Abstract

Both pistons (1) have the same shape and are located in a cylindrical housing (2) that has an induction opening and an exhaust opening for gases. The pistons divide the cylindrical space into four working chambers. Depending on whether the engine operates as a spark ignition engine or as a diesel engine, a spark plug or an injection nozzle for fuel (3) is located in the cylindrical housing. The sealed pistons move in the same direction about a common axis. The pistons are, independent of one another, connected to the crankshaft (4) via identical, however, reversed transfer systems of the drive (5). The engine is started by a starter via a flywheel (6) that is mounted on the crankshaft. The crankshaft causes, via drive systems, a displacement of the piston inside the housing during which the second piston is simultaneously blocked. The engine starts, and the pistons execute a half revolution in a cyclically alternating manner. Every half revolution of the pistons causes four volume changes corresponding to the four strokes of the four-stroke combustion engine meaning that successive cycles (strokes): induction stroke, compression stroke, working stroke and exhaust stroke, are executed at each moment of displacement of the pistons. The drive system transfers the power from the piston to the crankshaft. According to the position of the eccentric wheels of the crankshaft, the system, during ignition, blocks the piston for a longer or shorter time. All induction, compression, working, and exhaust strokes always occur in the same position of the engine. During each revolution of both pistons, 16 cycles (strokes) i.e. 4 induction strokes, 4 compression strokes, 4 working strokes and 4 exhaust strokes occur inside the motor. At the same time, the crankshaft makes two complete revolutions. An in-line engine can be easily constructed from units of this type. In order to obtain a turbo effect, the engine housing in one unit of the in-line engine has to be modified in such a manner that this unit simultaneously operates in the system with two induction strokes and two compression strokes. This element of the engine thus assumes the function of the rotary compressor.

Description

Vielfacher Viertakt-Rotations-VerbrennungsmotorMultiple four-stroke rotary internal combustion engine
Die Erfindung betrifft den mechanischen Teil. Beim derzeitigen Stand der Technik benötigt ein Viertakt-Verbrennungsmotor, so wie er für verschiedenste Antriebe eingesetzt wird, zwei Umdrehungen der Kurbelwelle zur Erledigung eines Arbeitsganges. Die Drehkolben-Motoren, wie z. B. der Wankelmotor, ermöglichen einen ganzen Arbeitszyklus bei einer Umdrehung des Kolbens oder der Antriebswelle. Beim derzeitigen Entwicklungsstand ist er nicht konkurrenzfähig zum klassischen Verbrennungsmotor. Der vielfache Viertakt-Rotations- Verbrennungsmotor eliminiert die Mängel der oben genannten Motoren und nutzt ihre Vorteile. Bei seinem einfachen Verfahren werden während einer ganzen Umdrehung seiner Kurbelwelle zwei ganze Zyklen eines Viertakt- Verbrennungsmotors verrichtet. The invention relates to the mechanical part. In the current state of the art, a four-stroke internal combustion engine, such as that used for a wide variety of drives, requires two revolutions of the crankshaft to complete one operation. The rotary lobe motors, such as. B. the Wankel engine, allow an entire working cycle with one revolution of the piston or the drive shaft. At the current stage of development, it is not competitive with the classic internal combustion engine. The multiple four-stroke rotary internal combustion engine eliminates the shortcomings of the above-mentioned engines and takes advantage of them. In his simple method, two whole cycles of a four-stroke internal combustion engine are performed during one revolution of his crankshaft.
Gegenstand der Erfindung ist ein vielfacher Viertakt-Rotations-Verbrennungsmotor mit zwei Kolben, die um eine gemeinsame Achse rotieren. Beide Kolben [1] haben die gleiche Form und befinden sich in einem zylindrischen Gehäuse [2], dass eine Ansaugöffnung und eine Auslassöffnung für Gase besitzt. Die Kolben teilen den Zylindrischen Raum in vier Arbeitskammern auf. In Abhängigkeit davon, ob der Motor als Otto- oder Diesel-Motor arbeitet, befindet sich im zylindrischen Gehäuse eine Zündkerze oder eine Einspritzdüse für Kraftstoff [3]. Die abgedichteten Kolben bewegen sich um eine gemeinsame Achse in die gleiche Richtung. Die Kolben sind unabhängig voneinander über gleiche, aber umgekehrte Übertragungssysteme des Antriebs [5], mit der Kurbelwelle [4] verbunden. Der Motor wird durch einen Anlasser über ein Schwungrad [6], dass an der Kurbelwelle angebracht ist, gestartet. Über Antriebssysteme erzwingt die Kurbelwelle eine Verschiebung des Kolbens im Gehäuse. Gleichzeitig wird der zweite Kolben blockiert. Der Motor startet. Die Kolben bewegen sich zyklisch abwechselnd umeine halbe Umdrehung. Jede Bewegung der Kolben um eine halbe Umdrehung verursacht vier Volumenänderungen, was den vier Takten des Viertakt-Verbrennungsmotors entspricht, das bedeutet, dass in jedem Moment der Verschiebung der Kolben folgende Takte (Hübe) ausgeführt werden: Ansaugtakt, Verdichtungstakt, Arbeitstakt und Ausstoßtakt.The subject matter of the invention is a multiple four-stroke rotary internal combustion engine with two pistons rotating about a common axis. Both pistons [1] have the same shape and are located in a cylindrical housing [2] that has a suction opening and an outlet opening for gases. The pistons divide the cylindrical space into four working chambers. Depending on whether the engine works as a petrol or diesel engine, there is a spark plug or an injection nozzle for fuel in the cylindrical housing [3]. The sealed pistons move in the same direction about a common axis. The pistons are connected to the crankshaft [4] independently of one another via the same but reverse transmission systems of the drive [5]. The engine is started by a starter via a flywheel [6] attached to the crankshaft. The crankshaft forces the piston to move in the housing via drive systems. At the same time, the second piston is blocked. The engine starts. The pistons alternate cyclically by half a revolution.

