Abstract: A method of drilling and lining a wellbore includes operably coupling a support member to a drilling device, an expansion cone configured to expand a tubular member, an actuator configured to pull the expansion cone through the tubular member, a releasable locking device configured to limit displacement of the tubular member relative to the actuator during actuation. The drilling device is disposed below the expansion cone and the expansion cone is disposed at a lower end of the tubular member. The method further includes locking the locking device. After locking the locking device, a wellbore is drilled to have a diameter greater than an outside diameter of the tubular member. After the drilling, the actuator is actuated to pull the expansion cone towards the locking device to expand at least a portion of the tubular member into contact with the drilled wellbore. The method further includes releasing the locking device and removing the drilling device through the expanded tubular member.

Abstract: The invention is directed to a method for setting an occupant classification system threshold for a vehicle occupant detection system, the method comprising collecting occupant classification system data for a seat, the data being indicative of occupant weight, analyzing the data to determine where a separation exists between an occupant for which a restraint should be suppressed and an occupant for which the restraint should be deployed, and analyzing the data to determine a worst case child suppression weight and shape, which is based at least on where the separation exists. The worst case child suppression weight and shape define the occupant classification system threshold.

Abstract: A method for improving NOx conversion efficiency of a Nox-reducing catalyst by determining an accurate amount of reductant required is presented. The method includes calculating an initial reductant injection amount based on a steady state amount of NOx in the engine feedgas and adjusting the initial amount to compensate for transient NOx emissions. The compensation is initiated in response to an engine transient, such as impending acceleration or deceleration. This method further results in improved vehicle fuel economy.

Abstract: A wheel support knuckle and trailing arm assembly that is attached to a toe link of a vehicle suspension system. The trailing arm assembly is formed by a blade member and a reinforcement member. The wheel support knuckle defines an axle bore and includes an integrally formed upper link receptacle and an integrally formed brake caliper track. The toe link is retained on the trailing arm assembly by a clevis formed by a transverse wall formed in the blade member and a parallel transverse wall formed in the reinforcement member. An alternative embodiment discloses a one-piece trailing arm that defines a clevis for connection to the toe link between a transverse wall and a tab that extends parallel to the transverse wall. A method of making cast wheel support knuckle and stamped trailing arm assembly is also disclosed.

Abstract: A method for controlling operation of a transfer case clutch in a motor vehicle driveline controlled by an engine throttle having a variable position. The transfer case transmits rotating power to a primary power path and to a secondary power path in response to an electric current duty cycle applied to a coil that actuates the clutch. The method includes the steps of determining that a current vehicle speed is less than a reference vehicle speed; determining that the engine throttle position is in a reference throttle position range; determining that a change in vehicle speed is greater than a reference change in vehicle speed; using a current magnitude of torque in the driveline to determine a desired duty cycle for the coil; and applying a duty cycle of the desired magnitude to the coil.

Abstract: A side impact airbag system is disclosed that is stored behind cover panels provided on the A-hinge pillar, rocker, and C-body lock pillar. The airbag is stored in a receptacle until it is inflated by an inflator. The inflator inflates the airbag that is connected between fore-and-aft spaced anchoring points. When the airbag is in a deployed position, it is located between a seat and door of the vehicle. The deployment height of the airbag is controlled by tethering side shield panels that are secured between the airbag and the vehicle. The tethering side shield panels are not inflated by the inflator but are pulled to a taut condition as a result of the deployment of the airbag.

Abstract: A tailgate structural configuration accommodates the housing of a supplemental tailgate internally within the tailgate. The tailgate is formed with an outer panel and an inner panel to define an internal cavity. The upper portion of the tailgate includes a C-channel frame member connected to both the inner and outer panels to support guide tubes telescopically housing the supplemental tailgate. To enhance structural stability, the tailgate further includes one or two transversely oriented strainers having formed therein flanged depressions or openings for the passage of the guide tubes vertically therethrough. Each guide tube is affixed to a mounting bracket that is detachably connected to the C-channel to support the guide tube within the tailgate. Positioning pins mounted on the mounting bracket affixed to the guide tubes engage locator holes in the C-channel for positioning the supplemental tailgate.

Abstract: A method and apparatus for forming a sheet of ductile material by superplastic forming is disclosed. The method is directed to first creating a pre-form by mechanical forming in which the pre-form is created with a die and punch. Thereafter the pre-form is subjected to gas pressure in a forming cavity to complete formation of the part. A metallic gasket is provided to ensure that no pressurized gas escapes from the forming cavity.

Abstract: A method for controlling a variable event valvetrain during engine start and stop is presented. According to the method, valve lift and/or timing can be adjusted to reduce the amount of oxygen pumped into an exhaust gas after treatment system. The method can reduce engine emissions, at least during some conditions, since there may be less oxygen available to alter the operating state of the exhaust gas after treatment system.

Abstract: A variable compression ratio piston (26) and connecting rod (18) assembly for an internal combustion engine (14) includes an eccentric bushing (28) that carries a piston pin bushing (42) and contains a journaled portion (48) held in the rod bore (24) of the connecting rod (18). The eccentric bushing (28) can be selectively rotated between either of two angle adjusted positions to effect a change in the height of the piston (26) relative to the connecting rod (18), and thus change the compression ratio of the assembly. A latch (50) mechanism is actuated by oil jets (90, 91) external to the connecting rod (18). The latch (50) includes bolts (54, 56) with tapered tips that seat in oblong holes (60, 62) in a flange plate (58) to reduce destructive lash. A resilient stop post (80) bears the brunt of stresses associated with stopping the flange plate (58) during switching events to protect the latching bolts (54, 56).

Abstract: An air diffuser (20) for an air intake system of an internal combustion engine. The air intake system includes a throttle body (22) up stream from an intake manifold (24), with the air diffuser (20) mounted between them. The air diffuser (20) includes vanes (62,64) extending into its main bore (52) in order to diffuse and redirect the air flowing from the throttle body (22) into the intake manifold (24). An EGR assembly (70) is mounted to the manifold (24) just downstream of the inlet to the manifold (24). The diffusion and redirection of the air reduces the noise emanating from the intake manifold (24) for particular engine operating conditions, and also reduces the backflow of EGR gasses into the throttle body (22).
