Abstract
Un sistema de escape que incluye un convertidor catalitico, sistema de reduccion catalitica selectiva, un silenciador y, para determinadas aplicaciones, un filtro de particulas diesel que incluyen, cada uno, al menos un filtro que tiene un elemento de calentamiento electrico, un recubrimiento metalico y una pluralidad de barras de metal que se extienden a traves del mismo. La combinacion de elementos estan configurados para calentar los alojamientos internos del sistema de escape y perturbar la direccion de flujo de gases de escape que contienen gases toxicos y contaminantes perjudiciales y ayudar a eliminar y/o reducir dichos gases toxicos y contaminantes.