Das Antriebssystem überträgt die Leistung vom Kolben auf die Kurbelwelle. In Abhängigkeit von der Stellung der Excenterrader der Kurbelwelle, blockiert das System bei der Zündung den Kolben für längere oder kürzere Zeit. Alle Ansaug-, Verdichtungs-, Arbeits- Arbeits- und Ausstoßtakte passieren immer in der gleichen Stellung des Motors. Bei jeder Umdrehung der beiden Kolben im Motor erfolgen 16 Takte (Hübe), das heißt:The drive system transfers the power from the piston to the crankshaft. Depending on the position of the eccentric wheels of the crankshaft, the system blocks the piston for a longer or shorter time when it is ignited. All intake, compression, work, work and exhaust cycles always happen in the same position of the engine. With each revolution of the two pistons in the engine there are 16 cycles (strokes), which means
- 4 Ansaugtakte- 4 suction cycles
- 4 Verdichtungstakte- 4 compression cycles

- 4 Ausstoßtakte- 4 ejection strokes

Prinzip und Arbeitsweise des vielfachen Viertakt-Rotations-Verbrennungsmotors.Principle and mode of operation of the multiple four-stroke rotary combustion engine.
Mindestens zwei Kolben in beliebiger Form sind auf einer gemeinsamen Drehachse angebracht. Sie befinden sich in einem abgedichteten Gehäuse und drehen sich in die gleiche Richtung. Sie sind mit einem Antriebssystem verbunden, das bei der Bewegung eines Kolbens gleichzeitig den anderen Kolben blockiert. Das bewirkt, dass der Motor bei einer kompletten Drehung der Kolben um die eigene Drehachse mindestens 16Takte verrichtet, das sind mindestens 4 Ansaugtakte, 4 Verdichtungstakte, 4 Arbeitstakte und 4 Ausstoßtakte. Es ist bezeichnend, dass das bisher unbewegliche Teil des Motors in Bewegung gebracht wurde und dadurch ein Motor mit Rotationskolben in der Lage ist die vielfache Arbeit des Viertakt- Verbrennungsmotors innerhalb einer vollen Umdrehung des Kolbens zu verrichten.At least two pistons of any shape are mounted on a common axis of rotation. They are in a sealed housing and turn in the same direction. They are connected to a drive system that simultaneously blocks the other piston when one piston moves. This causes the engine to perform at least 16 cycles when the pistons are completely rotated about its own axis of rotation, i.e. at least 4 intake cycles, 4 compression cycles, 4 work cycles and 4 exhaust cycles. It is significant that the previously immovable part of the engine has been set in motion, which means that an engine with a rotary piston is able to perform the multiple work of the four-stroke internal combustion engine within one full revolution of the piston.

Vielfacher Rotations-Verbrennungsmotor als Rotationspumpe.Multiple rotary internal combustion engine as a rotary pump.
Es ist bezeichnend, dass durch eine entsprechende Konstruktion des Motorgehäuses bei jeder Bewegung der Kolben gleichzeitig zwei Ansaugtakte und zwei Verdichtungstakte entstehen und dadurch der Motor die Funktion einer Rotationspumpe übernimmt. It is significant that a corresponding construction of the motor housing results in two suction cycles and two compression cycles at the same time with each movement of the pistons, and as a result the motor takes over the function of a rotary pump.
