Abstract: An after-treatment system including an exhaust treatment component provided in an exhaust passage, a tank carrying an aqueous reagent, and an electrochemical cell in communication with the tank and configured to receive the aqueous reagent therefrom. The electrochemical cell is configured to convert the aqueous reagent into a first exhaust treatment fluid and a second exhaust treatment fluid. A controller is in communication with the electrochemical cell. The controller is configured to vary amounts and/or composition of each of the first exhaust treatment fluid and the second exhaust treatment fluid produced by the electrochemical cell. An injector is in communication with the electrochemical cell and the exhaust passage, and is configured to receive one of the first exhaust treatment fluid or the second exhaust treatment fluid from the electrochemical cell, and dose the one exhaust treatment fluid into the exhaust passage at a location upstream from the exhaust treatment component.

Abstract: A muffler includes a shell, baffles, and a plurality of pipes. The shell defines first and second end cavities and a central cavity. The end cavities have larger cross-sectional areas that a cross-sectional area of the central cavity. The baffles cooperate to form multiple chambers within the shell. A first inlet directs a first portion of the exhaust into a first chamber. A second inlet directs a second portion of the exhaust into a second chamber. A first pipe extends through first, third and fourth baffles and includes an inlet in the fourth chamber. The first pipe directs exhaust from the fourth chamber to a first outlet at the first end cavity. A second pipe extends through the second, third and fourth baffles and includes an inlet in the third chamber. The second pipe directs exhaust from the third chamber to a second outlet at the second end cavity.

Abstract: An assembly may include first and second components and a service flange. The first component has a first opening. The second component has a second opening in communication with the first opening. The service flange may be mounted to the first component such that the first component is disposed between the service flange and the second component. The service flange extends around the periphery of the first opening and may include a plurality of separate and discrete segments that are individually secured to the first component. Adjacent segments define joints that movably connect the segments together while allowing for relative movement between the segments before the first component is secured to the second component. The segments include mounting apertures spaced apart from the joints and receiving fasteners configured to fixedly secure the first component to the second component. Each fastener only engages a single segment of the service flange.

Abstract: A shock absorber is disclosed having a pressure tube forming a working chamber, and a piston assembly slidably disposed within the pressure tube. The piston assembly may divide the working chamber into upper and lower working chambers. The piston assembly may have a piston body defining a first fluid passage extending therethrough and a first valve assembly controlling fluid flow through the first fluid passage. A second fluid passage, separate from the first fluid passage, extends from one of the upper and lower working chambers to a fluid chamber defined at least in part by the pressure tube. A plurality of digital valve assemblies are included and configured to exclusively control all fluid flow through the second fluid passage, and thus all fluid flow between the one of the upper and lower working chambers to the fluid chamber.

Abstract: An exhaust treatment system includes first and second exhaust conduits positioned on opposite ends of an exhaust treatment device. The exhaust treatment device includes a housing having a first outer diameter at a first end and a different second outer diameter at a second end. A clamp includes an inner surface engaging both the first exhaust conduit and the exhaust treatment device when the exhaust treatment device is positioned with its first end adjacent to the first exhaust conduit. The inner surface of the clamp is spaced apart from one of the housing and the exhaust treatment device when the second end of the exhaust treatment device is adjacent the first exhaust conduit.

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 shock absorber for a vehicle may include a piston and a valve disc assembly. The piston defines a plurality of passages extending through the piston between an upper working chamber and a lower working chamber of a fluid chamber. The valve disc assembly engages the piston and controls a flow of fluid between the upper working chamber and the lower working chamber through the plurality of passages. The valve disc assembly includes a variable radius spring disc among a plurality of discs. The variable radius spring disc has a varying outer radius. The valve disc assembly has a stiffness that varies circumferentially based on the variable radius spring disc such that an actuation of the valve disc assembly with respect to the piston varies circumferentially.

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.
