Abstract
Un método que comprende ajustar una cantidad de inyección de combustible sobre la base de un estado de oxidación fraccionario del catalizador, el estado de oxidación fraccionario basado en las velocidades de reacción de especies de gas de escape agrupadas oxidantes y reductoras a lo largo del catalizador y un modelo basado en la física de reducida dimensión derivado de un modelo detallado bidimensional a fin de obtener un modelo unidimensional promediado en tiempo y espacio que representa las limitaciones de difusión en el recubrimiento rugoso y que pronostica con exactitud las emisiones durante un arranque en frío.
