  • Publication number: 20180214802
    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.

  • Patent number: 9464591
    Abstract: A cylinder liner sealing arrangement for an internal combustion engine including a cylinder block having cylinder bores, a cylinder head, a cylinder liner within each cylinder bore and a circumferential cut-out formed in the upper and outer surfaces of the cylinder liner. A circular sealing ring is positioned in the circumferential cut-out with the sealing ring contacting at least the cylinder block and the cylinder liner to form a coolant seal therebetween. The sealing ring includes a seal enhancing configuration formed on at least an outer circumferential surface of the sealing ring with the seal enhancing configuration including at least one of an arcuate portion of a “D” ring seal or a plurality of circumferentially extending ribs.

  • 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: 9127617
    Abstract: An improved cooling fluid passage configuration provides for uniformity of cooling about the entire periphery of a cylinder liner of an internal combustion engine in addition to improved cooling by increasing the flow in an upper water jacket of a split water jacket design. The cooling fluid passage configuration also provides a reduced pressure drop between a cylinder liner cooling fluid inlet and a cylinder head cooling fluid outlet when compared to conventional designs with a single head feed line, permitting use of a smaller cooling fluid pump and leading to increased efficiency of the engine.

  • Patent number: 8997715
    Abstract: This disclosure provides a fuel system for supplying fuel to an internal combustion engine, an internal combustion engine that includes such a fuel system, a connector for connecting a single-walled high pressure common rail to a double-walled fuel line segment, and a fluid containment system. Each embodiment includes drain plumbing having a leakage drain connector that can be used to provide an interface between a single-walled high pressure common rail and a double-walled high pressure fuel line segment, and also provide part of a low pressure passage fluidly connected with a low pressure passage of the double-walled high pressure fuel line segment. The drain plumbing also can provide an interface with a low pressure fuel drain line fluidly coupled to a leakage detector.

  • Patent number: 8844503
    Abstract: 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.

  • Patent number: 8752527
    Abstract: This disclosure provides a fuel line assembly for use with an internal combustion engine, an internal combustion engine including such as fuel line assembly, and a method for providing leak containment and detection in a fuel system, each of which include a double-walled fuel line including a high pressure fuel line component. The double-walled fuel line includes a high pressure fuel line, a jacket surrounding the high pressure fuel line, and a low pressure passage between the high pressure fuel line and the jacket. A fuel line nut includes a main body that houses a portion of the high pressure fuel line, and a first end portion supporting an enlarged end portion of the high pressure fuel line protruding from the first end portion. A second end portion of the fuel line nut sealingly connects to the jacket to extend the low pressure passage into an area between the main body and the housed high pressure fuel line.
