20090250402 | REPLACEABLE FILTER ELEMENTS INCLUDING PLURAL FILTER MEDIA AND RELATED FILTRATION SYSTEMS, TECHNIQUES AND METHODS - 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. | 10-08-2009 |
20100101993 | FILTER CARTRIDGE HAVING A FILTER WITHIN A FILTER, AND AN ENDPLATE SEALING STRUCTURE ON AN OUTER FILTER ELEMENT - A filter within a filter cartridge design is described that includes a sealing structure on an endplate of an outer filter element. Generally, the sealing structure includes an annular flange on the endplate that can directly seal against an interior surface of a housing when the filter cartridge is assembled for use. During filtration, the annular flange prevents a working fluid from bypassing the outer filter element. The sealing flange can seal with the housing in a press fit engagement. | 04-29-2010 |

20120073545 | VARIABLE FLOW FUEL TRANSFER PUMP SYSTEM AND METHOD - A fuel supply system and method of controlling fuel flow through a supply system is provided including a variable flow, i.e. speed, electric fuel transfer pump and a control system adapted to variably control the transfer pump based on fuel demand of the engine. The system provides improved transient response by providing the transfer pump with a feed forward speed/flow command based on engine fueling demand determined based on engine operating conditions. The transfer pump is controlled based on fuel demand not necessarily achieved yet by the high pressure pump and injectors. Therefore, this system controls the EFTP substantially simultaneously with controlling the high pressure pump and injectors to optimize fuel flow through the entire system ensuring the minimum required fuel flow is passing through the second the fuel filtration system, hence maximizing steady state fuel filtration efficiency, and minimizing surge effects on filtration efficiency. | 03-29-2012 |

During filtration, the annular flange prevents a working fluid from bypassing the outer filter element. The sealing flange can seal with the housing in a press fit engagement. | 04-11-2013 |
20130220900 | FILTER COMMUNICATION AND IDENTIFICATION NETWORK - A filter, and a system, such as an engine, that uses the filter are described. A wireless tag, such as an IEEE 1902.1 wireless tag, that communicates using long wave magnetic waves is mounted on the filter head or on the filter. The wireless tag is used to communicate data such as filter identifier and status to a data acquisition system. Further, the data acquisition system can interface to an engine control module or other controller to allow specific control action or diagnostics/fault reporting. | 08-29-2013 |

20140260239 | MULTI-STAGE TURBOCHARGER SYSTEM WITH INTERCOOLING AND AFTERCOOLING - A turbocharged internal combustion engine system includes at least one high pressure turbocharger system and at least one low pressure turbocharger system. An air-to-air intercooler is connected between the low pressure compressor of the low pressure turbocharger system and the high pressure compressor of the high pressure turbocharger system. An air-to-water aftercooler is connected to the intake system between the high pressure compressors and the intakes of the cylinders of the internal combustion engine. | 09-18-2014 |
