Abstract

Un sistema di controllo a loop chiuso integrato, senza mappatura e auto adattativo per motori endotermici comprende: un dispositivo di carburazione (1) dotato di strumenti di erogazione controllata del carburante; sonde lambda (8) disposte nello scarico del motore; una marmitta catalitica (7); una unità centrale di comando (9) che elabora segnali elettrici per agire sugli strumenti di erogazione; il dispositivo dì carburazione (1) comprende inoltre un dispositivo per la misura della portata d'aria; in base a un programma, l'unità (9) agisce sugli strumenti di erogazione per impostare il titolo della miscela in funzione della portata d'aria e dei valori dei segnali provenienti da sensori (R.P.M., Tm, Ta, U, Pa) e della depressione esistente a valle della valvola di strozzamento (13) e per controllare la carburazione in funzione dei valori dei segnali delle sonde lambda (8) in modo da mantenere il titolo della miscela in un valore ottimale per ogni condizione di funzionamento del motore.
