Abstract: A system and method relate to a reductant dosing for use in the reduction of NOx in an exhaust stream is disclosed. The system and method incorporates a separate first or start-up cartridge and an insulated mantel or housing containing at least one to a plurality of main cartridges. The first and main cartridges store an ammonia adsorbing/desorbing material, which releases ammonia gas upon application of sufficient heat. The start-up cartridge permits the initial release of ammonia gas into the exhaust stream even during start-up of an engine, and because it is separate from the main cartridge, the first cartridge cools faster than the main cartridge and can be replenished with ammonia sooner than the main cartridge. The start-up cartridge is housed in or surrounded by a non-insulating debris shield.

Abstract: Disclosed is a composition and method which facilitate increased incorporation of meat into a dry food product, such as an extruded pet food kibble. Products made by incorporating the composition provide increased resistance to breakage, excellent palatability, and increased nutritional value.

Abstract: A mount (50) for mounting an exhaust gas component (30, 32, 16) in an exhaust pipe (34) or in a component housing includes a spring band (54) and a plurality of spring fingers (64). The spring band (54) is configured to contact and substantially pass around an outer surface (52) of the exhaust gas component (30, 32, 16). The plurality of spring fingers (64) extend from the spring band (54) generally axially with respect to the exhaust gas component (30, 32, 16) and generally radially from the spring band. The spring fingers (64) contact the exhaust gas component (30, 32, 16).

Abstract: Dosing components (22, 24, 32) in an engine exhaust after-treatment system (18) that includes an SCR catalyst (20) are thermally managed by flowing engine coolant through a coolant passage in a urea injector (22) that injects aqueous urea into the after-treatment system, controlling a three-way valve (60) to selectively direct coolant flow leaving the urea injector to a first branch that is in heat exchange relationship with a tank (24) that holds a supply of aqueous urea and a supply pump module (32) that pumps aqueous urea from the tank to the urea injector, and a second branch that is not in heat exchange relationship with either the tank or the supply pump, and returning coolant from the branches to the engine cooling system.

Abstract: A method for heating solid ammonia (NH3) in a main unit (12) to deliver gaseous ammonia into the exhaust gas (EG) downstream of an engine (16) includes the steps of diverting at least a portion of the exhaust gas from the exhaust gas passageway (14), fluidly communicating the exhaust gas on a delivery line (28) from the exhaust gas passageway to the main unit, heating the solid ammonia with the exhaust gas, and fluidly communicating the exhaust gas on a return line (30) from the main unit to the exhaust gas passageway.

Abstract: A mixing device and method for a diesel exhaust system is disclosed having a chamber, a mixer within the chamber, and an injection tube supported on the mixer within the chamber. The mixer is positioned within the chamber adjacent an inlet and includes a plurality of angled blades to effect turbulent flow in a diesel exhaust stream entering the chamber through the inlet. The injection tube includes a plurality of injection points (e.g., openings) for discharging a reagent, such as gaseous ammonia (NH3), into the exhaust stream. The injection tube is curved, and more specifically it is coiled with the injection points spread along the length of the tube in order to deliver reagent across a section of the chamber perpendicular to the exhaust stream flow.

Abstract: A restraint device and method for securing an ammonia storage tank holder to a frame is disclosed. The restraint device includes first and second supports which sandwich about the holder in a parallel fashion. A connecting support attaches to and holds the first and second supports in a substantially parallel relationship about the storage tank holder, and is adjustable such that the second support is selectively movable to expand the perimeter of the holding space. The disclosed method includes the steps of affixing a first support having first and second ends to a frame of a vehicle, placing a storage tank holder into contact with at least one surface of the first support, placing a second support having first and second ends substantially parallel to the first support in contact with a surface of the storage tank holder opposite the first support, and securing the first and second supports.

Abstract: An alignment clamp (10) for aligning a pair of tubular members (16, 18) in a fixed, end to end relationship includes a clamp member (12) having a longitudinal axis (A), and a substantially annular interior surface (26) facing the longitudinal axis. The interior surface (26) includes a discontinuous raised surface (33) and at least one radial gap (34) between portions of the raised surface. At least one indicator key (14) is disposed on the at least one radial gap (34).

Abstract: A mounting boss (36) for mounting a spray injector (16) on an exhaust pipe (32) of a vehicle exhaust system (12) includes a first wall (38) and a second wall (44). The first wall (38) extends at an obtuse angle to an outer surface (40) of the exhaust pipe (32) and defines a first interior surface (42). The second wall (44) extends at an obtuse angle with the outer surface (40) of the exhaust pipe (32) and defines a second interior surface (46). The first interior surface (42) and the second interior surface (46) define a recirculation area (48) that is in fluid communication with the exhaust pipe (32). The recirculation area (48) has a decreasing cross-sectional area in the direction of the flow of exhaust gas in the exhaust pipe (12). An aperture (50) is disposes in the first wall (38) for receiving the spray injector (16).
