Control device of the position of an element having an influence on the richness of the fuel - air mixture of a combustion engine

摘要

P the invention relates to the regulation of the operation of the butterfly valve of a combustion engine. / p & & p & the operation of the butterfly valve is controlled by a servo-motor depending on the output of a differential amplifier. The device comprises a diode is placed between the input of a reference value and the input of the real value of the amplifier, a resistor connected between the junction of the input of the value of consigna with the diode and with the generator of the reference value, and a capacitor connected between the junction point and the ground (circuit r - c). / p & & p & application: improvement of the dynamic stability of the regulation of a combustion engine. / p
