Abstract: A mixer assembly for mixing an injected reductant with an exhaust gas output from a combustion engine comprises a mixer housing including a wall defining an exhaust passageway having a longitudinal axis. A tubular swirling device housing extends along a first axis substantially transverse to the longitudinal axis. The tubular swirling device includes a plurality of openings through which exhaust gas enters. The exhaust gas within the tubular swirling device swirls about the first axis and exits at an outlet end of the tubular swirling device. A mixing plate is positioned immediately downstream of the tubular swirling device. The mixing plate swirls the exhaust about a second axis extending parallel to the longitudinal axis.

Abstract: A damper system for a vehicle is provided that includes an outer tube, a piston rod, and a piston assembly that is mounted to the piston rod and separates the outer 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 magnetic rotor is fixed to and extends annularly about the outer tube. A stator assembly is coupled to the piston rod by a spherical bearing assembly. The stator assembly includes a plurality of coils that apply an active damping force to the piston rod when energized. The coils can also generate electricity from axial movements of the piston rod relative to the outer tube. One or more glide bearings are disposed radially between the coils and the magnetic rotor in a sliding fit to stabilize the stator assembly.

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: An injector for injecting a reagent includes a first injector body and a second injector body. The first injector body includes an outlet opening. The second injector body includes a reagent tube. The second injector body is movable relative to the first injector body. The injector further includes a valve assembly at least partly enclosed by the first injector body. The valve assembly is configured to selectively dispense the reagent through the outlet opening of the first injector body. The injector further includes a spring member positioned between the first injector body and the second injector body. The spring member is pre-loaded to bias the second injector body towards the first injector body. The spring member is further configured to limit a maximum movement of the second injector body relative to the first injector body in response to expansion of the reagent during freezing.

Abstract: An exhaust aftertreatment system includes a pump configured to circulate a reagent, an injector configured to deliver the reagent into an exhaust stream, a sensor configured to (i) measure an operating parameter of the aftertreatment system and (ii) output a signal that indicates a value of the measured operating parameter, and a control module configured to control the injector based on the signal outputted by the sensor. The control module includes a correction coefficient determination module configured to generate a correction coefficient based on the signal outputted by the sensor. The control module further includes an injector control module configured to receive an injector flow control signal, determine a pulse width modulation (PWM) signal based on at least the injector flow control signal, and generate an injector control signal that controls actuation of the injector based on at least the correction coefficient and the PWM signal.

Abstract: A system includes an engine and an exhaust conduit in communication with the engine. A water separation device has exhaust gas passageways in communication with the exhaust conduit. The water separation device has a substrate and a membrane on the substrate. The substrate has inner walls surrounding the exhaust gas passageways with at least one of the inner walls being common to at least two of the exhaust gas passageways. The membrane is between the exhaust gas passageways and the substrate and has capillary condensation pores extending from the exhaust gas passageways to the substrate.

Abstract: A replacement indicator for a shock absorber includes a pressure sensor which monitors pressure of operating fluid inside the shock absorber. The replacement indicator includes an indicative mechanism operatively coupled with the pressure sensor. The indicative mechanism includes an indicator component coupled to the shock absorber. The indicator component gets displaced relative to an outer surface of the shock absorber when the pressure of the operating fluid drops below a threshold pressure.

Abstract: A damper system for a vehicle including a pressure tube and a piston assembly. A stroke dependent damper assembly is coupled to a piston rod at a position below the piston assembly. A free floating piston positioned in an internal cavity of the stroke dependent damper assembly is longitudinally moveable between retracted, middle, and extended positions. A metering pin extends from the floating piston into a through-bore in a distal end of the stroke dependent damper assembly. An orifice is defined between an inner surface of the through-bore and an outer surface of the metering pin. Longitudinal movement of the floating piston changes the position of the metering pin in the through-bore, which changes the size of the orifice. Fluid flow through the orifice is restricted when the orifice size decreases, which slows down the movement of the floating piston as it approaches the retracted and extended positions.

Abstract: An oxygen separation device includes a substrate and an oxygen ion transport membrane supported on the substrate. The substrate has an air inlet end and a retentate outlet end. An intake air passageway extends through the substrate from the air inlet end to the retentate outlet end. The oxygen ion transport membrane is between the substrate and the intake air passageway and is adapted to separate oxygen atoms from the air in the intake air passageway and to transport the oxygen atoms to the substrate. The oxygen separation device collects the oxygen from the substrate for supply to an internal combustion engine for use as the gas of the gas-fuel mixture.

Abstract: The present disclosure provides a method of producing an insulation preform having graded porosity for an exhaust treatment component of a vehicle. The method includes obtaining a first granular insulating material having a first diameter, a second granular insulating material having a second diameter less than the first diameter, an inorganic binder, and water. The method further includes producing a slurry comprising the first granular insulating material, the second granular insulating material, the inorganic binder, and water. The slurry is introduced into a mold having at least one surface adapted for vacuum extraction. A liquid phase of the slurry is evacuated from the mold using vacuum extraction to produce a moist preform. The moist preform has graded porosity such that a greater concentration of the second insulation material is adjacent to the at least one surface than the first insulating material. The moist preform is heated to produce the insulation preform.
