摘要： A method for reducing NOx molecules in an exhaust flow within an exhaust aftertreatment system of an internal combustion engine includes storing NOx from the exhaust flow on a NOx storage component within an aftertreatment device exposed to the exhaust flow. When the exhaust flow includes molecular hydrogen, he stored NOx is released to create ammonia in the exhaust flow. In a selective catalytic reduction device that is downstream of the aftertreatment device, the created ammonia is utilized to reduce NOx in the exhaust flow.

摘要： An exhaust system includes main line that runs through a three way converter (TWC) and then a lean NOx trap (LNT). The exhaust system further includes a bypass line configured to bypass the TWC. The LNT includes catalyst that is non-uniformly distributed along the longitudinal axis. The catalyst is distributed such that storage sites are weighted toward the upstream end of the LNT and oxidation and reduction sites are weighted toward the downstream end of the LNT.

摘要： A method of sizing a light-off core supporting a fixed quantity of a light-off catalyst for an exhaust gas treatment system having an electric heater upstream of the light-off catalyst for heating the exhaust gas includes measuring the cumulative hydrocarbon or carbon monoxide emissions leaving the exhaust gas treatment system for multiple volumetric sizes of the light-off core in accordance with a heating strategy. Alternatively, a model of the treatment system may be used to predict the cumulative hydrocarbon or carbon monoxide emissions. The method further includes selecting the volumetric size of the light-off core that is associated with the lowest cumulative hydrocarbon or carbon monoxide emissions level from the measured or predicted hydrocarbon or carbon monoxide emissions when the exhaust gas is heated in accordance with the heating strategy. The heating strategy may include pre-crank heating, post-crank heating, or a combination of pre-crank heating and post crank heating.
