Abstract

LA INVENCION SE REFIERE A UN CATALIZADOR PARA LA DEPURACION DE AIRE DE ESCAPE FORMADO POR UN CUERPO DE CERAMICA (1) DE ACCION CATALITICA CUYA SUPERFICIE CATALITICA ESTA COMPUESTA POR UNA SERIE DE CONDUCTOS (3) QUE ATRAVIESAN EL CUERPO DE CERAMICA Y UNA RESISTENCIA ELECTRICA DE CALEFACCION (2) PARA CALENTAR EL CUERPO DE CERAMICA A UNA TEMPERATURA CATALITICA DE ENCENDIDO . PARA PODER FABRICAR UN CATALIZADOR DE ESTE TIPO O SUS CONDUCTOS DE FORMA ADECUADA Y RACIONAL, LA INVENCION PROPONE CONFORMAR LA RESISTENCIA ELECTRICA DE CALEFACCION (2) COMO UNA SERIE DE PIEZAS DE RESISTENCIA ELECTRICA DE CALEFACCION EN FORMA DE U (2 ) DISTRIBUIDAS BASICAMENTE DE FORMA UNIFORME POR LA SECCION TRANSVERSAL DEL CUERPO DE CERAMICA (1), QUE PUEDE ESTAR CONFORMADO COMO UNA O VARIAS PIEZAS, ATRAVESANDO LAS RAMAS DEL TUBO EN U (4) LOS CONDUCTOS (3) DEL CUERPO DE CERAMICA (1). LOS EXTREMOS (4 ) DEL TUBO EN U QUE SOBRESALEN POR EL OTRO LADO DEL CUERPO DE CERAMICA (1) ESTAN UNIDOS CADA UNO A SU PIEZA CONTIGUA DE RESISTENCIA ELECTRICA DE CALEFACCION (2 ) PARA FORMAR ASI LA RESISTENCIA ELECTRICA DE CALEFACCION (2) COMPLETA.
