Abstract

UNA SONDA (8) DE GASES DE ESCAPE MUESTRA UN ELECTRODO DE MEDICION (3) CON EL QUE PUEDE MEDIRSE LA RESISTENCIA DE UNA CAPA DE OXIDO METALICO (4). LA CAPA DE OXIDO METALICO (4) MUESTRA UNA REDUCIDA ACTIVIDAD CATALIZADORA. LA RESISTENCIA DE LA CAPA DE OXIDO METALICO (4) DEPENDE, PARA UNA PROPORCION DE AIRE PREDETERMINADA, DE LA PRESION PARCIAL DE OXIGENO EN EL GAS DE ESCAPE. LA TASA DE CONVERSION DE UN CATALIZADOR (7) INFLUYE EN LA PRESION PARCIAL DE OXIGENO EN EL GAS DE ESCAPE DESPUES DEL CATALIZADOR, DE TAL FORMA QUE LA RESISTENCIA DE LA CAPA DE OXIDO METALICO (4) DEPENDE DE LA CAPACIDAD DE CONVERSION DEL CATALIZADOR. CON LA SONDA DE GASES DE ESCAPE DE ESTRUCTURA SENCILLA PUEDE COMPROBARSE MEDIANTE UNA SENCILLA MEDICION DE LA RESISTENCIA, LA CAPACIDAD DE FUNCIONAMIENTO DEL CATALIZADOR.
