In order to produce a piston for an internal combustion engine and an internal combustion engine of said type having a piston according to the invention which, with little economic expenditure, provides an increase in performance and permits refined control, the present invention proposes a piston for an internal combustion engine which is characterized by having a second piston which is moveable relative to the first piston.

Description

Verbrennungsmotor und Kolben für Verbrennungsmotor Internal combustion engine and piston for internal combustion engine
Die vorliegende Erfindung betrifft einen Verbrennungsmotor sowie einen Kolben für einen Verbrennungsmotor.The present invention relates to an internal combustion engine and a piston for an internal combustion engine.
Im Bereich der Verbrennungsmotoren gibt es umfangreichen Stand der Technik und Verbrennungsmaschinen für jegliche Art von Brennstoff, Benzine, Diesel, Bioöle, Gas und dergleichen sind hinlänglich bekannt.In the field of internal combustion engines, there are many prior art and combustion engines for any kind of fuel, gasoline, diesel, bio-oils, gas and the like are well known.
Ein oder mehrere Kolben sind mit einer Pleuelstange an einer Kurbelwelle angelenkt und in einem Zylinder geführt. In dem Zylinder wird ein Luft-/Brennstoff- gemisch eingeführt und in Abhängigkeit von der Kolbenposition gezündet. Die Längsbewegung des Kolbens wird über die Pleuelstange auf die Kurbelwelle in eine Drehbewegung umgesetzt.One or more pistons are articulated to a crankshaft with a connecting rod and guided in a cylinder. In the cylinder, an air / fuel mixture is introduced and ignited in dependence on the piston position. The longitudinal movement of the piston is converted via the connecting rod to the crankshaft in a rotational movement.
Andere Motortypen wie beispielsweise Wankelmotoren, Flugkolbenmotoren oder dergleichen verwenden in einem Raum rotierende Kolben.Other types of engines such as Wankel engines, aircraft engines or the like use rotating pistons in a space.
Die Leistung von Verbrennungsmaschinen hängt ab von unterschiedlichen Dimensionierungsparametern und Leistungssteigerungen werden durch Abgasaufbereitung, Optimierung von LufWBrennstoffgemischen sowie Optimierungen in der Abgasführung, des Verbrennungsvorganges, der Steuerung und dergleichen.The performance of internal combustion engines depends on different dimensioning parameters and performance gains are improved by exhaust gas treatment, optimization of air / fuel mixtures as well as optimizations in the exhaust gas routing, the combustion process, the control and the like.
BESTÄT.©!^ 'SSStOPIIE Der vorliegenden Erfindung liegt die A u f g a b e zugrunde, einen Kolben für eine Verbrennungsmaschine sowie eine solche Verbrennungsmaschine mit einem erfindungsgemäßen Kolben vorzuschlagen, welcher mit geringem wirtschaftlichen Aufwand eine Leistungssteigerung erwirkt und eine verfeinerte Steuerung ermöglicht.CONFIRMATION ©! ^ 'SSStOPIIE The present invention is based on the object to propose a piston for an internal combustion engine and such an internal combustion engine with a piston according to the invention, which achieves an increase in performance with little economic effort and enables a more refined control.
Zur technischen L ö s u n g dieser Aufgabe wird ein Kolben für einen Verbrennungsmotor mit den Merkmalen des Patentanspruches 1 vorgeschlagen. Ein Verbrennungsmotor mit einem erfindungsgemäßen Kolben ergibt sich aus den Merkmalen des Patentanspruches 2. Weitere Vorteile und Merkmale sind in den Unteransprüchen gekennzeichnet.For the technical solution of this problem, a piston for an internal combustion engine with the features of claim 1 is proposed. An internal combustion engine with a piston according to the invention results from the features of claim 2. Further advantages and features are characterized in the subclaims.
Gemäß der Erfindung ist vorgesehen, in den Kolben einen weiteren Kolben zu führen. Durch diese Maßnahme ist es möglich, zusätzlich zu der Bewegung des Hauptkolbens auch den demgegenüber kleineren Kolben zu bewegen. Daraus ergibt sich eine verbesserte Nutzung im Rahmen der Energieumwandlung durch die Explosion eines Luft-/Brennstoffgemisches.According to the invention, it is provided to guide into the piston another piston. By this measure, it is possible to move in addition to the movement of the main piston and the opposite smaller piston. This results in an improved use in the context of energy conversion by the explosion of an air / fuel mixture.
Versuche und Berechnungen haben ergeben, daß sich Leistungssteigerungen bis über 40% ergeben können. Ein vorzugsweise realisierter Leistungssteigerungsbereich erbringt zusätzlich 25% gegenüber einem herkömmlich bekannten Kolben. Zum einen liegt dies an der Verbesserung des mechansichen Wirkungsgrades, zum anderen an einer besseren Verbrennungssteuerung.Trials and calculations have shown that increases in performance can exceed 40%. A preferably realized power increase range provides an additional 25% over a conventionally known piston. On the one hand, this is due to the improvement of the mechansichen efficiency, on the other hand to a better combustion control.
Ein mit einem erfindungsgemäßen Kolben versehener Verbrennungsmotor bietet entweder den Vorteil, daß er deutlich kleiner und leichter gebaut werden kann, ohne daß Leistungsverlust in Kauf genommen werden müssen, oder er kann bei gleichbleibender Baugröße mit einer Leistungssteigerung versehen werden.An internal combustion engine provided with a piston according to the invention either offers the advantage that it can be made significantly smaller and lighter without having to accept any loss of power, or it can be provided with an increase in power while maintaining the same size.
Darüber hinaus ergeben sich zusätzliche Möglichkeiten der Feinsteuerung, die sich beispielsweise äußerst günstig auf einen Verbrauch auswirken können.In addition, there are additional possibilities of fine control, which can for example have a very favorable effect on consumption.
Mit der Erfindung wird ein neuartiger Kolben vorgeschlagen, welcher mit geringem wirtschaftlichen Aufwand eine markante Leistungssteigerung ohne Volumenänderung gegenüber herkömmlichen Kolben bewirkt und darüber hinaus eine verbesserte Steuerungsmöglichkeit bietet. So kann die mechanische Anbindung des zusätzlichen Kolbens einstellbar ausgelegt werden, so dass variable Steuerzeiten/Volumina erreichbar sind.With the invention, a novel piston is proposed, which with little economic effort a significant increase in performance without Volume change over conventional piston causes and also provides an improved control option. Thus, the mechanical connection of the additional piston can be designed adjustable, so that variable timing / volumes can be achieved.
