Abstract
Perfeccionamientos en sistemas de control híbrido de doble modo de inyección de combustible para controlar el funcionamiento de un sistema electrónico de inyección de combustible para un motor de combustión interna que funciona a velocidades diferentes de rotación, caracterizados porque se dota a cada sistema de control híbrido de medios para generar una señal eléctrica de controlo para controlar el funcionamiento del sistema electrónico de inyección de combustible; medios comparadores de circuito cerrado acoplados a los medios generadores de la señal de control para establecer un modo de control en circuito cerrado con el fin de activar los medios generadores de la señal de control de modo que el sistema electrónico de inyección de combustible funcione normalmente en la relación estequiómetrica de aire/combustible, mientras que el motor funciona dentro de una gama predeterminada de velocidades, para conseguir una reducción óptima de las emisiones del motor; y medios comparadores de circuito abierto acoplados a los medios generadores de la señal de control y sensibles a la consecuencia de una velocidad del motor fuera de la gama predeterminada para cambiar a un modo de control en circuito abierto con el fin de fijar la señal de salida de los medios generadores de la señal de control a un valor predeterminado para que el sistema electrónico de inyección de combustible funcione en una relación de aire/combustible relativamente pobre con el fin de obtener una mejor economía de combustible.
