Abstract

SILENCIADOR DESTINADO ESPECIALMENTE A MOTORES DE DOS TIEMPOS CON CATALIZADOR COLOCADO EN ORDEN POSTERIOR AL SILENCIADOR Y QUE CONSTA DE UNA CARCASA (1) PROVISTA DE UNA ADMISION Y UN ESCAPE (2, 3) Y ESTA DIVIDIDA POR MEDIO DE PAREDES DE SEPARACION (4) CON TUBOS DE CONEXION (5) EN VARIAS CAMARAS (I A III). ESTA CARCASA (1) ES ATRAVESADA POR LA CORRIENTE DE GASES VARIAS VECES A LOS QUE SE CAMBIA DE DIRECCION. EL ESCAPE (3) SE COMPONE DE UN TUBO INTERIOR PERFORADO (6) RODEADO A UNA CIERTA DISTANCIA POR UN TUBO EXTERIOR (7) Y LA CARCASA (1) CONSTA DE UNA DOBLE PARED CON UNA CAPA RESISTENTE AL CALOR ENTRE MEDIAS. PARA LOGRAR UN SILENCIADO MAS EFICAZ CON UNA MENOR TEMPERATURA DE LA SUPERFICIE, SE CONECTA UN RESONADOR DE PIPA (8) AL RESONADOR RESULTANTE ENTRE EL TUBO INTERIOR PERFORADO (6) Y EL TUBO EXTERIOR (7). ADEMAS LA PARED INTERIOR (9) DE LA CARCASA ES ONDULADA Y LA CAPA INTERMEDIA AMORTIGUADORA DE RUIDO (10) TENSA LA PARED INTERIOR (9) CONTRA LA EXTERIOR.
