Abstract: This technology provides methods and systems for catalyst feasibility analysis and the optimal determination of automotive catalyst specifications utilizing, but not limited to, light-off performance, air-to-fuel ratio tolerance, and steady state emissions performance catalyst criteria. This technology additionally provides a catalyst feasibility index algorithm that includes various catalyst criteria inputs and provides for weighting factors to independently value each catalyst input. The technology further provides for the optimal determination of automotive catalyst specifications in order to reduce vehicle toxic exhaust emissions such as hydrocarbons (HC) and oxides of nitrogen (NOx).
