  • 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.
    Type: Grant

  • 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.
