  • Publication number: 20160356192
    Abstract: Systems and methods for tracking and indicating a status for the deliverable reductant, such as ammonia, in a canister used in an exhaust gas after-treatment system are disclosed. An on-board system provides a visual display to indicate either generally or specifically the fill-status of each of a plurality of loaded ammonia canisters, while a separate canister system is able to be periodically updated while on-line and, using a memory device such as a RFID tag, carry the updated fill-status even when it is removed from the vehicle system. The residing memory device can be read off-line to determine the ammonia fill-status. Metering of the ammonia flow allows real-time monitoring and updating of the canister status.

  • Patent number: 9322695
    Abstract: Systems and methods for determining amount of solid ammonia stored in a canister used in providing ammonia fluid in exhaust gas after-treatment systems. A microcontroller sets an ammonia level based on the data read from an RFID tag associated with the canister. The data may provide the amount of solid ammonia stored in the canister or a tag number that the microcontroller may use to retrieve the quantity of stored solid ammonia. A measured amount of ammonia fluid used during the treatment process may be used by the microcontroller in determining the amount of solid ammonia depleted from the canister. At predetermined precisions, the amount of depleted ammonia is subtracted from the set ammonia level to determine the remaining amount of solid ammonia in the canister. This determined amount of may be used to reset the ammonia level and be written onto the RFID tag.

  • Patent number: 9174167
    Abstract: A reductant mixing system having injector and mixing plate positioned within mixing canister is disclosed. Injector discharges reductant directly into vehicle exhaust gases. Mixing plate effects turbulence to mix gases for NO reduction. Mixing plate includes plurality of arms each having surface area and extending from center of plate, barrier region defined by collective surface areas of arms and substantially centered for diverting fluid flow outward, and first and second cut-outs, which allow the gases diverted by barrier region to pass mixing plate into adjacent canister of exhaust treatment system. Each of the first cutouts is defined by outer edge between adjacent arms, and second tier of cut-outs defined by inner edge proximate end of each arm.

  • Publication number: 20150101675
    Abstract: A reductant storage and dosing system which uses at least one canister containing a supply of reductant to supply, via a delivery line, an exhaust gas after-treatment system having an injector is disclosed. A controller may be used to meter the flow of the reductant through the delivery line to the injector, while a status indicator indicates a status of the connection—i.e., connected or disconnected. In an embodiment, the status indicator provides a visual signal or indication, such as an LED or series of LEDs, an audible signal, such as a beep, click or buzz, or both. Iternatively, the status indicator may be an analog or digital gauge.

  • Patent number: 8549849
    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.

  • Patent number: 7168415
    Abstract: A vehicle chassis with at least two fuel tanks with each of the fuel tanks having fuel level detector or sender. The level senders are engaged to an electronic controller. The individual tank draw lines from each tank come together at a control valve that has a single outlet that leads to an engine. The control valve can be open from one of the tanks at a time to the engine. An electronic controller takes the inputs from the fuel senders and compares levels between the tanks to control the valve. The system defaults or starts drawing from a primary tank and upon the level in the primary tank falling to a pre-specified amount below the level in a secondary tank, the electronic controller shifts the control valve to draw from the secondary tank or vice versa on a secondary tank level drop.
