Abstract
Description
Stand der TechnikState of the art
Bei Hubkolben Motoren muss den Kolben in den Endstellungen (u. T.; o. T.), d. h. am Ende jedes Arbeitstakts, immer die gesamte kinetische Energie entzogen und anschließend wieder zugeführt werden. In der unter Aktenzeichen 10 2010 006 428.9 registrierten Patentanmeldung ist der bisherige Stand der Technik und es sind Triebwerke von Viertakt Verbrennungsmotoren beschrieben, bei denen nicht nur den Kolben, sondern weiteren Teilen ihre kinetische Energie bis zum Erreichen der Endstellungen entzogen und anschließend wieder zugeführt werden muss. Diese Energie Austauschvorgänge belasten immer mehrere Lager, und bewirken entsprechende Reibungsverluste, weil nur ein Kolben seine kinetische Energie direkt an das zu verdichtende Frischgas abgeben und anschließend vom expandierenden Abgas erhalten kann. Ein besserer Wirkungsgrad erfordert deshalb, beim Energieaustausch weniger oder gar keine Lager zu belasten.For reciprocating engines, the piston must be in the end positions (and T .; H. at the end of each working cycle, always withdrawing all the kinetic energy and then returning it. In patent application 10 2010 006 428.9 registered patent application is the prior art and there are engines of four-stroke internal combustion engines described in which not only the piston, but other parts their kinetic energy must be withdrawn until reaching the end positions and then fed again , These energy exchanges always load several bearings, and cause corresponding friction losses, because only one piston can deliver its kinetic energy directly to the fresh gas to be compressed and then obtain from the expanding exhaust gas. A better efficiency therefore requires less or no bearing during the energy exchange.
Die Kolben müssen translatorisch hin und her bewegt werden und sind deshalb in den Zylindern gleit gelagert. Sind sie an Kreuzköpfen (Gleitsteinen) befestigt, dann sind die Kreuzköpfe auf Gleitschienen gleit gelagert.The pistons must be moved back and forth translationally and are therefore slidably mounted in the cylinders. Are they attached to crossheads (sliding blocks), then the crossheads are slidably mounted on slide rails.
Das Problem Massenausgleich ist zwar auf unterschiedlichste Weise, aber nie vollständig, gelöst worden.The problem of mass balance has been solved in a variety of ways, but never completely.
Sinn und Zweck der vorliegenden Erfindung ist es, einen Viertakt Verbrennungsmotor bekannt zu machen, der so ausgeführt ist, dass die Kolben an einem Kreuzkopf translatorisch hin und her bewegt werden. Der Kreuzkopf gleitet aber nicht auf einer Führungsschiene sondern rollt auf ihr,
Die Zwillings Vierzylinder Bauweise mit acht Zylindern, in einer oder zwei zueinander senkrechten Ebenen, eröffnet die Möglichkeit, in zwei zur Symmetrielinie des Kreuzkopfes symmetrischen Zylindern denselben Arbeitstakt ablaufen zu lassen. Dadurch wird erreicht, dass die Wirkungslinie der Gaskräfte in allen Stellungen und Arbeitstakten immer die Symmetrielinie des Kreuzkopfes ist, auf der auch der Mittelpunkt des Verbindungsdrehgelenks liegt.The twin four-cylinder design with eight cylinders, in one or two mutually perpendicular planes, opens the possibility to run in two symmetrical to the symmetry line of the crosshead cylinders the same power stroke. This ensures that the line of action of the gas forces in all positions and power strokes is always the line of symmetry of the crosshead, on which also lies the center of the joint joint.
Werden zwei derartige Kreuzköpfe gleicher Masse ineinandergeschachtelt und gegensinnig bewegt, dann wird der vollständige Massenausgleich erreicht, denn der Gesamtschwerpunkt ist ein fester Punkt.If two such cross heads of the same mass are nested and moved in opposite directions, then the full mass balance is achieved because the overall center of gravity is a fixed point.
In
Die von den Gaskräften an den sich bewegenden Kolben verrichtete mechanische Arbeit wird mit Hilfe dieser Koppelgetriebe als Drehmoment auf die Hauptwelle übertragen und kann zum Antreiben eines Automobils oder Arbeitsmaschinen verwendet werden.The mechanical work done by the gas forces on the moving pistons is transmitted to the main shaft as torque by means of these coupling gears and can be used to drive an automobile or work machines.
Vorteile:Advantages:
- 1. Der Kreuzkopf, also alle sich wechselsinnig bewegenden Teile, gibt in beiden Endstellungen (o. T. und u. T.) seine gesamte kinetische Energie direkt an das zu verdichtende Frischgas ab ohne ein Lager zu belasten. Der Energieaustausch erfolgt mit geringst möglichen Reibungsverlusten.1. The crosshead, ie all parts moving in the opposite direction, releases its entire kinetic energy directly into the fresh gas to be compressed without stressing a bearing in both end positions (above T. and below). The energy exchange takes place with the least possible friction losses.
- 2. Die mechanische Arbeit der Kräfte des expandierenden Gases ändert teilweise direkt die kinetische Energie des Kreuzkopfes, also aller sich wechselsinnig bewegenden Teile. Die Lager von Hauptwelle und Koppelgetriebe sind entlastet.2. The mechanical work of the forces of the expanding gas partly directly changes the kinetic energy of the crosshead, that is, all parts moving in the same direction. The bearings of main shaft and coupling gear are relieved.
- 3. Die Kräfte des zu verdichtenden und expandierenden Gases haben immer dieselbe Wirkungslinie. Es treten keine Drehmomente auf.3. The forces of the gas to be compressed and expanding always have the same line of action. There are no torques.
- 4. Die Kolben stützen sich nicht mehr an der Zylinderwand ab d. h. die bisher durch das Gleiten der Kolben an der Zylinderwand verursachten Reibverluste entfallen.4. The pistons are no longer supported on the cylinder wall d. H. the previously caused by the sliding of the piston on the cylinder wall friction losses omitted.
- 5. Weil der Anlagewechsel der Kolben entfällt können die Zylinderlaufbüchsen keramisiert werden. Die Energieverluste durch Wärmeleitung sind kleiner.5. Because the system change of the piston is eliminated, the cylinder liners can be ceramized. The energy losses due to heat conduction are smaller.
- 6. Ein Kolbenring genügt, den Brennraum abzudichten. Reibungsverluste sind geringer.6. A piston ring is sufficient to seal the combustion chamber. Frictional losses are lower.
- 7. Die Bauweise erfordert die geringste Zahl von Kugel-, Rollen-, Wälz- oder Nadellagern.7. The design requires the least number of ball, roller, roller or needle bearings.
- 8. Die Motoren benötigen keine Umlaufschmierung mehr.8. The motors no longer need circulation lubrication.
- 9. Die Kühlung der Zylinderlaufbuchsen mit einem besonderen Kühlmittel kann entfallen.9. The cooling of the cylinder liners with a special coolant can be omitted.
- 10. Das beliebig große Hub/Bohrungsverhältnis eröffnet die Möglichkeit, nur einen Teil der Zylinderfüllung so hoch zu verdichten, dass jeder Treibstoff sicher zündet. Damit besteht die Chance, das Abgas weiter zu entspannen und abzukühlen. Ergibt geringere Abgasverluste.10. The arbitrarily large stroke / bore ratio opens the possibility to compress only a portion of the cylinder filling so high that each fuel safely ignites. This gives the opportunity to further relax and cool the exhaust gas. Results in lower exhaust gas losses.
