  • Patent number: 10036355
    Abstract: The present disclosure provides a fuel injector seal assembly comprising a seal member comprising a first section, a second section and an annular recess disposed in the first section, the first section having a first diameter and the second section having a second diameter wherein the first diameter is greater than the second diameter; and a sleeve member comprising a first end received by the first section of the seal member, the sleeve member further including a lengthwise portion configured to press fit around a nozzle housing of a fuel injector to cause heat transfer from the nozzle housing toward a body portion of the fuel injector.
    Type: Grant

  • Patent number: 9410520
    Abstract: This disclosure provides a fuel injector seal assembly comprising a seal component fabricated or formed of a first material and a thermally conductive or heat transfer component fabricated or formed of a second material that is different from the first material. The first material has a greater strength than the second material, and the second material has a greater thermal conductivity than the first material. Thus, the injector seal assembly is able to provide a primary benefit of a combustion seal while also providing an enhanced benefit of transferring heat from one portion of the fuel injector to another portion of the fuel injector.

  • Patent number: 7569143
    Abstract: An apparatus, system, and method are disclosed for enhancing the filtration of small particles from liquid stream. The apparatus includes a fuel filter bank having with at least one fuel filter. The fuel filter bank is mounted on a mounting bracket. The mounting bracket couples to an internal combustion engine with a plurality of vibration dampeners. The engine may have a high pressure common rail fuel system. The vibration dampeners vibrationally isolate the fuel filter bank from the internal combustion engine, reducing the particle slip and degradation of the fuel filter bank.
