Description

Die Erfindung bezieht sich auf einen Zylinder zur Hubraumerhöhung für einen Verbrennungsmotor der am Zylinderkopf seitigem Ende im Bereich des Feuersteges des Kolbens in der oberen Totpunktlage, durch einen eingesetzten Ring im Durchmesser verkleinert ist.The invention relates to a cylinder for increasing the displacement of an internal combustion engine of the cylinder head end in the region of the top land of the piston in the top dead center, is reduced by an inserted ring in diameter.

Bekanntermaßen gibt es bei einer Hubraumerhöhung folgende Möglichkeiten:

  • – Austausch des Zylinderkopfes;
  • – Bearbeitung des Zylinderkopfes.
As is known, there are the following possibilities with a displacement increase:
  • - Replacement of the cylinder head;
  • - Machining of the cylinder head.

Nachteilig bei diesen Hubraumerhöhungen ist, dass hier eine Bearbeitung bzw. Austausch des Zylinderkopfes unausweichlich ist. Hohe Kosten für die Bearbeitung des Zylinderkopfes bzw. noch höhere Kosten für den Austausch des Zylinderkopfes stehen an.A disadvantage of these increases in capacity is that here a processing or replacement of the cylinder head is inevitable. High costs for the machining of the cylinder head or even higher costs for the replacement of the cylinder head are on.

Aufgabe der Erfindung ist es nun, einen Zylinder zur Hubraumerhöhung für einen Verbrennungsmotor bereitzustellen, unter Beibehaltung des originalen Brennraumes bzw. des originalen Zylinderkopfes.The object of the invention is now to provide a cylinder for increasing the displacement of an internal combustion engine, while maintaining the original combustion chamber or the original cylinder head.

Die vorstehend genannte Aufgabe wird dadurch gelöst, dass im oberen Zylinderbereich am Übergang zum Zylinderkopf ein konisch umlaufend ausgebildeter Ring (High Turbulence Ring) eingepresst wird. D. h., dass der Durchmesser an der oberen Kante des Zylinders verengt und an den bestehenden Zylinderkopf angepasst wird.The above object is achieved in that in the upper cylinder area at the transition to the cylinder head, a conically circumferentially formed ring (High Turbulence Ring) is pressed. That is, the diameter at the upper edge of the cylinder is narrowed and adjusted to the existing cylinder head.

Durch die konische Anordnung des Ringes wird im Verdichtungsvorgang das in diesem Randbereich befindliche Luft-Kraftstoff-Gemisch mit hoher Geschwindigkeit herausgequetscht, sorgt für eine bessere Gasführung und damit eine gute Verbrennung des Gemisches.Due to the conical arrangement of the ring, the air-fuel mixture located in this edge region is squeezed out at high speed in the compression process, ensures better gas flow and thus good combustion of the mixture.

Dieser Ring kann sowohl schräg als auch gerundet sein. Dieser reduziert den Durchmesser entsprechend dem Zylinderkopf.This ring can be both oblique and rounded. This reduces the diameter according to the cylinder head.

Hierzu ist es vorteilhaft, den eingepressten Ring aus einem Hochhitze beständigen und/oder verschleißfesten Werkstoff anzufertigen.For this purpose, it is advantageous to make the pressed-in ring from a high-temperature resistant and / or wear-resistant material.

Ferner ist es vorteilhaft, dass der Winkel des konischen Ringes abhängig von der Form des Brennraumes und der Neukonstruktion des Kolbens ist.Furthermore, it is advantageous that the angle of the conical ring is dependent on the shape of the combustion chamber and the redesign of the piston.

Diese erfindungsgemäße Gestaltung des Zylinders erlaubt auch die Verwendung für alle Otto- und Dieselmotoren.This inventive design of the cylinder also allows use for all gasoline and diesel engines.

Durch die erfindungsgemäße Lösung ergeben sich folgende Vorteile:

  • – Kostenreduzierung;
  • – Zylinderkopf kann weiter verwendet werden, muss also nicht ausgetauscht werden;
  • – Strömungsoptimierung;
  • – Höhere Verdichtung des Kraftstoff-Luft-Gemisches;
  • – Bessere Gasführung;
  • – effizientere Verbrennung;
  • – folglich weniger Kraftstoffverbrauch
The solution according to the invention affords the following advantages:
  • - cost reduction;
  • - Cylinder head can continue to be used, so it does not need to be replaced;
  • - flow optimization;
  • - higher compression of the fuel-air mixture;
  • - Better gas guidance;
  • - more efficient combustion;
  • - consequently less fuel consumption

Die Erfindung wird anhand der nachfolgenden Beschreibung und der Zeichnung näher erläutert:
In der Zeichnung ist ein Schnitt durch die Brennkraftmaschine im Bereich eines Zylinders (4) mit Kolben (6) dargestellt, der sich in der oberen Totpunktlage befindet. Am Übergang zum Zylinderkopf (2, 2a) ist ein Ring (7, 7a), der konisch verläuft eingesetzt, der mit der Zylinderdichtfläche (9, 9a) des Zylinderkopfes (2, 2a) abschließt. Der Ring (7, 7a) aus einem verschleißfesten Werkstoff oder einem Hochhitze beständigen Stahl ist in den Zylinder (4, 4a) eingepresst. Der Innendurchmesser des Ringes (7, 7a) verjüngt sich vom Zylinderdurchmesser ausgehend zum Zylinderkopf (2, 2a); das entspricht der Mantellinie eines Kegels. Wie die Zeichnung zeigt, ergibt sich damit zwischen dem Feuersteg (8, 8a) des Kolbens (6) und dem Zylinder (4, 4a) eine optimale Verdichtung des Luft-Kraftstoff-Gemisches.The invention will be explained in more detail with reference to the following description and the drawing:
In the drawing, a section through the internal combustion engine in the region of a cylinder ( 4 ) with piston ( 6 ), which is in the top dead center position. At the transition to the cylinder head ( 2 . 2a ) is a ring ( 7 . 7a ), which runs conical, with the cylinder sealing surface ( 9 . 9a ) of the cylinder head ( 2 . 2a ) completes. The ring ( 7 . 7a ) made of a wear-resistant material or a high-temperature resistant steel is in the cylinder ( 4 . 4a ). The inner diameter of the ring ( 7 . 7a ) tapers from the cylinder diameter starting to the cylinder head ( 2 . 2a ); this corresponds to the generatrix of a cone. As the drawing shows, this results between the flank ( 8th . 8a ) of the piston ( 6 ) and the cylinder ( 4 . 4a ) an optimal compression of the air-fuel mixture.
