Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO PARA LA EXPLOTACION DE UN CONVERTIDOR (2) CATALITICO CALENTABLE DE FORMA ELECTRICA CON UN CIRCUITO DISEÑADO PARA UNA POTENCIA ELECTRICA DESDE 0,5 HASTA 10 KW, COMPRENDIENDO UNA FUENTE (6) DE CORRIENTE, UN INTERRUPTOR (20) DE POTENCIA, UN CONVERTIDOR (2) CATALITICO CALENTABLE ELECTRICAMENTE Y CONDUCTORES (21,22,61,62) ELECTRICOS. DE AQUI EL INTERRUPTOR (20) DE POTENCIA ES EL REGULADOR COMPARTIDO, Y EL CONVERTIDOR (2) CATALITICO ES LA VIA DE REGULACION COMPARTIDA DE AL MENOS DOS CIRCUITOS DE CONTROL DIFERENTES, SIENDO EL VALOR DE REGULACION COMPARTIDO LA TEMPERATURA EN EL CONVERTIDOR (2) CATALITICO. EL CONTROL ELECTRONICO DISPUESTO EN LA UNIDAD (5) ELECTRONICA PERTENECE A VARIOS CIRCUITOS DE REGULACION. LA UNIDAD (5) ELECTRONICA CONTIENE MEDIOS PARA EL CHEQUEO DE LOS CIRCUITOS DE REGULACION Y LA SELECCION DE UN CIRCUITO FIABLE. ES POSIBLE DE ESTA FORMA COMPENSAR EN CASO DE AVERIA DE COMPONENTES INDIVIDUALES DE UN CIRCUITO DE REGULACION MEDIANTE CONMUTACION A OTRO CIRCUITO SIN RETROCESO RELATIVO A LA DISPONIBILIDAD DEL VEHICULO A MOTOR Y CUMPLIENDO CON LAS REGULACIONES DEL GAS DE EXHAUSTACION.
