  • Patent number: 7252282
    Abstract: In a vehicle solenoid valve, the spool that holds the actuation coil is formed with a hexagonal or octagonal inner chamber in which a cylindrical armature can slide. Owing to the different cross-sectional shapes between the spool and armature, a longitudinal fluid vent passageway is established along each edge of the chamber between the non-cylindrical walls of the chamber and the cylindrical armature so that movement of hydraulic fluid relative to the armature is promoted when the armature moves. The face of the spool that is oriented toward the valve end can be formed with radial vent grooves to further facilitate fluid venting when the armature moves.

  • Patent number: 7254478
    Abstract: A method of estimating the quantity of secondary reaction airflow supplied to the exhaust manifold of an internal combustion engine by an air injection reaction (AIR) system models airflows in an AIR pump, an AIR valve, and a plenum coupling the pump to the valve. The pump flow is modeled based on the pump speed (or pump motor voltage), the pump inlet air temperature and the pressure ratio across the pump, and the valve flow is modeled based on the pressure ratio across the valve and the valve inlet air temperature. The plenum pressure used in the pump and valve pressure ratios is modeled based on the net plenum airflow and the plenum air temperature. The estimated AIR airflow is useful for managing the air/fuel ratio in the engine exhaust system and enhancing the reliability of AIR diagnostics.

  • Patent number: 7252249
    Abstract: A solenoid-type fuel injector assembly having at least one component formed of stabilized, solenoid-quality ferritic stainless steel. In a preferred embodiment, an austenitic fuel tube is laser-welded to an injector body and to a solenoid pole piece formed of the subject material. The stabilized, solenoid-quality ferritic stainless steel, preferably a free-machining grade thereof, comprises from about 10% to about 35% chromium, and at least one stabilizing element selected from the group consisting of titanium and columbium. Components thus formed are weldable, exhibit soft magnetic properties sufficiently strong for carrying a magnetic flux in a solenoid pole piece, have desired structural and mechanical properties, and reduce the susceptibility of a solenoid-type fuel injector to metallurgical sensitization and intergranular corrosive attack at weld sites.

  • Patent number: 7252056
    Abstract: A target wheel/rotor pre-assembly for a camshaft phaser. A phaser rotor includes a central bore. A target wheel axial extension having a plurality of barbs is entered into the bore to fix the target wheel to the rotor, both axially and rotationally, prior to assembly of the rotor into a phaser stator during manufacture of the phaser. Simple gauge blocks or a fixture can be used to index the target wheel to the rotor such that all such rotor/wheel subassemblies are substantially identical, to a high degree of precision. Alternatively, the axial extension may be formed without barbs, the extension inserted into the rotor bore, and then the extension immobilized as by stamping of the barbs, tack welding, or the like. For another example, the axial extension may be formed as a separate intermediate barbed retainer that engages both the rotor bore and the target wheel.

  • Patent number: 7252059
    Abstract: A closure assembly for a camshaft phaser. A plug or a cap is provided with either a radially-sealing gasket seal or a face-sealing gasket seal, the seal being formed by insertion of the plug into a bore, or by installation of a cap over a neck formed in a cover plate. The closure is provided with a plurality of spaced-apart locking elements, and the plate is provided with a plurality of spaced-apart, radially extending second locking elements in the form of fingers surrounding a central opening. During assembly, the closure is mated to the plate with the first locking elements interspersed with the second locking elements. The closure is rotated to bring the locking elements into locking engagement with each other, preventing counter-rotation of the closure. No threads or torque specifications are required.

  • Patent number: 7253137
    Abstract: A catalyst for preferentially reducing carbon monoxide in a hydrogen stream. The catalyst is formed from a chemical composition including a hexaaluminate, a metal hydroxide and a precious metal. The composition may be disposed on a support or may be extruded or cast into or onto a support. Incorporation of hexaaluminates allows inclusion of metal hydroxides that flux the active precious metal surface at higher temperatures than can aluminum oxide-based catalytic compositions, thereby enhancing resistance of the catalyst and monolithic support and increasing the durability and thermal range of the PROX catalyst. An additional advantage is that lesser amounts of precious metal oxides need be deposited onto the hexaaluminate, while retaining activity similar to aluminum oxide compositions.

  • Patent number: 7251876
    Abstract: A machine for terminating electric cable has a feeding segment that is decoupled from a terminating segment. The feeding segment has two feeders on which electric cable is wound. A length of cable is paid off one feeder and cut to length while another length of cable that has been paid off another feeder and cut to length is terminated at least at one end of the cable. A process for terminating electric cable provides a cable feed comprising a plurality of feeders and pays off a length of cable from one feeder of the cable feed while another length of cable that has been paid off another feeder of the cable feed is terminated at least at one end of the another length of cable. Alternatively lengths of cable are paid off two feeders and accumulated in a buffer segment associated with a feeding segment and a terminating segment. In an alternative process several lengths of cable are cut off and accumulated in a buffer while several other lengths of cable are being terminated.

  • Patent number: 7253722
    Abstract: A diagnostic method for a blind-zone sensing system including leading and trailing passive IR sensors periodically determines a separation distance between coverage areas of the leading and trailing sensors to diagnose sensor alignment. Signals produced by the leading and trailing sensors are sampled and stored over a defined interval of time for processing. A condition in which the sensor coverage areas abruptly encounter a stationary region of cooler temperature is detected when corresponding signal deflections are identified. The elapsed time between the identified signal deflections is measured and used along with an accurate measure of the vehicle speed to compute the separation distance between coverage areas of the leading and trailing sensors.

  • Patent number: 7250322
    Abstract: A linear accelerometer is provided having a support substrate, fixed electrodes having fixed capacitive plates, and a movable inertial mass having movable capacitive plates capacitively coupled to the fixed capacitive plates. Adjacent capacitive plates vary in height. The accelerometer further includes support tethers for supporting the inertial mass and allowing movement of the inertial mass upon experiencing a linear acceleration along a sensing axis. The accelerometer has inputs and an output for providing an output signal which varies as a function of the capacitive coupling and is indicative of both magnitude and direction of vertical acceleration along the sensing Z-axis. A microsensor fabrication process is also provided which employs a top side mask and etch module.
