摘要:
A fuel filtration apparatus for use in an internal combustion engine comprises an interrupter valve in a flow path from an inlet port of a filter head to a compliant filter. The interrupter valve has an open state and a closed state. In the open state a protruding member of the filter depresses a bottom end of the valve and opens the flow path when the compliant filter is connected to the filter head. The interrupter valve also has a closed state wherein the flow path is closed in the absence of the protruding member of the filter (as with a non-compliant filter).

A filter includes a filter element formed of filter media, and a plastic framework molded and bonded to and structurally supporting the filter media. One embodiment desirably provides a two-component assembly consisting solely of two components, namely the filter media and the plastic framework molded thereon. In a further embodiment, the plastic framework includes a resilient seal integrally molded therewith and of the same plastic material thereof, eliminating a separate component for the seal. In a further embodiment, a filter combination includes a primary filter element and a secondary filter element. In a further embodiment, a resilient integrally. molded seal is provided.

Systems and methods used to monitor a fluid where it is important to know the size, concentration and nature of particulates in the fluid. For example, the systems and method can be used to diagnose contamination issues in fluids such as fuel, lubrication, power transfer, heat exchange or other fluids in fluid systems, for example diesel engines or hydraulic systems, where contaminant particles in the fluids are of concern.
摘要:
A filter includes first and second sheets of filter media, the second sheet being pleated and forming with the first sheet a plurality of axially extending flow channels having lateral cross-sectional shapes with two adjacent included angles each greater than 45° and less than 75°. Forming apparatus and methods are provided.
摘要:
A selective catalytic reduction system for engine exhaust injects a source of ammonia, preferably an aqueous urea solution, or other ammonia solution, to preferably evaporate, decompose and hydrolyze to produce ammonia to react with and reduce NOx in the exhaust. A turbulence generator between the injector and a downstream catalyst enhances ammonia mixing upstream of the catalyst. A perforated reflector between the injector and the catalyst passes the exhaust through the perforations and reflects exhaust back toward the injector, to generate the turbulence to achieve enhanced ammonia mixing. A low pressure generator creates a low pressure evaporative diffusion enhancement zone at the injector accelerating evaporation rate and accelerating ammonia diffusion and mixing with the exhaust.
摘要:
A lubricant filtering and monitoring system and method is provided for a lubricant circulation system circulating lubricant through a filter to a lubricated component. A combination of sensors senses a condition of the lubricant before and after passage through the filter and before and after passage through the component and provides an output indicative of a condition in the circulation system. A sensor senses a condition of lubricant flowing through the filter, and another sensor senses a condition of lubricant flowing through a reference section for comparison against and normalizing of the output of the first sensor. A method of actively monitoring the component is provided by comparing influent to the component with effluent from the component to ascertain how lubricant is being modified by the component, by sensing a condition of lubricant passing through the filter. An effective method is provided for determining when to change or clean the filter. A diagnostic method is provided for assisting in such determination and diagnosing lubricant condition, filter condition and component condition.
摘要:
A process, system, and component configuration are described that discourages customer acceptance/use of will-fit, reconditioned, and counterfeit product components, by determining whether or not a serviceable product component is genuine. If a component is determined to not be genuine, then appropriate action may be taken to warn operators and document such findings. For example, one or more markers are disposed or otherwise put on the subject serviceable product component and serves as a targeted feature, and/or a particular characteristic of the filter itself is identified as the targeted feature. A sensor is used to detect the targeted feature and obtain information unique to the serviceable product component. The targeted feature(s) identifies the particular serviceable component as genuine and forms the basis for determining whether a genuine component has been installed. In some circumstances, a fluid filter product is the component that is the subject detection.

Disclosed are coalescers, systems, and methods for coalescing a mixture of two phases, namely a continuous phase and a dispersed phase. The disclosed coalescers, systems, and methods include or utilize one or more layers of media material having a distinct mean pore size and wettability. The disclosed coalescers, systems, and methods are effective for removing the dispersed phase from the mixture.
