  • Publication number: 20150256065
    Abstract: A method for generating a pulse width modulation (PWM) control signal includes generating a sawtooth ramp signal at a first frequency under standard operating conditions using a ramp generator, generating a PWM square wave having a rising edge at a falling edge of the sawtooth ramp signal and a falling edge when the sawtooth ramp signal exceeds an error threshold, adjusting the frequency of the sawtooth ramp in response to a changed operating parameter of the ramp generator, and adjusting a peak input voltage of the ramp generator simultaneous with adjusting the frequency of the sawtooth ramp, thereby preventing one of a voltage overshoot and a voltage undershoot.

  • Publication number: 20140054394
    Abstract: A reductant delivery unit (RDU) delivers supplied reductant (aqueous urea solution) to the engine exhaust system. The delivered reductant is transformed into ammonia which then reacts with the exhaust oxides of nitrogen in a catalytic environment to produce nitrogen and H20. The reductant must be metered to coincide with the amount of NOx present in the exhaust, and also present sufficient spray quality of the delivered fluid to promote good mixing of the ammonia with the exhaust gas. The RDU is a liquid-cooled, making the RDU suitable for very high temperature environment applications.

  • Patent number: 8528322
    Abstract: A reductant delivery unit (10?) for selective catalytic reduction (SCR) after-treatment for vehicles includes a fluid injector (12) having a fluid inlet (24) and a fluid outlet (25) with the fluid inlet receiving a source of urea solution to be sent through the fluid outlet. Movable inlet cup structure (16?) communicates with the inlet of the fluid injector. A shield (18?) is fixed with respect to the fluid injector and surrounds at least portions of the fluid injector and the inlet cup structure. A spring (26) is engaged between a portion of the inlet cup structure and the shield. When the urea solution freezes in the fluid injector and expands near the fluid inlet of the injector, the inlet cup structure moves toward the injector inlet to accommodate the frozen urea solution, with the spring returning the inlet cup structure to an initial position once the frozen urea solution melts.

  • Patent number: 8485008
    Abstract: An automotive key fob includes a leaf-style spring positioned within the key fob so that, while a removable key is inserted into the key fob, the removable key engages, and at least partially collapses, the spring thereby reducing movement of the key within the key fob and thereby reducing noise associated with movement of the key within the key fob. The leaf-style spring may be positioned in a spring-surrounding pocket within an external housing of the key fob. The spring-surrounding pocket may be at least partially defined by a wall having a height that is less than a height of the leaf-style spring while the spring is installed within the key fob.

  • Patent number: 8479710
    Abstract: Coupling structure (10) for coupling a fuel injector to a fuel rail (16) includes a fuel injector receiving cup (14) having an outer wall (22) and an interior space (24). The cup includes slot structure (26, 28) through the outer wall. Clip structure (30, 32) has a base (31) and a wall (40) extending transversely from the base. The base is received in the slot structure and extends into the interior space so that a portion of the base engages the fuel injector to limit movement thereof both axially and radially with respect to the receiving cup, with the wall being disposed adjacent to a portion of the outer wall of the receiving cup. A retainer (41) engages the wall of the clip structure to secure the clip structure to the receiving cup.

  • Publication number: 20130160738
    Abstract: Improved throttle body assemblies are described. More particularly, throttle body assemblies having improved throttle position sensor assemblies are described. In one aspect, a throttle body assembly for providing controlled aspiration to an engine is described. The assembly comprises a throttle body housing defining a throttle bore for receiving a throttle plate. The throttle plate is actuatable by an electric motor. The assembly further comprises a throttle position sensor configured to monitor positions of the throttle plate. The throttle assembly further comprises an electric discharge path formed between the throttle position sensor and the throttle body housing, wherein the electric discharge path substantially prevents the accumulation of residual electric charge across the throttle position sensor.

  • Publication number: 20130160735
    Abstract: Throttle body assemblies having improved throttle position sensing assemblies and a method of integrating a throttle position sensor assembly with a throttle body assembly are described. The method comprises the steps of: i) press-fitting a sensor element onto a shaft of a throttle plate of a throttle body assembly; ii) engaging one or more inwardly extending members of the sensor element with one or more recessed portions formed on the shaft of the throttle plate; and iii) disposing an inductive rotary position sensor proximate the sensor element, wherein the press-fit engagement and one or more inwardly extending members limit axial and rotational movement of the sensor element with respect to the throttle plate, and wherein the inductive rotary position sensor detects a relative position of the sensor element for the purpose of ascertaining a position of the throttle plate.

  • Publication number: 20130139792
    Abstract: A vapor management system (10) includes a sense tube (47) disposed in a fuel tank (12). A differential pressure sensor (17) has one side connected to the sense tube and another side connected to a vapor cavity so that the pressure sensor can measure a differential pressure (DP) between a volume of the vapor cavity and a volume of the sense tube containing liquid fuel. A temperature sensor (26) is in the vapor cavity. A processor 1) receives DP and T measurements at certain time intervals to determine the temperature at time zero (T0), the differential pressure at time zero (DP0), the temperature at a certain time (Tt), and the differential pressure at a certain time (DPt), and 2) when (Tt-T0) is greater than a certain value, compares DPt to a certain differential pressure value.
