Abstract

Perfeccionamientos en sistemas de control electrónico para la administración de la relación de aire/combustible de un motor de combustión interna, cuya unidad de control electrónico comprende un dispositivo de calibración básico de circuito abierto para regular la relación de aire/combustible del motor en respuesta a los parámetros analógicos detectados del motor indicativos del flujo de aire másico y el flujo de combustible másico inducido en el motor, cuyo dispositivo de calibración básico regula la relación de aire/combustible detectando el flujo de aire másico o el flujo de combustible másico y calculando el otro a partir del programa de relación de aire/combustible, caracterizados porque comprenden además un dispositivo de calibración de circuito abierto que comprende un generador de funciones analógicas para recibir una pluralidad de entradas de señales analógicas representativas de varios parámetros de funcionamiento y condiciones del motor y para dar salida a señales de control analógicas para controlar la relación de aire/combustible del motor, medios de calibración de circuito cerrado que comprenden un generador de funciones digitales para recibir entradas digitales representativas de varios parámetros de funcionamiento y condiciones del motor y para dar salida a señales de control digitales al generador de señales analógicas, y un convertidor de D/A para convertir por lo menos una de las señales de control digitales en una señal de control analógica, comunicándose el generador de funciones digitales con el generador de funciones analógicas por las señales de control digitales convertidas y las señales de control digitales sin convertir.
