Abstract

Se proporciona sistema de pos tratamiento de escape para vehículos motorizados con motor de combustión interna. Un sistema incluye una lógica en la forma de una o más rutinas ejecutadas por uno o más de los componentes del sistema para la determinación de la cantidad de NO2 presente en el escape que sale de un catalizador de oxidación, tal como un catalizador de oxidación diésel (DOC), sin la utilización de un sensor de NO2. Los result6ados de una determinación pueden entonces ser utilizados para estimar la cantidad de hollín presente en el filtro de partícula. Este valor estimado de hollín presente en el filtro de partículas puede ser utilizado posteriormente para determinar cuándo el filtro de partículas debe ser regenerado activamente.
