Abstract

EL SILENCIADOR COMBINADO CON UN CONVERTIDOR CATALITICO CONSISTE EN UNA CAJA (12) INCLUYENDO UN ELEMENTO TUBULAR INTERNO (30) EN LA QUE SE FIJA UN CONVERTIDOR CATALITICO. LOS GASES DE SALIDA DEL MOTOR ENTRAN AL SILENCIADOR (10) A TRAVES DE UNA TOBERA VENTURI(20), FLUYENDO A TRAVES DE UNA SERIE DE DIAFRAGMAS (50,70,80) HECHOS DE MATERIAL CERAMICO POROSO TRATADO CON MATERIALES CATALITICOS, Y SALEN POR UN ORIFICO DE SALIDA (38) DEL SILENCIADOR DISMINUIDOS EN CONTAMINANTES. LOS DIAFRAGMAS DE CERAMICA PUEDEN TENER FORMA DE COPA Y POSEER AGUJEROS PASANTES (54,56,58) O FORMA OJIVAL (72) CON PAREDES PERFORADAS Y PUEDEN CONSISTIR EN ELEMENTOS FORMADOS POR UNA PLACA (82) CON BRIDAS LATERALES FORMANDO CAVIDADES OPUESTAS (90,100). LOS ELEMENTOS (50,70,80) PUEDEN ESTAR COMBINADOS ENTRE SI DE DIFERENTES MANERAS PARA FORMAR UNA SECUENCIA DE CAMARAS (V0,V1,V2...) CON LA FORMA Y VOLUMEN MAS ADECUADO PARA CADA TIPO DE MOTOR.
