Description
Die Erfindung betrifft einen Zylinderblock einer flüssigkeitsgekühlten Brennkraftmaschine mit einem im wesentlichen aus Magnesium bestehenden Gehäuse und mehreren in Reihe angeordneten Zylindern.The The invention relates to a cylinder block of a liquid-cooled internal combustion engine with a housing consisting essentially of magnesium and several cylinders arranged in series.
Zum
technischen Umfeld der Erfindung wird beispielsweise auf die
Zylinderblöcke bzw. Kurbelgehäuse aus Magnesium sind an luftgekühlten Brennkraftmaschinen bekannt. Dabei zeichnet sich ein Gehäuse aus Magnesium durch ein äußerst geringes Gewicht aus. Jedoch ergeben sich bei der Verwendung von Magnesium-Zylinderblöcken an flüssigkeitsgekühlten bzw. wassergekühlten Brennkraftmaschinen erhebliche Korrosionsprobleme im Wassermantelbereich. Darüber hinaus sind zusätzliche Maßnahmen erforderlich, um die Zylinderlaufbahnen verschleißfest zu machen.Cylinder blocks or crankcase Made of magnesium are air-cooled Internal combustion engines known. It is characterized by a housing Magnesium by an extremely low Weight off. However, arise when using magnesium cylinder blocks liquid-cooled or water-cooled internal combustion engines considerable corrosion problems in the water jacket area. Furthermore are additional activities required to wear the cylinder liners wear-resistant do.
Maßnahmen zur Lösung der geschilderten Problematik aufzuzeigen, ist Aufgabe der vorliegenden Erfindung.activities to the solution To show the described problem is the task of the present Invention.
Zur Lösung dieser Aufgabe ist vorgesehen, daß die Zylinder Bestandteil eines bereichsweise doppelwandigen, mit dem Gehäuse verbundenen Zylindereinsatzes aus korrosionsbeständigem Material sind, in dem die Kühlflüssigkeit geführt ist, ohne mit dem Magnesium-Gehäuse in Kontakt zu kommen. Vorteilhafte Aus- und Weiterbildungen sind Inhalt der Unteransprüche.to solution This object is provided that the cylinder component a partially double-walled, with the housing associated cylinder insert made of corrosion resistant Material are in which the coolant guided is without the magnesium case to get in touch. Advantageous training and further education are Content of the subclaims.
Erfindungsgemäß bilden zusammenhängende Zylinder mit integriertem Wassermantel einen Teil des Zylinderblockes und sind hierzu mit dem Magnesium-Gehäuse verbunden. Dabei werden die zusammenhängenden Zylinder als Zylindereinsatz bezeichnet und können insbesondere in das Magnesium-Gehäuse eingegossen sein. Der Zylindereinsatz besteht aus korrosionsbeständigem Material, vorzugsweise einer Aluminium-Legierung, und kann in Druckguß vorgeformt sein, wobei die Wände des Zylindereinsatzes relativ dünn ausgebildet werden können. Dabei können an den Zylinderlaufbahnen die bei Aluminium-Zylinderblöcken bewährten Verschleißschutzmaßnahmen ergriffen werden. Bei Verwendung einer geeigneten Aluminium-Legierung ist beispielsweise eine Nicasil-Beschichtung oder der Einsatz von Locasil-Buchsen möglich.Form according to the invention related Cylinder with integrated water jacket a part of the cylinder block and are for this purpose connected to the magnesium housing. It will be the coherent ones Cylinder referred to as a cylinder insert and can be cast in particular in the magnesium housing be. The cylinder insert is made of corrosion-resistant material, preferably an aluminum alloy, and may be preformed in die cast be the walls the cylinder insert is relatively thin can be trained. It can on the cylinder liners the proven wear protection measures for aluminum cylinder blocks be taken. When using a suitable aluminum alloy is for example a Nicasil coating or the use of Locasil sockets possible.
Erfindungsgemäß ist der Kühlflüssigkeits-Mantel bzw. Wasser-Mantel in den Zylindereinsatz integriert, so daß zwischen dem Magnesium-Gehäuse sowie der Kühlflüssigkeit kein Kontakt stattfindet. Eine Korrosion des Magnesium-Gehäuses wird damit erfolgreich verhindert. Im Zulauf- und Ablaufbereich zum bzw. vom Kühlflüssigkeits-Mantel sind selbstverständlich geeignete Abdichtmaßnahmen zu ergreifen, um zu verhindern, daß in diesem Bereich die Kühlflüssigkeit mit den Magnesium-Oberflächen des Gehäuses in Kontakt kommt. Beispielsweise können in diesem Bereich Metalldichtungen insbesondere mit Gummierung vorgesehen sein.According to the invention Coolant jacket or water jacket integrated into the cylinder insert, so that between the magnesium housing and the coolant no contact takes place. A corrosion of the magnesium casing will thus successfully prevented. In the inlet and outlet area to or from the coolant jacket are Of course suitable sealing measures to take to prevent the coolant in this area with the magnesium surfaces of the housing comes into contact. For example, in this area metal seals in particular be provided with rubber coating.
In einer bevorzugten Ausführungsform weist der Zylindereinsatz insbesondere im oberen Bereich, der einem Zylinderkopf der Brennkraftmaschine zugewandt ist, eine Hüllwand auf, die die Einzelzylinder umgibt und die an deren Zylinderwänden angeformt ist. Die Zylinderwände sowie die Hüllwand begrenzen somit einen die Einzelzylinder quasi umgebenden Kühlflüssigkeitsraum. Ist dieser Kühlflüssigkeitsraum zum Zylinderkopf hin, d. h. nach oben hin vollständig offen, so kann der Zylindereinsatz einfach in Druckguß gefertigt werden. Dabei kann der Kühlflüssigkeitsraum nur über den zum Zylinderkopf hin offenen Abschnitt mit dem Kühlflüssigkeitskreislauf der Brennkraftmaschine, der im Zylinderkopf geführt ist, verbunden sein. Diese Ausbildung bietet sich insbesondere für die sog. Phasenwechselkühlung, bei der die Kühlflüssigkeit in der Brennkraftmaschine einen Phasenübergang vom flüssigen in den dampfförmigen Zustand durchführt, an. Es kann jedoch auch die Kühlflüssigkeit von außen her bevorzugt in den unteren Bereich des Kühlflüssigkeitsraumes zugeführt werden. Hierzu weist die Hüllwand bevorzugt einen Übertrittsstutzen auf, der das Magnesium-Gehäuse im wesentlichen durchdringt.In a preferred embodiment the cylinder insert in particular in the upper area, the one Cylinder head of the internal combustion engine facing, a shell wall, which surrounds the individual cylinder and which is integrally formed on the cylinder walls. The cylinder walls as well as the shell wall thus limit a cooling liquid space quasi surrounding the individual cylinder. Is this coolant space to Cylinder head out, d. H. fully open at the top, so can the cylinder insert simply manufactured in die casting become. In this case, the cooling liquid space only over the section with the coolant circuit open towards the cylinder head the internal combustion engine, which is guided in the cylinder head, be connected. These Training is particularly suitable for the so-called. Phase change cooling, at the coolant in the internal combustion engine, a phase transition from the liquid in the vaporous Condition, at. However, it can also be the coolant from the outside preferably be supplied in the lower region of the cooling liquid space. For this purpose, the envelope wall prefers a transfer socket on top of the magnesium case in the essentially permeates.
