Abstract

Perfeccionamientos en reguladores de relación de aire/combustible para motores de combustión interna, cuyo sistema comprende: un regulador de la relación de aire/combustible para regular la relación de aire/combustible del motor de combustión interna de acuerdo con un cálculo basado en un programa de combustible predeterminado y la detección de por lo menos un parámetro de funcionamiento del motor, y un dispositivo regulador integral para modificar la regulación del regulador de relación de aire/combustible con una señal de corrección de circuito cerrado, en cuyo sistema el dispositivo regulador responde a la señal de salida de los niveles de un sensor de gases de escape, aumentando por incrementos el dispositivo regulador la relación de aire/combustible del motor cuando el sensor detecta una condición rica y de salida a un primer nivel, y reduciendo por incrementos la relación de aire/combustible del motor cuando el sensor detecta una condición pobre y da salida a un segundo nivel; caracterizados porque se dispone un dispositivo de modificación de gobierno para regular la autoridad del dispositivo regulador integral entre un valor máximo y un valor mínimo que depende del valor absoluto de la magnitud de error del sistema.
