Abstract: A pressure operable device for an integrated pressure management apparatus. The pressure operable device includes a poppet moving between a first configuration permitting fluid communication between first and second ports of the integrated pressure management apparatus, and a second configuration preventing fluid communication between the first and second ports. A spring biases the poppet toward the second configuration, and a diaphragm operably engages the poppet to move the poppet toward the first configuration.

Abstract: An active noise attenuation system for an air induction assembly is operably connected to an engine that generates a low frequency noise having a noise profile defining a peak noise. The system has an air inlet duct housing with an inlet and an outlet connected to the engine. A resonator is supported by the housing and is positioned between a speaker assembly and the engine to attenuate the peak noise resulting in an attenuated low frequency engine noise. A microphone senses the attenuated low frequency engine noise and generates an attenuated low frequency engine noise signal. A controller receives and phase shifts the signal and sends the signal to the speaker to generate a sound field to cancel or reduce the attenuated low frequency engine noise signal.

Abstract: A system and method for detecting leakage from a evaporative emission space of an automotive vehicle fuel system. A reciprocating pump is operated in a pressurizing mode to build pressure in the space toward a nominal test pressure. The pressurizing mode involves operating the pump in a repeating cycle wherein the pump operates alternately in an accelerated pumping mode and a natural frequency pumping mode. During the pressurizing mode, a characteristic of successive occurrences of the natural frequency pumping mode indicative of pressure in the space is measured. The number of times the cycle repeats is counted and compared to a predefined reference.

Abstract: A method is disclosed for manufacturing a commutator adapted to be mounted on a shaft of an electric motor for cooperation with electrical contacts of the motor, wherein a support member is molded from an electrically insulating material, the support member having a major outer surface portion divided into subsections of lesser area by a plurality of rib members extending upwardly from the outer surface portion. A sheet of electrically conductive material with minimum waste, is cut into commutator segments of predetermined shape and dimensions preferably by a stamping process for attachment to the outer surface portions of the subsections. The commutator segments are then adhesively attached to the outer surface portions of the subsections such that the segments form commutator surfaces interrupted by the rib members, with the upper surface of each segment being slightly higher than the upper surface of each of the adjacent rib members.

Abstract: A lost core molding assembly (20) according includes a manifold (22) which minimizes adherence between a molten alloy and the manifold. The manifold (22) receives a heated fluid from a source and circulates the heated fluid through a heated fluid passage (66.) The heated fluid passage (66) arrangement assures that the heated fluid maintains the molten alloy in an even molten condition thereby reducing degradation of the molten alloy prior to injection into the mold.

Abstract: A fan shroud structure 10 including a shroud body 12 having a pair of opposing first sides 14 and a pair opposing second sides 16. The first sides 14 are joined with the second sides 16 at corners 18 so as to form a box-like configuration defining an interior space 20. The shroud body has a front end constructed and arranged to be disposed adjacent to a condenser and a back end constructed and arranged to be disposed adjacent to a radiator. Generally annular wall structure 26 is within the interior space and is constructed and arranged to receive blades of a fan within bounds thereof. Vortex preventing structure 40 is provided in each corner near the back end. The vortex preventing structure is constructed and arranged to prevent large scale eddy current generation of air in the corners as air enters the radiator. Air deflecting structure 50 is provided in each corner near the front end.

Abstract: An internal combustion engine exhaust emission control system has a module for conveying exhaust gas from an engine exhaust system to an engine intake system. A valve selectively restricts the flow path. A pressure sensing passage communicates a pressure sensing port of a pressure sensor to the flow path. The pressure sensing passage comprises a tube having an end portion passing through a through-hole in a side wall of the flow path. In one embodiment, an open free end of the tube is disposed within the flow path in spaced relation to the side wall opposite an orifice that creates a pressure drop for obtaining a flow measurement using pressure sensed via the tube as one input. In another embodiment, the open free end of the tube is disposed flush with the side wall opposite a nozzle.

Abstract: An intake manifold for an engine is provided that includes a housing having a passageway carrying blow-by gases from an engine crankcase. A valve body housing having a cavity is defined by a portion of the housing. The valve body housing has a vacuum side and a blow-by gas side. The blow-by gas side is in fluid communication with the passageway. A positive crankcase ventilation valve is disposed within the cavity and permits the blow-by gases to flow from the passageway through to the vacuum side when in an open position. A cap is preferably secured to the housing for sealing the positive crankcase ventilation valve within the cavity. Preferably an oil separator is also integrated into the intake manifold to separate the oil from the blow-by gases.

Abstract: A method and apparatus is provided for driving a throttle blade about an axis of rotation between maximum and minimum airflow positions.

A position sensor is also mounted within the bore to monitor the position of the blade relative to the body.

Abstract: A method and sensor or sensor subsystem permit improved evaporative leak detection in an automotive fuel system. The sensor or sensor subsystem computes temperature-compensated pressure values, thereby eliminating or reducing false positive or other adverse results triggered by temperature changes in the fuel tank. The temperature-compensated pressure measurement is then available for drawing an inference regarding the existence of a leak with reduced or eliminated false detection arising as a result of temperature fluctuations.
