Abstract: An aftertreatment system may treat exhaust gas discharged from an engine. The system may include first and second selective-catalytic-reduction (SCR) catalysts and a valve. The valve may be disposed upstream of the first SCR catalyst and at least one of an oxidation catalyst and a particulate filter. The valve is connected to first and second exhaust flow paths and is movable between a first position allowing exhaust gas to flow through the first flow path and bypass the second flow path and a second position allowing exhaust gas to flow through the second flow path and bypass the first flow path. The second SCR catalyst may be a low-temperature SCR catalyst and may be disposed in the second flow path. A control module may cause the valve to move between the first and second positions based on a temperature of the exhaust gas and/or a temperature of the engine.

Abstract: A stabilizer comprises a damper having a housing and a piston rod. An inner adapter is associated with the damper for securing a first end of the damper to one of a first component or a second component. An outer adapter assembly is coupled to a distal end of the piston rod for coupling to the other of the first and second component. A one-piece spring seat is coupled to the housing of the damper so as to be held axially stationary relative to the housing. A coil spring is supported by the one-piece spring seat and the outer adapter assembly. The one-piece spring seat enables the coil spring to return the stabilizer to a neutral position regardless of whether the coil spring is under tension or compression.

Abstract: An exhaust after-treatment system includes an exhaust treatment component, a tank for holding an exhaust treatment fluid, and an exhaust treatment fluid dosing system. The dosing system includes a fluid distributor providing exhaust treatment fluid under pressure to a plurality of dosing modules that dose exhaust treatment fluid into the exhaust stream and a return for returning unused exhaust treatment fluid to the tank. A valve is positioned between the fluid distributor and the return and is configured to allow a flow of exhaust treatment fluid from the return to the fluid distributor before being returned to the tank during a purge operation. A controller is configured to open the valve and allow communication between the return and the fluid distributor during the purge operation such that unused exhaust treatment fluid drains during the purge operation.
