Abstract

Un circuito de control para modificar en forma variable la velocidad de flujo de combustible dosificado a un motor por medio de un aparato de inyección de combustible para suministrar el combustible dosificado al motor de conformidad con señales de control proporcionadas en respuesta a la velocidad del motor y en respuesta a la temperatura de operación del motor y adicionalmente en respuesta a la posición de una válvula de mariposa que se puede colocar en posición variable dentro de un pasaje de inducción que conduce al motor, y que comprende un dispositivo sensor de oxígeno para analizar el gas de escape del motor y producir una señal en respuesta al análisis para indicar si es que la mezcla aire-combustible suministrada al motor es demasiado pobre o demasiado rica en términos de combustible, y un dispositivo de modificación de circuito para recibir la señal del dispositivo sensor de oxígeno, el dispositivo modificador de circuito después de recibir la señal del dispositivo sensor de oxígeno indica que se está suministrando una mezcla demasiado pobre al motor que tiene efectividad para operar en un modo de bucle cerrado para modificar la señal que se produce por la posición de la válvula de mariposa lo que aparentemente indica que la válvula de mariposa se encuentra abierta hasta un punto en el que es de la apertura real, el dispositivo de circuito modificador después de recibir la señal del dispositivo sensor de oxígeno indicando que se encuentra suministrando una mezcla aire-combustible demasiado rica al motor y con efectividad para operar en un modo de bucle cerrado para modificar la señal que se produce por parte de la válvula de mariposa con el objeto de crear de esta manera una señal de posición modificada de la válvula de mariposa lo que aparentemente indica que la válvula de mariposa se ha abierto hasta un punto menor que la apertura real.
