  • Patent number: 6612162
    Abstract: A method of determining the phase angle of an internal combustion engine camshaft relative to a crankshaft of the engine, which significantly reduces the computational burden compared to conventional methods. The cam and crankshaft position pulses are identified by corresponding clock values, and the cam phase angle relative to the crankshaft is determined by computing a simple ratio of first and second time intervals based on the clock values, and multiplying the ratio by a known angle. One of the time intervals is defined by a time difference between successive crankshaft and camshaft pulses, while the other time interval is defined by a time difference between successive crankshaft pulses. The known angle is the angle of crankshaft rotation between the successive crankshaft pulses. The cam phase angle velocity is obtained by determining a change in cam phase angle, and dividing by the intervening time interval.

  • Patent number: 6605264
    Abstract: The present invention relates to high oxygen ion conducting/oxygen storage (OIC/OS) materials, a catalyst employing the OIC/OS materials, and a method for converting hydrocarbons, carbon monoxide and nitrogen oxides using the catalyst. The OIC/OS materials have significantly higher oxygen storage capacity than that predicted based on Ce content due to the unexpected high and facile redox activity of the added niobium. These materials are further characterized by having a tetragonal crystalline structure under oxidizing conditions (in air) up to about 1,200° C. and a cubic crystalline structure in reducing conditions (5% hydrogen) up to about 1,000° C. for 24 hours. These materials comprise, based upon 100 mole % of the metal component in the material, up to about 95 mole % zirconium, up to about 50 mole % cerium, about 0.5 to about 15 mole % rare earth metal(s), alkaline earth metal(s) or a combination thereof, and about 0.5 to about 15 mole % niobium.

  • Patent number: 6605912
    Abstract: A three region control strategy for a permanent magnet motor is presented. In a first control region, the permanent magnet motor is operated at, a 120° conduction square wave mode at reduced phase current, and below a no-load speed. The motor phase current commutation causes eddy current losses in the rotor magnets and core which are insignificant due to the low phase currents and relatively low rotor speed. Meanwhile, the inverter switching losses are kept low as two switches are in use (on/off) for each current commutation during the 120° conduction mode. In a second control region, the permanent magnet motor is operated at a 180° conduction sinusoidal wave mode with high phase currents. The 180° conduction sinusoidal wave mode minimizes the commutation loss. In a third control region, the permanent magnet motor is operated above its no-load speed or in a field weakening mode.

  • Patent number: 6591497
    Abstract: A catalytic converter is constructed by measuring a substrate to be placed within the outer shell or can, wrapping the substrate in a selected mat and loading the package (mat and substrate) into the can. The can is larger than it will be at completion of manufacture to render such loading easier. Subsequent to loading, the measurement of the substrate is used to direct the degree to which the can is reduced in outside dimension such that a selected annulus is created between the substrate and can, said annulus being occupied by said mat.

  • Patent number: 6588400
    Abstract: A multi-strike throttle minimum learning system compares a signal received from at least one throttle position sensor to a predetermined minimum throttle position range based on throttle system component tolerances. A possible throttle obstruction is indicated when all of the sensor signal minimum values are outside the predetermined minimum range. In this case, the system deactivates electrical power for a predetermined delay period and then initiates another learn attempt in an effort to overcome the obstruction. This cycle is repeated until a valid throttle minimum position is detected, the number of learn attempts reaches a preset maximum, or a sensor fault is detected. If a valid throttle position minimum is detected within the allowed number of learning attempts, normal engine startup proceeds; otherwise, appropriate fault codes are communicated to the balance of the engine management system and, ultimately, to the operator.
