Abstract

Procedimiento y aparato para regular el funcionamiento de un motor de combustión interna con encendido por chispa, en condiciones más pobres que la estequiometria, procedimiento caracterizado porque comprende, verificar de una forma continua el grado de ionización de los gases de escape del motor, por medio de un detector de ionización que da una señal de voltaje de salida correspondiente al grado de ionización, y que deriva de la señal de salida del detector de ionización una señal de realimentación que se utiliza para controlar la pobreza de la mezcla de combustible suministrada a la cámara de combustión del motor.
