Abstract

Viene descritto un procedimento per l'impostazione della pressione di alimentazione in un motore a combustione interna sovralimentato per mezzo di un turbocompressore con distributore di turbina regolabile su un valore nominale di pressione di alimentazione prestabilito, dipendente dal punto di funzionamento. Per migliorare il rendimento del motore a combustione interna nel funzionamento non stazionario, in particolare dopo una variazione di carico positiva da bassi campi di carico e di numero di giri viene proposto di regolare, dopo una variazione positiva di carico, durante il funzionamento non stazionario al disotto di un valore di soglia prestabilito per la contropressione dei gas di scarico a monte della turbina, la pressione di alimentazione secondo una prima curva caratteristica corrispondente alla differenza momentanea effettiva del valore reale della pressione di alimentazione dal valore nominale della pressione di alimentazione e, dopo aver superato questo valore di soglia, di regolare la contropressione dei gas di scarico, inoltrando al circuito di regolazione della pressione di alimentazione differenze fittizie di regolazione secondo una particolare curva caratteristica.
