Abstract

Bei einem bekannten Vorschlag zur Hubraumvergrößerung werden die Zylinderabstände und die Zylinderdurchmesser vergrößert. Dies erfordert die Neukonstruktion aller wesentlichen Brennkraftmaschinenteile und macht darüberhinaus die Anpassung der vorhandenen Prioduktionsanlagen notwendig. Soll darüberhinaus die Brennkraftmaschine auch mit dem bisherigen Hubraum gebaut werden, müßen hierzu alle (bisherigen) Brennkraftmaschinenteile weitergebaut werden, so daß darüberhinaus eine große Teilevielfalt und entsprechende Bevorratung notwendig ist.In a known proposal to increase the displacement the cylinder distances and the cylinder diameter increased. This requires the redesign of all essential internal combustion engine parts and also makes adjustments to the existing ones Production facilities necessary. In addition, the internal combustion engine can also be built with the previous displacement, have to continue to build all (previous) internal combustion engine parts be, so that in addition a large variety of parts and appropriate stockpiling is necessary.

Erfindungsgemäß wird eine Hubraumvergrößerung realisiert, bei der die Teilevielfalt gering ist. Dies wird dadurch erreicht, daß der Zylinderkopf 2 für Brennkraftmaschinen mit verschiedenen Zylinderbohrungen in der Form verwendbar ist, daß der Zylinderkopf 2 für die Brennkraftmaschine mit der größten Bohrung bezüglich der Anordnung der Zylinderkopf-Befestigungen und der Gaswechselventile 4, 4a sowie der Durchmesser der Ventilteller 6 und der diese umgebenden Ventilsitzringe 7 ausgelegt ist und dabei die die Ventilteller 6 bis in den Zylinderrandbereich des mit dem Brennraum zusammenwirkenden Teils des Zylinderkopfs 2 reichen, und wobei der gleiche Zylinderkopf 2 mit Ventilsitzringen 7a bestückbar ist, die eine an eine geringere Bohrung einer weiteren Brennkraftmaschine angepaßte Reduzierung des Ventiltellerdurchmessers bewirken.

Figure 00000001
According to the invention, an increase in displacement is realized in which the number of parts is small. This is achieved in that the cylinder head 2 can be used for internal combustion engines with different cylinder bores in the form that the cylinder head 2 for the internal combustion engine with the largest bore with regard to the arrangement of the cylinder head fastenings and the gas exchange valves 4, 4a and the diameter of the valve plate 6 and the valve seat rings 7 surrounding it are designed and which extend the valve plates 6 into the cylinder edge region of the part of the cylinder head 2 which interacts with the combustion chamber, and wherein the same cylinder head 2 can be equipped with valve seat rings 7a which are adapted to a smaller bore of another internal combustion engine cause adapted reduction of the valve plate diameter.
