Abstract

Un convertidor catalítico para motores de combustion comprende un material de lámina de malla porosa hecha a partir de fibras de metal que tienen undiámetro de aproximadamente 1-30 micras revestidas con un catalizador y conformadas en corrugaciones,el material teniendo preferiblemente un volumen hueco deaproximadamente 80-95%. Las láminas adyacentes tienen corrugaciones, en un ejemplo, a 45° en direcciones opuestas con relacion a las direcciones de flujo deentrada y salida de gas. Las láminas crean turbulencia creando una caída de presion a través del material de lámina y causando que el gas de escape fluya através de los intersticios del material de lámina en contacto con elcatalizador en los intersticios. El material es de peso ligero, tiene baja masa y exhibe un buen calentamiento de arranque en frío en menos de 1 minuto. Lacaída de presion a través del convertidor, con turbulencia en el flujo de gas,es comparable con las estructuras de convertidor de panal del arte anterior queexhiben flujo laminar, usa menor cantidad de catalizador, es más eficiente y es más ligero. Se muestran varias realizaciones que emplean generadores de vorticepara proporcionar turbulencia además de orientacion de canal corrugada en zigzag o para proporcionar unas trayectorias de canal tortuosas para el flujo degas, para crear la turbulencia deseada.
