Abstract: A control system for an engine capable of operating on more than one type of fuel includes an engine control unit that determines a default fuel volume to be injected into the engine based on relevant engine parameters and characteristics of a default fuel type. A default mass fuel flow rate is derived from the default fuel volume and relevant engine parameters. The actual mass fuel flow rate into the engine is inferred from the mass air flow rate into the engine and the exhaust gas air-to-fuel ratio, which is determined using a wide range oxygen sensor. A fuel correction factor is calculated from the default mass fuel flow rate and the inferred mass fuel flow rate. The fuel correction factor is used to increment or decrement the default fuel volume in a subsequent fuel injection cycle thereby incrementing or decrementing the inferred mass fuel flow rate toward the default mass fuel flow rate.

Abstract: A two piece wheel hub assembly includes a hub cartridge assembly and a vehicle-mounted carrier. The cartridge assembly can be readily attached to and removed from the carrier without removal of the carrier from the vehicle.

Abstract: A wheel assembly for connection to an onboard tire inflation device includes an inboard rim part, an outboard rim part, a rim base on at least one of the parts and a wheel mounting portion. The wheel mounting portion includes a first passageway extending from an inner opening in the wheel mounting portion to an opening in the rim base. An adapter is mounted to the wheel mounting portion of the wheel and extends at least partially into the inner opening of the wheel in one embodiment, the adapter includes second and third passageways, a circumferential groove in communication with the third passageway, and a valve seat. A valve is mounted to the valve seat. The adapter may include a spindle seat, and the other end of the second passageway opposite the valve seat terminates in an opening in the spindle seat. A seal member may be located in an annular groove formed in the spindle seat around the opening.

Abstract: An exhaust control system for an internal combustion engine having a plurality of actuators wherein each actuator controls a predetermined engine parameter. A plurality of sensors are also associated with the engine and each sensor provides an output representative of an engine operating condition. The control system includes a PID controller associated with each actuator and in which each PID controller has an input, an output and a feedback between the input and the output. A distribution function circuit is operatively connected in series with the inputs of the PID controller. The distribution function circuit receives an error signal representative of the difference between a target value and an actual value of one or more engine operating conditions, previously determined control factor values and the feedback from each PID controller as input signals. The distribution function circuit varies the input to each PID controller as a function of the distribution function input signals.

Abstract: A frame rail assembly configured for use in various applications, including automotive vehicles. The frame rail assembly includes two rail portions. The rail portions include apertures each encompassed by a mounting boss. In addition, the frame rail includes spacers sized and configured to receive the mounting bosses in a snug fit to help with alignment. The spacers include at least one dimple in order to guide a mounting bolt though the apertures. The mounting bolt may be employed to hold the frame rail assembly together and attach other components to the frame rail assembly.

Abstract: A connector for armored electrical cable apparatus which includes a body having a central bore. The body has a generally cup shaped seat disposed in generally aligned relationship to the bore and the body has external threads disposed on the external surface thereof. A dual finger member which is generally cylindrical and has a first plurality of axially extending fingers disposed about the circumferential extent of the generally cylindrical member and a second plurality of axially extending fingers disposed about the circumferential extent of the generally cylindrical member. The free ends of all of the first plurality of axially extending fingers are disposed at a first axial extremity of the generally cylindrical member and the free ends of all of the second plurality of axially extending fingers are disposed at a second axial extremity of the generally cylindrical member. A nut dimensioned and configured for engagement with the threads on the body.
