    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： Reductant delivery system having at least one canister containing reductant coupled, via delivery line, to after-treatment system having ammonia injector, is disclosed. Reductant includes ammonia adsorbing/desorbing material. Delivery line is connected at one end to ammonia injector and at another end detachably coupled by coupler to the canister. Controller may be used for metering flow of ammonia through delivery line to injector. Line-break detector detects disconnection within the delivery line to prevent loss of ammonia. Line-break indicator coupled to line-break detector is used, wherein the indicator activates upon the detector detecting a disconnection in the delivery line. Related methods for detecting and indicating a line break are disclosed.

    摘要： An ammonia flow modulator having a housing, a fluid passage, a first valve, preferably having a precision orifice, positioned within the passage, and an orientation which prevents fluid from pooling in the passage is disclosed and claimed. As an added feature, the device may include a heat source positioned within the housing proximate at least one of a fluid inlet, a fluid outlet, and the fluid passage. The heat source may be provided by an electric heating element, an exhaust gas heat exchanger, or any other suitable source. As econd inlet and a second passage fluidly connecting the second inlet to the outlet by fluidly linking the second passage to the first passage and including a check valve to prevent backflow. A controller coupled to the first valve is used to control ammonia flow.

    摘要： A method of providing hydrocarbons to an engine exhaust for regenerating a diesel particulate filter within an exhaust system of a diesel engine. A mass flow rate of exhaust gas within an exhaust system is determined. A mass flow rate of oxygen within the exhaust gas entering the diesel oxidation catalyst is determined. A set point indicative of an allowable mass flow rate of oxygen within the exhaust gas exiting the diesel oxidation catalyst is received. A hydrocarbon threshold that may be injected into the exhaust system is calculated. Hydrocarbons are injected into the exhaust system upstream of the diesel oxidation catalyst, wherein the injected hydrocarbons do not exceed the calculated threshold amount of hydrocarbons.
