Abstract
Description
Die Erfindung betrifft einen Zylinderkopf einer flüssigkeitsgekühlten Brennkraftmaschine mit den Merkmalen des Oberbegriffs des Anspruches 1.The The invention relates to a cylinder head of a liquid-cooled internal combustion engine with the features of the preamble of claim 1.
Aus
der
Aufgabe der Erfindung ist es demgegenüber einen flüssigkeitsgekühlten Zylinderkopf für eine Brennkraftmaschine bereitzustellen, der für höchste Zünddrücke im Brennraum unterhalb des Zylinderkopfbodens und für hohe Temperaturbelastung gleichermaßen geeignet ist.task In contrast, the invention is a liquid cooled cylinder head for an internal combustion engine to provide for highest ignition pressures in the combustion chamber below the cylinder head floor and for high temperature load equally suitable is.
Diese Aufgabe wird durch einen flüssigkeitsgekühlten Zylinderkopf mit den Merkmalen des Anspruches 1 gelöst. Ein flüssigkeitsgekühlter Zylinderkopf einer Brennkraftmaschine mit einem Schacht für eine Einspritzdüse oder eine Zündkerze und mehreren Gaswechselkanälen (Einlass-, Auslasskanal), die vom Zylinderkopfboden durch den Kühlmittelraum zu Seitenwänden führen, ist mit mehreren Versteifungsrippen im Kühlmittelraum ausgestattet, die radial ausgerichtet um die Gaswechselkanäle herum angeordnet sind. Mittels dieser Rippen erfolgt eine gute Abstützung des Zylinderkopfbodens an den Gaswechselkanälen, die ihrerseits an den Seitenwänden des Zylinderkopfes und über die Ventilführungen an einem Zylinderkopfdach abgestützt sind. Durch die Vielzahl von Versteifungsrippen wird eine gleichmäßige Abstützung erreicht. Gleichzeitig wird durch die Vielzahl von Versteifungsrippen der Kühlmittelstrom im Zylinderkopf verwirbelt, was für einen guten Wärmeübergang vom Zylinderkopf in das Kühlmittel förderlich ist. Auf diese Weise wird ein Verformen des Zylinderkopfbodens bei hohen Verbrennungsdrücken und -temperaturen und damit ein vorzeitiges Versagen des Zylinderkopfes verhindert.These Task is by a liquid-cooled cylinder head solved with the features of claim 1. A liquid-cooled cylinder head an internal combustion engine with a shaft for an injection nozzle or a spark plug and several gas exchange channels (Inlet, exhaust duct) leading from the cylinder head floor through the coolant space to sidewalls to lead, is equipped with several stiffening ribs in the coolant chamber, which are arranged radially aligned around the gas exchange channels around. through This ribs is a good support of the cylinder head floor at the gas exchange channels, which in turn on the side walls of the cylinder head and over the valve guides supported on a cylinder head roof are. Due to the large number of stiffening ribs a uniform support is achieved. At the same time is due to the large number of stiffening ribs of Coolant flow in the Cylinder head swirls, what for a good heat transfer from the cylinder head into the coolant conducive is. In this way, a deformation of the cylinder head floor is at high combustion pressures and Temperatures and thus premature failure of the cylinder head prevented.
In einer Ausgestaltung der Erfindung erstrecken sich die Versteifungsrippen bis zu einem Zylinderkopfdach als oberer Begrenzung des Kühlmittelraumes. Durch eine zusätzliche Abstützung der Versteifungsrippen am Zylinderkopfdach werden der Zylinderkopfboden und die Gaswechselkanäle nochmals besser abgestützt und versteift.In According to one embodiment of the invention, the stiffening ribs extend up to a cylinder head roof as the upper boundary of the coolant space. By an additional support The stiffening ribs on the cylinder head roof become the cylinder head floor and the gas exchange channels better supported again and stiffened.
