Description

Einrichtung zur Verhütung der Anfressung der die Kühlwasserräume von Brennkraftmaschinen begrenzenden Wandungen Es ist bekannt, zur Verhütung der Anfressung - von Brennkraftmaschinenteilen durch Kühlwasser Zink in Form von Platten oder Blöcken in den von Kühlwasser durchflossenen Räumen anzuordnen und dieses mit den gefährdeten Eisenteilen elektrisch leitend zu verbinden. Das Eisen des Maschinengestells bzw. der Zylinderbüchsen und das Zink wirken dann als Elektroden eines elektrochemischen Elementes, in welchem das Kühlwasser den Elektrolyten darstellt. Das Zink als die Elektrode J mit dem höheren Potential stellt dabei die Kathode dar und wird im Laufe der Zeit vollkommen zersetzt, während das Eisen in diesem Fall nicht angegriffen wird. Ein solcher Zinkschutz hat sich im allgemeinen gut bewährt. Die bisherigen Ausführungen haben jedoch den Nachteil, daß durch die Anordnung der Zinkelektroden der Kühlwasserraum stark beengt wird und an den betreffenden Stellen Wirbelbildungen im Kühlwasserstro-m auftreten, wodurch die Kühlwirkung erheblich herabgesetzt wird. Außerdem war der Zinkschutz in den meisten Fällen nicht ausreichend, da man größere Zinkmengen, die wegen der örtlich begrenzten Wirkung 'des Zinkschutzes erforderlich sind, in den Kühlwasserräumen nicht unterbringen konnte.Device to prevent the seizure of the cooling water spaces Internal combustion engine delimiting walls It is known to prevent seizure - of internal combustion engine parts through cooling water zinc in the form of plates or blocks to be arranged in the rooms through which the cooling water flows and this with the endangered To connect iron parts electrically conductive. The iron of the machine frame or the cylinder liners and the zinc then act as electrodes of an electrochemical Element in which the cooling water represents the electrolyte. The zinc than that Electrode J with the higher potential represents the cathode and becomes in the course of completely decomposed over time, while the iron in this case is not attacked will. Such zinc protection has generally proven to be effective. The previous However, designs have the disadvantage that the arrangement of the zinc electrodes the cooling water space is very narrow and vortices are formed at the relevant points occur in the cooling water flow, which significantly reduces the cooling effect. In addition, the zinc protection was in most cases inadequate, as one larger Amounts of zinc required because of the localized effect of the zinc protection could not be accommodated in the cooling water rooms.

Um diesen Nachteil zu vermeiden, sind erfindungsgemäß in die Kühlraumwandungen großflächige Zinkplatten derart eingelassen, daß sie den Kühlraum nicht oder nur unwesentlich verengen und keinen Anlaß zur Wirbelbildung- im Kühlwasserstrom geben. Die Zinkplatten stehen mit den Kühlraumwandungen stromleitend in Verbindung. Da der Zinkschutz örtlich begrenzt ist, müssen neben den durch das Maschinengestell gebildeten Kühlraumwänden auch die Zylinderbüchsen besonders geschützt werden, was durch einen umgelegten Mantel aus Zinkblech geschieht, der einerseits eine große Flächenausdehnung hat und andererseits den Kühlwasserdurchfluß ebenfalls nicht behindert.In order to avoid this disadvantage, according to the invention, are in the cold room walls large zinc plates let in so that they do not or only the cooling space Narrow insignificantly and give no cause for vortex formation in the cooling water flow. The zinc plates are electrically connected to the walls of the cold room. There the zinc protection is locally limited, must in addition to that by the machine frame formed cold room walls also the cylinder liners are specially protected what happens through a folded sheet of zinc sheet, on the one hand a large Area has and on the other hand the Cooling water flow also not disabled.

In der Zeichnung ist ein Brennkraftmaschinengestell mit der Einrichtung nach der Erfindung dargestellt, und zwar zeigen-. In the drawing, an internal combustion engine frame with the device according to the invention is shown, namely show .

Abb. i einen Axialschnitt durch einen Teil eines Brennkraftmaschinengestells nach der Linie 1-1 in Abb. z und Abb.2 einen Ouerschnitt durch das Maschinengestell nach der Linie II-II in Abb. i. Die Wandungen i des Brennkraftmaschinengestells umschließen zusammen mit den Zylinderbüchsen 2 den Kühlwasserraum 3. In den Wänden i sind die zinkplatten q. derart eingelassen, daß sie den Kühlwasserraum 3 nicht beengen und auch keinen Anläß zur Wirbelbildung im Kühlwasserstroni geben. Befestigt- sind die Zinkplatten .4 je zweier benachbarter Zylinder gemeinsam mittels Schrauben mit versenkten Köpfen und Muttern oder sonst irgendeiner anderen leicht lösbaren Befestigungsart. Bei den Zylinderbüchsen 2 ist die Zinkelektrode in Form eines Blechmantels 6 um die Büchsen gelegt und mit ihnen stromleitend verbunden. Nach Herausnahme der Zylinderbüchsen 2 lassen sich die zersetzten Zinkplatten' und -bleche sehr bequem durch neue auswechseln.Fig. I an axial section through part of an internal combustion engine frame according to the line 1-1 in Fig. z and Fig. 2 a cross-section through the machine frame according to the line II-II in Fig. i. The walls i of the internal combustion engine frame together with the cylinder liners 2 enclose the cooling water space 3. In the walls i are the zinc plates q. let in in such a way that they do not enter the cooling water space 3 narrow and do not give any cause for vortex formation in the cooling water stream. Attached- are the zinc plates .4 of two adjacent cylinders together by means of screws with countersunk heads and nuts or any other easily detachable Type of attachment. In the case of the cylinder liners 2, the zinc electrode is in the form of a sheet metal jacket 6 placed around the sockets and electrically connected to them. After removing the Cylinder liners 2 can be the decomposed zinc plates' and sheets very conveniently replace with new ones.
