Abstract

SE PRESENTA UN METODO PARA ESTIMAR LA EFICIENCIA DE UN SISTEMA DE REDUCCION DE LAS EMISIONES CONTAMINANTES DE UN MOTOR DE COMBUSTION INTERNA (1) QUE CONTIENE UNA PLURALIDAD DE COMPONENTES PROVISTOS DE SENSORES DE CONTROL (6, 7, 9); EL METODO COMPRENDE LAS SIGUIENTES ETAPAS: LA CAPTURA DE UNA PLURALIDAD DE VALORES DE LAS SEÑALES EMITIDAS POR LOS SENSORES (7, 6, 9) O RESULTANTES DEL PROCESAMIENTO DE OTRAS SEÑALES GENERADAS POR LOS SENSORES (6, 7, 9); EL CALCULO DEL INDICE DE RELACION DE ESA PLURALIDAD DE VALORES CON UN CONJUNTO DE CATEGORIAS PREDEFINIDAS POR DEFECTO MEDIANTE UNA FUNCION POLINOMIAL DE INDICES DE RELACION PREDETERMINADA, DE TAL FORMAQUE CADA UNA DE LAS CATEGORIAS TIENE ASOCIADOS UN VECTOR DE COEFICIENTE UTILIZADO POR LA FUNCION POLINOMIAL DE INDICES DE RELACION PARA EL CALCULO DEL INDICE DE RELACION Y UN ESTADO DE EFICIENCIA DEL SISTEMA PARA REDUCIR LAS EMISIONES CONTAMINANTES QUE ES CARACTERISTICO DE LA CATEGORIA RESPECTIVA; Y LA ASOCIACION CON LA PLURALIDAD DE SEÑALES DEL ESTADO DE EFICIENCIA QUE ES CARACTERISTICO DE LA CATEGORIA QUE TIENE EL INDICE DE RELACION MAS ALTO CON LA PLURALIDAD DE VALORES.
