Abstract

Il sistema comprende un collettore aspirazione aria 2 che presenta un condotto principale 3 provvisto di una farfalla 4, un condotto bypass 5 dotato di una valvola di regolazione 6 e con due luci definite nel condotto principale a monte e a valle della farfalla, mezzi 25 di comando della valvola, sensori 8 e 11 del numero di giri motore e della massa d'aria aspirata dal motore, e mezzi che elaborano il segnale di comando della valvola in base al regime del motore. Il sistema comprende mezzi che elaborano la posizione teorica che la valvola assume in base al regime ed al carico del motore, mezzi che elaborano la posizione stimata in base ai rilevamenti dei sensori che la valvola assume dopo l'esecuzione del comando, mezzi che comparano la posizione teorica e quella stimata per generare un segnale errore, e mezzi che variano il segnale di comando della valvola in base al segnale errore.
