Abstract

APARATO (1) EN QUE SE PROPORCIONA UN SENSOR (10) EN UN CONDUCTO DE ESCAPE (5) ENTRE EL COLECTOR DE ESCAPE DE UN MOTOR DIESEL (7) Y UN FILTRO CERAMICO (3). EL SENSOR (10) COMPRENDE UN PAR DE ELECTRODOS (14) ESPACIADOS ENTRE SI Y QUE SE PUEDEN CONECTAR ELECTRICAMENTE POR MEDIO DE LA MATERIA PARTICULAR CONTENIDA EN EL GAS Y DEPOSITADA EN EL SENSOR (10). EL SENSOR (10) TAMBIEN COMPRENDE UN ELEMENTO (16) ADAPTADO PARA REGENERARLO MEDIANTE EL QUEMADO PERIODICO DE LA MATERIA PARTICULAR CUANDO LA CONDUCTANCIA ENTRE LOS ELECTRODOS (14) EXCEDE UN VALOR UMBRAL. EL SENSOR (10) ESTA CONECTADO A UN PROCESADOR ELECTRONICO (12) QUE ASEGURA LA MEDIDA DEL NUMERO (S) DE REGENERACIONES DEL SENSOR (10) PARA ASI EMITIR UNA SEÑAL DE ATASCO CUANDO DICHO NUMERO (S) IGUALA UN VALOR LIMITE PREVIAMENTE ALMACENADO (SMAX). DE ESTE MODO, PUESTO QUE EL NUMERO (S) DE REGENERACIONES DEL SENSOR SE CORRELACIONA CON EL NUMERO DE PARTICULAS QUE FLUYEN A LA TUBERIA (5) Y ASI AL FILTRO (3) SE LLEVA A CABO UNA EVALUACION INDIRECTADEL GRADO DE ATASCADO DEL FILTRO (3).
