Abstract

UN SISTEMA DE CONTROL DE MEZCLA DE DILUCION AUTOADAPTABLE PARA MOTORES DE COMBUSTION INTERNA QUE INCLUYE UN APARATO PARA MEDIR UNA FUERZA DE COMBUSTION EN UNA CAMARA DE COMBUSTIBLE COMUNICANDO CON UN APARATO PARA CALCULAR EL POTENCIAL DE TRABAJO EN TIEMPO REAL DEL MOTOR DESDE LA FUERZA DE COMBUSTION MEDIDA, Y UN APARATO PARA CONTROLAR LA DILUCION VARIABLE DE LA MEZCLA COMBUSTIBLE-AIRE DESARROLLADA EN LA CAMARA DE COMBUSTION PARA LLEVAR A CABO UN POTENCIAL DE TRABAJO DESEADO, EL APARATO DE CONTROL RESPONSABLE DEL POTENCIAL DE TRABAJO EN TIEMPO REAL. EL APARATO PARA CONTROLAR LA DILUCION DE LA MEZCLA DE COMBUSTIBLE-AIRE VARIABLE INCLUYE UN COMPENSADOR PARA COMPARTIR EL POTENCIAL DE TRABAJO EN TIEMPO REAL Y OTROS PARAMETROS DEL MOTOR PARA UN MODELO DE CONTROL DE OPTIMIZACION AUTOADAPTABLE, Y CALCULAR EL POTENCIAL DE TRABAJO DESEADO. TAMBIEN SE INCLUYE UN SISTEMA DE INYECCION DE COMBUSTIBLE, Y UNA VALVULA DE RECIRCULACION DE ESCAPES PARA VARIAR LA DILUCION DE LA MEZCLA DE COMBUSTIBLE-AIRE PARALLEVAR A CABO EL POTENCIAL DE TRABAJO DESEADO. EL MODELO DE CONTROL DE OPTIMIZACION AUTOADAPTABLE ESTA ADAPTADO PARA CAMBIAR EN EL TIEMPO BASANDOSE EN UN CAMBIO EN LAS CONDICIONES DEL MOTOR.
