摘要： A self-damping fuel rail for a fuel-injected internal combustion engine includes an elongated tube defining a wall and having a longitudinal axis. The wall defines a fuel passageway and has a first wall portion movable between a first position bowed inwardly toward the longitudinal axis when the self damping fuel rail is in a non-operative state, and a second position moved outwardly away from the longitudinal axis when the self-damping fuel rail is in an operative state. The self-damping fuel rail also includes at least one fuel outlet configured to facilitate communication between the fuel passageway and a fuel injector.

摘要： A reusable torque limiting device producing tactile feedback for a desired preset bolt tensile load comprises a body, provided with an internal bore threaded therethrough so as to be received over a threaded bolt or similar fastening element. One face of the body is provided with a recessed area therein and an angled counter-bore adjacent and concentric with the center thereof. One or more angular, beveled or concave members are disposed within a recess in the body with the concave portion suitably oriented relative to the recess. The work piece engaging face of the body is, or may be provided with, a roughened surface for example radial slots, notches, teeth or grooves so as to gall or abraid the confronting face of the work piece as the device achieves the predetermined bolt tensile load that is desired by allowing the torque rate increase to be easily sensed at which time the operator should stop turning the nut. (This device makes use of the operator tactile senses to achieve accurate tensile load in the bolts.) Additionally, an indication that the annular beveled members are located correctly within the recess in the threaded body of the device is provided by the slots or grooves.

摘要： A fuel injection system and method includes a cylinder head having an injector port. A fuel injector has a first end and a second end, the second end being received in the injector port. A fuel rail includes a socket for receiving the first end of the fuel injector. A spring assembly is coupled between the fuel rail and the injector to bias the injector toward the cylinder head. The spring assembly includes a housing, a spring in the housing, and a viscous material at least partially surrounding the spring in the housing. The spring assembly utilizes a squeeze film effect to resist movement of the injector in a direction toward the fuel rail. Preferably, the spring is comprised of a plurality of alternatingly-oriented disc springs, and the viscous material is a grease.
