摘要:
An apparatus, system, and method are disclosed for multistage water separation. A first separation layer separates water droplets from a fuel flow by repelling the first water droplets. A coalescing layer may coalesce fine water droplets in the fuel flow. In one embodiment, a centrifugal separator directs the fuel flow tangentially to a filter wall and the centrifugal force of the fuel flow directed tangentially along the filter wall biases water droplets from the fuel flow. A second separation layer separates second water droplets from the fuel flow.

One embodiment is a filter element including an outer filter media and an inner filter media. The outer filter media is operable to remove particulates present in a flow of fluid and/or coalesce water contained in the flow of fluid. The inner filter media is operable to remove particulates from the flow of fluid, separate water form the flow of fluid, and remove particulates from the flow of fluid. Other embodiments include unique apparatus, devices, systems, and methods relating to fuel filters and filtration. Further embodiments, forms, objects, features, advantages, aspects, and benefits of the present application shall become apparent from the detailed description and figures included herewith.
摘要:
Various “no filter, no run” fuel filtration designs are described that include a variable restriction orifice (VRO) designed to vary the amount of fluid, for example fuel, that reaches a fluid outlet. The VRO has a fully open position at which a maximum non-zero fluid flow is permitted, and a fully closed position at which a limited amount of fluid can flow to the outlet. In the case of diesel fuel, the amount of fuel flow permitted at the fully closed position provides lubrication of downstream fuel system components, for example the fuel pump, but is insufficient to permit engine operation.
摘要:
A simple pass-fail tool that can be used to test the particulate contamination level in a fluid. The tool relies upon a comparison between a measured indicator of the contamination level in the fluid with another indicator of a contamination level of the fluid. Based on the comparison, conclusions about the contamination level of the fluid, and decisions about the fluid, for example that the fluid is acceptable for a particular use, can be made. The fluid can be fuel, lubrication, power transfer, heat exchange or other fluids used in a fluid system, for example fuel injection systems of diesel engines or hydraulic systems, where contamination of the fluid is of concern and use of an excessively contaminated fluid is to be avoided.
摘要:
A filter, system and method is provided for filtering nanoparticles in a hot gas, namely particles about 200° C. and further particularly >about 450° C. including diesel exhaust. The filter includes filter media material composed of fibrous filter media having a plurality of fibers and granular filter media having a plurality of granules extending from the surfaces of the fibers. The filter is characterized by a permeability >about 3×10−12 m2 and an inertial resistance coefficient
