摘要： A diesel engine (10) has an exhaust system (16) containing a diesel particulate filter (18) for trapping soot passing through the exhaust system as the engine operates. A trapped soot estimator (30) estimates soot trapped in the diesel particular filter by repeatedly executing an algorithm that calculates a data value for total soot trapped using Kalman filter processing (48) whose gain is controlled by at least one engine operating parameter.

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.

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.
