Abstract

SE PRESENTA UN APARATO DE PURIFICACION DE GASES DE ESCAPE QUE COMPRENDE UN TUBO DE EXPANSION Y UN CATALIZADOR FINO EN EL SISTEMA DE ESCAPE EN UN MOTOR DE COMBUSTION INTERNA. DOS ABERTURAS PARA DESCARGAR UN GAS DE ESCAPE SE FORMA EN LA PARED PERIFERICA DEL TUBO DE EXPANSION EN EL EXTREMO DEL MISMO SOBRE EL LADO CORRIENTE ARRIBA EN SU DIRECCION LONGITUDINAL, Y LAS PARTES CENTRALES DE UN CATALIZADOR FINO PERMEABLE AL GAS EN SU DIRECCION TRANSVERSAL SE DISPONEN SEPARADAMENTE ALREDEDOR DEL TUBO DE EXPANSION DE FORMA QUE SE OPONGAN A LAS ABERTURAS PARA EL GAS DE ESCAPE. AMBAS PARTES LATERALES DEL CATALIZADOR FINO ESTAN CURVADAS HACIA EL TUBO DE EXPANSION Y ESTAN SOLDADAS INTEGRALMENTE CON LA SUPERFICIE PERIFERICA EXTERIOR. LA PERIFERIA EXTERIOR DEL CATALIZADOR FINO SE SELLA MEDIANTE UNA PLACA DE SELLAMIENTO FINA COMO MIEMBRO DE SELLAMIENTO Y SE FORMA UNA ABERTURA EN LA PLACA DE SELLAMIENTO SOBRE EL LADO OPUESTO A LAS ABERTURAS PARA EL GAS DE ESCAPE DEL TUBO DE EXPANSION. UN TUBO DE COMUNICACION CUYO EXTREMO SUPERIOR ESTA FIJADO EN EL INTERIOR DE LA ABERTURA DE LA PLACA DE SELLAMIENTO FINA PENETRA A TRAVES DE UNA ABERTURA DE UNA CARCASA DE SILENCIADOR QUE ESTA DISPUESTA SUBSTANCIALMENTE ADYACENTE A, Y EN PARALELO AL TUBO DE EXPANSION. EL EXTREMO INFERIOR DEL TUBO DE COMUNICACION TIENE UNA SECCION EN FORMA DE U QUE ESTA ABIERTA HACIA EL LADO CORRIENTE ABAJO DE LA CARCASA DEL SILENCIADOR. DE ACUERDO CON ESTA CONSTRUCCION, EL GAS DE ESCAPE PUEDE PONERSE EN CONTACTO CON EL CATALIZADOR FINO SIN SER ENFRIADO POR EL TUBO DE EXPANSION O AFECTAD POR EL CALOR DE LA REACCION CATALITICA. ADEMAS, PUEDE MEJORARSE LAS PROPORCIONES DE LA PURIFICACION Y LA EFICIENCIA DE LA DEPURACION, Y PUEDE REDUCIRSE EL TAMAÑO DEL APARATO DE PURIFICACION DE LOS GASES.
