Abstract

Perfeccionamientos en circuitos de regulación de combustible para motores de combustión interna, del tipo que disponen que tiene una placa de mariposa, caracterizados porque comprenden medios para detectar la magnitud de las irregularidades del funcionamiento del motor de combustión interna y generar una señal de irregularidad proporcional a la magnitud de irregularidad, siendo la señal de irregularidad representativa de la relación instantánea de aire/combustible del motor, medios sensores de la mariposa para detectar el régimen de cambio del ángulo de la placa de la mariposa del motor de combustible interna y generar una señal de la mariposa proporcional dicho régimen de cambio, y medios de enriquecimiento de aceleración para generar impulsos de enriquecimiento de aceleración cuya frecuencia es proporcional a la magnitud deseada de aceleración del motor de combustión interna, siendo sensibles los medios de enriquecimiento de aceleración a la señal de irregularidad de funcionamiento para aumentar la cantidad de enriquecimiento de aceleración para la señal de irregularidad por encima de un umbral y para reducir la cantidad de enriquecimiento de aceleración para la señal de irregularidad por debajo del umbral, respondiendo además los medios de enriquecimiento de aceleración a la señal de la mariposa, dependiendo la frecuencia del impulso de enriquecimiento de aceleración de la señal de irregularidad y de la señal de la mariposa.