In einer weiteren Ausgestaltung der Erfindung erstreckt sich eine Versteifungsrippe bis zu einer Verbindungswand zwischen zwei Schraubenpfeifen. Wenn in einem Zylinderkopf einer Brennkraftmaschine eine eindeutige Querströmung des Kühlmittels erwünscht ist, ist es von Vorteil zwischen zwei sich gegenüberliegenden Schraubenpfeifen für Zylinderkopfschrauben eine Verbindungswand vorzusehen. In diesem Falle ist es besonders vorteilhaft, wenn die Versteifungsrippen, die von den Gaswechselkanälen ausgehen, bis zu dieser Verbindungswand geführt ist. Dadurch wird die Steifigkeit des Zylinderkopfes erhöht und es wird gleichzeitig ein Anströmen des Zylinderkopfbodens und der Gaswechselkanäle durch das Kühlmittel erreicht.In In another embodiment of the invention, a stiffening rib extends up to a connecting wall between two screw pipes. If in a cylinder head of an internal combustion engine, a clear cross-flow of refrigerant he wishes is, it is beneficial between two opposite screw pipes for cylinder head bolts to provide a connecting wall. In this case it is special advantageous when the stiffening ribs emanating from the gas exchange channels, is led to this connection wall. This will increase the stiffness of the cylinder head increased and it is at the same time an influx of the cylinder head floor and the gas exchange channels through the coolant reached.
In einer weiteren Ausgestaltung der Erfindung weist eine Versteifungsrippe einen Kühlmitteldurchlass auf. Um den Kühlmittelstrom gezielt in Richtung Zylinderkopfboden und Gaswechselkanäle umzuleiten, ist es von Vorteil die Versteifungsrippe mit einem Durchlass für das Kühlmittel zu versehen. Dies kann direkt beim Gießen des Zylinderkopfes erfolgen oder es wird bei der Zylinderkopfbearbeitung nachträglich z.B. eine Bohrung angebracht.In A further embodiment of the invention has a stiffening rib a coolant passage on. To the coolant flow to redirect towards the cylinder head floor and gas exchange channels it is advantageous the stiffening rib with a passage for the coolant to provide. This can be done directly when casting the cylinder head or it is retrofitted during cylinder head machining, e.g. a hole attached.
In einer weiteren Ausgestaltung der Erfindung bilden jeweils eine Versteifungsrippe benachbarter Einlass- und/oder Auslasskanäle eine zusammenhängende Rippe. Genauso, wie zwischen einem Gaswechselkanal und einer Verbindungswand eine Versteifungsrippe verläuft, ist es möglich zwischen zwei benachbarten Gaswechselkanälen durchgehende Versteifungsrippen anzuordnen, um dadurch die Steifigkeit des Zylinderkopfes nochmals zu erhöhen. Dabei ist es unerheblich, ob es Einlass- oder Auslasskanäle sind, zwischen denen sich die Versteifungsrippe erstreckt.In a further embodiment of the invention each form a stiffening rib adjacent inlet and / or outlet channels a contiguous rib. Just as between a gas exchange channel and a connecting wall a stiffening rib runs, Is it possible between two adjacent gas exchange channels continuous stiffening ribs to order, thereby the rigidity of the cylinder head again to increase. It does not matter if they are intake or exhaust ducts, between which the stiffening rib extends.
In einer weiteren Ausgestaltung der Erfindung ragt eine Versteifungsrippe an einem Einlass- oder Auslasskanal in einen Zwischenraum zwischen zwei Versteifungsrippen an einem benachbarten Einlass- oder Auslasskanal hinein. Bei einer derartigen Anordnung der Versteifungsrippen, bei der die Versteifungsrippen zweier benachbarter Gaswechselkanäle wie Zähne zweier Zahnrädern in einander greifen, ist eine hohe Steifigkeit des Zylinderkopfes bei gleichzeitiger guter Verwirbelung des Kühlmittelstromes gegeben. Aufgrund der hohen Steifigkeit des Zylinderkopfes, insbesondere des Zylinderkopfbodens, und der guten Kühlung, bzw. Wärmeabfuhr aus dem Zylinderkopf ist ein derartiger Zylinderkopf besonders geeignet für hochbelastete Brennkraftmaschinen, d.h. höchste Verbrennungsdrücke und -temperaturen werden schadlos über eine lange Lebensdauer ertragen.In a further embodiment of the invention, a stiffening rib protrudes at an inlet or outlet channel into a space between two stiffening ribs at an adjacent inlet or outlet channel. In such an arrangement, the stiffening ribs, in which the stiffening ribs of two adjacent gas exchange channels such as teeth of two gears engage with each other, a high rigidity of the cylinder head is at given at the same time good turbulence of the coolant flow. Due to the high rigidity of the cylinder head, in particular of the cylinder head floor, and the good cooling, or heat dissipation from the cylinder head, such a cylinder head is particularly suitable for highly loaded internal combustion engines, ie highest combustion pressures and temperatures are sustained harmless over a long life.
