Abstract

Un dispositivo de control de la relación de aire-combustible incluye un detector de la relación de aire-combustible configurado de tal manera que un valor de corriente de salida del mismo varía linealmente de conformidad con una concentración de oxígeno, y un medio de control de retroalimentación de la relación de aire-combustible capaz de ejecutar el control de retroalimentación de la relación de aire-combustible para controlar por retroalimentación una cantidad de inyección de combustible con base en un valor de detección del detector de la relación de aire-combustible de modo que el gas de escape de un motor de combustión interna alcance una relación de aire-combustible predeterminada. El dispositivo de control de la relación de aire-combustible adicionalmente incluye un medio de prohibición para prohibir el control de retroalimentación cuando la relación de aire-combustible alcanza o excede una relación de aire-combustible rica predeterminada. El dispositivo de control de la relación de aire-combustible permite el control de retroalimentación durante un periodo predeterminado después de que la relación de aire-combustible alcanza o excede la relación de aire-combustible rica predeterminada.
