Description

Verfahren zum Wiederherstellen von Zündkerzen Es ist allgemein bekannt, daß Zündkerzen für Brennkraftmaschinen nach einer entsprechenden Benutzungsdauer früher oder später verbraucht sind. Dieser Verbrauch entsteht im wesentlichen durch ein Abbrennen der Elektroden.Method of restoring spark plugs It is well known that spark plugs for internal combustion engines after a corresponding period of use are used up sooner or later. This consumption is mainly caused by burning of the electrodes.

Die Folge davon ist ein zu großer Elektrodenabstand und damit verbunden ein Aussetzen der Zündung.The consequence of this is that the electrode spacing is too large and is associated with it ignition failure.

In solchen Fällen ist es zwar möglich, das man durch Nachbiegen der Elektroden den normalen Elektrodenabstand wiederherstellen kann, so daß die Zündkerze vorerst auch wieder arbeitet. Das erfolgt aber nur so kurze Zeit, bis sich der Elektrodenabstand als wieder zu groß erweist, der erwähnte Übelstand des Aussetzens wieder eintritt und sich ein Nachbiegen dann aber nicht mehr vornehmen läßt.In such cases it is possible that you can by bending the Electrodes can restore normal electrode spacing, so that the spark plug works again for the time being. However, this only takes place for a short time until the electrode gap becomes clear proves to be too great again, the aforementioned problem of exposure occurs again and then re-bending can no longer be carried out.

In diesem Falle war dann bisher die Zündkerze infolge ihres Elektrodenverschleißes für die weitere Verwendung nicht mehr zu benutzen und mute verschrottet werden.In this case, the spark plug was previously due to its electrode wear No longer to be used for further use and had to be scrapped.

Durch vorstehende Erfindung ist nun diesbezüglich ein großer Fortschritt erzielt, indem die Lebensdauer einer so verbrauchten Zündkerze ganz bedeutend verlängert wird. Dies wird dadurch erzielt, daß die Mittelelektrode aus dem Kerzenstein entfernt wird, nachdem durch ein an sich bekanntes Lösungsmittel die Befestigungsmasse, die sich zwischen dem Kerzenstein und der Mittelelektrode befindet, erweicht worden ist.The foregoing invention is a great advance in this regard achieved by significantly extending the service life of a spark plug that has been used up in this way will. This is achieved by removing the center electrode from the candle stone is after the fastening compound by a known solvent, which located between the candle stone and the center electrode has been softened is.

Die beschädigte bzw. durch Verschleiß unbrauchbar gewordene Mittelelektrode wird dann ganz nach Umfang des Verschleißes von ihrem Schaftende bzw. von der Schweißstelle entweder abgetrennt und umgekehrt oder, falls der Verschleiß nicht zu groß ist, ausgeglichen.The center electrode that is damaged or unusable due to wear and tear is then entirely depending on the extent of the wear from its shaft end or from the welding point either separated and vice versa or, if the wear is not too great, balanced.

Unter Ausgleich ist zu verstehen, daß die Mittelelektrode um so viel gestrreckt wird, als sie durch den Verschleiß an ihrer ursprünglichen Länge verloren hat.Under compensation is to be understood that the center electrode by so much is stretched as them through wear and tear on their original Has lost length.

Durch die Entfernung der Mittelelektrode aus dem Kerzenstein .ist aber weiter noch einebequeme Zugriffsmöglichkeit zu den Masseelektroden der verbrauchten Zündkerze geschaffen, um auch diese dann durch Strecken oder Umkehren, dem bestehenden Verschleiß entsprechend, bearbeiten zu können.By removing the center electrode from the candle stone .ist but also a convenient way to access the ground electrodes of the used ones Spark plug created to also this then by stretching or reversing, the existing one Wear accordingly to be able to process.

Ist auf diese Weise die Mittelelektrode wiederhergestellt bzw. wiederverwendungsfähig, wird der Kerzenstein wieder mit frischer Befestigungsmasse ausgefüllt und die Mittelelektrode in diesen eingeschraubt.If the center electrode is restored or reusable in this way, the candle stone is again filled with fresh fastening compound and the center electrode screwed into this.
