Description

  

      Reinigungsmittel    für Zündkerzen.    Zündkerzen setzen bekanntlich während  des Gebrauches einen Belag auf dem untern  Teil des Isolators,     ,dem    sogenannten     Isolator-          fuss,    und den Elektroden an. Dieser bei  Temperaturen     zwischen    etwa 700 und  1200  C sich bildende Belag     besteht    neben       ,Ölkohle    vor allem auch aus Metalloxyden.

    Überschreitet die von ihm     bedeckte    Fläche  auf dem Isolator eine bestimmte Grösse, so       entstehen    dadurch Störungen im     Betrieb    der  Zündkerze, indem kein     regelmässiger    Fun  kenüberschlag zwischen     Mittel-    und Masse  elektrode mehr stattfindet.

   Der Strom sucht  sich dann den bequemeren Weg von der  Mittelelektrode über den Belag zum Kerzen  gehäuse und damit zu der mit -dem     Kerzen-          gehguse    leitend verbundenen     Masseelektrode.     Solche verschmutzten Zündkerzen wurden  bisher als unbrauchbar weggeworfen     und          muss.ten        stets    durch neue ersetzt werden.  



  Es .sind zwar zum Entfernen der an den  innern Teilen von     Verbrennungsmotoren,     ausserhalb der Zündkerze, im Lauf ihres Be  triebes sich bildenden Rückstände, welche         infolge    dort     herrschenden    niederen     Ent-          stehungstemperaturen    (etwa 150 bis     850     C)  im     wesentlichen        nur    aus     Ölkohle    allein be  stehen,     bereits        gewisse        Reini,g-ungsmittel     im Gebrauch.

   Sie bestehen     entweder    in       fester    Form,     beispielsweise    aus Zinkpulver,  Paraffin, Stearin und Naphthalin, oder in  flüssiger Form aus Benzol, Holzgeist,  Azeton,     Kohlenstofftetrachlorid        bezw.    an  dern diesen     Lösungsmitteln    gleichwertigen  Stoffen. Mit diesen bekannten Mitteln ge  lingt es jedoch nicht, den, wie oben er  wähnt, zusätzlich zur Ölkohle noch aus       Metaflogyden    gebildeten Belag auf den       Zündkerzenisolatoren    zu entfernen.  



  Die Erfindung bezieht sich nun auf ein  Reinigungsmittel, durch dessen Anwendung       gebrauchte    und     verschmutzte    Zündkerzen  von dem     erwähnten        leistenden    Belag befreit  und darnach wieder im Motor verwendet  werden können.  



       Dieses    Reinigungsmittel besteht aus einer       Mischung,    welche folgende - Stoffe enthält:  Kampfer, einen chlorierten     aliphatischen         Kohlenwasserstoff, ein     aliphatisches    .     Keton,          einen        Ester        einer        niederen     wachsartigen Stoff, wie z. B.     Pär\affiri    oder  Wachs, sowie noch ein flüssiges, höher als       100     C -siedendes, aus     Kohlenwassersfoffen     bestehendes Harz- und Fettlösungsmittel,  wie z. B.

   Terpentinöl oder     Schwerbenzin.     



  Zweckmässig kann die Mischung aus  Kampfer,     Trichloräthylen,    Azeton,     Amyl-          azetat,    Paraffin und     Terpentinöl    aufgebaut  sein, wobei an Stelle von Paraffin auch  Wachs und an Stelle von Terpentinöl  Schwerbenzin verwendet     werden    kann.  



  Bei Anwendung dieses neuen Reinigungs  mittels wird der Belag zunächst aufgeweicht  und kann dann leicht abgelöst werden.  



  Für die mengenmässige Verteilung der  einzelnen Bestandteile haben sich folgende  Verhältnisse bewährt:  5- 15 g Kampfer  200-300 g     Trichloräthylen    (als chlorierter       aliphatiseher    Kohlenwasserstoff)  200-300 g     Azeton    (als     aliphatisches        Keton)     20- 60 g     Amylazetat    (als     Ester    niederer  Fettsäuren)  20- 80 g Paraffin  300-500 g Terpentinöl    Sehr gute Wirkungen, selbst bei stark  verschmutzten Kerzen, können mit einem    Reinigungsmittel folgender Zusammensetzung  erreicht werden:

      50 g Paraffin  250 g     Trichloräthylen     10 g Kampfer  250g Azeton  400g Terpentinöl  40 g     Amylazetat  



      Cleaners for spark plugs. As is well known, spark plugs apply a coating to the lower part of the insulator, the so-called insulator base, and the electrodes during use. This deposit, which forms at temperatures between around 700 and 1200 C, consists not only of oil carbon but also, above all, of metal oxides.

    If the area covered by it on the insulator exceeds a certain size, this will cause malfunctions in the operation of the spark plug, as there will no longer be a regular sparkover between the center and ground electrodes.

   The current then seeks the more convenient route from the center electrode over the covering to the candle housing and thus to the earth electrode that is conductively connected to the candle housing. Such contaminated spark plugs were previously thrown away as unusable and always had to be replaced with new ones.



  It is used to remove the residues that form on the inner parts of internal combustion engines, outside the spark plug, in the course of their operation, which, due to the low temperatures prevailing there (around 150 to 850 C), consist essentially only of oil carbon alone , certain cleaning agents are already in use.

   They consist either in solid form, for example from zinc powder, paraffin, stearin and naphthalene, or in liquid form from benzene, wood spirit, acetone, carbon tetrachloride and / or. on substances equivalent to these solvents. With these known means, however, it does not succeed in removing the coating on the spark plug insulators formed from Metaflogyden in addition to the oil carbon, as mentioned above.



  The invention now relates to a cleaning agent, through the use of which used and soiled spark plugs are freed from the above-mentioned coating and can then be used again in the engine.



       This cleaning agent consists of a mixture which contains the following substances: Camphor, a chlorinated aliphatic hydrocarbon, an aliphatic. Ketone, an ester of a lower waxy substance, such as B. Pär \ affiri or wax, as well as a liquid, higher than 100 C -boiling, consisting of hydrocarbons resin and fat solvent such. B.

   Turpentine oil or heavy gasoline.



  The mixture of camphor, trichlorethylene, acetone, amyl acetate, paraffin and turpentine oil can expediently be made up, it being possible to use wax instead of paraffin and heavy gasoline instead of turpentine oil.



  When using this new cleaning agent, the covering is first softened and can then be easily removed.



  The following proportions have proven to be effective for the quantitative distribution of the individual components: 5-15 g camphor 200-300 g trichlorethylene (as a chlorinated aliphatic hydrocarbon) 200-300 g acetone (as aliphatic ketone) 20- 60 g amyl acetate (as an ester of lower fatty acids) 20-80 g paraffin 300-500 g turpentine oil Very good effects, even with heavily soiled candles, can be achieved with a cleaning agent of the following composition:

      50 g paraffin 250 g trichlorethylene 10 g camphor 250 g acetone 400 g turpentine oil 40 g amyl acetate
