    摘要： A method and system that protects contained anhydrous ammonia, such as from theft or misuse. The contained anhydrous ammonia, for example is part of an ammonia storage and delivery system. The anhydrous ammonia is contained by its absorption into a solid absorbent material. A component is configured to interfere with unauthorized handling of the anhydrous ammonia, where the component is operatively engaged with the contained anhydrous ammonia.

    摘要： An aftertreatment system including a method which provides a selective catalytic reduction (SCR) catalyst disposed in an exhaust stream of an engine; determines that an ammonia pre-load condition for the SCR catalyst is present; determines a first amount of ammonia pre-load in response to the ammonia pre-load condition; injects an amount of ammonia or urea into the exhaust stream in response to the first amount of ammonia; and adsorbs a second amount of ammonia onto the SCR catalyst in response to injecting an amount of ammonia or urea, where the second amount of ammonia is either the injected amount of ammonia or an amount of ammonia resulting from hydrolysis from the injected amount of urea.
