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.

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 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.

摘要: A method is provided for estimating the NOx content of exhaust gas produced by an internal combustion engine. The method includes determining a first NOx estimate corresponding to the NOx level output by the engine during a first engine operating condition. The method further includes determining a second NOx estimate corresponding to the NOx level output by the engine during a second engine operating condition. The method further includes determining a compensation factor based on intake manifold pressure and applying the compensation factor to the first and second NOx estimates to arrive at a final NOx estimate.
