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.

Abstract translation: 本公开提供了一种燃料喷射器密封组件，其包括由第一材料制成或形成的密封部件，以及由与第一材料不同的第二材料制造或形成的导热或传热部件。 第一材料具有比第二材料更大的强度，并且第二材料具有比第一材料更大的热导率。 因此，喷射器密封组件能够提供燃烧密封的主要益处，同时还提供将热量从燃料喷射器的一部分传递到燃料喷射器的另一部分的增强益处。

Abstract: A fuel filtration system and methods controlling, and operating a fuel filtration system. A first fuel filter head is fluidly coupled to one or more first fuel filters, a second fuel filter head is fluidly coupled to one or more second fuel filters and a selector valve is coupled to the first fuel filter head and the second fuel filter head. The selector valve includes a primary valve inlet port, a primary valve outlet port, and a movable valve body movable from a first position to a second position. The first position fluidly couples the first fuel filter head to the primary valve outlet port and fluidly decouples the second fuel filter head from the primary valve outlet port. The second position fluidly couples the second fuel filter head to the primary valve outlet port and fluidly decouples the first fuel filter head from the primary valve outlet port.
