Abstract

SE PRESENTA UN APARATO PARA AMORTIGUAR EL RUIDO EN UN CONDUCTO DE ESCAPE QUE PERTENECE A UN MOTOR DIESEL (10), EL CONDUCTO (11) COMPRENDE UN SISTEMA (12) PARA LA INYECCION DE UN REACTIVO AL INTERIOR DE LOS GASES DE ESCAPE DE LA COMBUSTION DEL MOTOR. EL PRODUCTO TAMBIEN COMPRENDE AL MENOS UNA CAMARA DE REACCION (15) PARA DEPURAR CATALITICAMENTE LOS GASES DE ESCAPE, Y AL MENOS UN SILENCIADOR REACTIVO (18-20, 21, 22) EN COMUNICACION CON EL CONDUCTO DE ESCAPE, LA LONGITUD DE SILENCIADOR SE ADAPTA ACUSTICAMENTE A LA LONGITUD DE LA ONDA DE LAS ONDAS DE SONIDO QUE TIENEN QUE SER AMORTIGUADAS DENTRO DE UNA BANDA ESPECIFICA DE FRECUENCIAS. EL SILENCIADOR (18-20, 21, 22) COMPRENDE AL MENOS UNA CAMARA DE RESONANCIA (19; 21) QUE ESTA DISPUESTA DE FORMA CONCENTRICA AL SEGMENTO RECTO (17) DEL CONDUCTO DE ESCAPE (11) Y QUE ESTA CONECTADA AL CANAL POR MEDIO DE AL MENOS UNA ABERTURA (18; 22).
