Abstract
E' descritto un sistema digitale di regolazione del combustibile per un piccolo motore a combustione interna avente un sensore di pressione per rivelare la pressione istantanea nel collettore d'aria. Un microprocessore sensibile ai dati di pressione d'aria genera un segnale d'uscita che indica la quantità di combustibile da erogare al motore. Una apparecchiatura dosatrice di combustibile sensibile a tale segnale dosa il combustibile erogato nel collettore d'aspirazione d'aria del motore. Il microprocessore in risposta ai dati di pressione d'aria generati dal sensore di pressione determina la velocità del motore e la pressione media dell'aria. I dati relativi alla velocità del motore e alla pressione dell'aria indirizzano ad una tabella di ricerca per estrarre dati indicativi delle richieste di combustibile del motore.
