Abstract

LA INVENCION SE REFIERE A UN CONVERTIDOR CATALITICO CALENTADO ELECTRICAMENTE QUE DISPONE DE UNA CARCASA CONTENIENDO AL MENOS UNA DISPOSICION (10) DE CUERPO EN FORMA DE PANAL A TRAVES DEL CUAL LOS GASES DE COMBUSTION PUEDEN FLUIR A PARTIR DE UN MOTOR DE COMBUSTION INTERNA EN UNA DIRECCION. LA DISPOSICION (10) DE CUERPO DE PANAL ES ELECTROCONDUCTIVA Y ELECTROCALENTABLE ELECTRICAMENTE EN AL MENOS AREAS PARCIALES, DISPONIENDO DE UN RECUBRIMIENTO ACTIVO CATALITICAMENTE SOBRE AL MENOS ALGUNAS AREAS PARCIALES. LA DISPOSICION (10) DE CUERPO EN FORMA DE PANAL ESTA SUBDIVIDIDA POR MEDIO DE RANURA (16) Y/O ZONAS ELECTROCONDUCTIVAS POBRES, DE TAL FORMA QUE AL MENOS DOS AREAS (11,13,15) PARCIALES ELECTROCONDUCTIVAS SUCESIVAS CON DIFERENTES LONGITUDES AXIALES (LH1, LH2, LH3) Y/O DIFERENTES RESISTENCIAS ELECTRICAS SE ENCUENTRAN EN LA DIRECCION DEL FLUJO. ESTE DISEÑO ES ADAPTABLE MAS FACILMENTE A DIAMETROS DIFERENTES Y A POTENCIAS ELECTRICAS, MIENTRAS MANTIENE UNA BUENA RESISTENCIA MECANICA. PERMITE TAMBIEN UNA ESTANDARDIZACION DE LOS PERFILES ESTRUCTURALES PARA LA TOTALIDAD DE CONDICIONES MARGINALES DIFERENTES A FIN DE MINIMIZAR LA EMISION DE PARTICULAS PULULANTES EN LA FASE DE ARRANQUE EN FRIO.
