Description

Es handelt sich um einen vier Takt Verbrennungsmotor, bei dem der Kolben nicht üblicherweise in einem festen Zylinder sich nach oben und unten bewegt, sondern Kolben und Zylinder bewegen sich in einer Richtung. Das heißt, wenn der Kolben den unteren Totpunkt erreicht, schiebt sich der Zylinder über den Kolben nach unten bis der Kolben zu dem oberen Totpunkt gelangt. Dann bewegt sich der Kolben wieder nach unten bis er den unteren Totpunkt erreicht. Dieser Zyklus wiederholt sich im Kreis unendlich weiter. Eine solche Brennkraftmaschine ist beispielsweise aus US 1285835 bekannt.It is a four-stroke internal combustion engine in which the piston is not usually in a fixed cylinder moves up and down, but the piston and cylinder move in one direction. That is, when the piston reaches bottom dead center, the cylinder slides down over the piston until the piston reaches top dead center. Then the piston moves down again until it reaches bottom dead center. This cycle is repeated in circles infinitely. Such an internal combustion engine is for example off US 1285835 known.

Einstellbare Verdichtung und einstellbare Ventilzeit ermöglichen optimale Verbrennung. Durch federloses Drehschiebeventil mit seinem maximalen Durchlassquerschnitt erreicht man beste Füllung.Adjustable compression and adjustable valve time allow optimal combustion. By means of a springless rotary valve with its maximum passage cross-section, best filling is achieved.

Es wird hiermit höchste Leistung, minimaler schädliche Stoffe im Abgas und Verwendung verschiedener Kraftstoffe möglich.It is hereby possible highest performance, minimal harmful substances in the exhaust and use of different fuels.

Techniktechnology

Um ein festes Zahnrad(1) dreht sich ein gleich großes Planetzahnrad(2). Das Planetzahnrad(2) ist auf der Inneren-Scheibe(3) gelagert. Diese Scheibe ist in der Mitte des Festen Zahnrades(1) gelagert. Eine Kurbel(4), die gleich lang wie der Radius des Planetzahnrad(2) ist, bewegt über den Pleuel(5) den Hebel(6). Dieser Hebel(6) ist mit einem Ende auf der äußeren Scheibe(7) gelagert. Das andere Ende ist verbunden über die Stange(8) mit dem Kolben(9). Der Zylinder(10) ist auf der äußeren Drehscheibe(7) fest verbunden. Mit der Verdichtung Stellvorrichtung(13) wird die innere Scheibe(3) an der Äußeren Scheibe(7) verschoben. Dadurch wird der Pleuel(5) gezogen oder gestoßen, Stellung des Hebel(5) und das Verdichtungsverhältnis geändert.(Bild 1)To a fixed gear (1), an equally large planetary gear (2) rotates. The planetary gear (2) is mounted on the inner disc (3). This disc is mounted in the middle of the fixed gear (1). A crank (4), which is the same length as the radius of the planetary gear (2) moves over the connecting rod (5) the lever (6). This lever (6) is mounted with one end on the outer disc (7). The other end is connected via the rod (8) with the piston (9). The cylinder (10) is fixedly connected to the outer hub (7). With the compression adjustment device (13), the inner disc (3) on the outer disc (7) is moved. As a result, the connecting rod (5) is pulled or pushed, the position of the lever (5) and the compression ratio changed (Fig.

Für eine einfache Herstellung ist statt zwei Zahnräder, eine Zahnraddurchmesser lange, wo die zwei Zahnräder zusammen greifen an das Gehäuse gelagerte Stange unten(12) und eine andere Zahnradradius lange Kurbel(4) wie in Bild 2 dargestellt einzusetzen wobei die Lagerung der Inneren-Scheibe(3) nicht in der Mitte, sondern außen ist (Bild 2).For ease of manufacture, instead of two gears, one gear diameter is long, where the two gears engage together to mount the housing-mounted rod below (12) and another gear radius long crank (4) as shown in Figure 2 where the bearing of the inner disk (3) not in the middle, but outside (picture 2).

Ein an der äußere Scheibe (7) angebrachtes Freilauf verhindert, dass die Scheibe sich rückwärts dreht.A freewheel mounted on the outer disc (7) prevents the disc from rotating backwards.

