  • METHOD AND APPARATUS FOR REMOVAL OF PARTICLES FROM LUBRICATING OIL
    Publication number: 20130026039
    Abstract: A method for removing soot, sludge, varnish and other insoluble particulates from engine oil, the method including the steps of: disposing an oil containing the particulates between a pair of electrodes, wherein one of the electrodes is a collecting electrode; wrapping a surface of the collecting electrode with a media, wherein the media is configured to collect a portion of the particulates drawn towards the collecting electrode; applying a direct current to the electrodes for a period of time to generate an electric field, wherein the electric field causes a portion of the particulates to agglomerate in the media; and removing the media and the portion of particulates agglomerated in the media to reduce the amount of soot particles in the oil.
