Abstract

Sistema di controllo della quantità di carburante iniettato per un sistema di iniezione (4) elettronica, in cui una unità di calcolo (10) fornisce il valore (Qb) della quantità di benzina da iniettare per avere un rapporto stechiometrico aria/benzina sostanzialmente corretto. Tale valore (Qb) viene successivamente corretto mediante un coefficiente (Ko2), calcolato integrando un segnale (E) comprendente un segnale (A) fornito da una sonda lambda (21) presenta una funzione di trasferimento comprendente una caratteristica non lineare ad un ritardo puro che influenza notevolmente la velocità di risposta del sistema, il sistema comprende inoltre una unità di calcolo (26) simulante la funzione di trasferimento del sistema motore-sonda lambda per generare un segnale (B) che simula l'andamento del segnale prodotto realmente dalla sonda lambda (21) ed è privo del tempo di ritardo (T) introdotto dalla sonda e dal sistema.Tale segnale (B) viene utilizzato per produrre un segnale correttore (D) che viene sommato al segnale generato dalla sonda lambda (21) per recuperareil tempo di ritardo (T) e migliorare la risposta dinamica di tutto il sistema.
