Abstract

Sistema elettronico (1) per il controllo di un turbocompressore a geometria variabile applicato ad un motore diesel, in cui un primo circuito (40) produce, in risposta a segnali di ingresso (N, FR, BP), un primo segnale di pilotaggio in anello chiuso alimentato ad un attuatore (31) che modifica le caratteristiche geometriche del turbocompressore. Il sistema comprende inoltre un secondo circuito (44) che riceve in ingresso un segnale misura (nT) proporzionale alla velocità di rotazione del turbocompressore e genera un secondo, segnale di pilotaggio che viene alimentato all'attuatore (31) quando il segnale di misura (nT) supera un valore limite memorizzato (nTmax).
