Abstract
Description
Die Erfindung betrifft eine Getriebekinematik mit einem speziellen (quadropolaren) Getriebeelement, welches als Koppelglied innerhalb einer kinematischen Kette zu einem bestimmten, vorteilhaften Bewegungszyklus ausgezeichneter Partnerelemente führt.The Invention relates to a transmission kinematics with a special (quadrupole) Transmission element, which as a coupling member within a kinematic Chain to a certain, advantageous cycle of motion more excellent Partner elements leads.
Getriebeelemente, welche andere Funktionen als bei einem Standard-Getriebeelement des Standes der Technik (bestehend aus Kurbel, Pleuel, Kolben, Zylinder) ausüben, sind seit langem bekannt.Transmission elements which functions other than a standard transmission element of the prior art (consisting of crank, connecting rod, piston, cylinder) exercise are known for a long time.
Jüngeren Datums sind (Hub-) Getriebe, welche einen Kolben in einem Zylinder mittels eines Knickhebels auf seine Bahn führen. Ein Getriebe dieser Art ist nach der PCT-Anmeldung EP 88/00367 bekannt.Younger date are (Hub-) transmission, which means a piston in a cylinder lead a buckling lever on its path. A transmission of this kind is known from PCT application EP 88/00367.
Danach wird eine Steuerung der Kolbenbewegung vorgeschlagen, bei welcher die Verwendung von geteilten Pleueln, anstatt des sonst üblichen einteiligen Pleuels, vorgesehen ist. Hierdurch wird die Kinematik der Maschine verändert, mit der Maßgabe, dass der Kolben deutlich länger im Bereich des oberen Totpunktes (OT) verbleibt. Hierdurch soll der Verbrennungsablauf, die Abgasqualität und der Treibstoffverbrauch verbessert werden.After that a control of the piston movement is proposed in which the use of split connecting rods, instead of the usual ones one-piece connecting rod, is provided. This is the kinematics the machine changes, with the proviso that the piston much longer remains in the area of top dead center (TDC). This is intended the combustion process, the quality of the exhaust gas and the fuel consumption be improved.
Untersuchungen dieses Maschinentyps lieferten gleichwohl sehr unterschiedliche Ergebnisse. Einerseits konnten durch Betriebs-Messungen deutliche Verbrauchsreduzierungen und verbesserte Abgasqualität festgestellt werden, andererseits lieferten Prüfstand-Messungen hingegen keinerlei Verbesserungen (vgl. insbesondere Motortechnische Zeitschrift MTZ 49 von 1988).investigations However, this type of machine delivered very different Results. On the one hand, operational measurements made clear Consumption reductions and improved exhaust quality determined On the other hand, test bench measurements did not provide any Improvements (see in particular Motortechnische Zeitschrift MTZ 49 of 1988).
Ziel der Erfindung ist es, ein Getriebe für insbesondere Verbrennungskraftmaschinen zu entwickeln, welches deren effektiven Wirkungsgrad deutlich erhöht, indem ein nachfolgend näher beschriebenes (quadropolares) Getriebeelement eine Modifizierung des Bahnverlaufes, insbesondere eines Kolbens in einem Zylinder, bewirkt. Dabei wird erfindungsgemäß einerseits die Verweilzeit des Kolbens um den oberen Totpunkt (OT) deutlich erhöht und andererseits die Kraftübertragung innerhalb der kinematischen Kette vorteilhaft modifiziert.aim The invention is a transmission for particular internal combustion engines which significantly increases their effective efficiency by: one below described (quadrupole) transmission element a modification the trajectory, in particular a piston in a cylinder, causes. In this case, according to the invention, on the one hand, the residence time the piston around the top dead center (TDC) significantly increased and on the other hand the power transmission advantageously modified within the kinematic chain.
Dies ist mit dem Stand der Technik nicht zu erzielen.This can not be achieved with the prior art.
Ein
prinzipielles Ausführungsbeispiel
der Erfindung – insbesondere
für eine
Hubkolbenverbrennungskraftmaschine – ist in den nachfolgenden
Gezeigt
ist das prinzipielle, von den anderen Bauteilen separierte, quadropolare
Getriebeelement
Im
weiteren Kontext betrachtet (und erkenntlich gemacht an der Bezeichnung)
wird allerdings der Unterschied offenkundig: Die Punkte
Mit
Damit
ist dieses vorgestellte erfindungsgemäße Getriebe im Wesentlichen
komplett beschrieben und es wird ersichtlich, dass das quadropolare Getriebeelement
mit seinen beiden polaren Getriebepunkten
Insgesamt
gesehen lassen sich erfindungsgemäß vorteilhafte Geometrien und
Prozessparameter realisieren: Infolge der – im weiteren Bewegungsablauf
in Richtung unterer Totpunkt (UT) – Schwenkbewegung von
Es ist auch eine sehr effektive Benzindirekteinspritzung mit Selbstzündung möglich (HCSI = High Compression Self Ignition). Die Verbrennung veräuft erfindungsgemäß sehr viel schneller und intensiver, also insgesamt dynamischer, als üblich. Hieraus resultiert ein deutlich besseres Abgasverhalten und eine starke Reduzierung des Kraftstoffverbrauches.It is also a very effective gasoline direct injection with auto-ignition possible (HCSI = High Compression Self Ignition). The combustion runs very much according to the invention faster and more intense, more dynamic overall than usual. This results a significantly better exhaust behavior and a strong reduction of fuel consumption.
Darüber hinaus ergibt sich ein optimierter, vorteilhafterer Kraftfluß im erfindungsgemäßen Getriebe, welcher wiederum den effektiven Wirkungsgrad der vorgeschlagenen Kinematik deutlich erhöht.Furthermore results in an optimized, more advantageous power flow in the transmission according to the invention, which in turn the effective efficiency of the proposed Kinematics significantly increased.
Gezeigt
werden hier die Kolbenwege (um den OT) des Standes der Technik
Da bei räumlicher und zeitlicher Betrachtung des Geschehens nahezu eine vollständige Gleichraumverbrennung passiert, ist der thermische Wirkungsgrad dieses erfindungsgemäßen Prozesses entsprechend deutlich besser als beim Stand der Technik.There at spatial and temporal consideration of the event almost a complete equal space combustion happens, the thermal efficiency of this process according to the invention is corresponding significantly better than in the prior art.
Hier
ist eine Kombinationskraftmaschine zu sehen, welche als Kompressor
ein konventionelles Hubgetriebe
Erfindungsgemäßes Aggregat ist einfach und kostengünstig in der Herstellung sowie effektiv in seiner Wirkung. Der Treibstoffkonsum wird stark reduziert und die Abgasqualität um ein vielfaches verbessert.Inventive unit is easy and inexpensive in production as well as effective in its effect. The fuel consumption is greatly reduced and improves the exhaust gas quality many times over.
Neben Benzin, Diesel und anderen herkömmlichen Brennmitteln können auch minderwertigere, schwerentflammbare Stoffe oder Pflanzenöle bzw. Wasser (Gemische) zum Einsatz gelangen und insbesondere „selbstständig" bzw. „automatisch" gezündet werden. (Statt dem hier exemplarisch beschriebenen Ausführungsbeispiel lässt sich z. B. auch ein Schwenkkolben realisieren; mit den gleichen, günstigen Eigenschaften).Next Gasoline, diesel and other conventional Burning agents can also inferior, flame-retardant substances or vegetable oils or Water (mixtures) are used and in particular "autonomous" or "automatically" ignited. (Instead of the exemplary embodiment described here can be z. B. also realize a swing piston; with the same, cheap Properties).
