摘要： A method of sizing a heating core of an exhaust heater for an exhaust gas treatment system includes measuring the cumulative hydrocarbon or carbon monoxide emissions from the exhaust gas for multiple volumetric sizes of the heating core when heated 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 heating 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, or a combination of pre-crank heating and post-crank heating.

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.
