Description

Brennkraftmaschine Die Erfindung bezieht sich auf eine Brennkraftmaschine, die mit einem einstückig mit dem Kurbelgehäuase ausgebildeten Zylinderblock mit wassergekühlter Zylinderbüchse versehen ist und die einen auf den Zylinderblock aufgeschraubten Zylinderblock aufweist. Internal combustion engine The invention relates to an internal combustion engine, with a cylinder block formed in one piece with the crankcase water-cooled cylinder liner is provided and the one on the cylinder block Has screwed-on cylinder block.

Der Erfindung liegt die Aufgabe zugrunde, eine Brennkraftmaschine der beschriebenen Art einerseits derart auszubilden, daß die Zylinderbüchse frei von solchen Einflüssen bleibt, die einen Verzug verursachen könnten, andererseits die Brennkraftmaschine derart zu gestalten, daß in dem Zylinderkopf nur verhältnismäßig niedere Augen für die Befestigungsschrauben vorgesehen werden mdssen, um Freizügigkeit in der Verlegung der Gaswechselkanäle und in der Anordnung von Teilen, wie z.B.The invention is based on the object of an internal combustion engine of the type described on the one hand in such a way that the cylinder liner is free remains of such influences that could cause a delay, on the other hand to make the internal combustion engine such that in the cylinder head only relatively Lower eyes must be provided for the fastening screws to allow freedom of movement in the laying of the gas exchange ducts and in the arrangement of parts, e.g.

einer Einspritzdüse, Glthkerze o.dgl., zu gewinnen.An injection nozzle, glow plug or the like. To win.

Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Zylinderbüchse lediglich durch einen ringsum verlaufenden, gleichzeitig den Wasserraum nach untn abschließenden Flansch mit dem Zylinderblock verbunden ist und der Zylinderkopf von unten her an den Zylinderblock angeschraubt ist.The object is achieved according to the invention in that the Cylinder liner only through a circumferential, at the same time the water space the flange is connected to the cylinder block and the cylinder head from is screwed down to the cylinder block.

Durch die Erfindung wird erreicht, daß die Zylinderbüchse völlig verzugsfrei bleibt. Auch durch das Befestigen des Zylinderkopfs erleidet sie keinen Verzug. In Zylinderkopf selbst braucht bei der Anordnung der Gaswechselkanäle und von Teilen, wie z.B. einer Einspritzdüse, keine Rücksicht auf die Lage der Befestigungsschrauben genommen zu werden, da nur niedrige Augen für die Befestigungsschrauben erforderlich sind.The invention ensures that the cylinder liner is completely free of distortion remain. It is also not warped by fastening the cylinder head. In the cylinder head itself, when arranging the gas exchange ducts and parts, such as an injection nozzle, no consideration of the position of the fastening screws to be taken, as only low eyes are required for the fastening screws are.

In weiterer Ausgestaltung des Gegenstandes der Erfindung kann der die Zylinderbüchse mit den Zylinderblock verbindende Flansch etwa auf halber Höhe der Zylinderbüchse angeordnet sein, so daß beste Voraussetzungen für eine vorzugsfreie Einstellung der Zylinderbüchse gegeben sind.In a further embodiment of the subject matter of the invention, the the flange connecting the cylinder liner to the cylinder block about halfway up the cylinder liner be arranged, so that the best conditions for a preferential Adjustment of the cylinder liner are given.

Zum Einsetzen der Befestigungsschrauben für den Zylinderkopf kann der Zylinderblock an seinen oberen Ende einen ringsum verlaufenden Flansch für Bohrungen für diese Schrauben aufweisen.To insert the fastening screws for the cylinder head you can the cylinder block at its upper end has a flange running all around for bores for these screws.

In der Zeichnung ist der Gegenstand der Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the subject of the invention is in one embodiment shown.

Das Kurbelgehäuse 1 der gezeigten Brennkraftmaschine besteht aus einem Stück nit den Zylinderblock 2 und der Zylinderbüchse 3. Um die Zylinderbüchse 3 frei von Einflüssen zu halten, die einen Verzug verursachen könnten, besteht die Verbindung zwischen der Zylinderbüchse 3 und den Zylinderblock 2 lediglich aus den rings um die Zylinderbüchse 5 verlaufenden Flansch 4, der den in Richtung zum Zylinderkopf 5 hin offenen Wasserrau- 6 nach unten abschließt. Der Flansch 4 liegt etwa in halber Höhe der Zylinderbüchse 3.The crankcase 1 of the internal combustion engine shown consists of a Pieces with the cylinder block 2 and the cylinder liner 3. Around the cylinder liner 3 to keep it free from influences that could cause a delay Connection between the cylinder liner 3 and the cylinder block 2 only from the flange 4 running around cylinder liner 5, of the in Direction to the cylinder head 5 towards the open water pipe 6 closes down. Of the Flange 4 lies approximately halfway up the cylinder liner 3.

Der Zylinderkopf 5 ist von unten her an den Zylinderblock 2 angeschraubt. Zu diesem Zweck ist der Zylinderblock 2 an seinem oberen Ende mit einem ringsum verlaufenden Flansch 7 versehen, in dem Bohrungen 8 für die Zylinderkopfschrauben 9 angeordnet sind. Die Zylinderkopfschrauben 9 greifen in niedrige Augen 10 am Zylinderkopf 5 ein.The cylinder head 5 is screwed onto the cylinder block 2 from below. For this purpose, the cylinder block 2 is at its upper end with an all around extending flange 7 provided in the holes 8 for the cylinder head screws 9 are arranged. The cylinder head bolts 9 engage in low eyes 10 on the cylinder head 5 a.
