  • Patent number: 8388838
    Abstract: A filter, comprising: a housing defining an inlet fluid opening and an outlet fluid opening, the inlet fluid opening and the outlet fluid opening defining a fluid path through the filter; a filter element disposed inside the filter housing, the filter element being disposed in the flow path such that fluid flowing through the flow path must pass through the filter element; and a dispersement device disposed within the housing, the dispersement device comprising a housing having at least one chamber for an additive disposed within the at least one chamber, the dispersement device further comprises a metering opening that is sealed with an oil soluble material the metering opening being in fluid communication with the at least one chamber when the oil soluble material is removed from the metering opening.

  • Publication number: 20100101959
    Abstract: A method for removing soot, sludge and other insoluble particulates from an engine oil is provided, the method comprising: disposing an oil containing the particulates between a pair of electrodes, wherein one of the electrodes is a positive electrode; applying a coating to the surface of the positive electrode, wherein the coating is configured to collect a portion of the particulates on the positive electrode; applying a current to the electrodes for a period of time, wherein portions of the particulates agglomerate on the positive electrode and other portions of the particulates not collected on the positive electrode are preagglomerated resulting in a larger average particle size; and applying a filtering process to remove the particulates not collected on the positive electrode. Also, disclosed herein is a filter for removing soot, sludge and other insoluble particulates from an engine oil.
