Abstract: An engine fuel injector (10) having a fuel inlet tube (12) and a biasing spring (56) loading a solenoid actuated injection valve (50) within the injector (10) is provided with a calibration assembly (58) combining the calibration member (74) or tube with an internally mounted fuel inlet filter (76). The calibration member (74) may include a body (78) with an enlarged end (88) that is interference fitted within the fuel inlet tube (12) and an opposite stepped in end (80) forming a seat (82) which is engaged by the biasing spring (56). The fuel filter (76) has an enlarged annular base (92) fixed within the enlarged end (88) of the calibration member (74) and having an associated filter screen (98) or element through which fuel passing through the calibration member is filtered for passage through the injector (10).

Abstract: A fuel injector for an engine includes a continuous endoskeletal injector tube enclosing an imperforate continuous passage for fuel flow from an inlet end to an outlet end of the tube. A valve seat, injection valve, tubular magnetic pole, biasing spring and adjusting sleeve are mounted within the tube, optionally with other elements, all being exposed to fuel in the passage defined by the tube. A solenoid coil and a magnetic body together with mounting components and seals are mounted on the exterior of the tube where they are protected from exposure to the fuel, which is restricted to passage within the continuous tube. The body, pole and armature form a magnetic flux concentrating path operative to attract the armature to the pole and open the valve when the coil is energized. The solenoid coil may be preassembled with its connector in a body forming a separate coil assembly for subsequent installation on the injector tube.

Abstract: A process for professional authoring of information about structured domains (i.e., not including fiction) by which authors, as an integral part of the authoring process, provide the data needed to (1) enable intelligent user navigation between the work of different authors without the need for predefined links; (2) enable searches for information based on user context; and (3) identify reuse candidates before information is written and, therefore, minimize duplication. Authors develop concept maps to reflect the structure of the domain rather than the structure of the documentation; define the user context to which a concept map applies; resolve topic intersections between concept maps; define query attributes for articles to be developed; and resolve article intersections identified by means of intersecting query attributes. Computer programs support concept map development, the identification and analysis of topic and article intersections, and association of the data for exploitation in a user interface.
