Abstract

Die Erfindung betrifft einen Zylinderkopf (1), der an einer Montage-Stirnseite (9) mit einem Zylinderblock verbindbar ist, mit einem zumindest teilweise im Zylinderkopf (1) integrierten Kühlmittelmantel (2) für eine Brennkraftmaschine mit mindestens zwei Zylindern, bei dem jeder Zylinder mindestens eine Auslaßöffnung (3a, 3b) zum Abführen der Abgase aus dem Zylinder aufweist, wobei
- sich an jede Auslaßöffnung (3a, 3b) eine Abgasleitung (4a, 4b) anschließt,
- die Abgasleitungen (4a, 4b) von mindestens zwei Zylindern innerhalb des Zylinderkopfes (1) zu einer Gesamtabgasleitung (6) zusammenführen, und
- der Kühlmittelmantel (2) einen unteren Kühlmittelmantel (2a), der zwischen den Abgasleitungen (4a, 4b, 5, 6) und der Montage-Stirnseite (9) des Zylinderkopfes (1) angeordnet ist, und einen oberen Kühlmittelmantel (2b), der auf der dem unteren Kühlmittelmantel (2a) gegenüberliegenden Seite der Abgasleitungen (4a, 4b, 5, 6) angeordnet ist, aufweist.The invention relates to a cylinder head (1) which can be connected to a cylinder block at an assembly end face (9) with an at least partially integrated coolant jacket (2) in the cylinder head (1) for an internal combustion engine having at least two cylinders, in which each cylinder at least one outlet opening (3a, 3b) for discharging the exhaust gases from the cylinder, wherein
- An exhaust pipe (4a, 4b) connects to each outlet opening (3a, 3b),
- Merge the exhaust pipes (4a, 4b) of at least two cylinders within the cylinder head (1) to an overall exhaust line (6), and
- The coolant jacket (2) has a lower coolant jacket (2a) which is arranged between the exhaust pipes (4a, 4b, 5, 6) and the mounting end face (9) of the cylinder head (1), and an upper coolant jacket (2b), which is arranged on the side of the exhaust gas lines (4a, 4b, 5, 6) opposite the lower coolant jacket (2a).

Es soll ein flüssigkeitsgekühlter Zylinderkopf (1) der gattungsbildenden Art bereitgestellt werden, der über eine optimierte Kühlung verfügt.It is a liquid-cooled cylinder head (1) of the generic type are provided, which has an optimized cooling.

Gelöst wird diese Aufgabe durch einen Zylinderkopf (1) der oben genannten Art, der dadurch gekennzeichnet ist, daß beabstandet zu den Abgasleitungen (4a, 4b, 5, 6) in einer Außenwandung (10) des Zylinderkopfes (1), aus der die Gesamtabgasleitung (6) austritt, mindestens eine Verbindung (7) zwischen dem unteren Kühlmittelmantel (2a) und dem oberen Kühlmittelmantel (2b) vorgesehen ist, die dem Durchtritt von Kühlmittel dient, wobei die mindestens eine Verbindung (7) benachbart zu dem Bereich (8) angeordnet ist, in dem die Abgasleitungen (4a, 4b, 5) zu der Gesamtabgasleitung (6) zusammenführen.

Figure imgaf001
This object is achieved by a cylinder head (1) of the type mentioned above, which is characterized in that spaced from the exhaust pipes (4a, 4b, 5, 6) in an outer wall (10) of the cylinder head (1) from which the entire exhaust line (6), at least one connection (7) is provided between the lower coolant jacket (2a) and the upper coolant jacket (2b), which serves for the passage of coolant, the at least one connection (7) adjacent to the region (8). is arranged, in which the exhaust pipes (4a, 4b, 5) merge to the total exhaust gas line (6).
