrehung werden die Kolben 4 axial gegenläufig bewegt. Die Laufbüchsen 3 haben Eingangsschlitze 5 und Ausgangsschlitze 6, die von den Kolben gesteuert werden. Die beiden Schräglagerzapfen sind in Drehrichtung versetzt. Dadurch wird erreicht, daß die Kolben 4 ausgangsseitig die Schlitze früher öffnet und auch früher schließt. Die Bohrung 7 in der Mitte der Laufbüchse 3 ist die Öffnung für die Einspritzdüse. An der Einlaßseite des Gehäuses 8 ist das Ladegebläse 9 angeordnet, in der Mitte zwischen den Taumelscheiben das Gebläse für die Kühlung der Laufbüchsen und an der Auslaßseite des Gehäuses 8 eine Abgasturbine 10. Die Kolben 4 bestehen aus mehreren Teilen in Scheibenform aus unterschiedlichem Material, die obere Scheibe besteht aus Keramik, die mittleren Scheiben aus Kohle und die untere Scheibe 12 in Kegelform aus Stahl. Die Scheiben werden mit einer Schraube fest verbunden und an der Taumelscheibe beweglich befestigt. Die Kohlekolben haben gute Gleiteigenschaften und werden seitlich nicht belastet.The swashplate-type counter-piston internal combustion engine according to the invention is essentially characterized in that a shaft 1 with two obliquely arranged bearing journals is mounted in a fixed housing 8 , on these angular bearing journals disks 2 which are mounted on tapered roller bearings are fastened. On these disks 2 a roller 11 are fixed on the periphery of which transmits in a guide fixed to the housing 8 axially movable and radially the counter torque to the housing. 8 The liners are axially attached to the housing 8 . In these liners 3 there are two pistons 4 in each liner 3 . The pistons 4 are movably attached to the disks 2 . When the shaft rotates, the pistons 4 are moved axially in opposite directions. The liners 3 have inlet slots 5 and outlet slots 6 which are controlled by the pistons. The two angular bearing journals are offset in the direction of rotation. It is thereby achieved that the piston 4 opens the slots earlier on the output side and also closes earlier. The bore 7 in the middle of the liner 3 is the opening for the injection nozzle. The charging blower 9 is arranged on the inlet side of the housing 8 , the blower for cooling the liners in the middle between the swash plates and an exhaust gas turbine 10 on the outlet side of the housing 8 . The pistons 4 consist of several parts in the form of disks made of different materials, the upper disk consists of ceramic, the middle disks made of carbon and the lower disk 12 in the form of a cone made of steel. The discs are firmly connected with a screw and movably attached to the swash plate. The carbon pistons have good sliding properties and are not loaded laterally.

Die Vorteile gegenüber einem Kurbelwellenhubmotor im Zweitaktprinzip.
Pleuel, Zylinderkopf sind nicht erforderlich. Die Laufbüchsen werden nicht mit dem Gegendrehmoment des Motors belastet. Die Kraftübertragung wird von der Kegelfläche der Kolben abwälzend an die Taumelscheiben übertragen. Die Kolben aus Kohle und Keramik sind hitzebeständig und schlechte Wärmeleiter. Die Kohle besitzt gute Gleiteigenschaften, so daß der Motor ohne Öl betrieben werden kann.The advantages compared to a crankshaft lifting engine based on the two-stroke principle.
Connecting rods and cylinder heads are not required. The liners are not loaded with the counter torque of the motor. The power transmission is transmitted from the tapered surface of the pistons to the swash plates. The carbon and ceramic pistons are heat-resistant and poor heat conductors. The coal has good sliding properties so that the engine can be operated without oil.
