Abstract: A snap-action valve assembly for an exhaust system and a method for manufacturing the same is provided. The valve assembly includes a first conduit and a second conduit that is partially received in the first conduit. A valve flap is disposed within the first conduit for controlling exhaust flow. A shaft supports the valve flap in the first conduit for rotation between open and closed positions. The first conduit has first and second slots, each extending from an open slot end to a closed slot end. First and second bushings subassemblies supporting the shaft are disposed within the slots between the second conduit and the closed slot ends. Each of the first and second bushing subassemblies includes an alignment system in the form of protrusions that limit insertion of the first and second bushing subassemblies into the first and second slot to a single orientation.

Abstract: A damper system for a vehicle is provided that includes including a pressure tube, a piston rod, and a piston assembly that is mounted to the piston rod and separates the pressure tube into first and second working chambers. A valve assembly, mounted to the piston assembly, controls fluid flow between the first and second working chambers. A frequency dependent damper assembly, coupled to the piston rod at a position below the piston assembly, includes a plunger sleeve that is longitudinally moveable to transmit an adaptive force to a valve assembly. A plunger travel limiter, positioned longitudinally between the frequency dependent damper assembly and the valve assembly, contacts the plunger sleeve and prevents the plunger sleeve from moving further towards the piston assembly to limit the magnitude of the adaptive force applied to the valve assembly.

Abstract: A mixer assembly for treating exhaust with an injected reductant as the exhaust flows through an exhaust gas passageway includes a tubular shell and a rod. A first end and a second opposite end of the rod are fixed to the shell. The rod has a serpentine shape with a plurality of parallel extending portions interconnected by curved portions. The curved portions are positioned proximate an inner surface of the shell such that the rod traverses the exhaust passageway. The mixer assembly is positioned such that the rod is directly impinged by reductant injected into the exhaust gas passageway.

Abstract: A shock absorber includes a pressure tube forming a working chamber. A reserve tube is concentric with and radially outward from the pressure tube. A baffle is positioned radially outward from the pressure tube. A reservoir chamber is formed between the reserve tube and the baffle. A piston is attached to a piston rod and slidably disposed within the pressure tube. A rod guide is attached to the pressure tube and supports the piston rod. An electromechanical valve is positioned within the rod guide. A plurality of non-linear passageways are disposed between the baffle and at least one of the pressure tube and the reserve tube for transporting fluid between the electromechanical valve and the reservoir chamber.

Abstract: A shock absorber for a vehicle is disclosed which has a pressure tube defining a fluid chamber, a piston rod, and a piston disposed within the fluid chamber, and carried on the piston rod, which divides the fluid chamber into upper and lower working chambers, and which has a plurality of passages extending between the upper and lower working chambers. A valve disc assembly controls a flow of fluid, and includes a spring disc. The spring disc has a non-symmetrical circumferential shape which enables a stiffness of the valve disc assembly to be tailored so that it begins to open at a first peripheral point, and continuously gradually opens about a non-symmetrical circumferential path until reaching a second peripheral point adjacent the first peripheral point.

Abstract: A particulate sensor assembly may include a particulate sensor and a sensor housing. The particulate sensor may be configured to measure a quantity of particulate matter in a stream of exhaust gas from a combustion engine. The sensor housing may receive the particulate sensor and may include a cavity in which the particulate sensor is exposed to the exhaust gas. The cavity may be defined by a porous structure through which the exhaust gas may flow. The porous structure may filter a predetermined amount of particulate matter from the exhaust gas as the exhaust gas enters the cavity.

Abstract: A mixing system for an exhaust aftertreatment system includes a first mixing device having a plurality of first auger blades and an inlet having a first cross-sectional area. A second mixing device is separate and downstream from the first mixing device and includes a second auger blade. The second mixing device includes an inlet having a second cross-sectional area greater than the first cross-sectional area. A plurality of flow paths created by the first mixing device are recombined into a single flow path between the first and second mixing devices. A longitudinal center line of the first mixing device is offset from a longitudinal center line of the second mixing device.

Abstract: A damper system may include an electrically adjustable hydraulic shock absorber having an electromechanical valve and a damper controller. The damper controller may include a solenoid driver circuit electrically coupled to the electromechanical valve, and disposed at the shock absorber. The solenoid driver circuit may be operable to drive the electromechanical valve in an open state in which hydraulic fluid flows between a pressure tube and a reserve tube. The solenoid driver circuit may include a plurality of transistors that are operable to generate a first current to place the electromechanical valve in the open state and a second current less than the first current to hold the electromechanical valve in the open state.

Abstract: An exhaust gas treatment system for reducing emissions from an engine includes an exhaust conduit adapted to supply an exhaust stream from the engine to an exhaust treatment device. The conduit includes an aperture. An injector injects a reagent through the aperture and into the exhaust stream. A flow modifier is positioned within the exhaust conduit upstream of the injector. The flow modifier increases the velocity of the exhaust gas at a predetermined location within the conduit relative to the injected reagent.
