Abstract

Este dispositivo de control para un motor de combustión interna está equipado con: un sensor de la relación aire/combustible proporcionado al paso de escape de un motor de combustión interna; y un dispositivo de control de motor que controla el motor de combustión interna de acuerdo con la salida del sensor de la relación aire/combustible. El sensor de la relación aire/combustible está equipado con: una cámara de gas que será medido, en el que fluye el gas de escape; una celda de la bomba que bombea oxígeno dentro o fuera de la cámara de gas que será medida de acuerdo con la corriente de bomba; y una celda de referencia de la cual la corriente de salida celda de referencia detectada varía en función de la relación de aire/combustible dentro de la cámara de gas a medir. La celda de referencia está equipada con: un primer electrodo que está expuesto al gas de escape en la cámara de gas a medir; un segundo electrodo expuesto a una atmósfera de referencia; y una capa de electrolito sólido dispuesto entre los electrodos. El sensor de la relación de aire/combustible está equipado con: un dispositivo de aplicación de voltaje de la celda de referencia que aplica un voltaje de sensor aplicado entre los electrodos; y un dispositivo de detección de corriente de salida de la celda de referencia que detecta, como la corriente de salida de la celda de referencia, la corriente que fluye entre los electrodos.
