Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA DETERMINAR UN PARAMETRO DE UN REGULADOR LAMBDA, QUE SIRVE PARA EL DESPLAZAMIENTO DE MEZCLA RICA O POBRE, EN DEPENDENCIA DEL ESTADO DE SERVICIO ACTUAL EN CADA CASO DEL MOTOR DE COMBUSTION INTERNA REGULADO, CARACTERIZADO PORQUE: - PARA EL PARAMETRO DE REGULACION CONCERNIENTE SE DETERMINA UN VALOR BASICO DEPENDIENTE DEL VALOR ACTUAL DE AL MENOS UNA MAGNITUD DE SERVICIO PREDETERMINADA, TAL COMO LA QUE ES VALIDA PARA UNA REGULACION CON EMISION MINIMA DE GASES NOCIVOS EN SERVICIO ESTACIONARIO DEL MOTOR, - ESTE VALOR BASICO SE MODIFICA AL HABER VARIACIONES DEL ESTADO DE SERVICIO DEL MOTOR, CON UN VALOR DE TRANSICION QUE DECRECE CON EL TIEMPO.
