Abstract: The disclosure allows a short runner valve or manifold tuning valve type manifold tuning device to retain sufficient force on the valve assembly in its closed state to eliminate any vibration or chatter from the system under normal engine operation. The disclosure also allows the device to be “pulsed” to the open or closed position; thus no electrical power is required to keep the system in one state. This is especially useful if activated times are extended due to certain engine operating conditions.

Abstract: An active noise control system (100) and method compensates for changes in a microphone output to maintain accurate noise control. A calibration signal reflecting a desired microphone output is generated and stored in an active noise control module (106). During operation, the active noise control module (106) compares an actual microphone output signal with the calibration signal and compensates for any changes in the actual output signal before any noise compensation or cancellation function occurs.

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: An intake manifold includes a plenum volume 14 mounted for movement within a housing 20 in response to a drive system 22 to define an effective runner length. A multiple of deformable runner passages 18 include a flexible section 26 such that as the plenum 14 extends and retracts within the housing 20, the flexible section 26 accommodates the difference in length while the housing 20 provides structural support therefor. An intake conduit 12 likewise includes a flexible section 26 to accommodate movement of the plenum 14. In operation at low engine speeds, the plenum 14 is driven to extend the deformable runner passages 18 to increase the length between the plenum 14 and the engine cylinders 16. As the engine speed increases, the plenum 14 is driven to shorten the deformable runner 18 for maximum speed operation.

Abstract: A rubber hose of an air supply assembly is secured to a resonator by an inserted internal tube. A tapered insertion end of the internal tube is inserted into the rubber hose and slides along an angled surface of the rubber hose. The tapered insertion end presses the rubber hose against a hose neck of the resonator to retain and seal the rubber hose. A retention end of the internal tube secures the tube to the resonator. The retention end includes a recessed portion positioned between a pair of flanges. The tube neck of the resonator engages the recessed portion, the flanges securing the internal tube in place.

Abstract: A vehicle component assembly (20) has a component body (22) that includes a first portion (30) and a second portion (32). A selected section (26) of a wire harness (24) is secured into the component body (22) using an adhesive (28). In one example, the adhesive (28) surrounds the conductor (25) of the wire harness (24). The adhesive (28) secures the component body portions (30) and (32) together.

Abstract: An air introduction system (10) provides an active noise control system which includes a speaker assembly (28) in which the speaker support ring (36) is mounted to a speaker housing (32) without fasteners. In one speaker assembly, the speaker housing includes a plurality of extensions (40) which extend radially from an outer periphery of the speaker housing (32). The speaker support ring includes an edge (42) which at least partially surrounds the extensions (40). In another speaker assembly, the speaker support ring (50) includes a plurality of apertures (52) through a flange (54) which closely fits a speaker housing (32). The housing edge (54) and the speaker protection cone edge (56) are heated to a melting point of the material and the speaker support ring (50) is sandwiched therebetween. Heated material from the housing edge and the speaker protection cone edge pass through the apertures (52) to provide an effective bond therebetween.

Abstract: An engine noise control system (100) controls engine noise in multiple engine operating modes by controlling a size of an air inlet (104) with a movable valve. An actuator (114) moves the valve (112) between an open position and a closed position depending on the engine operating mode, to control the amount of air travelling into an air cleaner. The actuator (114) is coupled to an engine cylinder de-activation unit (200) to link the valve operation to the engine operating mode. When the engine is operating in a low-power mode, which requires less air, the actuator (114) moves a cable drive (204), which rotates an actuation lever (208) that turns the valve (112) into a closed position. When the engine is operating in a high-power mode, the actuator (114) moves the cable drive (204) to move the valve (112) to an open position.

Abstract: An active noise control system includes a speaker located within an enclosure within a vehicle body component. The speaker enclosure is typically located forward of a vehicle wheel well. An elongated transmission member communicates canceling noise from the speaker enclosure over the wheel well to an outlet adjacent the firewall. The elongated transmission member focuses and directs cancellation noise toward the firewall and bypasses the wheel well and any restriction created thereby.

Abstract: An air cleaner includes a slide retention structure which engages a sliding resonator volume. The volume slides along the slide retention structure into an assembled position. Once assembled, a tuning tube engages an aperture in the volume, the volume and the resonator assembly reducing noise produced by the engine. A flexible seal is positioned around the aperture to acoustically seal the resonator volume to the tuning tube. An air cleaner cover is secured to the box by a lock plate. To lock the cover to the box, the lock plate is slid so that a plurality of wedges on the plate are forced under hooks on the box, securing the cover to the box. A side opening located proximate to the wedges allow the lock plate to slide so that the hooks do not hinder the movement of the lock plate.

Abstract: A resonator provided for air system that includes a body defining a passageway. A wall is disposed within the chamber and the wall and the chamber are movable relative to one another to define a length and a volume of the cavity. The length and the volume of the cavity define a noise attenuating frequency. By moving the wall and chamber relative to one another the noise attenuating frequency may be changed as the frequency changes during the engine operation. The drive mechanism moves the wall in the chamber relative to one another to change the noise attenuating frequency. The chamber may be a branched type resonator or an inline type resonator. Accordingly, the above described invention provides a resonator that may be adjusted during engine operation to attenuate noise over a variety frequencies.

Abstract: The subject invention is a linkage assembly for an electronically controlled throttle (ETC) that provides for the precise setting of a limp home engine speed for a vehicle. Essentially a controlled amount of movement is attained between a closed position and a limp home throttle position. A throttle valve is attached to a first shaft and rotates to regulate air intake. The first shaft is attached to a sector gear. The sector gear is driven by the ETC. A stop bracket limits the amount that the sector gear can close the throttle valve. The stop bracket defines an opening, and a cam is disposed within the opening. A spring biases the stop bracket against the cam. Normally, the ETC can overcome the spring and the stop bracket is forced against the cam such that stop bracket contacts the cam to define a closed throttle position. Of course, when operational the ETC can drive the valve to open position as demanded by the vehicle.
