    摘要： A fluid filter increases the useful life of the filtered fluid by removing contaminants therefrom, and may optionally provide for in-line delivery of additives to the filtered fluid. The filter may be an oil filter, a fuel filter, or other fluid filter. The fluid filter includes a casing which defines a hollow space therein, a mechanically active filter element within that space, and a chemically active filter element also retained within the hollow space proximate the mechanically active filter element. The chemically active filter element includes a nonwoven web made up of a plurality of fibers. Each fiber has a longitudinally extending internal cavity formed therein, and a corresponding longitudinally extending slot opening from that internal cavity to the outer surface of the fiber. Preferably each fiber as multiple lobes extending radially outwardly from a central stem, and each lobe cooperates with an adjacent lobe to define a longitudinally extending internal cavity and a corresponding slot therebetween. In order to remove contaminants or to supply additives to lubricating oil, the internal cavities, of each of the chemically active filter fibers, are supplied with a chemical reagent therein.

    摘要： An improved oil conditioning filter, for use with an internal combustion engine, includes a mechanically active filter element and a chemically active filter element having a reactive basic conditioner therein. The reactive basic conditioner is provided to counteract acidic combustion products in lubricating oil in an internal combustion engine. In a preferred embodiment of the invention, the chemically active conditioning agent is provided in a plurality of pellets disposed within the oil filter housing. The pellets may be bonded together to form an integral porous filter element having spaces defined between the pellets thereof. The pellets are made of a mixture including a polymeric binder and the chemically active conditioning agent, in a defined weight ratio and in a narrow range of particle sizes. The chemically active filter element reacts with acids present in the oil to form a product which may be filtered out of the oil. The pellets are made either by a hot extrusion process or by a solvent process.

    摘要： Disclosed is a fuel filter for removing sulfur containing compounds from an internal combustion fuel stream. In one embodiment, the fuel filter comprises at least one column comprising an adsorbent. In one exemplary embodiment the adsorbent is capable of removing sulfur containing compounds, especially sulfur containing aromatic compounds, from fuels used in internal combustion engines, especially diesel fuels. Also disclosed is an apparatus for extending the life cycle of a post combustion emission control device. In one exemplary embodiment, the apparatus comprises a fuel filter for removing sulfur containing compounds from an internal combustion fuel stream and an emission control device. Finally, a method for removing sulfur containing compounds from an internal combustion fuel stream is disclosed. In one exemplary embodiment, the method comprises passing a fuel through a fuel filter capable of removing sulfur containing compounds, storing the removed sulfur containing compounds, releasing a portion of the stored sulfur containing compounds, and sending the portion through the engine and into an emission control device.
