Ein derartiger Zylinderkopf ist beispielsweise aus der DE 38 38 953 C2 bekannt, wobei die Querwände zwischen diametralen Schraubenpfeifen den Kühlmittelraum der Höhe nach durchsetzen bis zur eben verlaufenden Deckwand und weiter an den Querwänden in den Verbindungsebenen querab benachbarter Schachtrohre vor den Schachtrohren jeweils endende Längswände vorgesehen sind, die bei einer Querdurchströmung des Zylinderkopfes der Ablenkung des Kühlmittels in Richtung der Schachtrohre und der angrenzenden Bereiche des Zylinderkopfbodens dienen, wobei an diesem zusätzliche Führungsrippen angeordnet sind. Such a cylinder head is known for example from DE 38 38 953 C2, the transverse walls between diametrical screw pipes the coolant space Push through in height to the level wall and continue to the Transverse walls in the connecting levels of adjacent shaft pipes in front of the Shaft pipes each have longitudinal walls that end with a cross-flow the cylinder head of the deflection of the coolant in the direction of Manhole pipes and the adjacent areas of the cylinder head base serve, whereby are arranged on this additional guide ribs.

Nachteilig an diesem bekannten Zylinderkopf ist die aufwendige Gussgestaltung sowie die großräumige Kühlmittelraum-Ausbildung.The disadvantage of this known cylinder head is the complex casting design as well as the large-scale coolant room training.

Der Erfindung liegt die Aufgabe zugrunde, einen gattungsgemäßen Zylinderkopf gusstechnisch einfacher auszugestalten bei hoher Steifigkeit und gezielter Kühlmittelführung mindestens in Querströmung.The invention has for its object a generic cylinder head Easier to design in terms of casting technology with high rigidity and targeted coolant flow at least in cross flow.

Diese Aufgabe ist mit dem Patentanspruch 1 dadurch gelöst, dass in der Deckwand zwischen diametralen Schraubenpfeifen und jeweils querab benachbarten Schachtrohren eine Mulde angeordnet ist, die mittels einer Querwand zwischen den diametralen Schraubenpfeifen mit dem Zylinderkopfboden in Verbindung steht, wobei von der Querwand in Richtung Deckwand ansteigend ausgebildete Wandabschnitte der Mulde als Strömungsleitflächen dienen.This object is achieved with claim 1 in that in the top wall between diametrical screw pipes and in each case across adjacent Well pipes a trough is arranged by means of a transverse wall between the diametrical screw pipes is connected to the cylinder head base, whereby Wall sections rising from the transverse wall towards the top wall the trough serve as flow control surfaces.

Mit der Erfindung ist in vorteilhafter Weise bei gusstechnisch einfacherer Ausgestaltung mittels der mit dem Zylinderkopfboden über Querwände verbundenen Mulden ein besonders steifer Zylinderkopf erzielt, wobei in weiterer vorteilhafter Weise mit dem Fortfall gesonderter Leitrippen zur Strömungsbeeinflussung eine bessere Entlüftung des Zylinderkopfes erzielt ist.The invention is advantageous with a simpler design in terms of casting technology by means of the troughs connected to the cylinder head floor via transverse walls achieved a particularly rigid cylinder head, in a further advantageous manner with the elimination of separate guide ribs to influence the flow, a better one Venting of the cylinder head is achieved.

Gemäß der Erfindung können die Mulden für einen Zylinderkopf als gesonderte Bauteile ausgebildet sein, sie sind jedoch in Weiterbildung der Erfindung vorzugsweise mittels Gussausbildung einstückig angeordnet, wobei eine Mulde sich - in Draufsicht gesehen - von jeder Schraubenpfeife aus in Richtung einer Verbindungsebene der querab benachbarten Schachtrohre erweitert und als eine zu den Schachtrohren gerichtete Strömungslenkung dient.According to the invention, the troughs for a cylinder head as separate Components are formed, but they are preferred in a development of the invention arranged in one piece by means of cast formation, with a trough - in Seen from above - from each screw pipe towards a connection plane of the adjacent shaft pipes extended and as one to the Shaft pipes directed flow control is used.

Damit wird die Umlaufmenge an Schmieröl klein gehalten und eine unnötige Aufheizung vermieden.For the discharge of those coming out of the control housing of the cylinder head into a trough Lubricating oil is provided according to a further proposal that the Trough is connected to the oil drainage channel via a separate channel, in a further embodiment, an inlet opening of the separate channel in the Trough is arranged according to the installation position of the cylinder head. So that will the circulating amount of lubricating oil is kept small and unnecessary heating is avoided.

