摘要： 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.

摘要： 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.

摘要： A system for mixing ammonia (reductant) with engine exhaust includes an exhaust flow created by a vehicle engine, an ammonia feed line passing into the exhaust flow, an injector connected to the feed line and positioned within the exhaust flow, the injector having at least one port for discharging ammonia into the exhaust flow, and a mixing plate positioned within the exhaust flow downstream of the ammonia injector and stabilizing at least one of either the feed line and the injector. An aspect of the invention is to stabilize the injector by attaching the mixing plate to the feed line to provide such stability. Alternatively or additionally, the mixing plate is attached to the injector to stabilize. The feed line may even pass through the mixing plate.
