Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO Y UN EQUIPO DE ELIMINACION DE LOS OXIDOS DE NITROGENO PRESENTES EN LOS GASES DE ESCAPE PROCEDENTES DE UN MOTOR DE COMBUSTION INTERNA (1). DICHO EQUIPO FORMA PARTE DE LA LINEA DE ESCAPE (2) QUE SALE DEL MOTOR Y COMPRENDE: - UN MEDIO DE CONVERSION DE LOS OXIDOS DE NITROGENO, Y - UN CAMBIADOR TERMICO (4) SITUADO EN UN CONDUCTO DE DERIVACION (5) CON ANTERIORIDAD AL MEDIO DE CONVERSION (3) Y DESTINADO A ENFRIAR LOS GASES DE ESCAPE. SEGUN LA INVENCION, EL MEDIO DE CONVERSION CONSTA DE VARIOS CATALIZADORES (3) DISPUESTOS EN LA LINEA PRINCIPAL DE ESCAPE (2). DICHOS CATALIZADORES PRESENTAN CAMPOS DE TEMPERATURA NO UNIDOS, PARA LOS CUALES LA CONVERSION DE LOS OXIDOS DE NITROGENO ES INFERIOR A UN CIERTO UMBRAL (C MIN ); ADEMAS, EN LA EMBOCADURA DEL CONDUCTO DE DERIVACION (5) ESTA COLOCADA AL MENOS UNA VALVULA (6) DESTINADA A MODULAR EL CAUDAL DE GAS ENTRE DICHA LINEA DE DERIVACION (5) Y LA LINEA PRINCIPAL (2), PARA QUE LOS GASES DE ESCAPE LLEGUEN A LOS CATALIZADORES (3) A UNA TEMPERATURA EN QUE AL MENOS UNO DE ELLOS ESTE ACTIVO.
