Abstract: An injector for injecting a reagent includes an axially translatable valve member positioned within a housing. A flux sleeve is surrounded by a coil of an electromagnet. A pole piece defines a return passageway for reagent to flow. A filter surrounds the pole piece and includes a cage and a mesh fixed to the cage. The cage includes a deformable first seal biasedly engaging an outer surface of the pole piece. The cage includes a second seal biasedly engaging the housing. The first and second seals define a closed volume such that all of the reagent flowing through the injector passes through the mesh.

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.

Abstract: A hydraulic actuator circuit is disclosed for use with first and second shock absorbers, which each may include a piston disposed within a housing. The piston helps define upper and lower working chambers. The circuit may have a motor, a first pump, driven by the motor, and is associated with the first shock absorber and the motor. A second pump, driven by the motor, may be associated with the second shock absorber. A first accumulator communicates with both of the first and second pumps. A first switch valve may assist in controlling fluid flow into the chambers of the first shock absorber. A second switch valve may assist in controlling fluid flow into the chambers of the second shock absorber.

Abstract: An exhaust gas aftertreatment system for a vehicle includes a cylindrical inner shell, a cylindrical outer shell, an inner end cap, a metal mounting member, and an outer end cap. The inner shell is configured to guide exhaust gas. The outer shell forms a first gap to the inner shell. The inner end cap encloses an open end of the outer shell. The inner end cap includes a first axially-extending lip. The inner end cap is fixed to the inner shell. The outer end cap is fixed to the inner end cap. The outer end cap includes a second axially-extending lip. The outer end cap and the inner end cap cooperate to encapsulate the mounting member. The first axially-extending lip is sandwiched between the outer shell and the second axially-extending lip.

Abstract: A damper system for a vehicle is provided that includes a pressure tube and a piston assembly separating the pressure tube into first and second working chambers. A frequency dependent damper assembly, coupled to a piston rod at a position below the piston assembly, includes a plunger sleeve that is longitudinally moveable to transmit an adaptive force to a first valve assembly mounted to the piston assembly. The frequency dependent damper assembly includes first and second accumulation chambers that are separated by a floating piston. A second valve assembly, carried on the floating piston, controls fluid flow between the second accumulation chamber and the second working chamber. A bleed channel in the floating piston allows fluid flow between the first and second accumulation chambers, which reduces the adaptive force the plunger sleeve applies to the first valve assembly during high frequency, low velocity rebound inputs.
