Abstract

UN METODO PARA ACCIONAR UN CONVERTIDOR CATALITICO QUE INCLUYE UN CALENTADOR, PARA TRATAR LOS GASES DE ESCAPE DE UN MOTOR QUE CONSISTE EN QUE EN EL MOMENTO DE ARRANCAR EL MOTOR, SE ENERGICE EL CALENTADOR A UN NIVEL DE POTENCIA DE 1,5KW COMO MINIMO POR UNIDAD DE M{SUP,3}/MIN DE VELOCIDAD DE FLUJO DE LOS GASES DE ESCAPE, AL TIEMPO QUE SE SUMINISTRA UN GAS OXIDANTE AL CONVERTIDOR CATALITICO, Y CUANDO LA TEMPERATURA DEL CALENTADOR HA SOBREPASADO UN VALOR AL QUE FUNCIONA EL CATALIZADOR PRINCIPAL SOPORTADO SOBRE EL CALENTADOR, SE REDUCE EL NIVEL DE POTENCIA DEL CALENTADOR Y SE SUSPENDE EL SUMINISTRO DE GAS OXIDANTE.
