Abstract

CONVERTIDOR CATALITICO PARA PURIFICAR GASES DE ESCAPE DE UN MOTOR DE COMBUSTION INTERNA. CONSISTE EN UN CONVERTIDOR MONOLITICO DE CERAMICA FRANGIBLE MONTADO ELASTICAMENTE EN UN ALOJAMIENTO METALICO. EL ELEMENTO MONOLITICO ESTA ENVUELTO EN UNA CAPA TERMICAMENTE AISLANTE DE FIBRAS CERAMICAS, CAPAZ DE SOPORTAR UNA EXPOSICION CONTINUADA A ELEVADAS TEMPERATURAS. UNA CAPA DE MATERIAL INTUMESCENTE DISPUESTA ENTRE EL ALOJAMIENTO Y LA CAPA DE FIBRAS CERAMICAS ASEGURA DE MANERA ELASTICA EL ELEMENTO MONOLITICO EN EL ALOJAMIENTO.
