摘要： A fuel rail damper includes a hollow member having a first end and a second end, opposing first and second sides, a first face and a second face interconnecting and spacing apart the first and second sides, and a width. Each of the first and second ends are sealed in an air tight manner to thereby define a chamber in conjunction with the first and second sides and the first and second faces and wherein the widths of the ends do not substantially exceed the hollow member width.

摘要： A liquid cooled fuel rail assembly includes an elongate tubular fuel conduit having a longitudinal central axis and a first diameter. The fuel conduit is configured for carrying fuel and defines at least one port, each port being configured to receive an intake end of a corresponding fuel injector. A first end plug is associated with a first end of the fuel conduit and defines a first bore and a second bore therethrough. The first end plug seals the first end of the fuel conduit. A second end plug is associated with a second end of the fuel conduit and defines a first bore and a second bore therethrough. The second end plug seals the second end of the fuel conduit. A fuel inlet is in fluid communication with the second bore of the first end plug. A fuel outlet is in fluid communication with the second bore of the second end plug. An elongate tubular coolant conduit has a second outside diameter that is less than the first outside diameter of the fuel conduit. A first segment of the coolant conduit is disposed entirely within and surrounded by the fuel conduit. The coolant conduit extends through the first bore of the first end plug and through the first bore of the second end plug. The coolant conduit is configured for carrying coolant.

摘要： A fuel accumulator is provided to assist restarting a direct injection engine fuel system. The fuel accumulator includes a central guide post with a fuel passage. A cup shaped plunger with a closed end is slideably disposed on the central guide post. A seal means is disposed between the plunger and the central guide post to define a substantially sealed fuel chamber. A biasing means is provided to urge the plunger onto the central guide post. A fuel admission valve selectively prevents and permits fuel from entering and exiting the fuel accumulator. When a fuel system stop is commanded, pressurized fuel is admitted into the fuel chamber, thereby compressing the biasing means which maintains a restart pressure. When a fuel system start is commanded, pressurized fuel is expelled from the fuel accumulator.
