Abstract: A damper system for a vehicle is provided that includes a damper and actuator. The damper extends longitudinally along a damper axis between first and second damper ends. The actuator is separate and spaced apart from the damper. The actuator extends longitudinally along an actuator axis between first and second actuator ends. The damper and the actuator are arranged next to one another where the actuator axis is spaced from and substantially parallel to the damper axis. The damper and the actuator are positioned within a cylindrical packaging envelope that has a diameter of 300 millimeters or less. The cylindrical packaging envelope is an imaginary cylinder, which may be defined by one or more components of a vehicle's suspension system such as a coil spring or an upper suspension arm. The damper and the actuator are completely contained within the cylindrical packaging envelope.

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 muffler for receiving exhaust gas from a combustion engine may include a shell, an inlet pipe, at least one outlet pipe, one or more baffles, and an internal communication pipe. The inlet pipe may extend through the shell. The outlet pipe may be in fluid communication with the inlet pipe and may be at least partially disposed within the shell. The baffles are disposed within the shell and cooperate with the shell to define a plurality of chambers. The internal communication pipe may be disposed entirely within the shell and may be in fluid communication with the inlet pipe. The internal communication pipe may include an inlet opening and first and outlet openings. The first outlet opening is open to and in direct fluid communication with one of the chambers. The second outlet opening is open to and in direct fluid communication with another one of the chambers.

Abstract: A cover system for a damper includes an outer tube and a piston rod extending from an end of the outer tube. The cover system also includes a dust tube disposed around a portion of the outer tube. The dust tube includes a first end located proximal to the end of the outer tube and a second end opposite to the first end. The dust tube at least partially encloses the piston rod. The cover system further includes a cap connected to the outer tube. The cap is adapted to at least partially cover the first end of the dust tube.

Abstract: A damper includes an inner tube. The damper includes a piston slidably disposed within the inner tube. The piston defines a first working chamber and a second working chamber within the inner tube. The damper also includes an outer tube disposed around the inner tube. The outer tube defines an outer chamber between the inner tube and the outer tube. The damper further includes a cover member mounted on an outer surface of the outer tube. The cover member defines a collector chamber between the outer tube and the cover member. The damper includes a first control valve mounted on the cover member. The damper also includes a second control valve mounted on the cover member and spaced apart from the first control valve.

Abstract: A pressure sensor includes: a housing; a substrate that is fixed within the housing, that includes a first side that is in contact with a fluid of an exhaust aftertreatment system, and that flexes based on a pressure of the fluid; a first voltage divider that is connected between a first reference potential and a ground potential and that varies a first potential based on flexing of the substrate; and a second voltage divider connected in parallel with the first voltage divider between the first reference potential and the ground potential and that varies a second potential based on flexing of the substrate. A pressure control module is configured to selectively switch switches to connect and disconnect different reference potentials to and from an amplifier, to sample an output of the amplifier, and to convert samples of the output of the amplifier into corresponding digital values.

Abstract: A muffler may include a shell, first and second baffles, an inlet pipe, first and second outlet pipes, and a communication pipe. The first and second baffles cooperate with the shell to define first, second and third chambers. The first inlet pipe may extend through the shell and may provide exhaust gas to at least one of the first and second chambers. Exhaust gas in the first chamber exits the muffler through the first outlet pipe. Exhaust gas in the second chamber exits the muffler through the second outlet pipe. The communication pipe may include first, second and third openings. The first opening is in communication with the first chamber. The second opening is in communication with the second chamber. The third opening is in communication with the third chamber. The first and second chambers may be in communication with the third chamber through the communication pipe.

Abstract: A mixer assembly for mixing an injected reductant with an exhaust gas output from a combustion engine includes an outer housing, a tubular inner housing, and an injector. The outer housing includes an outer wall defining an exhaust gas passageway that can receive exhaust gas. The inner housing is disposed within the outer housing and includes a longitudinal axis, a first end, a peripheral wall, and an outlet. The peripheral wall is at least partially formed by wire mesh. The outlet is disposed at a second end of the inner housing opposite the first end of the inner housing. The injector is fixed to the inner or outer housing to dose the reductant into the interior of the inner housing. The wire mesh includes openings to receive at least a portion of the exhaust gas. The outlet of the inner housing discharges a mixture of exhaust gas and reductant.

Abstract: An exhaust after-treatment system and a method for treating an engine exhaust that each utilize a filter for removing biuret from an aqueous urea exhaust treatment fluid. The filter includes a filter element that includes an adsorbent material configured to adsorb the biuret from the aqueous urea exhaust treatment fluid, and includes a biuret conversion catalyst impregnated in the adsorbent material that is configured to convert the biuret into a material useful for exhaust after-treatment or into a material that is innocuous to an exhaust after-treatment system.

Abstract: A urea reagent exhaust treatment fluid configured for use in treating an exhaust produced by an internal combustion engine comprising water, an amount of urea that is about 32.5 wt %, and an amount of biuret that is at most 0.09 wt %, and a method for manufacturing an aqueous urea reagent exhaust treatment fluid that includes feeding an aqueous urea exhaust treatment fluid including biuret to a filter including a filter element including an adsorbent material having a biuret conversion catalyst. The aqueous urea exhaust treatment fluid is filtered using the filter element by adsorbing the biuret from the aqueous urea exhaust treatment fluid with the adsorbent material, and converting the biuret into a material useful for exhaust after-treatment or into a material that is innocuous, wherein an amount of the biuret remaining in the aqueous urea exhaust treatment fluid after the filtering is at most 0.09 wt %.
