Abstract

UNA INSTALACION CATALIZADORA PARA LA DEPURACION DE GASES DE ESCAPE, ESPECIALMENTE EN AUTOMOVILES, POSEE UN DISPOSITIVO DE CONDUCCION DE LOS GASES DE ESCAPE ALINEADO EN EL LADO DE ADMISION SOBRE EL CATALIZADOR, CON EL QUE SE PUEDE CONDUCIR EL GAS DE ESCAPE QUE NO SE ENCUENTRA TODAVIA A PLENO CALOR DE FUNCIONAMIENTO SOBRE UNA ZONA LIMITADA LOCALMENTE DEL CAALIZADOR. SE CONOCEN DISPOSITIVOS DE CONDUCCION DE GASES DE ESCAPE DE ESTE TIPO QUE, EN FUNCION DE LA TEMPERATURA, MODIFICAN SU SECCION TRANSVERSAL DE SALIDA PARA SIMPLIFICAR LA ESTRUCTURA Y MEJORAR EL RENDIMIENTO DE TALES DISPOSITIVOS DE CONDUCCION DE GASES DE ESCAPE, ESTOS ESTAN CONFIGURADOS COMO TOBERAS AGRUPADAS EN FORMA DE SEGMENTO. LOS SEGMENTOS INDIVIDUALES DE LA TOBERA SE DOBLAN EN FUNCION DE LA TEMPERATURA EN DIRECCION RADIAL COMO LAS GOJAS DE UNA FLOR. PARA PODER MODIFICAR LA SECCION TRANSVERSAL DE SALIDA DE LA TOBERA AUTOMATICAMENTE COMO EN UNA FLOR QUE SE ABRE Y SE CIERRA, LOS SEGMENTOS ESTAN FABRICADOS DE BIMETAL O DE UN MATERIAL CON MEMORIA.