Funktionfunction

Durch Drehung die Scheiben (3 und 7) dreht die Kurbel(4), schiebt über den Pleuel(5) den Hebel(6), der den Kolben(9) nach unten zu dem unteren Totpunkt zieht.By rotating the discs (3 and 7), the crank (4) rotates, pushing over the connecting rod (5) the lever (6), which pulls the piston (9) down to the bottom dead center.

Wenn der Kolben(9) den unteren Totpunkt erreicht, bleibt er im Verhältnis zu der Drehbewegung stehen, weil die Kurbel(4) den Pleuel(5) zurück zieht. Aber der an der Äußeren Scheibe(7) befestigter Zylinder(10) bewegt sich weiter, bis der Kolben(9) den oberen Totpunkt erreicht.When the piston (9) reaches the bottom dead center, it remains in proportion to the rotational movement, because the crank (4) pulls back the connecting rod (5). But the cylinder (10) fixed to the outer disk (7) continues to move until the piston (9) reaches top dead center.

Erreicht der Kolben(9) den oberen Totpunkt, drückt die Kurbel(4) den Pleuel(5) wieder, so bewegt sich der Kolben(9) nach unten bis er den unteren Totpunkt erreicht.If the piston (9) reaches the top dead center, the crank (4) pushes the connecting rod (5) again, then the piston (9) moves downwards until it reaches the bottom dead center.

Dieser Arbeitsablauf wiederholt sich pro Umdrehung ein Mal. Das heißt, pro Umdrehung bewegt sich der Kolben(9) von den oberen zu unteren Totpunkt und zurück wieder zu oberen Totpunkt.This procedure is repeated once per revolution. That is, per revolution, the piston (9) moves from top to bottom dead center and back again to top dead center.

Durch Verstellen mit der Verdichtung Stellvorrichtung Schnecke /Schneckenrad (13) der inneren Drehscheibe(3) zu der äußeren Drehscheibe(7) wird die Lage des Hebel(6) und dadurch das Verdichtungsverhältnis geändert.By adjusting the compression worm / worm wheel (13) of the inner turntable (3) to the outer turntable (7), the position of the lever (6) and thereby the compression ratio are changed.

Bei jeder halber Umdrehung dreht sich das Drehschiebeventil(ll) um ¼ Umdrehung (Bild 3). Dadurch erreicht man, bei einer vollen Umdrehung der Scheiben Ansaugen und Verdichten und bei der nächsten Umdrehung Arbeiten und Ausstoßen. So entstehen die 4 Takte (Bild 3) eines Verbrennung Motors.Every half turn, the rotary valve (ll) rotates ¼ turn (Fig. 3). This achieves, with a full rotation of the discs suction and compression and the next revolution work and ejection. This creates the 4 bars (Figure 3) of a combustion engine.

Das Drehschiebeventil (Bild 3) ist ein Zylinder, worin Unten die Gase durch Einlasskanal ein- und durch Auspuffkanal(Bild 6) ausströmen und durch oben seitlich angebrachte Rohrenden (Bild 3) in den Brennraum gelangen.The rotary slide valve (Fig. 3) is a cylinder in which the gases flow down through the inlet duct and out through the exhaust duct (Fig. 6) and into the combustion chamber through the top of the pipe (Fig. 3).

Oben auf dem Drehschiebeventil(11) sitzt der ¼ Ventildreh-Vorrichtung (Bild 5). Sie trifft bei einer vollen Umdrehung zweimal den, auf dem festen äußeren Ring angebrachten, zwei gegenüber liegenden Bolzen und dreht sich jedes mal um ¼ Umdrehung (Bild 4).At the top of the rotary slide valve (11) sits the ¼ valve turning device (Fig. 5). In one full turn, it hits twice the two opposing bolts mounted on the fixed outer ring and turns each ¼ turn each time (Figure 4).

So dreht sich bei einer vollen Umdrehung das Drehschiebeventil zweimal. (Bild 3)Thus, the rotary valve rotates twice in one full turn. (Picture 3)

Durch Verstellen der ¼ Ventildreh-Vorrichtung (Bild 5) wird Ventilöffnungszeit eingestellt.The valve opening time is set by adjusting the ¼ valve turning device (Fig. 5).

Einspritzdüse oder Zündkerze können beliebig platziert werden. Brennraum ist auch beliebig formbar.Injector or spark plug can be placed arbitrarily. Combustion chamber can also be shaped as desired.

Motoren mit mehreren Zylindern sind möglich, als Beispiel im Bild 6 ein zwei Zylinder Motor.Motors with several cylinders are possible, as an example in Figure 6 a two-cylinder engine.