Schließlich ist mit der Erfindung eine zusätzliche Aussteifung des Zylinderkopfes dadurch erzielt, dass die Mulde entlang ihres Öffnungsrandes mit einem über die Deckwand vorspringend angeordneten Versteifungssteg versehen ist. Mit dieser Anordnung sind in gusstechnisch vorteilhafter Weise quer zum längsgerichteten Zylinderkopf zwischen Schraubenpfeifen verlaufende Versteifungsstege erzielt, die gemäß der erfindungsgemäßen Muldenform V-förmig über den Zylinderkopf hinweg verlaufen und somit diesen sowohl in Quer- als auch in Längsrichtung zusätzlich aussteifen.Finally, the invention provides additional stiffening of the cylinder head achieved in that the trough along its opening edge with a over the Cover wall is provided protruding stiffening web.

Weiter ist der Zylinderkopf 1 derart gestaltet, dass vom Zylinderkopfboden 3 aus den Kühlmittelraum 6 und die Deckwand 4 durchsetzende Schraubenpfeifen 7 sowie Ölablaufkanäle 8 und etwa zylindermittig angeordnete Schachtrohre 9 für Zündkerzen oder Einspritzdüsen vorgesehen sind. Weiter ist der Kühlmittelraum 6 mittels Querwänden 10 zwischen diametralen Schraubenpfeifen 7 unterteilt.A liquid-cooled cross-flow cylinder head 1 for an internal combustion engine, not shown with cylinders arranged in series includes an integrated control housing 2 and one between a cylinder head base 3 and a control housing side Top wall 4 of side walls 5 limited coolant space 6. Next is the cylinder head 1 is designed in such a way that the coolant chamber extends from the cylinder head base 3 6 and the top wall 4 penetrating screw pipes 7 and oil drainage channels 8 and shaft pipes 9 arranged approximately in the center of the cylinder for spark plugs or injectors are provided.

Zur gusstechnisch vereinfachten Ausgestaltung des Zylinderkopfes 1 mit hoher Steifigkeit und gezielter Kühlmittelführung wird vorgeschlagen, dass in der Deckwand 4 zwischen diametralen Schraubenpfeifen 7 und jeweils querab benachbarten Schachtrohren 9 eine Mulde 11 angeordnet ist, die mittels einer Querwand 10 zwischen den diametralen Schraubenpfeifen 7 und dem Zylinderkopfboden 3 in Verbindung steht, wobei von der Querwand 10 in Richtung Deckwand 4 ansteigend ausgebildete Wandabschnitte 11' und 11" der Mulde 11 als Strömungsleitflächen dienen.To simplify the design of the cylinder head 1 with high casting technology Rigidity and targeted coolant flow is suggested in the top wall 4 between diametrical screw pipes 7 and adjacent to each other transversely Shaft pipes 9 a trough 11 is arranged, which by means of a transverse wall 10 between the diametrical screw pipes 7 and the cylinder head base 3 in connection is formed, rising from the transverse wall 10 towards the top wall 4 Wall sections 11 'and 11 "of the trough 11 serve as flow guide surfaces.

Wie aus den Figuren 1 und 2 ersichtlich, ist die Mulde 11 mittels Gussausbildung einstückig im Zylinderkopf 1 angeordnet, wobei die Mulde 11 sich - in Draufsicht gesehen - von jeder Schraubenpfeife 7 aus in Richtung einer Verbindungsebene 12 - Figur 3 - der querab benachbarten Schachtrohre 9 erweitert und als eine zu den Schachtrohren 9 gerichtete Strömungslenkung dient.As can be seen from Figures 1 and 2, the trough 11 is by means of cast formation arranged in one piece in the cylinder head 1, the trough 11 itself - in plan view seen - from each screw pipe 7 in the direction of a connecting plane 12 - Figure 3 - of the adjacent shaft pipes 9 expanded and as one of the Manhole pipes 9 directional flow control is used.

Um das aus dem Steuergehäuse 2 in die Mulde 11 gelangende Schmieröl sicher abzuführen, steht die Mulde 11 über einen gesonderten Kanal 13 mit dem Ölablaufkanal 8 bzw. 8' in Verbindung.To ensure that the lubricating oil coming from the control housing 2 into the trough 11 to discharge, the trough 11 is via a separate channel 13 with the oil drain channel 8 or 8 'in connection.
